How much time does it take for a spinning baseball with an angular speed of 38 rad/s to rotate through 15 degrees
Answers
Answer:
the time of motion of the ball is 6.89 ms.
Explanation:
Given;
angular speed, ω = 38 rad/s
angular distance, θ = 15 degrees
Angular distance in radian;
[tex]\theta = 15^0 \times\frac{2\pi \ rad}{360^0} = 0.2618 \ rad[/tex]
Time of motion is calculated as;
[tex]time = \frac{angular \ distance}{angular \ speed} \\\\t= \frac{\theta}{\omega} = \frac{0.2618 \ rad}{38 \ rad/s} \\\\t = 6.89 \ \times 10^{-3} \ s\\\\t = 6.89 \ ms[/tex]
Therefore, the time of motion of the ball is 6.89 ms.

Electric Field Hockey
In this activity, you will again explore the relationship between an electric field and charged particles in the field, but this time you’ll have a gaming challenge. To begin, open Electric Field Hockey.
Directions:
On the control bar, make sure that the Puck is Positive and the Field boxes are checked. Also, make sure that the Practice option is selected.
Your aim is to score goals by manipulating the black puck (test charge) into the blue-colored bracket (goal) on the right. Think smart and place positive source charges (red) and negative source charges (blue) in such a way that the black puck moves into the goal.
Note that when you place a red, positive source charge in the hockey field, a red arrow appears on the black puck (test charge) showing the force the positive charge exerts on the puck. Similarly, when you place a blue, negative source charge in the hockey field, a blue arrow appears on the black puck (test charge) showing the force the negative charge exerts on the puck.
Question 1
Part A
Place a red charge on the hockey field and click Play. In which direction do electric field lines point? In which direction does the black puck move? What conclusion do you draw from this movement?
Part B
Click Reset and then click Clear. Now, place a blue charge in the hockey field and click Play. In which direction do electric field lines point? In which direction does the black puck move? What conclusion do you draw from this movement?
Part C
Manipulate the mass of the puck by dragging the mass bar to the right to increase the mass and to the left to decrease it. What changes do you see in the speed of the puck? Which principle works behind this change?
Part D
In the same situation, what do you observe about the relationship between the speed of the black puck and its distance from the blue charge?
Question 2
You can make the puck travel in complex ways by placing a set of charges around on the field. So, here’s your game challenge: Arrange sources charge around to propel the puck from its starting position into the goal. That’s pretty easy for a straight shot; you just put a negative charge behind the goal. But what if there are barriers along the way? This is a real test of your physical understanding, including Newton’s laws of motion and electrostatic forces. Game’s on!
Part A
On the control bar, check the Trace and Field boxes. The game has three Difficulty levels. Start with Difficulty level one and arrange source charges to get the puck into the goal. Once you’ve made a score at any level, increase the Difficulty level. Take a screen capture of two of your most difficult goals and paste them here. At least one of these should be at Difficulty level 2 or 3.
Please Answer Questions with complete sentences.
Answers
Answer:
The positive charges point away from each other
Explanation:
Why?
Arrows point away from the positive charge and toward the
negative charge.
Explanation:
Suppose that you rubbed a balloon with a sample of animal fur such as a wool sweater or even your own hair. The balloon would likely become charged and its charge would exert a strange influence upon other objects in its vicinity. If some small bits of paper were placed upon a table and the balloon were brought near and held above the paper bits, then the presence of the charged balloon might create a sufficient attraction for the paper bits to raise them off the table. This influence - known as an electric force - occurs even when the charged balloon is held some distance away from the paper bits. The electric force is a non-contact force. Any charged object can exert this force upon other objects - both charged and uncharged objects. One goal of this unit of The Physics Classroom is to understand the nature of the electric force. In this part of Lesson 1, two simple and fundamental statements will be made and explained about the nature of the electric force.
Perhaps you have heard it said so many times that it sounds like a cliché.
Opposites attract. And likes repel.
These two fundamental principles of charge interactions will be used throughout the unit to explain the vast array of static electricity phenomena. As mentioned in the previous section of Lesson 1, there are two types of electrically charged objects - those that contain more protons than electrons and are said to be positively charged and those that contain less protons than electrons and are said to be negatively charged. These two types of electrical charges - positive and negative - are said to be opposite types of charge. And consistent with our fundamental principle of charge interaction, a positively charged object will attract a negatively charged object. Oppositely charged objects will exert an attractive influence upon each other. In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart. Similarly, a negatively charged object will exert a repulsive force upon a second negatively charged object. Objects with like charge repel each other.
The activity where to explore the relationships between the electricity field charged with particles and those of the hockey field
The positively change will attract to each other and will opposite to the negatively changed ones. Arrows point away from the positive charge and toward the negative charge.Learn more about the you will again explore the relationship.

Group of answer choices
heating from the crust and mantle
heating from the core and mantle
cooling from the crust and core
cooling from the core and mantle
Answers
Answer: Heating from the crust and mantle.
Explanation: Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.
The convection currents that cause this cycle to take place is driven by heating from the crust and mantle. Hence, option (a) is correct option.
What is rock cycle?A crucial idea that illustrates the changes between the three primary rock types is the "rock cycle" (metamorphic, igneous and sedimentary). Simply put, it is a series of processes that create and modify the various types of rocks found in the Earth's crust.
The solid crust of Earth serves as a heat insulator for the planet's warm interior. The molten rock in the mantle, below the crust, is known as magma. Convection currents are created by the intense heat and pressure that exists within the earth. The tectonic plates that make up the earth's crust shift as a result of these currents.

help plss .. Two bicyclists are accelerating forward in a straight line, and Biker 1 has less
mass than Biker 2. If the net force on the bikers is the same, which statement
describes their acceleration?
Answers
Explanation:
Remember Newton's Second Law.
[tex]F=ma[/tex]
If the force acting on both bikers is the same, we can look at the relationship between acceleration and mass.
If Biker 1 has a mass of 10kg and Biker 2 has a mass of 20kg, and both are being acted upon by a force of 100 N, let's see what that looks like. [tex]100 = 10*a_1 \rightarrow a_1 = 100/10 = 10[/tex]
[tex]100 = 20 *a_2 \rightarrow a_2 = 100/20 = 5[/tex]
So, given the same force, an object with GREATER mass will have less acceleration.

Within a few sentences, explain the difference between meiosis and mitosis.
Answers
Mitosis and meiosis are both processes which describe the production of new cells. Mitosis produces 2 daughter cells which are genetically identical to the parent cell. Each daughter cell is diploid (contains the normal number of chromosomes). This is the result of DNA replication and 1 cell division. Mitosis is used in growth and asexual reproduction. Meiosis produces 4 daughter cells, each of which are unidentical to the parent cell and to one another. Each daughter cell is haploid (contains half the number of normal chromosomes). This is the result of DNA replication, followed by crossing over of homologous chromosomes and separation of chromosomes. There are two cell divisions: the parent cell divides once and then each cell produced by this first division divides once. Meiosis is used to produce gametes (sperm and egg cells), the cells of sexual reproduction. Two gametes fuse to form a zygote, a diploid cell with the full number of chromosomes.

Good luck to you!
The point in the compass needle has the opposite polarity from Earth’s north pole. The correct option is B.
What is a compass needle?The compass needle A magnetized pointer within a compass that can freely align with the Earth's magnetic field.
The magnetic needle is the most important part of the compass. It swings around the compass as you move, but the red end always points north and the white (or sometimes black) end always points south.
If you mean the geographical North Pole, the needle would point south because that is the only way to get there; more specifically, it would point south along the 112.4 degrees west longitude meridian towards the magnetic north pole at 82 degrees north, where compasses point.
Thus, the correct option is B.

particle has 17.5 joules of kinetic energy and 12.5 joules of gravitational potential energy at one point during its fall from a tree to the ground. An instant before striking the ground, how much mechanical energy — rounded to the nearest joule — does the particle have?
Answers
Answer:
Em = 30 J
Explanation:
The principle of conservation of mass and energy is one of the most important in physics, it establishes that energy cannot be created just by transforming it.
Therefore, the mechanical energy at a point is the same throughout the movement, only in some parts it will be kinetic, in others potential and in the intermediate points a mixture of the two, but the total value is always the same.
Em = K + U
Em = 17.5 + 12.5
Em = 30.0 J
At the point just before touching the ground the mechanical energy is the same Em = 30 J
