You throw a baseball with a mass of 0.5 kg. The ball leaves your hand with a speed of 35 m/s. Calculate the kinetic energy. (SHOW ALL WORK)
Answer:
The kinetic energy of the baseball is 306.25 joules.
Explanation:
SInce the baseball can be considered a particle, that is, that effects from geometry can be neglected, the kinetic energy ([tex]K[/tex]), in joules, is entirely translational, whose formula is:
[tex]K = \frac{1}{2}\cdot m\cdot v^{2}[/tex] (1)
Where:
[tex]m[/tex] - Mass, in kilograms.
[tex]v[/tex] - Speed, in meters per second.
If we know that [tex]m = 0.5\,kg[/tex] and [tex]v = 35\,\frac{m}{s}[/tex], then the kinetic energy of the baseball thrown by the player is:
[tex]K = \frac{1}{2}\cdot m \cdot v^{2}[/tex]
[tex]K = 306.25\,J[/tex]
The kinetic energy of the baseball is 306.25 joules.

When the image of an object is seen in a plane mirror, the distance from the mirror to the image depends on?
A. The Wavelength of light used for viewing
B. The distance from the object to the mirror
C. The distance of both the observer and the object to the mirror.
When the image of an object is seen in a plane mirror, the distance from the mirror to the image depends on the distance from the object to the mirror.
It is because a Plane Mirror is the incident ray, the reflected ray, and the normal to the surface all lie in the same plane, and the angle of incidence is equal to the angle of reflection. So, the distance from the object to the mirror equals the distance from the image to the mirror. Thus whoever the person viewing this image must sight at this image location.

answer is A:14
Explanation:
The temperature of the thermometer which reads 57 °F in degree celsius (°C) to the nearest whole number is 14 °C
Conversion formulaWe can convert from degree celsius (°C) to degree Fahrenheit (°F) with the following equation
°C = 5/9(°F – 32)
How to determine the temperature in degree celsius (°C) Temperature (°F) = 57 °FTemperature (°C) =?°C = 5/9(°F – 32)
°C = 5/9(57 – 32)
°C = 5/9 × 25
°C = 14 °C
Thus, the temperature in degree celsius (°C) of the thermometer is 14 °C

A man supports himself and the uniform horizontal beam pulling the rope with a force T.The weights of men and the beam are 883 N and 245 N respectively.Calculate the tension T in the rope and the forces exerted by the pin at A.
Answer:
T=502.5N
Ax=171.8N
Explanation:
The computation of the tension T in the rope and the forces exerted by the pin at A is shown below:
vertical forces sum = Ay + Tsin20 + T - 245 - 883 = 0
Now
horizontal forces sum = Ax - Tcos70
Now Moment about B
-Ay × 4.8 + 245 × 2.4 + 883 × 1.8=0
Ay=453.6N
Now substitute in sum of vertical forces T=502.5N
Ax=171.8N
a. The tension (T) in the rope is equal to 502.51 Newton.
b. The forces exerted by the pin at A is equal to 171.86 Newton.
Given the following data:
Weight of men = 883 N Weight of beam = 245 NTo calculate the tension (T) in the rope and the forces exerted by the pin at A:
First of all, we would determine the vertical force by taking moment about point B as shown in the diagram.
[tex]-A_y \times 4.8 + 883 \times 1.8 + 245 \times 2.4 =0\\\\-4.8A_y + 1589.4 + 588 =0\\\\4.8A_y= 3237\\\\A_y=\frac{2177.4}{4.8} \\\\A_y= 453.63 \;Netwon[/tex]
The tension (T) in the rope would be calculated by the sum of the vertical component of forces, which is given by:
[tex]\sum F_x = A_y + Tsin20 + T - 245 - 883 = 0\\\\453.63 + 0.3420T + T -1128=0\\\\1.3420T = 1128-453.63\\\\1.3420T =674.37\\\\T =\frac{674.37}{1.3420}[/tex]
Tension, T = 502.51 Newton.
To find the forces exerted by the pin at A, we sum the vertical component of forces, which is given by:
[tex]\sum F_y = A_x - Tcos70 =0\\\\A_x =Tcos70\\\\A_x = 502.51 \times cos70\\\\A_x = 502.51 \times 0.3420\\\\A_x = 171.86\;Newton[/tex]

Imagine carefully weighing a metal can, leaving it out in the rain for weeks and weeks
until it was very rusted, and then carefully weighing it again. Would the can be heavier or lighter after it was rusted? Why?
Answer:
The can would be heavier.
Explanation:
The more rust is on the can, (Or object) the more it weights it down.
Answer:
The answer would be heavier, though it depends upon the type of metal. Rusting is essentially corrosion. Rust is often caused by a piece of metal getting soaked in water and then being exposed to oxygen. The rust will add more weight to the can so it becomes heavier.
Calculate the speed of a periodic wave that has a wavelength of 2.0 m and a frequency of 3.0 Hz.
Answer:
v=wavelength x f = 2 x 3 = 6 m/s
Explanation:
The speed of a wave is the product of its frequency and wavelength. The speed of the periodic wave with the frequency of 3 Hz and wavelength of 2 m is 6 m/s.
What is frequency?Frequency of a wave is the number of wave cycles per unit time. It is the inverse of the time period of the wave. Frequency is inversely proportional to the wavelength of the wave.
The relation between speed, frequency and wavelength of a wave is given by the expression as written below:
c =νλ
where, c is the speed, ν be the frequency and λ be the wavelength.
Given that ν = 3 Hz or 3 s⁻¹
and λ = 2 m
then speed c = 2 m × 3 Hz = 6 m/s
Therefore, the speed of the periodic wave is 6 m/s.

What does a charged object experience as it is placed into an electric field?
Answer:
In an electric field a charged particle, or charged object, experiences a force. If the forces acting on any object are unbalanced, it will cause the object to accelerate. With this in mind: If two objects with the same charge are brought towards each other the force produced will be repulsive, it will push them apart.

Compare the density of a 1,000,000 kg iceberg to that of a 10 g ice cube taken from the
iceberg. Explain your answer.
ANYONE ASAPP ITS SO IMPORTANT PLSSS
Answer:
The density of the 1,000,000 kg iceberg = The density of the 10 g iceberg
Explanation:
The given quantities of iceberg that will be the basis of the comparison of the densities of the iceberg;
The mass of the iceberg = 1,000,000 kg
The mass of the ice cube taken from the iceberg = 10 g
The density of a substance, is the measure of the mass of the substance per volume of the substance, it is a constant for the substance
[tex]Density = \dfrac{Mass}{Volume}[/tex]
For the iceberg, the density of the iceberg is the property that indicates the volume occupied by a given mass of the iceberg
Because of density, we can estimate that the volume occupied by a 1,000 kg iceberg is 10 times the volume occupied by a 100 kg iceberg
We can write
The density of the 100 kg iceberg = 100 kg/(x m³)
The density of the 1,000 kg iceberg = 1,000 kg/(10 × x m³) = 100 kg/(x m³)
Therefore, the density of the 100 kg iceberg = The density of the 1,000 kg iceberg
Similarly,
The density of the 1,000,000 kg iceberg = The density of the 10 g iceberg because the 10 g iceberg was obtained from the 1,000,000 kg iceberg, and therefore, they have the same density.
What happens, if anything, when you change the mass of the planet? Why do you think the mass of the planet does, or does not, affect the orbit of the planet?
Answer:
We know that the gravitational force between two objects of mass M1 and M2 that are at a distance R, is given by:
F = G*(M1*M2)/R^2
Where G is a constant.
If you reduce one of the masses, then the gravitational force between the objects will change.
So if we take un account the Earth and the Sun, when you reduce the mass of Earth, the force between Earth and the Sun will decrease, and this will change the orbit of the Earth around the Sun.
(The orbit also depends on the gravitational force between the Earth and the other planets in the system, and all those forces also change, which also has an impact in the orbit change)
