The energy the Sun gives off is caused by nuclear reactions in its core. The extreme pressure from the weight of the gases that make up the Sun raises the temperature of the core enough for the nuclear reactions to take place. Which law best describes this behavior of gases in the Sun?
Answer:
The law which describes the behavior of gases in the Sun is Gay-Lussac's Law
Explanation:
The states that the extremely high pressure of the gases in the Sun produces extremely high temperature;
Therefore, the relationship between the pressure, 'P', of the gas and the temperature, 'T', of the gas is a direct relationship, which can be expressed mathematically as follows;
P ∝ T
The law which best describes the behavior of gases in the Sun is Gay-Lussac's Law, which states that the pressure of a given volume of gas varies directly as the absolute temperature of the gas, as follows;
P = K·T
∴ P/T = K (Constant)
[tex]\therefore \dfrac{P_1}{T_1} = \dfrac{P_2}{T_2}[/tex]

During the course of a trajectory, is the vertical component of the velocity a constant or a changing value? ___________________ If it is a changing value, then describe its changes (increasing, decreasing, or ...)
Answer:
1) Changing value
2) The velocity is decreasing for upward motion and increasing for downward motion due to gravitational force
Explanation:
1) A trajectory is the motion of an object which is being acted upon by specified forces. The flight path of an object in projectile motion is its trajectory
During the course of a trajectory, the vertical component of the velocity, [tex]v_y[/tex], is a changing value
2) The vertical component of the velocity first decreases, during the upward motion, according to the following equation;
[tex]v_y[/tex] = [tex]u_y[/tex] - g·t
Where;
[tex]v_y[/tex] = The vertical component of the velocity after a given time, t
[tex]u_y[/tex] = The initial vertical velocity
t = The time of motion of the trajectory
g = The acceleration due to gravity ≈ 9.8 m/s²
When the vertical velocity of the object decreases to zero, which is the point at which the object reaches the maximum height of its motion, the direction of the vertical motion of the object reverses, and object begins to accelerate and increase its velocity downwards according to the following equation;
[tex]v_y[/tex] = [tex]u_y[/tex] + g·t
Therefore, the velocity of the object is decreasing on its way up, and then increasing on its way down.

An object accelerates at 8 m/s^2 when a force of 40 Newtons is
applied to it. What is the mass of the object? (Use formula: m=Fla)
Answer:
5 kg
Explanation:
Acceleration = 8 m/s^2
Force = 40 N
Force = mass * acceleration
mass = force / acceleration
mass = 40 / 8
mass = 5 kg

1. If two objects each with the mass of 2.0 x 10^2 kg, produce gravitational force between
them of 3.7 x 10^-6N , What is the distance between them ?
Answer:
r = 0.849 m
Explanation:
Given that,
The masses of two objects, [tex]m_1=m_2=2\times 10^2\ kg[/tex]
The force between the objects, [tex]F=3.7\times 10^{-6}\ N[/tex]
We need to find the distance between the masses. The force between two objects is given by the relation as follows :
[tex]F=G\dfrac{m_1m_2}{r^2}[/tex]
r is the distance between them
[tex]r=\sqrt{\dfrac{Gm_1m_2}{F}} \\\\r=\sqrt{\dfrac{6.67\times 10^{-11}\times (2\times 10^2)^2}{3.7\times 10^{-6}}} \\\\r=0.849\ m[/tex]
So, the distance between them is 0.849 m.
A motorist is driving at a constant velocity of 28.0 m/s when he decides to pass a car is in front of him. He accelerates at a rate 2.50 m/s2 for 3.00 seconds while passing the car. What is his velocity at the end of the 3.00 seconds?
Answer:
Final velocity, V = 35.5m/s
Explanation:
Given the following data;
Initial velocity = 28m/s
Acceleration = 2.5m/s²
Time = 3 seconds
To find the final velocity, we would use the first equation of motion
V = U + at
Where;
V is the final velocity measured in m/s.
U is the initial velocity measured in m/s.
a is the acceleration measured in m/s².
t is the time measured in seconds.
Substituting into the equation, we have;
V = 28 + 2.5*3
V = 28 + 7.5
Final velocity, V = 35.5m/s
How can a volcano develop in the middle of a tectonic plate?
Answer:
Volcanoes that form away from plate boundaries are created by hotspots. A hotspot is an area in the mantle that is believed to be somewhat hotter than the surrounding material. The rising magma from the hotspot can push its way through the crust and burst out at the surface, forming a volcano.
Explanation:
Volcanoes can form in subduction zones, which are regions where tectonic plates are interacting one and plate is sinking beneath the other.
Essay about how volcanoes form.A volcano is a hill or mountain in the shape of a cone that is erected around a fissure in the surface of the earth thru which heated gases, rock fragments, and lava are released. A conical mass grows around the conduit as the solid fragments gather there, becoming progressively larger until it reaches the size of a gigantic volcanic mountain.
Explain what a volcano is.A volcano is an aperture or vent through which magma, tephra (small rocks), or steam are released onto the the planet's surface. Days, weeks, or even years might pass between outbursts of volcanoes.

What does the potential energy of an object depend on?
Answer:
The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds.

Your teacher gives you samples of the following elements. Which sample is shiny but does not conduct heat and electricity well? (DOK 2)
A.
fluorine (F)
B.
silver (Ag)
C.
germanium (Ge)
D.
neon (Ne)
Fluorine is the sample which is shiny but does not conduct heat and electricity through it. The flow of electricity requires the flow of electrons or charged particles. Thus, the correct option is A.
What are conductors?
A conductor is a substance, chemical element, or a material which allows electricity and heat to flow through it. In a conductor, the electrical charge carriers which are usually electrons or positive and negative ions, move easily from one atom to another atom when a particular amount of voltage is applied.
Fluorine is a shiny element however it does not conduct heat and electricity through it. It is the most electronegative atom and is very reactive in nature. It only gains electrons and does not lose them. And because of this property of fluorine, it restricts the movement of electrons through it and fails to conduct electricity.
Therefore, the correct option is A.

If the half-life of tritium (hydrogen-3) is 12.3 years, how much of
a 10 g sample of tritium is present after 250.0 years?
Answer:
0.0000076 grams
Explanation:
We're given the half life of Tritium to be 12.3 years. In order to find out the amount of substabce remaining:
Let's first find how many 'half lives' are in 250 years.
[tex]n = \frac{250}{12.3} = 20.325[/tex]
Now what is half life? It means the time taken for a given quantity of an element to lose half it's mass.
So in 12.3 years we can find that The amount of 250 g of Tritium will be 250/2 = 125 g. In 24.6 years we'll have 125/2 = 62.5 g
So now we can devise a formula:
[tex]m = \frac{original \: amount}{ {2}^{n} } [/tex]
Where m is the remaining amount and n is th number of half lives in the time given.
Using this formula we can calculate:
[tex]m = \frac{10}{ {2}^{20.325} } [/tex]
Doing this calculation we get:
[tex]m = 0.0000076 \: g[/tex]
As we can see a very small value remains.

A group of friends are going bowling. They discuss how ball weight and speed can change the amount of
kinetic energy transferred to the pins.
They can use a 6 pound, 10 pound or 12 pound ball.
They can roll the ball at 10 miles per hour (beginner), 14 miles per hour (intermediate) or 18 miles per hour (professional) speed.
A. Describe a strategy that they could use to transfer the greatest amount of kinetic energy to the pins.
B. Explain the relationship between kinetic energy and strategy that you chose in part A.
C. Draw a model that demonstrates the energy transfers that occurred in the system.
Answer:
A. you would want to use the 12 ound ball and the 18 mph speed in order to transfer the most kinetic energy
B. KE= 1/2 MV^2 so you would want to maximize both your Mass(weight of the ball) and Velocity(speed of the roll) in order to achive the greatest KE.

Calculate the running costs of a filament lamp with a 60 W bulb and a CFL lamp with a 15 W bulb for 15 hours.
1 kWh costs 10p.
cost = power (kW) × time (hours) × price (per kWh)
Answer:
the cost of running the bulbs is 11.25p
Explanation:
Given;
cost of running 1 kwh = 10 p
power of filament bulb, P = 60 W
power of the CFL bulb, P = 15 W
time of power consumption, t = 15 hours
Total Energy consumed;
E = (60W + 15W) x 15 hours
E = (75)(15)
E = 1125 Wh
E = 1.125 kWh
Cost of 1.125 kWh = 1.125 x 10p
= 11.25p
Therefore, the cost of running the bulbs is 11.25p
