Answer:
a bowling ball because it has the most mass.
When firing straight up:
v^2 = u^2 - 2gh, where v = final velocity = 0, u = initial velocity, g = gravitational acceleration, h = maximum height attained.
Then,
0 = u^2 - 2gh
u = Sqrt (2gh) ---- (1)
When firing at 45°,
Initial velocity, U = u Sin 45 = Sqrt (2gh)·Sin 45
Maximum height, H = U^2*(Sin Ф)^2/2g
substituting;
H = [Sqrt (2gh)·Sin 45]^2*(Sin 45)^2]/2g
H = [2gh*(Sin 45)^2*(Sin 45)^2]/2g
H = [h*(Sin 45)^4] = h/4
Therefore, maximum height when the gun fires at 45° is a quarter of maximum height when the gun fires vertically up.
Yes, if the temperature increases, than that means the particles are moving faster. Temperature is the measure of movement of particles in an object or substance.
By thermal energy, you mean adding heat correct....? I'm not very good at this sort of thing, but I gave you what I have..
Answer:
pulling force
Explanation:
because the person is pulling that cart.
A group of objects that orbit a star is called a planet.
<h3>What is star?</h3>
A small sized object that enlightens in the night sky in the infinite universe.
The group of objects is a large sized object which orbits a star called Sun.
This group of object is called planets.
Thus, a group of objects that orbit a star is called a planet.
