The relevant equation we can use in this problem is:
h = v0 t + 0.5 g t^2
where h is height, v0 is initial velocity, t is time, g is
gravity
Since it was stated that the rock was drop, so it was free
fall and v0 = 0, therefore:
h = 0 + 0.5 * 9.81 m/s^2 * (4.9 s)^2
<span>h = 117.77 m</span>
Explanation:
Use the formula:
e is the energy released,
m is the mass of water,
c is the specific heat capacity,
δθ is the change in temperature ( 100 - 22)
Answer:
actually quantity of matter present in a body is its mass.
Acceleration= v/ r
So you have to divide 700 by 0.800 which is equal to 875 m/s 2
Answer:
A. True
Explanation:
Type la supernova can be described as a phenomenon whereby two stars are in orbit with one another .
Recently , two prominent research groups came to the same surprising conclusion after taking measurements of the luminosity of Type Ia supernovae at great distances that the universe is accelerating while it expands.
