Answer:
D
Explanation:
heat is an energy that transfers from a hot body to cold body
Answer:
1039.23 m/s
Explanation:
Given:
Height, H = 3 x 10⁵m
acceleration of gravity on lo, a = 1.80 m/s² toward moon's surface i.e -1.80m/s² with respect to the earth
Now, at its highest point the velocity i.e the final velocity 'v' = 0m/s.
Now using the Newton's equation of motion
v² - u² =2as
where,
v = final velocity
u = initial velocity
a = acceleration
s = distance
now,
substituting the values we get
0²-u² = 2 × (-1.80) × 3 x 10⁵
or
Hence, the <u>initial velocity</u><u> with which the material is ejected is </u><u>1039.23 m/s</u>
True: Friction depends on the types of surfaces involved and how hard the surfaces push together.
