Answer:
<h2>150 kg.m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 10 × 15
We have the final answer as
<h3>150 kg.m/s</h3>
Hope this helps you
Answer:
geothermal energy
Explanation:
the energy is obtained from the heat within the surface of earth
Explanation:
(a) According to the law of conservation of energy,
Potential energy = Kinetic energy
mgh =
Putting the given values into the above formula as follows.
mgh =
h = 0.9 m
Therefore, the height H is 0.9 m.
(b) For the given situation,
Kinetic energy = work done by friction
u = 0.3
Thus, we can conclude that the coefficient of kinetic friction on the horizontal surface is 0.3.
The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now (and it could still be stretching).
Explanation:
the vector of the coordinates is
11+13 = 24 m East
7 m North
