Answer:
0 kgm/s
Explanation:
The momentum is the product of mass(m) and velocity(v).
Initially the velocity of truck is 0 m/s so the product of mass and velocity becomes 0.
It does not matter what is the weight of truck, because the velocity will make the product of m*v = 0
It does not matter what is the momentum of car.
Period is T = 1/f. The frequency, f, is 5cycles/10s = 0.5. So the period T=1/0.2 = 2.
Explanation:
A force that leads to movement of an object is known as work.
The energy present in an object due to its position in a gravitational field is known as gravitational potential energy.
Kinetic energy is the energy obtained by an object due to its motion.
For example, when Jerome is swinging on a rope then there occurs movement in the swing due to which the swing has kinetic energy.
Since, a force has been applied on the swing to make it move. Hence, a work is also done.
Therefore, we can conclude that if Jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, work is being done.
Answer:
84 protons and 128 neutron
Answer:
<h2>
$228</h2>
Explanation:
Given data
Total electricity consumption = 2400 kWh
Rate of consumption = 9.5 cent per kWh
converting cent to dollar we have. 9.5/100= $0.095
hence the bill is 2400*0.095= $228
