Answer:
According to the law of conservation of energy, energy cannot be created or destroyed, although it can be changed from one form to another. KE + PE = constant. A simple example involves a stationary car at the top of a hill. As the car coasts down the hill, it moves faster and so it’s kinetic energy increases and it’s potential energy decreases. On the way back up the hill, the car converts kinetic energy to potential energy. In the absence of friction, the car should end up at the same height as it started.
This law had to be combined with the law of conservation of mass when it was determined that mass can be inter-converted with energy.
One can also imagine the energy transformation in a pendulum. When the ball is at the top of its swing, all of the pendulum’s energy is potential energy. When the ball is at the bottom of its swing, all of the pendulum’s energy is kinetic energy. The total energy of the ball stays the same but is continuously exchanged between kinetic and potential forms
The Stratosphere contains the highest concentration of the ozone, this is because the ozone is located here. The Thermosphere has the highest average air temperature also seen as the hot layer, and the Mesosphere is the lowest average sir temperature.
Object mass =mk<span>g
</span>acceleration due to gravity of Mars = gm m/
acceleration due to gravity on Earth ge=−9.8 m/
weight of an object on Earth=m×ge=350N
weight of an object on Mars=m×gm=134<span>N
</span>
m x gm = 134
m x ge = 350
gm = 134/350 x 9.8 m/ = 3.752 m/
Answer:
i assume the system is in equilibrium
Explanation:
(W_p-T)(2)+W_b(2.5)= T(sin 45 degrees)(5)
T(((sin 45 degrees)(5)) + 2) = (W_p)(2) + W_b(2.5)= T(5.5355)
