Many ways, but some of the most famous are kicks (side, back, front, snap) or a smash.
Hope it helped! :)
Answer:
Option A
Explanation:
This can be explained based on the conservation of energy.
The total mechanical energy of the system remain constant in the absence of any external force. Also, the total mechanical energy of the system is the sum of the potential energy and the kinetic energy associated with the system.
In case of two stones thrown from a cliff one vertically downwards the other vertically upwards, the overall gravitational potential energy remain same for the two stones as the displacement of the stones is same.
Therefore the kinetic energy and hence the speed of the two stones should also be same in order for the mechanical energy to remain conserved.
Answer: 5billion years
Explanation: The sun produces energy through radioactive fusion reaction.
Nebula theory states that the gaseous particles of the Earth collapsed as a result of its own gravity which continuously lead to fusion reaction for the production of nuclear energy.
The Core of the Sun is that area up to 25% from the radius of the sun,here the pressure here range up to 250million atmosphere containing mainly hydrogen which gets converted in Helium molecule. The core is the center for energy production accounting for more than 98%, nuclear energy is transmitted at about 4.3million metric tons per second.
Answer:
z = 93.2 m
Explanation:
We can appreciate that this expression is equivalent to the linear motion equation with constant acceleration
v² = v₀² + 2 a d
If we make a term-to-term comparison with the expression obtained, they are equivalent
u² = v² + 2 a z
From here we can clear the position
2 a z = u² –v²
z = (u² –v²) / 2 a
Let's calculate
For the speed to reduce the acceleration must be negative
z = (0 - 21.8²) / 2(- 2.55)
z = 93.2 m
