When the cannonball is shot upwards, kinetic energy converts to gravitational potential energy (GPE).
As the ball rises, speed decreases and height increases.
So when the cannonball has reached its maximum height, all of the Kinetic energy has transferred into gravitational potential energy.
(Because at the max height, the cannonball for a brief moment has no velocity, and thus no kinetic energy)
So the GPE is 48279 Joules at it's maximum height.
An example of using muscular strength would be doing things like lifting weights and things like that.
Answer:
269,000
Explanation:
The distance between Proxima Centauri and the Sun, d₁₁ = 4.246 light years
The distance between Earth and the Sun, d₂ = 1.58 × 10⁻⁵ light years
The ratio of the distances are;
d₁/d₂ = 4.246/(1.58 × 10⁻⁵) = 268734.177215 ≈ 269,000 times
Therefore, Proxima Centauri is approximately 269,000 times further from the Sun than the Earth is from the Sun
Answer:
<h2>
D.)</h2>
Explanation:
Potential energy is when a object is not in motion and the ball is sitting on a shelf not being thrown around or rolling. kinetic energy is when a obeject is in motion and moving.
The "walkie-talkie" is Don Hings' most well-known invention. The earliest versions of this device were designed as portable field radios for the bush pilots of Consolidated Mining and Smeltin , who had to fly their planes between remote sites in the far north of Canada.
