Answer:
Newton's third law of motion
Explanation:
Newton's third law of motion: every action has an equal and opposite reaction. Nikolas is using the compressed carbon dioxide to push him on his skateboard. Once the gas is released, it applies force that'll push him in the opposite direction, forward.
We assume
(acceleration is constant. We apply the equation
where s is the distance to stop
. We find the acceleration from this equation
We know the acceleration, thus we find the distance necesssary to stop when initial speed is
When a magnet is moved into a coil of wire, changing the magnetic field and magnetic flux through the coil, a voltage will be generated in the coil according to Faraday's Law.
Answer:
They create electricity from the sun's rays
Explanation:
By the use of "solar cells" or "solar panel", you can trap solar energy in silicon/germanium rods, then you can convert in into electricity too. Solar powered panels convert the sun's rays into electricity by exciting electrons in silicon cells using the photons of light from the sun. This electricity can then be used to supply renewable energy to your home or business.
Answer:
60m/s
Explanation:
since the object is falling under the influence of gravity, the formula is
v = u +gt
before the fall, the object is at rest then
u = 0m/s
v = 0 + 10×6 because acceleration due to gravity is g which is given as 10m/s2
therefore, v = 60m/s
