Answer:
electromagnetic wave. this energy is what lights the bulb.
Explanation:
When you close an electrical circuit, the electrons have a small drag speed, but the fluctuation of the electric field that is created originates by Lenz's law a magnetic field and the appearance of this magnetic field creates a fluctuating elective field, these two fields together forms a wave called an electromagnetic wave.
This electromagnetic wave has a speed given by the relation
v = √1 /ε μ
in a vacuum this speed is equal to the speed of light, which is worth 3 10⁸ m/s this very high value so the energy transported by this wave can travel the distance of 10 m in less than 10⁻⁷ s, This energy is what lights the bulb.
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.
Answer:
F = 0
Explanation:
The net force acting on an object is given by the product of mass and acceleration. We know that acceleration is equal to the rate of change of velocity.
Net force,
F = ma
The skier is traveling at a constant velocity, it means there is no change in velocity i.e. acceleration is equal to 0. Hence, the force on her is 0.
To do this you would take 64 and divide it by 4.
64/4= 16.
Your answer is 16.
The correct answer is a blackhole.
A blackhole is the only object in which nothing, not even light can escape.
Hope this helps!
