Answer:
A) A buoy rises in the water as a boat speeds past.
Explanation:
The passing boat transfers energy in the form of a wave. Other options illustrate other physics concepts like gravity (falling egg) or Newton's law (for every action, there is an equal and opposite reaction).
I believe the answer would be mass. Low mass stars and medium mass stars often become white dwarfs when they die while high mass stars explode in violent explosions called supernovas and usually leave behind a black hole or a neutron star.
Answer:
Explanation:
The force acting on the electron due to the magnetic field is
where
is the charge of the electron
is its speed
is the intensity of the magnetic field
is the angle between the direction of the field and the velocity of the electron
Substituting all the numbers into the equation, we find
Answer: When the box is on a step and in a resting position then in this situation, the forces acting on the box is said to be balanced forces. While carrying the box to the top of the stair then the forces acting on it will be unbalanced forces.
Explanation:
When the box is on a step and in a resting position then the forces acting on the box are acting in an equal in magnitude and opposite in direction. Therefore, these forces are balanced forces.
While carrying the box to the top of the stair then the forces acting on it will be unbalanced forces because the box is changing its state. There is an unbalanced force which opposes the motion of the box.
