Q=l^2 times R times t
Where Q - heat, I -current, R - resistance and t is time
If you increase I twice (and it's squared), than Q gonna went up 4 times (2 squared).
Choose last
In the first law, an object will not change its motion unless a force acts on it. So I think the answer is A. Only objects that are moving.
Answer:
Newton's Third Law of Motion
Explanation:
Newton's Third Law of Motion which states that, for every action there is an equal but opposite reaction.
This ultimately implies that, in every interaction, there is a pair of forces acting on the two interacting objects.
In this scenario, a ball bounced by a basketball player on the floor bounces back up at her.
According to Newton's Third Law of Motion, the statement above simply means that in every interaction, there is a pair of forces acting on the two interacting objects i.e the ball and floor. The size of the force on the ball equals the size of the force on the floor. These two forces are called action and reaction forces and are the subject of Newton's third law of motion.
Hence, the ball bounced by the basketball player on the floor would bounce back in equal magnitude.
Density = mass / volume
D = 89 / 10.0
D = 8.9 g/cm³
hope this helps!
