Answer:
I didn't know these questions sorry
Explanation:
The power P dissipated by a heater is defined as
where V is the voltage and I is the current.
a) The current running through a 130-W heater is
b) The resistance <em>R</em><em> </em>of the heater is
where 
is our familiar Ohm's Law.
Answer:
Gravity, normal force, friction, and air resistance.
Explanation:
Assuming the ball is on earth, there is always gravity acted upon the object.
Since the problem said that the golf ball is moving throughout the air, we can tell that there will be air resistance and friction(air resistance is a type of friction). There is also normal force pushing on the ball as it bumps into the air, as the air is pushing back with an equal and opposite force.
I don't know what you mean by "applied", so I don't think there's that type of force exerted on the ball.
Lastly, tension only occurs when you pull a string/rope. There is no string/rope in this case, so there is no tension exerted on the ball.
I hope this helped you.
