It will possibly be A) chemical b/c it can make a sound like when the bar hits the ball it makes a sound correct?! and also it created heat especially when it hits the ball. and when the ball MOVES and the bar HITS it creates kinetic energy, but when you hit the ball it doesn’t create a new substance.
Answer:
Yes, Centripetal Force acts on the Car.
Explanation:
When a car undergoes a circular motion, a centripetal force acts onto it.
Centripetal Force = [m*(v^2)]/R , where
- R is the radius of curve
- v is the constant speed
- m is the mass of the car
Answer: C. Charge and distance
The acceleration of the box is 
Explanation:
The acceleration of the crate can be found by analyzing the forces acting along the direction parallel to the incline. We have three forces:
- The force of push, F = 125 N, pushing up along the incline
- The force of friction,
, acting down along the incline - The component of the weight parallel to the incline,
, also acting downward
Taking into account the direction of each force, the equation of motion along this direction is:
where
F = 125 N
is the weight of the crate
is the angle of the incline
is the mass of the box
a is the acceleration
And solving for a, we find:

To determine the volume of the aluminum given that it has the same mass as the iron given, we need to divide the mass with the density of aluminum. We calculate as follows:
Volume of aluminum = 70.83 / 2.70 = 26.23 cc
Hope this answers the question. Have a nice day.
