Acceleration of the ball is
Explanation:
The acceleration of the ball can be found by using Newton's second law of motion, which states that the net force acting on an object is equal to the product between the mass of the object and its acceleration:
where
F is the net force
m is the mass
a is the acceleration
For the ball in this problem, we have
m = 0.50 kg (mass)
F = 25 N (force)
thereofre, the acceleration of the ball is

The kinetic energy of the car is
Explanation:
The kinetic energy of an object is the energy possessed by the object due to its motion.
Mathematically, the kinetic energy is
where
m is the mass of the object
v is its speed
For the car in this problem,
m = 740 kg
v = 33.5 m/s
Therefore, the kinetic energy of the car is

How a Inkjet printer uses electrical charges and tiny particles to print the image is discussed below.
We have a Inkjet printer which uses electrical charges and heat to fuse tiny plastic particles (called toner) to the paper.
<h3>What are Electrical Charges?</h3>
The sufficiency or deficiency of electrons in a body leads to the development of electric charge in a body. Its unit is Coulomb. It can be either Positive or Negative in nature.
According to the question -
The statement mentioned in the question is true. The inkjet printers use electrical charges and heat to fuse tiny plastic particles (called toner) to the paper. Printers attract toner particles (with the help of electric charge) to a transfer roller. Toner particles are pressed onto a piece of paper, while heat and pressure from the fuser unit permanently fix the image onto the page.

Because temperature indicates the movement of heat, which means that thermal energy is temperature.
Black holes.
Although black holes don't have surface they are the only known object that has gravity that not even light can escape it.
