Why does time seem to flow only in one direction? What happens in the gray zone between solid and liquid? Can we find a unified theory of physics?
Answer:
Molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. Molecules must collide with the proper orientation.
Explanation:
A collision that meets these two criteria, and that results in a chemical reaction, is known as a successful collision or an effective collision.
Answer:
pressure = force ie 500 N divided by area ie 0.05m².
p=f by a
p= 500n divided by 0.05 m²
p= 10,000 pascal

Since the initial and the final velocity are just equal, it is implied that the acceleration is zero. This means that the net force acting on the body is also zero. The horizontal force should be equal to the force of friction. The force of friction is equal to the product of the coefficient and the normal force.
Ff = (coefficient of friction) x Fn
The normal force is equal to the object's weight if the surface is horizontal.
Ff = (0.20) x (30 kg) x (9.8 m/s²) = 58.8 N

<span>Thus, the horizontal force exerted must be 58.8 N.
