A rock is stuck deep in the dirt. When you pull on the rock to remove it, what type of force are you exerting?

Physics

It is Tension as the other 3 answer choices would not make sense. Compression would mean you are pressing the rock on both sides or in this case, pushing it into the dirt. It can't be nuclear force as you are pulling out a rock. Air resistance would not make sense either as there is no air involved in the scenario at all.

Answer:

C). Tension Force

Explanation:

As we know that the different forces will act at different situations

A) Compression : here when compression occurs then the force is applied along the length of the object due to which its length will contract and it will apply force linearly.

B) Strong Nuclear Force : This only occurs are nuclear level when nuclei comes closer to each other then only this force will exert and it will be the strongest force.

C). Tension : This force will occur when we pull an object and there is no change in the length of the object. So tension force will be the force when there is a pull.

D) Air resistance : this force is due to opposite force of air molecules due to which it resist the motion of object

What is the kinetic energy of a bike with a mass of 24 kg traveling at 3 m/s?
erastovalidia [21]

Answer:

KE = 1/2mv^2

KE = 1/2(24)(3^2)

KE = 12(9)

KE = 108 J

According to the law of reflection, the angle of incidence is equal to the angle of
Darina [25.2K]

Before going to answer this question first we have to understand reflection and laws of reflection.

Reflection is the optical phenomenon in which light will bounce back to the same medium from which it had originated .

Whenever a light ray will incident on a mirror or any reflecting surface, it will be reflected. The ray which falls on the reflecting surface is called incident ray and the ray which is reflected is called reflected ray.

Let us consider a normal to the point of incidence.The angle made by incident ray with the normal is called angle of incidence.Let it be denoted as[ i ]

The angle made by the reflected ray with the normal is called angle of incidence.Let it be denoted as [r]

There are two types of reflection.One is called regular and other one is called as irregular.The laws of reflection is valid for both the types of reflection.

There are two laws of reflection.

FIRST LAW -It states that the incident ray,reflected ray and the normal to the point of incidence,all lie in one plane.

SECOND LAW- It states that that the angle of incidence is equal to the angle of reflection irrespective of the type of reflection.i.e i =r

Hence the correct answer will be angle of reflection.
