1. This image shows the various forces acting on a block of rock situated on a rock slope. What does arrow 4 represent?
Gelneren [198K]

Answer:

B. Gravitational force

Explanation:

The gravitational force of an object (also called weight) is given by

F=mg

where m is the mass of the object and g is the acceleration of gravity, and it always points in the downward direction.

In this problem, the arrow labelled with 4 is the only force pointing downward: therefore, it must be the gravitational force.

The other arrows represent:

1 --> component of the gravitational force parallel to the plane

2 --> force of friction

3 --> component of the gravitational force perpendicular to the plane

IrinaK [193]

Answer:

Pressure

Explanation:

The measure of how much force is applied to an object from gas particle bouncing into it is called pressure.

Pressure is defined as the force per unit area on a body.

Mathematically;

             Pressure  = \frac{Force}{Area}

The pressure of a gas is the combined force with which gas molecules bombard a unit area of the wall of the container. It is the sum of all tiny pushes on the wall of the container.

Various units of pressure are atm, mmHg, torr, pascal e.t.c
