What are the two factors on which the force of friction depends? 9. Suppose a bell is ringing in a vacuum. Will you able to hear the sound?​

Answer 1

Answer:

Hey mate this is ur answer

Explanation:

The pressure tells us how much force acts in unit of area. In this case, an area of 2mm

2

is applied with a force of 2 N.

Pressure is calculated as follows.

Pressure=

area

Force

=

2mm

2

2N

=1N/mm

.

Hence, the pressure on the object is

1N/mm

2

=10

6

N/m.
