Answer:
Pressure is defined as the force divided by the area perpendicular to the force over which the force is applied, or. P=FA. A given force can have a significantly different effect depending on the area over which the force is exerted Pressure the effect of a force applied to a surface is a derived unit, obtained from combining base units. The unit of pressure in the SI system is the pascal (Pa), defined as a force of one Newton per square meter. The conversion between atm, Pa, and torr is as follows: 1 atm = 101325 Pa = 760 torr.
Explanation:
Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A. Because pressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m2. If you convert an atmosphere to pounds per square inch, it's about 14.7 psi.
Explanation:
Given that,
Force with which a child hits a ball is 350 N
Time of contact is 0.12 s
We need to find the impulse received by the ball. The impulse delivered is given by :
So, the impulse is 42 N-m..
We know that he change in momentum is also equal to the impulse delivered.
So, impulse = 42 N-m and change in momentum =42 N-m.
To make something electrical you need electricity and the wires will turn a magnet into an electromagnet.
