Answer:
Weight of body = 490 Newton
Explanation:
Mass of the body is the total amount of matter contained in the body but Weight of the body is the force exerted by gravity on the body. Weight of the body depends upon acceleration due to gravity of the planet.
Thus,
Weight = mass × acceleration due to gravity
W = mg
W = weight of the body
m = mass of the body
g = acceleration due to gravity
W = 50 × 9.8
W = 490
W = 490 Newton
Hence, weight of the body is 490 Newton.
Answer:
The force exerted on a given area.
Option B is the right option.
Explanation:
<h2><u>About</u><u> </u><u>pressure</u></h2>Pressure is defined as force acting per unit area. It's SI unit is Pascal or N/m^2.
Formula to find pressure is:
The force acting perpendicular on a surface is called the <u>thrust</u><u>.</u> It is a vector quantity.
<u>One </u><u>Pascal </u><u>pressure</u>
One Pascal pressure is defined as the pressure exerted in a surface of area m^2 by the thrust of 1 N
Hope this helps ..
Good luck on your assignment.....
