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:
17.66 kPa
Explanation:
The volume of water in the swimming pool is the product of its dimensions
V = 30 * 8.7 * 1.8 = 469.8 cubic meters
Let water density , and g = 9.81 m/s2 we can calculate the total weight of water in the swimming pool
The area of the bottom
A = 30 * 8.7 = 261 square meters
Therefore the pressure is its force over unit area
or 17.66 kPa
