What is the approximate weight of a 20-kg cannonball on earth? 2 n 20 n 196 n 1,960 n

Weight of the cannonball, W = 196 N

Explanation:

Mass of the cannonball, m = 20 kg

We need to find its weight on earth. The weight of an object on the earth can be calculated by the product of mass and acceleration due to gravity as :

W = 196 N

So, the weight of the cannonball on the Earth's surface is 196 N. Hence, this is the required solution.

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
