What is th weight on earth of a girl with a mass of 30 kg?
Use the formula
W = M g
g is the acceleration of gravity, 9.8 m/s^2.
To calculate the weight of an object on Earth, you can use the formula:
Weight = Mass x Acceleration due to Gravity
On Earth, the acceleration due to gravity is approximately 9.8 m/s^2.
So, to find the weight of a girl with a mass of 30 kg on Earth, you can do the following calculation:
Weight = Mass x Acceleration due to Gravity
Weight = 30 kg x 9.8 m/s^2
Weight = 294 N
Therefore, the weight of a girl with a mass of 30 kg on Earth is approximately 294 Newtons.
