A body of mass 20kg is transferred from earth (grams=weight newton kg) to another planet where G=2 Newton kg,
1.Wat is the mass on earth?
2.wat is the wieght on earth?
3.wat is the mass on the other planet?
4.wat is the weight on the other planet?
I think you meant to write that "g" on the other planet is 2 Newtons PER kg (which is the same as 2 m/s^2). In physics, the capital letter G is reserved for something else.
1. The mass m is always the same
2. weight = m g, where g = 9.8 m/s^2
3. See 1
4. m g', where g' is your "G".
i don't understand cud u make it easier
To answer these questions, we need to first understand the concepts of mass and weight. Mass refers to the amount of matter present in an object and is typically measured in kilograms (kg). Weight, on the other hand, is the force exerted on an object due to gravity and is measured in newtons (N).
1. The mass of the body on Earth is given as 20 kg. This means that the amount of matter in the body is 20 kg, regardless of the presence of gravity or any other external forces.
2. The weight of an object on Earth can be calculated using the formula: weight = mass * gravitational acceleration. On Earth, the gravitational acceleration is approximately 9.8 m/s^2. Therefore, the weight of the body on Earth is:
weight = 20 kg * 9.8 m/s^2 = 196 N
3. To calculate the mass of the body on the other planet, we need to know the weight on that planet. The formula to calculate weight is the same as on Earth: weight = mass * gravitational acceleration. In this case, the gravitational acceleration is given as G = 2 N/kg. Rearranging the formula, we can solve for the mass:
mass = weight / gravitational acceleration = 196 N / 2 N/kg = 98 kg
4. Finally, to find the weight on the other planet, we can use the same formula as before:
weight = mass * gravitational acceleration = 98 kg * 2 N/kg = 196 N
So, the answers to the questions are:
1. The mass on Earth is 20 kg.
2. The weight on Earth is 196 N.
3. The mass on the other planet is 98 kg.
4. The weight on the other planet is 196 N.
