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?
goodness.
To answer these questions, we need to understand the basic concepts of mass and weight. Mass refers to the amount of matter an object contains and is measured in kilograms (kg). Weight, on the other hand, is the force exerted on an object due to gravity and is measured in units of Newton (N).
1. To find the mass on Earth, you are given that the mass on the other planet is 20 kg. Mass remains constant regardless of the gravitational field, so the mass on Earth will also be 20 kg.
2. To find the weight on Earth, we can use the formula W = mg, where W is the weight, m is the mass, and g is the acceleration due to gravity. On Earth, the acceleration due to gravity is approximately 9.8 m/s^2. Plugging in the values, we get W = 20 kg * 9.8 m/s^2 = 196 N. Therefore, the weight on Earth is 196 Newtons (N).
3. To find the mass on the other planet, you are given that the gravitational constant G on that planet is 2 Newton/kg. Since weight is equal to mass multiplied by the acceleration due to gravity, we can rearrange the formula: W = mg. Dividing both sides of the equation by g, we get m = W/g. Plugging in the values, we get m = 196 N / 2 N/kg = 98 kg. Therefore, the mass on the other planet is 98 kg.
4. To find the weight on the other planet, we can use the formula W = mg. Using the mass on the other planet (98 kg) and the gravitational constant (2 N/kg), we get W = 98 kg * 2 N/kg = 196 N. Therefore, the weight on the other planet is 196 Newtons (N).
