Answer:
the weight of the object decreases when it is taken from the Earth to the Moon
Explanation:
The weight of an object is defined as the product of the mass of the object with the acceleration due to gravity of the Planet.
where,
W = weight of the object
m = mass of the object
g = acceleration due to gravity on the planet
The mass of an object remains constant everywhere in the universe. Therefore, the weight is directly proportional to the value of acceleration due to gravity.
The value of acceleration due to gravity on the Moon is lesser than its value on the Earth.
<u>Hence, the weight of the object decreases when it is taken from the Earth to the Moon </u>
I think that the answer is c. good luck
Explanation:
The given data is as follows.
Mass of small bucket (m) = 4 kg
Mass of big bucket (M) = 12 kg
Initial velocity () = 0 m/s
Final velocity () = ?
Height = 2 m
and, = 0 m
Now, according to the law of conservation of energy
starting conditions = final conditions
235.44 = + 78.48
= 4.43 m/s
Thus, we can conclude that the speed with which this bucket strikes the floor is 4.43 m/s.
If the amount of electrical energy is 50 Joules before the conversions, then it would be 50 Joules after the conversion.
According to law of conservation of energy, we cannot create or destroy energy so it remains constant
Hope this helps!
Inertia. The moon, the Earth, and everything else in the universe has gravity. The difference is inertia. Think of inertia as constant movement, like a hockey puck sliding across the ice. The puck will go in a straight line until another force acts upon it. Now imagine that you hit that hockey puck so hard that it goes fast enough to achieve orbit around the Earth. What is happening to the puck in this case, is that while the puck is going extremely fast, it is also falling towards the Earth. The thing is that the surface of the Earth is curved, so that the puck falls towards the Earth at a rate equal to the curvature of the Earth. The puck then can never hit the Earth as long as it continues at this speed; as long as its INERTIA remains constant. The same is true for the Moon. The Moon is actually falling towards the Earth, but it is going so fast that the rate at which it falls to the Earth is proportional to the curve of its orbit around the Earth. It is helpful to imagine that everything in the universe is moving, all the time.
