Answer:
A) Increasing, Increasing, Increasing
Explanation:
The greater the rate of fuel ejection higher will be the kinetic energy of the rocket. As rocket is fire upward its fuel rejection rate increases and hence it's kinetic energy increases.
Gravitational potential energy,
as the rocket moves further it's r from the Earth increases. Hence the Gravitational potential energy increases as its height from the Earth increases.
Therefore, mechanical energy of the rocket must also increase as it is sum of kinetic and potential energy.
Hence Option A is correct.
Because we should convert units within the metric system
Answer:
The further the spring is stretched from its origin.
Explanation:
When a spring is stretched or compressed from its original source, a restoring force will act, trying to bring it back to its original state. Hence, Hooke's Law states that the extension of an elastic material is proportional to the load applied or force applied to it. This will continue to hold provided the elastic limit of such material is not exceeded. Therefore, the more it is pull away from the original state, the more restoring force act on it and the more force the that will be needed to pull it away provided the elastic limit is not exceeded.
Answer:
Continuous random variable
Explanation:
The distance that baseball travels after being hit is a random variable and it assume any real value defined on the sample space.
The distance is measurable and thus is continuous random variable because continuous variable cannot be counted but could be measured.
The answer would be D) the building center of a spiral galaxy consisting of stars in the shape of a flattened sphere that circles a black hole
