B) gravitational to kinetic
Explanation:
The skydiver, when he is located at a certain height h above the ground, possesses gravitational potential energy, equal to:
where m is the mass of the skydiver, g is the gravitational acceleration and h is the height above the ground. As he falls, its height h decreases, while his speed v increases, so part of the gravitational potential energy is converted into kinetic energy, which is given by
so, we see that as v increases, the kinetic energy increases. Therefore the correct answer is
B) gravitational to kinetic

Answer:
A typical white dwarf is about as massive as the Sun, yet only slightly bigger than the Earth.
Explanation:
A typical white dwarf is about as massive as the Sun, yet only slightly bigger than the Earth.
White dwarfs are one of the densest elements in the universe, surpassed only by neutron stars and black holes. They can be considered as medium mass stars that fuses hydrogen into helium
An epidemiologist is a person who study’s or is an expert in a branch Of medicine the deals with distribution, patterns, and determinants of health and disease conditions. The use of AI would help them to be able to track diseases in growth and degrees on a large scale and in a real time way
Answer:
Option C
Explanation:
Building Restoration, Inc. (BRI) entered into a contact to refurbish an old train depot for Casual Dining which means it will renovate or redecorate the old train depot for casual dining
In case of refurbishing it will just renovate the old building and will not demolish that building
∴ If BRI completes most of the work promised in the contract, its performance will be reformation
