I think it will reduce in speed because friction drags it to the opposite direction and it were the girls mass that was overcoming friction but i think it is newtons 2nd law of motion
Answer:
Salt crystals are hard and brittle because they are made up of atoms that combine by ionic bonding.
Explanation:
<span>These elements are what make up minerals. The two most common elements are Oxygen (O) at 47% and Silicon (Si) at 28%. Other common elements are Aluminium (Al) at 8%, Iron (Fe) at 5%, Calcium (Ca) at 3.5%, Sodium (Na) at 3%, Potassium (K) at 2.5% and Magnesium (Mg) at just 2%.

Answer:
A. 88,200 J
Explanation:
Given data,
The mass of the crate, m = 200 kg
The height of the shipping container, h = 45 m
The gravitational of a body is possessed by the body due to the virtue of its position.
The formula for gravitational potential energy is,
P.E = mgh joules
Substituting the values
P.E = 200 x 9.8 x 45
= 88,200 J
Hence, the gravitational potential energy of the crate is, P.E = 88,200 J
