The answer should be C. :)
The change in the skier's gravitational potential energy is 199430 J.
<h3> Gravitational potential energy:</h3>
This is the energy of a body due to its position in a gravitational field. The S.I unit of gravitational potential energy is Joules (J)
The Change in the skier's gravitational potential energy can be calculated using the formula below.
Formula:
- ΔP.E = mg(Δh)............... Equation 1
Where:
- ΔP.E = Change in the skier's potential energy
- m = mass of the skier
- Δh = change in height to which it was raised
- g = acceleration due to gravity.
From the question,
Given:
Substitute these values into equation 1
- ΔP.E = 55×370×9.8
- ΔP.E = 199430 J.
Hence, The change in the skier's gravitational potential energy is 199430 J.

Answer : The correct option is, Number
Explanation :
The periodic table is a type of table in which the element are systematically arranged on the basis of the atomic number.
The periodic table have the groups and periods. In the periodic table, there are 7 horizontal rows of elements are known as period and 18 vertical columns of elements are known as group.
Hence, 1A, 3B, and 7A are examples of group number on the periodic table.
Gene–environment interaction (or genotype–environment interaction or G×E) is when two different genotypes respond to environmental variation in different ways. A norm of reaction is a graph that shows the relationship between genes and environmental factors when phenotypic differences are continuous.
Answer:
Gravitational Force
Explanation:
Gravitational force also called gravity or gravitation is an attractive force that keeps two objects in space. Gravitational force is an attractive force that tends to pull matters together. Every objects in the universe experience gravitational pull. Planets, stars, galaxies, are held together by gravity. It is a weak force. The weight of an object is the product of gravitational force acting on its mass.
Newton's Law of Universal Gravitation states the force of attraction between two masses m₁ and m₂ in the universe is directly proportional to the product of their masses and inversely proportional to the square of their distance apart.
Where;
F is the gravitational force,
G is the gravitational constant = 6.67 × 10¹¹ m³/kg/s,
m1 and m2 are the masses of the objects,
r is the distance between the centers of the masses
