Answer:
8.83m
Explanation:
Given parameters:
Acceleration = 7.8m/s²
Initial velocity = 0m/s
distance covered = 5m
Unknown:
Final velocity = ?
Solution:
The equation to solve this problem with is given as;
V² = U² + 2aS
V is the final velocity
U is the initial velocity
a is the acceleration
S is the distance
Input the parameters and solve;
V² = 0² + 2 x 7.8 x 5 = 78
V = √78 = 8.83m
Answer: well first you have to show or tell us the “error“ Selena made

Answer:
The statement that offers a hypothesis on how people’s backgrounds and interests influence their work is that a person’s background and interests can give him a unique perspective in his research. The correct option is B.
Explanation: Alot of scientist has contributed one way or the other in the model of atoms and this was soo because of their background and interests which gave them a unique perspective in the study of the model of atoms. For example John Dalton who was known to propose the atomic theory, studied chemistry( he had a strong background in knowledge of chemistry) and he had interest in the study of the physical properties of the atmosphere and other gases. This gave him a unique perspective in his research works.
Answer:
a. 150 N
Explanation:
Gravitational Force: This is the force that act on a body under gravity.
The gravitational force always attract every object on or near the earth's surface. The earth therefore, exerts an attractive force on every object on or near it.
The S.I unit of gravitational force is Newton(N).
Mathematically, gravitational force of attraction is expressed as
(i) F = GmM/r² ........................ Equation 1 ( when it involves two object of different masses on the earth)
(ii) F = mg ............................... Equation 2 ( when it involves one mass and the gravitational field).
Given: m = 17 kg, g = 8.8 m/s²
Substituting into equation 2,
F = 17(8.8)
F = 149.6 N
F ≈ 150 N.
Thus the gravitational force = 150 N
The correct option is a. 150 N
