Answer:
Explanation:
The gravitational field strength at a point is the gravitational force exerted per unit mass placed at that point. This means that the gravitational field strength, g {\displaystyle g} is equal to the force experienced by a mass of 1 kg in that gravitational field.
A.
self-actualization
B.
esteem
C.
safety
D.
physiological
Answer:
Tides are the rise and fall of sea levels. Tides occur due to the gravitational forces exerted on the Earth by moon, and to a lesser extent, the sun. That's why tides occur in ocean or sea.

Answer:
Fever or elevated body temperature might be caused by:
A virus.
A bacterial infection.
Heat exhaustion.
Certain inflammatory conditions such as rheumatoid arthritis — inflammation of the lining of your joints (synovium)
A malignant tumor.
Many illness-causing microbes do best at the body's normal temperature. A fever raises the temperature beyond which certain microbes need to reproduce. A fever also kicks your child's immune system into high gear, spurring the rapid production of bug-clobbering white blood cells.

Given data
mass (m) = 13 kg
F₁ = 13 × 9.8 = 127.4 N
air resistance (F₂ ) = 9 N, acts in opposite direction
Net force is defined as sum of all forces
Fnet = F₁ - F₂
= 127.4 - 9
= 118.4 N
Net force acting on the object is 118.4 N
