Answer:
what do you mean ???????????
Answer:
1.) strength or energy to do an action or movement
2.)an object will jot change its motion unless acted on by an unbalanced force
Answer:
F = 400 N
Explanation:
Given,
The acceleration of the car, a = 8 m/s²
The mass of the passenger, m = 50 Kg
The force acting on a body is equal to the product of the mass and its acceleration
F = m x a newtons
Substituting the given values in the above equation,
F = 50 Kg x 8 m/s²
= 400 N
Hence, the force exerted by the person on the seat belt is, F = 400 N
Metal atoms move freely. The metallic bond is the force of attraction between the free electrons and metal ions. Metallic bonds are strong so metals can keep a regular structure and usually have strong melting and boiling points.

Explanation:
Hydrostatic pressure is the pressure exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity. Hydrostatic pressure increases in proportion to depth measured from the surface because of the increasing weight of fluid exerting downward force from above.
The formula is :
P= d x g x h
p: hydrostatic pressure (N/m²)
d: density (kg/m³) density of seawater is 1,030 kg/m³
g: gravity (m/s²) ≅ 9.8m/s²
h: height (m)
