Answer:

D. location

Explanation:

The gravitational field strength of Earth is determined by the virtue of the location within the Earth's gravitational field.

That's why all objects regardless of their mass, shape, and size free fall towards the Earth with an acceleration equal to the acceleration at that location in the absence of air resistance.

According to the gravitational force between two bodies, the force experienced by one body due to the other is independent of its own mass.

The gravitational force is given by equation

                                  F =  GMm/r²

If F is the force acting on the smaller body of mass 'm', then

                                 F = ma

Therefore, the equation becomes,

                                ma = GMm/r²

                                   a = GM/r²

The value of 'a' changes with respect to the value of 'r' such that if 'r' is the radius of the Earth, then the acceleration at a height 'h' from Earth surface is given by

                                 a = GM/(r+h)²

Here it is clear that the acceleration at any point is only the inherent property of the Earth itself.

The gravitational field strength of Earth is determined by the virtue of the location within the Earth's gravitational field.

Air trapped in the cooling system could create undesirable areas of combustion heat buildup in the engine called _____.
viktelen [127]

Answer:

<em>Air pockets.</em>

<em></em>

Explanation:

Air pockets in the cooling system are bubbles of air trapped within the lines (hoses and pipes) of the cooling system. This air bubbles enter the cooling system usually during the process of filling the radiator coolant fluid (usually water), or replacing the water pump or the radiator hose during repairs or servicing of the cooling system. <em>The trapped air prevent pressure movement that is needed by the coolant to move the heat generated from the engine cylinder, resulting in heat build up</em>. The solution is to "bleed" the engine through the radiator lid or some air release valves.

An ice skater is gliding horizontally across the ice with an initial velocity of 7.56 m/s. The coefficient of kinetic friction b
Lunna [17]

Answer:  7.723s

Explanation:

given data:

initial velocity = 7.56 m/s.

friction = 0.0695.

change in velocity = 2.32 m/s

<u><em>Solution:</em></u>

ax = \frac{-Fk}{m}

ax = \frac{-ukFN}{m}

ax = \frac{-ukmg}{m}

ax = -ukg

recall = v0x +axt.......eqn1

t = \frac{vx - v0x}{ax} ........eqn2

substitute  ax  into  eqn 2

t = \frac{vx -v0x}{-ukg}

t = \frac{2.32m/s - 7.56m/s}{-(0.0695)(9.80m/s^{2})}

t=  7.723seconds
