The average acceleration of car during this time is 5 m/s^2 Northeast.

Answer: Option C

<u>Explanation:</u>

The acceleration exerted by an object is the rate of change in velocity the object undergoes with respect to time. Average acceleration is the measure of variation in acceleration in a given interval of time.

\text {Average acceleration}=\frac{\text {Final velocity - Initial velocity}}{\text {Time Period}}

Here, final velocity is 30 m/s and initial velocity is 10 m/s. The final velocity is attained by the car after 4 s. Thus, the average acceleration will be

\text {Average acceleration}=\frac{30-10}{4}=\frac{20}{4}=5 \frac{\mathrm{m}}{\mathrm{s}^{2}}

So, the average acceleration is 5 m/s^2 and as the car was moving in the northeast direction, the average acceleration will also be exerting in the northeast direction only.

mel-nik [20]

In order to read the publications of his peers, or read his own notes of the work
that he did on the previous day, or find his coffee mug on his desk in the lab, the
research scientist must arrange to have each of them illuminated with visible
wavelengths of light, and then he must catch the light reflected from each of them
with his eyes.

According to the evolutionary perspective of mate selection, why do men and women exhibit different preferences in mate selectio
Alla [95]

C. Each gender has differing attraction cues and priorities.

<h3>Why do men and women exhibit different preferences in mate selection?</h3>

Men and women exhibit different preferences in mate selection because both have different attraction cues and priorities for their partner. These cues and priorities leads to difference in preference of life partner.

So we can conclude that Each gender has differing attraction cues and priorities.

Question 11 (1 point)
Ainat [17]

Answer:

gravitational potential energy.

Explanation:

Gravitational potential energy (GPE) can be defined as an energy possessed by an object or body due to its position above the earth surface.

Mathematically, gravitational potential energy is given by the formula;

G.P.E = mgh

Where,

G.P.E represents gravitational potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

This ultimately implies that, anytime there is height, the object must have gravitational potential energy.

Hence, an object possesses gravitational potential energy due to its height (position) and the earth's gravitational force.
