Answer:

The hairs would have acquired charge by the passing of dry winds resulting in the loss of electron.

Explanation:

While standing on the top of a mountain if a person gets its hairs stand up after a cloud passes over, this might happen due to the static electric charges on the lower surface of the cloud  are opposite in nature to that of hairs which the hairs would have acquired by the passing of dry winds which would have resulted in the loss of electron from the hair tip.

Similar case happens when we rub a dry plastic ruler or a dry plastic comb on our hairs.

How much time does it take for a car traveling at 65 miles/hour to travel 300 miles
galina1969 [7]

Time taken by the car to travel 300 miles is 4.615 hours.

<h3>What is speed?</h3>

The speed of any moving object is the ratio of the distance traveled and the time taken to cover that distance.

Given is the distance d = 300 miles and the speed s = 65 miles/hour, then the time taken t will be

s=d/t

65 = 300/t

t= 4.615 hours

Thus, time taken by the car to travel 300 miles is 4.615 hours.

A force acts on a 5kg object at rest. How fast will the object accelerate on a frictionless surface?
MakcuM [25]

Answer: The answer is C.) 25 m/s^2.

Explanation: If you input 5 as s, you would have to use the exponent 2.  This means that you have to multiply 5 by 5.  5 x 5= 25.  

Edit: Also, because the surface is frictionless, it will make the object go faster too.  Nothing can really slow it down unless something blocks it.
