what is the light that appears when you touch something metal while you have alot of static electricity

1 answer:

When you touch a doorknob (or something else made of metal), which has a positive charge with few electrons, the extra electrons want to jump from you to the knob. That tiny shock you feel is a result of the quick movement of these electrons.

Noelle walks from point A to point B at an average speed of 5 kilometers per hour. At what speed, in kilometers per hour, must N

Debora [2.8K]

Answer:

the speed at which Noelle walks from point B to A, v=7.5 kilometers per hour

Explanation:

In this question we have given

average speed for the entire trip,S = 6 kilometers per hour

Speed of Noelle while walks from point A to B= 5 kilometers per hour

Therefore, time taken by Noelle to walks from point A to B, $t_{1}=\frac{d}{5}$

Let us consider distance between A and B is d.

Therefore total distance covered in moving from point A to B and then moving back from point B to A, = $d+d=2d$

Let v be the speed at which Noelle walks from point B to A

Therefore time taken by Noelle to walks from point B to A, $t_{2}=\frac{d}{v}$

we know that average speed S is given as

$S=\frac{x}{t}$ ................(1)

here, x (=2d) is total distance

and t (= $t_{1}+t_{2}$ ) is total time

put values of S, x and t in equation 1

$6 =\frac{2d}{\frac{d}{5}+\frac{d}{v} }$

on solving we get,

v = 7.5 kilometers per hour

Therefore, the speed at which Noelle walks from point B to A, v=7.5 kilometers per hour

HELPPPP PLS ASAP

Lena [83]

Answer:

Part A: The car shoots out of the milk carton at a fast speed.

Part B: Potential Energy

Part C:

1. Gravitational Potential Energy

2. Motion Energy

3. It goes from Motion Energy/Kinetic Energy to Gravitational Potential Energy.

4. Motion Energy

Part D: It is a transfer of energy from the rubber band to the car.

Part E: The car stopped because of gravitation pull that is slowly making the car slow down and eventually stop. The energy is then converted to kinetic energy and heat energy.

Part F: I would think adding force would make the car move again. The type of energy it would have while moving would be: Motion Energy.

Have a great day! :D

The tires of a car support the weight of a stationary car. If one tire has a slow leak, the air pressure within the tire will __

mrs_skeptik [129]

Answer:

The answer is E. Decrease, increase, decrease

Explanation:

The pressure within the tire wall is a result of the molecules of air colliding with the walls of the tire, if there is a leakage that means some or all of the air molecules will escape resulting in a decrease in the collision between the molecules and the tire wall which means the pressure decreases within the walls which also translates to a decrease in pressure exerted by the tire on the ground surface.

Before the leakage, the tire walls are kept tensed due to the internal pressure exerted by the air molecules. When the leakage occurs the air molecules escape and this makes the tire loose its firm upright shape thereby falling to the floor and creating an increase in the area of contact between the tire and the floor surface.

The force exerted on the floor by the tire is proportional to the the pressure exerted and the surface area through which this force is applied, though the pressure is seen to decrease and the surface area seen to increase, one must consider the weight loss due to the air molecules that escapes which causes the force to decrease.
