The electrical free path of electron is disturbed with vibrations not normal to normal / room temperature  because the electrical heater is agitating the conductor material. this causes the electrons to vibrate more creating more resistance to the flow.

A 3.00 kg ball is dropped from the roof of a building 176.4 m high. While the ball is falling to Earth, a horizontal wind exerts
Katen [24]

Answer:

a.)How far from the building does the ball hit the ground?

72 m

b.)How long does it take to hit the ground?

6 s

c.)What is its speed when it hits the ground?

63.48 m/s

Explanation:

When an object is in free fall with no air resistance present or wind acting on it it only is under the influence of gravity. Gravity acts straight down and accelerates the object all the way to the ground. If there is air resistance or a wind force on the object it will have an acceleration that isn't 9.8 m/s^2

A group of air particles in a balloon are spread far apart and moving rapidly around inside the balloon. The balloon is placed i
Slav-nsk [51]

Answer:

1) The balloon will shrink

2) The balloon will grow bigger and regain its shape

Explanation:

By the kinetic theory of gases, we have;

v_{rms} = \sqrt{\dfrac{3 \cdot R \cdot T}{MW} }

P = \dfrac{n \cdot MW \cdot vrms^2}{3 \cdot V}

Where;

v_{rms} = RMS Speed

R = The universal gas constant

T = The temperature

MW = The Molecular weight

n = The number of moles

V = The volume

P = The pressure

1) When the balloon is placed in the refrigerator for  minutes, the temperature inside the balloon will drop and RMS speed will reduce, however due to the elastic wall of the balloon, the pressure will remain the same therefore the volume  will reduce and the balloon will shrink

2) When the balloon is placed on the kitchen counter, the temperature inside the balloon will rise leading to the increase in the RMS speed which will raise the pressure effect on the wall  of the balloon as the balloon is made of elastic material, as the pressure rises, the wall expands to keep the pressure constant and the volume occupied by the air particles will increase, the balloon will grow bigger and regain its shape.
