<h3><u>Answer;</u></h3>

<em>D. a car starting to move after the light changes from red to green</em>

<h3><u>Explanation;</u></h3>
  • <u><em>Static friction</em></u> is a type of friction or a force that is experienced by a body or a substance at rest. Therefore, when a force is applied on a body or an object at rest it opposes the static friction.
  • <em><u>Static friction </u></em>does not have the ability to move an object or induce motion since it is countered by other strong opposite forces. Static friction must be overcome to cause motion of the object.
  • When a <em><u>body or an object is in motion it experiences kinetic friction</u></em>. Therefore, when a body at rest starts to move then the friction changes to kinetic friction.

What is the momentum of a bus that weighs 13,500,000 grams traveling at 65 mph?
Goryan [66]

The momentum of the bus is 3.93\cdot 10^5 kg m/s

Explanation:

The momentum of an object is given by

p=mv

where

m is the mass of the object

v is its velocity

For the bus in this problem, we have

m=13,500,000 g = 13,500 kg is its mass

v=65 mph \cdot \frac{1609 m/mi}{3600 s/h}=29.1 m/s is the velocity, converted into SI units

Substituting into the equation, we find the momentum of the bus:

p=(13,500)(29.1)=3.93\cdot 10^5 kg m/s

A 285-mL flask contains pure helium at a pressure of 750 torr . A second flask with a volume of 455 mL contains pure argon at a
zaharov [31]

Answer:

P_{He}^|=288.85torr

Explanation:

Given data

P_{He}=750 torr\\V_{He}=285mL\\P_{Ar}=732 torr\\V_{Ar}=455 mL

Required

Partial pressure of helium

Solution

First calculate the total volume of gas mixture once the stopcock is opened

So

V_{total}=V_{He}+V_{Ar}\\V_{total}=285mL+455mL\\V_{total}=740mL

As temperature remains constant,by Boyle's Law we calculate the partial pressure of the helium gas

So

P_{He}V_{He}=P_{He}^|V_{total}\\P_{He}^|=\frac{P_{He}V_{He}}{V_{total}}\\P_{He}^|=\frac{750torr*285mL}{740mL}\\  P_{He}^|=288.85torr

<span>this  may help you
As far as the field goes, the two charges opposite each other cancel!
So E = kQ / d² = k * Q / (d/√2)² = 2*k*Q / d² ◄
and since k = 8.99e9N·m²/C²,
E = 1.789e10N·m²/C² * Q / d² </span>

True or false<br> Hydrogen fuel cells generate electricity by combining hydrogen with oxygen.
adoni [48]

Answer:

The answer is: True.

Explanation:

If free electrons or other substances could travel through the electrolyte, they would disrupt the chemical reaction. Whether they combine at anode or cathode, together hydrogen and oxygen form water, which drains from the cell. As long as a fuel cell is supplied with hydrogen and oxygen, it will generate electricity.
