Zinaida [17]

The electrons making the shock come from the women's body.

<h3>What is Electric shock ?</h3>

When a high voltage current flows through the body, electrical shock results. When someone unintentionally touches an electrical source, this typically occurs. Treatment for both internal and exterior burns may be necessary as part of the aftercare.

The nervous system may be impacted by a shock.

The tissue that makes up nerves presents extremely minimal resistance to the flow of an electric charge. Electric shocks that impact nerves can cause pain, tingling, numbness, weakness, or trouble moving a limb. These effects might disappear with time or remain for good.

How to Prevent from Electrical Shocks –

  • Keep the Appliances Away from Moisture and Water.
  • Never Connect or Disconnect Under Load.
  • Be Careful with Capacitors.
  • Use Insulated Tools.
  • Turn Off the Power.
  • Check for Improper or Faulty Wiring.
  • Fix Extension Cord Problems.

Why is the following situation impossible? A skater glides along a circular path. She defines a certain point on the circle as h
Arturiano [62]

Answer:

A skater glides along a circular path. She defines a certain point on the circle as her origin. Later on, she passes through a point at which the distance she has traveled along the path from the origin is smaller than the magnitude of her displacement vector from the origin.

So here in circular motion of the skater we can see that the total path length of the skater is along the arc of the circle while we can say that displacement is defined as the shortest distance between initial and final position of the object.

So it is not possible in any circle that arc-length is less than the chord joining the two points on the circle

As we know that arc length is given as

L = R\theta

length of chord is given as

L_c = 2Rsin(\frac{\theta}{2})

so here

L > L_c

R\theta > 2R sin(\frac{\theta}{2})

so we have

\frac{\theta}{2} > sin(\frac{\theta}{2})

A 56.6-kg crate rests on a level floor at a shipping dock. The coefficients of static and kinetic friction are 0.517 and 0.260,
kifflom [539]

Answer:

Explanation:

Magnitude of frictional force = μ mg

μ is either static or kinetic friction.

To start the crate moving , static friction is calculated .

a ) To start crate moving , force required = μ mg where μ is coefficient of static friction .

force required =.517 x 56.6  x 9.8 = 286.76  N .

b ) to  slide the crate across the dock at a constant speed , force required

= μ mg where μ is coefficient of kinetic  friction , where μ is kinetic friction

= .26 x 56.6  x 9.8 = 144.21 N .

15. When you cannot stop safely at a yellow traffic light before entering an intersection, ______________. A. stop in the inters
Elan Coil [88]

Answer:  When you cannot stop safely at a yellow traffic light before entering an intersection, enter the intersection carefully and continue across.

Explanation: To find the correct answer, we need to know more about the traffic signal rules.

<h3>What is the traffic signal rules?</h3>
  • Red light- Indicator for the motorists to stop.
  • Green-Signal for safety and word GO.
  • Yellow- This signal let you know that the red signal is about to be displayed.
  • when it's turned on, you can start slowing down to come to a stop in anticipation of red light.
  • when we cannot stop safely at a yellow traffic light before entering an intersection, enter the intersection carefully and continue across.

Thus, we can conclude that, the option C is correct.

What is the root mean square speed of an As4 particle as it is sublimed? (Assume at high temperatures arsenic acts like an ideal
Norma-Jean [14]

Answer: v_{rms} = 273m/s

Explanation: <u>Root</u> <u>Mean</u> <u>Square</u> <u>Speed</u> of an atom or molecule is the speed of a particle in a gas. It is the average speed a particle in a gas can have.

It can be calculated:

\frac{1}{2}mv^{2} = \frac{3}{2} k_{B}T

v^{2} = \frac{3k_{B}T}{m}

v = \sqrt{\frac{3k_{B}T}{m}}

m is mass of one atom or molecule in kg.

An atom of Arsenic sublimes at 614°C. Converting to Kelvin:

T = 614 + 273 = 887K

Molecular mass of As4 is approximately 0.3kg.

m = \frac{0.3}{6.10^{23}}

m=5.10^{-25}kg

Calculating Root mean square speed :

v = \sqrt{\frac{3*1.4.10^{-23}*887}{5.10^{-25}}

v = \sqrt{745.08.10^{2}

v = 273m/s

<u>The root mean square speed of As4 is approximately </u><u>273m/s</u><u>.</u>
