A charged particle creates a(n) _____________field. Once this particle is in motion, this creates a(n) ____________ field.

Answers

Answer 1
Answer: A charged particle has an electrostatic field surrounding it.

When the particle is in motion, the moving charge is an
electric current, and that has a magnetic field around it.

A rectangular glass block of dimensions 8.0 cm by 15.0 cm by 3.0 cm weighs 10.5 N. Calculate the minimum and the maximum pressure the bock can exert when it rests on a horizontal table.---
Please answer this asap!

Answers

The pressure can be solved using the following formula:

P = mg / A

Where: P = pressure
mg = mass * gravity = W = 10.5 N
A = l*w

Solving for A (maximum):

A = 8*3
A = 24 sq. cm

Solving for A (minimum):

A = 15*8
A = 120 sq. cm

Substituting into the first equation:

Pmax = 10.5 N / 24 sq.cm
Pmax = 0.4375 Pa

Pmin = 10.5 N / 120 sq.cm
Pmin = 0.0875 Pa

If the speedometer on a car indicates a constant speed, can you be sure the car is not accelerating? Explain

Answers

no because it might just have a constant speed , even though it's likely improbable

No,because you can go on an open road then climb a hill and for that you should accelerate for maintain a constant speed

Starting from rest, Christina experiences 24.5 m/s2 of acceleration to take off from an aircraft carrier for 5 seconds. How long does the runway need to be? Round to the nearest meter.

Answers

Answer:

The length of the runway to the nearest meter is 306 m.

Explanation:

Given:

Initial velocity of Christina is, u=0\ m/s(Rest)

Time taken is, t=5\ s

Acceleration experienced by Christina is, a=24.5\ m/s^2

The length of the runway is, d=?

Now, we use Newton's equation of motion that relates the distance, initial velocity, time and acceleration.

So, we have the following equation of motion:

d=ut+(1)/(2)at^2

Plug in all the given values and solve for 'd'. This gives,

d=0+(1)/(2)* 24.5* 5^2\n\nd=(1* 24.5* 25)/(2)\n\nd=(612.5)/(2)\n\nd=306.25\approx 306\ m(\textrm{Rounding to nearest meter})

Therefore, the length of the runway to the nearest meter is 306 m.
