The electric field of a charge is defined by the force on: An electron A probe charge A proton. A source charge.

Alina [70]

Answer:

A probe charge

Explanation:

As we know that electric field intensity is the force experienced by the probe charge which is placed in the electric field region

Here we can say it as

$E = \frac{F}{q}$

so here that probe charge should be very small so that it will not disturb the electric field in the space.

If the probe charge is of large magnitude then the field will get disturbed and the intensity which is to be measured is different from its actual value.

Also the sign of the probe charge is taken to be positive.

so correct answer here will be

A probe charge

Your roommate is working on his bicycle and has the bike upside down. He spins the 68.0 cm -diameter wheel, and you notice that

MAVERICK [17]

Answer:

a. 6.41 m/s

b. 120.85 m/s^2

Explanation:

The computation is shown below:

a. Pebble speed is

As we know that according to the tangential speed,

$v = r \times \omega$

$= \frac{0.68}{2} \times 18.84$

= 6.41 m/s

The 18.84 come from

$= 2 \times 3.14 \times 3$

= 18.84

b. The pebble acceleration is

$a = \frac{v^2}{r}$

$= \frac{6.41^2}{0.34}$

= 120.85 m/s^2

We simply applied the above formulas so that the pebble speed and the pebble acceleration could come and the same is to be considered

Please assist with solving this problem and showing the steps

Lapatulllka [165]

Answer:

2.21 N

Explanation:

The force in this case is the total mass multiplied by the acceleration due to gravity. You are not asked for the solution to be in terms of the torque which is the usual way to solve these problems. That's why you are not given where the fulcrum is.

The fulcrum feels F1 + F2 + 34 * 980

F2 = 141.7 * 980 = 138866

F1 = 50.3 * 980 = 49294

Ruler = 34 * 980= 33320

Total Force = 221480 The units here are dynes

I just saw in the middle of the question that g = 9.80

So the answer becomes 221480 / 1000 = 221.48 because we needed kg

And that answer becomes 221.48/100 2.21 because the force of gravity should be 9.8 not 980

The total force exerted on the fulcrum is

A substance can be classified by its physical properties which are properties that

irakobra [83]

Hello :)
Physical properties are properties that you can see, feel and measure, they do not change the matter of the substance. Some examples of physical properties are Mass, Color, Shape, Hardness and Boiling point.
