Answer:

c. Each half becomes a new bar magnet with two magnetic poles.

Explanation:

As we know that each magnet must have two opposite poles at its two ends

1. North Pole

2. South pole

now we defined magnetic moment of the magnet as product of pole strength of magnet with its length.

Here as we brake a magnet into two pieces then each part of the magnet will again develop poles on two parts and each part will behave like a new magnet in which we will have two poles.

but in this case the magnetic moment of the magnet will change due to change in the length

Here magnetic pole strength will not change as it will not depends on the length of magnet

C. Each half becomes a new bar magnet with two magnetic poles.

A magnet is still a magnet, no matter how many pieces it is in.

1. In which direction can a force be exerted on an object?

My name is Ann [436]

A. Any Direction
This should be obvious, as you can push down on something, push it to the sides, and push something up. Hope this helped!

A jet plane comes in for a downward dive as shown in the figure below.

xxTIMURxx [149]

The solution would be like this for this specific problem:

5.5 g = g + v^2/r 
4.5 g = v^2/r 
v^2 = 4.5 g * r 
v = sqrt ( 4.5 *9.81m/s^2 * 350 m) 
v = 124 m/s

So the pilot will black out for this dive at 124 m/s. I am hoping that these answers have satisfied your query and it will be able to help you in your endeavors, and if you would like, feel free to ask another question.

A point charge of -2 µC is located at the origin. A second point charge of 6 µC is at x = 1 m, y = 0.5 m. Find the x and y coord

Soloha48 [4]

Answer:

x coordinate = -1.66 m

y coordinate is = -0.825m

Explanation:

Suppose z be the distance form the first charge and z + sqrt(1^2 +.5^2) be the distance from the second So z + sqrt(1+.25) = z + 1.12

We have k*2.0x10^-6/s^2 = k*6x10^-6/(s+1.12)^2

0.0356s^2 -0.019s-0.0897=0

s=1.876m

The angle of the line between the two charges is arctan(.5/1) = 26.6o

x coordinate = -1.876*cos(26.6) = -1.66m

y coordinate is -1.876*sin(26.6) = -0.825m

How many neutrons is there in that element that has 36 protons and 36 electrons

bagirrra123 [75]

You need to know the mass number to work it out. I can see you have it but it's not visible on your photo.

Every proton weighs 1 and every neutron weighs 1 so if you know the total mass of the nucleus and the number of protons, then you can do:
Mass Number - Proton Number = Neutron Number
because the rest of the mass (that isn't from the protons) must come from the neutrons. Make sense?

A 60kg student traveling in a 1000kg car with a constant velocity has a kinetic energy of 1.2 x 10^4 J. What is the speedometer

777dan777 [17]

Answer:

17.64 km/h

Explanation:

mass of car, m = 1000 kg

Kinetic energy of car, K = 1.2 x 10^4 J

Let the speed of car is v.

Use the formula for kinetic energy.

$K = \frac{1}{2}mv^{2}$

By substituting the values

$1.2\times 10^{4} = \frac{1}{2}\times 1000\times v^{2}$

v = 4.9 m/s

Now convert metre per second into km / h

We know that

1 km = 1000 m

1 h = 3600 second

So, $v = \left (\frac{4.9}{1000} \right )\times \left ( \frac{3600}{1} \right )$

v = 17.64 km/h

Thus, the reading of speedometer is 17.64 km/h.
