The magnetic field is strong near the ____ of a magnet.

1 answer:

3 0

The magnetic fields of magnets are most powerful at the <u>poles of a magnet</u>. Without any difference in the magnitude, both the poles have equal amount of Magnetic field intensity at their poles.

If you see the field lines we can see the field lines start from the North Pole run parallel and end at the South Pole. The field lines are concentrated more at the poles hence the magnetic field intensity or the magnetic field itself is more at the poles than any other part.

A plastic box has an initial volume of 2.00 m 3 . It is then submerged below the surface of a liquid and its volume decreases to

Answer:

Volume strain is 0.02

Explanation:

Volume strain is defined as the change in volume to the original volume.

It is given that,

Initial volume of the plastic box is 2 m³

It is then submerged below the surface of a liquid and its volume decreases to 1.96 m³

We need to find the volume strain on the box. It is defined as the change in volume divided by the original volume. So,

$\delta V=\dfrac{V_f-V_i}{V_i}\\\\\delta V=\dfrac{1.96-2}{2}\\\\\delta V=0.02$

So, the volume strain on the box is 0.02.

The watermelon is heaviest, followed by the soccer ball, golf ball and ping pong ball. How does the weight of an object relate t

Illusion [34]

Answer:

It doesn’t really relate

Explanation:

heavier load the parachute must be moving faster to match the downward force of the greater load

and approx terminal velocity when the parachute is open

velocity for Ping pong ball with parachute = 9m/s

velocity for Soccer ball with parachute = 15m/s

velocity for Golf ball with parachute =24m/s

velocity for Watermelon with parachute = 25m/s

so weight of an object doesn’t really realted how fast it falls with a parachute
