Field force have property to act at certain range of distance

It will act upto a certain range of distance

Here we can say that the magnetic property that best describes the magnet's ability to act at a distance is given by

Magnets have magnetic fields.

Answer: The correct answer is "Magnets have magnetic fields".

Explanation:

Magnet has two poles: South pole and North pole. Same poles of the magnet repel each other. The opposite poles of the magnet attract each other. There is strong magnetic force of repulsion between the same poles of the magnet. There is strong magnetic force of attraction between the opposite poles of the magnet.

Magnetic field lines: These field lines are the area around the magnet in which the magnetic force can be experienced.

The magnetic field is stronger at the ends. The strength of the magnetic field decreases with the distance from the poles.

Therefore, from the given options, "magnets have magnetic field" which best describes a magnet's ability to act at a distance.

A large box of mass M is pulled across a horizontal, frictionless surface by a horizontal rope with tension T. A small box of ma
Nesterboy [21]

Answer:

T = g μ_s ( M+m )

78.4 N

Explanation:

When both of them move with the same acceleration , small box will not slip over the bigger one. When we apply force on the lower box, it starts moving with respect to lower box. So a frictional force arises on the lower box which helps it too to go ahead . The maximum value that this force can attain is mg μ_s . As a reaction of this force, another force acts on the lower box in opposite direction .

Net force on the lower box

= T - mg μ_s = M a    ( a is the acceleration created by net force in M )

Considering force on the upper box

mg μ_s = ma

a = g μ_s

Put this value of a in the equation above

T - m gμ_s = M g μ_s

T = mg μ_s + M g μ_s

=  g μ_s ( M+m )

2 )

Largest tension required

T = 9.8 x  .50 x ( 10+6 )

= 78.4 N

A rotating beacon is located 2 miles out in the water. Let A be the point on the shore that is closest to the beacon. As the bea
Mice21 [21]

Answer:

v = 3369.2 m/s

Explanation:

As we know that Beacon is rotating with angular speed

f = 10 rev/min

so we have

\omega = 2\pi f

\omega = 2\pi(\frac{10}{60})

\omega = 1.047 rad/s

now we know that

v = r \omega

here we will have

r = 2 miles = 2(1609 m)

r = 3218 m

so we have

v = 3218(1.047)

v = 3369.2 m/s
