Answer:

Magnetic dipole moment is 0.0683 J/T.

Explanation:

It is given that,

Length of the rod, l = 7.3 cm = 0.073 m

Diameter of the cylinder, d = 1.5 cm = 0.015 m

Magnetization, M=5.3\times 10^3\ A/m

The dipole moment per unit volume is called the magnetization of a magnet. Mathematically, it is given by :

M=\dfrac{\mu}{V}

\mu=M\times \pi r^2\times l

Where

r is the radius of rod, r = 0.0075 m

\mu=5.3\times 10^3\ A/m\times \pi (0.0075)^2\times 0.073\ m

\mu=0.0683\ J/T

So, its magnetic dipole moment is 0.0683 J/T. Hence, this is the required solution.

Answer:

0.068317J/T

Explanation:

Magnetization is defined as the magnetic moment per unit volume means

Magnetization=\frac{Magnetic\ moment}{Volume}

So magnetic moment = magnetization × volume

We have given magnetization = 5.3\times 10^3A/m

Diameter=1.5 cm ,so radius =\frac{1.5}{2}=0.75cm\ =0.0075m

Area A =\pi r^2=3.14\times 0.0075^2=1.766\times 10^{-4}m^2

Length = 7.3 cm =0.073 m

So volume =1.766\times10^{-4}\times 0.073=1.289\times 10^{-5}m^3

Now magnetic moment = magnetization × volume =5.30\times 10^3\times 1.289\times 10^{-5}=0.068317J/T

At a particular instant the magnitude of the gravitational force exerted by a planet on one of its moons is 7 × 1021 N. Collapse
9966 [12]

Answer:

Fg = 4.2*10²² N

Explanation:

The gravitational force between any two masses, provided that can be approximated by point masses (comparing their diameters with the distance between them), obeys the Newton's Universal Law of Gravitation, which states that the force (always attractive) is proportional to the product of  the masses and inversely proportional to the square of the distance between them (this as a consequence of our Universe being three-dimensional), as follows:

Fg =\frac{G*m1*m2}{r^{2}}

So, if one of the masses increases 6 times, the force between them will be directly 6 times larger, so the new magnitude of the force will be as follows:

Fg₂ = Fg₁*6 = 7*10²¹ N* 6 = 4.2*10²² N

lorasvet [3.4K]

Answer:

The force from the truck on the car is always equal to the force from the car on the truck.

Explanation:

According to Newton's third law; action and reaction are equal and opposite. Hence, when the big truck and small passenger car are involved in a collision, we expect that the force from the truck on the car is always equal to the force from the car on the truck. The forces on the car and the truck are equal in magnitude but opposite in direction.

This follows directly from Newton's third law of motion hence the answer above.

Why is a force required to keep a body moving with a uniform speed in a circular motion?
andrew-mc [135]
Because if there's no force on the object, then it just moves in a straight line.
