Answer:

The displacemnent of the nut will be 0.3 m.

Explanation:

As we know the torque (\large{\overrightarrow{\tau}}) is given by

\large{\overrightarrow{\tau} = \overrightarrow{r} \times \overrightarrow{F}}

where \large{\overrightarrow{r}} is the displacement and \large{\overrightarrow{F}} is the applied force.

Given, \large{|\overrightarrow{\tau}|} = 40 N-m and \large{|\overrightarrow{F}|} = 133 N

So the magnitude of the displacement of the nut is given by

\large{r} = \dfrac{\tau}{F} = \dfrac{40}{133} = 0.3 m

alexgriva [62]

Answer:

This is because white light consists of 7 colours with different angles o deviation or retraction.

Explanation:

When a narrow beam of light is refracted by a prism the light spreads into a band of colours (called the spectrum of light )

But in this case if a blue colour is observed it is due to the angle of refraction ,for instance red is refracted the least and hence is seen

What affects the amount of potential energy stored in the magnetic field when a magnet is moved against a magnetic force?
LekaFEV [45]

Answer: Strength of magnet and distance from magnetic material

Explanation:

The potential energy of a magnet is determined by the strength of the magnet and the distance between a magnet and another magnet or a magnetic material. Magnetic materials are materials that would be attracted when brought close to a magnet, example of magnetic materials are most metals.

What is the relation between acceleration due to gravity and radius of the earth? ​
emmasim [6.3K]

Answer:

As the earth is an oblate spheroid, its radius near the equator is more than its radius near poles. Since for a source mass, the acceleration due to gravity is inversely proportional to the square of the radius of the earth, it varies with latitude due to the shape of the earth.

Formula: g = GM/r2

Dimensional Formula: M0L1T-2

Values of g in SI: 9.806 ms-2
