Explanation

R = xS⁴  

When S = 5, R = 6  

So,  

6 = x × (5)⁴ = x × 625  

⇒ x = 6 / 625

Now find R when S = 8:  

R = (6 / 625) × (8)⁴ = (6 / 625) × 4096  

= 24576 / 625 = 39.3216

Explanation

Newton's Second law of motion:

The rate of change of momentum of any object is directly proportional to the applied force on the body.

Explanation

"Applied for" is the correct phrase when referring to seeking or requesting something, such as a job.

Example: "I have applied for a new job."

Explanation

The escape velocity of a body in the gravitational field of Earth is primarily dependent on the mass of the Earth and the radius of the Earth.

It does not depend on the mass of the body or the angle at which it is thrown.

The formula for escape velocity 𝑣e is given by:

Explanation

 Torque is the rotational analog of force and equals the rate of change of angular momentum.

Explanation

An Ethernet connection is the standard for wired internet connectivity, using Ethernet cables to connect devices like computers, routers, and modems to a network.

Other options like HDMI, USB, and VGA are used for different purposes, such as video or data transfer.

Explanation

In paper chromatography, the stationary phase is the paper, which is made of cellulose fibers.

It holds the sample in place while the mobile phase (solvent) moves through it.

Explanation

In a bomb calorimeter, reactions are carried out at constant volume.

This is because the calorimeter is designed to keep the volume constant during the reaction.

Any heat released or absorbed during the reaction causes a temperature change, which is measured to determine the heat of the reaction.

The constant volume ensures that the heat measured is solely due to the chemical reaction taking place

Without any external influences like changes in pressure or volume.

Explanation

The word geometry means measurement of the earth.

Euclid is known as Father of Geometry.

Euclid was a mathematician from Greece.
