Gamma rays, visible light, and ultraviolet rays are the type of Electromagnetic and transverse waves.

Answer: Option B

<u>Explanation:</u>

Gamma rays, visible rays, ultraviolet rays are some of the few kinds of waves in electromagnetic spectrum which are classified based upon their wavelength or energy.

Electromagnetic waves are transverse in nature this is because a motion is created normal to the direction of propagation of waves. Since gamma rays, visible rays and ultraviolet rays are part of electromagnetic spectrum, they are transverse in nature.

Depending on circumstances, there are times when divers may wish to be positively, negatively or neutrally buoyant. True. False.

ser-zykov [4K]

Answer:

True

Explanation:

Buoyancy is the most important factors for divers. All they do underwater is to observe the life down there but they also have some other work. However, divers may want to be negatively buoyant when they want to go on deep exploration. When they reach a destination, they may want to observe and neutral buoyancy then will be useful. When they want to go back on surface, they’ll utilize positive buoyancy.

The force required to stretch a Hooke’s-law spring varies from 0 N to 63.5 N as we stretch the spring by moving one end 5.31 cm

Alika [10]

Answer:

Force constant will be 1195.85 N/m

Work done will be 1.6859 J

Explanation:

We have given the force, F = 63.5 N

Spring is stretched by 5.31 cm

So x = 0.0531 m

Force is given , F = 63.5 N

We know that force is given by $F=kx$

So $63.5=k\times 0.0531$

k = 1195.85 N/m

Now we have to find the work done

We know that work done is given by

$W=\frac{1}{2}kx^2=\frac{1}{2}\times 1195.85\times 0.0531^2=1.6859J$
