It's a toss up between b and c.
Light which allows you to see things (you can't see light itself, otherwise you  wouldn't be able to see through the light !) often known as white light contains all the wavelengths of red orange yellow green blue indigo violet. So on that basis it's B.
But, if you pass "white light" through a prism spectrometer, you might also pick up Ultra violet and infrared among other wavelengths depending on the experiment. And that would lean the answer more to C.
I'd put 1p on the answer being B ... visible light spectrum ... I think

The place kicker on a football team kicks a ball from ground level with an initial speed of 4.00 m/s at an angle of 29.0° above
mafiozo [28]

Answer:

0.4 s

Explanation:

The time that the ball is in the air can be found with the next formula:

time = t = \frac{2v_{o}sen\beta}{g}

where v_{o} is the initial velocity of the ball, in this case:

v_{o}=4.00 m/s

β is the angle: β = 29.0°

And g is the acceleration of gravity: g=9.81m/s^2

Replacing all the values to find t, we have:

time = t = \frac{2(4m/s)sen(29)}{9.81m/s^2} = 0.4s

Thus, the ball is 0.4s in the air.

Explain what is the difference of physical and chemical weathering
shusha [124]
The difference is that physical weathering is a process that weathers rock without a chemical reaction or change. Chemical weathering changes the identity of rocks and it involves a chemical reaction or change.

A body is projected vertically upwards with a speed 100 m/s from the ground then distance it covers in its last second of its up
Valentin [98]

The distance travelled by the body on last second of its upwards journey is 4.935m

What is projectile motion?

A projectile is an object or particle that is launched toward the surface of the Earth and moves along a curved path only under the influence of gravity.

To solve this question, consider the horizontal distance to be H and

distance traveled by the body in the last second be d

H=U^{2} /2g

H=100^{2} /2*9.8

H=510.2m

Now time taken to reach a height of

510.2 m= \sqrt[n]{2H/g}

=10.2 seconds

Now,

s=ut+1/2gt^{2}

H-d= (100)(t-1)-1/2g(t-1)^{2}

510.2-d=100*9.2-1/2*9.8*9.2^{2}

d=4936m

So, the correct answer is '4.936m'.
