Ultraviolet (UV) radiation can be subdivided into three regions: UVA, UVB, and UVC, based on their energy. What are the minimum
ruslelena [56]

Answer:

100nm-280nm

Explanation:

Ultraviolet rays (UV) are part of the electromagnetic spectrum. It goes from 10nm to 400nm wavelengths, they are shorter than visible light, thus it's impossible to see by a human eye, and larger than X-rays (used in many medical applications and harmful when long-exposed).

According to its wavelengths, UV can be divided in different types:

UVA: long wave UV (315nm-400nm)

UVB: medium-wave UV (280nm-315nm)

UVC: short wave UV (100nm-280nm)

Therefore, UVC comprises wavelengths between 10nm and 280nm.

What is the kinetic energy of a golf ball with a mass of 0.046 kg traveling at 15.5<br> m/s?
Serjik [45]

Answer:

<h2>5.53 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

m is the mass

v is the velocity

From the question we have

k =  \frac{1}{2}  \times 0.046 \times {15.5}^{2}  \\  = 0.023 \times 240.25 \\  = 5.52575

We have the final answer as

<h3>5.53 J</h3>

Hope this helps you

A metal block of mass 265 g rests at a point 2.4 m from the center of a horizontal rotating wooden platform. The coefficient of
FrozenT [24]

Answer:

The minimum angular velocity of the platform what whould the block slides away is w= 2.26 rad/s.

Explanation:

m= 0.265 kg

r= 2.4 m

μ= 0.257

g= 9.8 m/s²

W= m * g

W= 2.597 N

Fr= μ * W

Fr= 0.66 N

∑F = m * ac

W+Fr = m * ac

(W+ Fr) / m = ac

ac= 12.29 m/s²

ac= w² * r

√(ac/r)= w

w= 2.26 rad/s
