The radiation from this laser is 3.7 x 10^(-19)

<h3>Calculation</h3>

here ∨ = 5.69 x 10^(14) s-1

we know E=h∨

where h = 6.626 x 10^(-34) js

putting the value in the formula, we have,

6.626 x 10^(-34)  x 5.69 x 10^(-34)

=3.7 x 10^(-19)

<h3>What is radiation?</h3>

The energy emission in the form of electromagnetic waves or in the form of moving subatomic particles which are especially high-energy particles which cause ionization is called as the phenomenon of radiation.

Any kind of energy that emanates from a source and moves through space at the speed of light is referred to as radiation. This energy has wave-like qualities and is accompanied by an electric field and a magnetic field.

A 50kg hiker is standing on the edge of a cliff. Find the hiker’s gravitational potential energy if the cliff is 30m high. (Show
DENIUS [597]

Answer:

The answer to your question is:      Ep = 14715 Joules

Explanation:

Data

mass = 50 kg

Potential energy = ?

height = 30 m

g = 9.81 m/s²

Equation

                Ep = mgh

Substitution

                     Ep = (50)(9.81)(30)

                     Ep = 14715 Joules

A truck covers 40.0 m in 7.10 s while uniformly slowing down to a final velocity of 2.05 m/s.
Alona [7]

Answer:

(A) Original speed= 9.22 m/s

(B) Acceleration= -1.0099 m\s^2

Explanation:

A truck covers 40m in 7.10 secs

The truck slows down at a uniform velocity of 2.05 m/s

(A) The original speed can be calculated as follows

Vo= 2(40)/7.10 - 2.05

= 80/7.10 - 2.05

= 11.2676 - 2.05

= 9.22m/s

(B) The acceleration can be calculated as follows

a= Vf-Vo/t

= 2.05-9.22/7.10

= -7.17/7.10

= -1.0099m/s^2
