The frequency of light from a laser is 4.878 x10^ 14 s-1 hertz

<h3>Steps</h3>

v= c/ lambda

c= 3.00 x10^8 m/s

nm into meters

615nm (1m/ 1x10^9 nm) = 6.15x 10^-7 m

use frequency formula

v = 3.00 x10^8 m/s // 6.15 x10 ^-7

v = 4.878 x10^ 14 s-1 hertz

The frequency of light from a laser is 4.878 x10^ 14 s-1 hertz

<h3>What do you mean by frequency?</h3>
  • The quantity of waves that pass a set location in a predetermined period of time is known as frequency.
  • Therefore, if a wave passes through in half a second, the frequency is 2 per second.
  • The frequency is 100 times per hour if it takes 1/100 of an hour.

The decarboxylation reaction involves the removal and replacement of a carboxyl group with hydrogen.

<h3>What is a decarboxylation reaction?</h3>

A decarboxylation reaction is one in which the carboxyl group in a carboxylic acid is replaced with hydrogen.

In living organisms, decarboxylation reactions are catalyzed by enzymes called decarboxylases or carboxy-lyases.

The decarboxylation of beta-carbonyl esters proceeds through a cyclic transition state giving an enol intermediate which then tautomerises to the carbonyl.

Therefore, a decarboxylation reaction involves the removal and replacement of a carboxyl group with hydrogen.

For maximum benefit, you should exercise 5-7 times a week for 60 minutes and your heart rate should be between _____________ of
lana [24]

Answer:

60 to 80%

Explanation:

For maximum benefit, the heart rates during exercise regimes should be between<u> 60 to 80% </u>of an individual's maximum heart rate.

<em>The maximum heart rate varies from individuals to individuals and largely depends on age. It is calculated by subtracting one's age from 220. For example, a person that is 40 years old would have a maximum heart rate of;</em>

<em>   220 - 40 = 180 beats per minute.</em>

Such a person's heart rates during exercises should be between 108 and 144 beats per minute for maximum benefits.

Help!!
Anna [14]

Compute the work done on the table:

<em>W</em> = <em>Fd</em> = (320 N) (32 m) = 10,240 J

Divide this by the given time duration to get the power output:

<em>P</em> = <em>W</em>/∆<em>t</em> = (10,240 J) / (150 s) ≈ 63.3 W

A 75kg man goes up a tower 30 m in 120s. How much power did the man exert
Pepsi [2]

Explanation:

If g= 10m/s²

Then 75kg=75×10=750N

Since Work =Force ×Distance

Work=750×30

=22500J

And Power°=Work÷time

=22500÷120

=187.5W
