Answer:
Explanation:
Given
ambient Pressure =98.10 kPa
(a)gauge pressure 152 kPa
we know
Absolute pressure=gauge pressure+Vacuum Pressure
=152+98.10=250.1 kPa or 36.27 psi
(b)
=67.5 Torr or 8.99 kpa
as 1 Torr is 0.133 kPa
=8.99+98.10=107.09 kPa or 15.53 psi
(c)
=0.1 bar or 10 kPa
Thus absolute pressure=98.10-10=88.10 kPa or 12.77 psi
as 1 kPa is equal to 0.145 psi
(d)=0.84 atm or 85.113 kPa
as 1 atm is equal to 101.325 kPa
=98.10-85.11=12.99 kPa or 1.88 psi
Folded mountains occur when the rocks push against each other.
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.
