Option D
The resistance in machine is 8.5 ohms
<em><u>Solution:</u></em>
Given that,
Power = 1700 W
Voltage = 120 V
We have to find the resistance in machine
<em><u>The formula used is:</u></em>
Where,
"P" is the electric power and "V" is the voltage and "R" is the resistance
<em><u>Substituting the given values we get,</u></em>
Thus resistance in machine is 8.5 ohms

Answer:
the speed of the bird is 2.8 m/s in after 11 seconds.
Explanation:
given,
displacement of bird = 28 m
time taken of the displacement of 28 m = 11 s
distance = speed × time
velocity =
=
= 2.8 m/s
hence, the speed of the bird is 2.8 m/s in after 11 seconds.
Answer:
We can determine the age of the Earth and the rocks found on Earth with techniques such as measuring ice cores and digging and analysing fossils.
Explanation:
Hopefully this helped!
We'll use the formula Solubility = K * P where K is the Henry's constant and P is the pressure in atm.
If 1 bar = 0.9869 atm.
Then 4.5 bar = X atm
X = 4.4410
So Solubility = 58 * 4.4410 = 257.574 M
