Answer:
9.01amp
Explanation:
Power = V^2/R
Given that v = 11volts, P = 99watts
99 = 11^2/R
11×11 = 99R
121= 99R
R = 121/99
R= 1.22ohms
From ohms Law; V = IR
11volts = I × 1.22ohms
I = 11/1.23
I = 9.01 amp
The hand saw involved more power because you actually have to cut down. The electric one cut it down on its own
Answer: Option (2) is the correct answer.
Explanation:
Viscosity is defined as the ability of a liquid to resist its flow. When a substance has high viscosity then it is known as a viscous substance.
For example, honey has high viscosity.
Whereas a substance which has less viscosity is will be able to flow easily from one place to another.
For example, water has low viscosity.
So, when substance B is more viscous then it means it has high viscosity than substance A. Hence, substance B will flow slowly as compared to substance A.
Thus, we can conclude that substance B is found to be more viscous than substance A. This means that B flows slower at room temperature than A does.
Answer:
The absorption lines will shift to the red (become longer).
This is because of the extra distance that a wavelength λ must travel between the vibrations of the source producing the spectrum.
Note that the Doppler effect of the source is slightly different for light waves than it is for sound waves because sound waves require a medium in which to travel while light waves do not require such a medium (example air).
