A printer has a power of 100 W. It takes 30 seconds to print out a document. How much energy will ithave used?
Answers
A printer has power of 100 W, and it takes time of 30 seconds to print out the document, then the power consumed in 30 seconds will be 0.8333 W.
What is Power?
The quantity of energy moved or changed per unit of time is termed as power in physics. The watt, or one joule per second, is the unit of power in the International System of Units. Power is also referred to as activity in historical texts. A scalar quantity is power.
Power is connected to other factors; for instance, the power required to move a land vehicle is equivalent to the sum of the vehicle's velocity, traction force on its wheels, and aerodynamic drag.
Assuming the printer consumes electrical energy at a steady rate, then:
100 ÷ 60 = 1.6667 watts per minute.
Now, calculate the power consumed in 30 seconds,
1.6667 ÷ 2 = 0.8333 watts.
Therefore, the power consumed in 30 seconds will be 0.8333 watts.

100W translates to 100 watts consumed in 1 hour. Assuming the printer consumes electrical energy at a steady rate, then: 100 ÷ 60 = 1.6667 watts per minute. 1.6667 ÷ 2 = 0.8333 watts consumed in 30 seconds.

Answer : v = 69 m/s.
Explanation :
It is given that,
The momentum of a bald eagle in flight,
Mass of the eagle, m = 5 kg
We know that the momentum of any object is defined as the product of mass and the velocity with which it is moving.
The velocity of the eagle is 69 m/s.
Hence, this is the required solution.
▲v= ▲M/m
▲v=Velocity Change
▲M=Momentum Change
m=Mass
Plug in the information;
▲v=345/5
The answer is 69
B. Be in phase with each other
C. Have a different frequency than the resultant wave
D. Be traveling in the opposite direction of the resultant wave
Answers
Correct answer choice is:
B. Be in phase with each other.
____________________________________________________________
Explanation:
Components waves mix to produce a resultant with the equivalent wavelength but the amplitude which is bigger than the amplitude of both of the unique component waves, and this results in constructive interference, which states that the interference of two or more waves of identical frequency and phase, constructing in their respective reinforcement and constructing a single amplitude equivalent to the total of the amplitudes of the unique waves.
