Answer:
Explanation:you must first make a free body diagram of the block to place all the forces that act on the block there. You will have four forces. The normal force, the weight, the horizontal force in x (which is what they ask to calculate) and the friction force. Then you raise the equations and you clear the values. I attach the solution.
Answer:
36 volts
If the circuit has a current of 3 amps, and a 12 ohm resistor.
12 x 3 = 36volts
The answer to your question is True.
Hope this helped...even though your question has been answered seven days later.
Better late than never xD
<h2>Answer: Medium
</h2>
The medium is the main factor that differentiates a mechanical wave from an electromagnetic wave, since the first can not propagate without its existence, while the second can propagate regardless of whether the medium exists or not.
In addition, it is the medium that will define, the propagation speed of the wave, according to its specific physical characteristics.
Therefore, the <u>correct answer</u> is a.
C. A complete revolution is 360 degree. two revolution is 720.
