Please write in proper english. I don't understand your point/question.
Explanation:
Assuming a student pushes a 51. 5 kilogram bookshelf across a smooth floor with a net force of 67 n the acceleration is 1.30m/s².
<h3>Acceleration</h3>
Using this formula
Acceleration= Net force/Mass of bookshelf
Where:
Mass of bookshelf =51.5 kilogram
Net force =67 Newton
Let plug in the formula
Acceleration=67n/51.5 kilogram
Acceleration=1.30 m/s²
Inconclusion the acceleration is 1.30m/s².

Answer: The answer is the first one and the last one.
Explanation: If an account cost $1 and each song is 1.5x. It has to be less than or equal to 25. So it would be $1 for (the account plus) 1.5x for (how many songs he buys) is less than or equal to 25 (the ammount on the gift card).
The watts that are consumed in a circuit that is having power factor of 0.2 and input is 100V at 4 ampheres is 80 watts.
Given that power factor is 0.2, input is 100V and electricity current be 4 amperes.
We are required to find the number of watts that are consumed in circuit.
An electric current is basically a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space.
Power factor is basically the ratio of working power, measured in kilowatts , to apparent power, measured in kilovolt amperes.
Number of watts that are consumed will be=100*0.2*4
=80 watts
Hence the watts that are consumed in a circuit that is having power factor of 0.2 and input is 100V at 4 ampheres is 80 watts.
