Answer:</h3>
Distance = 7 m
Power = 12.5 J/s or watts
<h3>
Explanation:</h3>
Work done = 175 Joules
Force exerted = 25 Newtons
Work done is the product of force exerted and the distance moved by a body.
Therefore;
Work done = Force × distance
Rearranging the formula we can work out the distance;
Distance = work done ÷ Force
= 175 J ÷ 25 N
= 7 m
Thus, the grand piano was moved by 7 m across the living room .
On the other hand,
Power is the rate at which the work is done.
Therefore;
Power = Work done ÷ time
Work done = 175 Joules
Time = 14 seconds
Thus;
Power generated = 175 J ÷ 14 sec
= 12.5 J/s or watts
Hence, a power of 12.5 J/s was generated in moving the grand piano.
Uhh I think d sorry if wrong ;-;
Answer:
the left one
Explanation:
heavier means it goes faster
Atomic number of an element correlates to the number of protons an atom of that element will have. An atom of this element would have 63 protons.
Answer:
Above 7
Explanation:
The equivalence point of any titration can be read off from the appropriate titration curve.
A titration curve is a plot of the pH of analyte against the volume of titrant added.
For a strong base and weak acid, the equivalence point lies above 7.
