<h3>
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.
Answer:
False
Explanation:
The Strong Nuclear Force is defined as an attractive force between neutrons and protons which is responsible to hold the nucleus together.
Electrostatic force is the repulsive or attractive force between two electrically charged objects.
Strong nuclear force is always greater than electrostatic force but changes with the distance. Strong nuclear attraction keeps the nucleus of an atom together in a small space as well which is stronger than their electrostatic repulsion.
it is said that, the strong nuclear force is the strongest force in the universe.
Hence, the given statement is false.

A 2.200-g sample of quinone (C6H4O2) is burned in a bomb calorimeter whose total heat capacity is 7.854<span> kJ/°C. The temperature of the calorimeter increases from 23.44 to </span>30.57 °C<span>. </span>
The name of the acid is Bromous acid and the Formula of the acid is HBrO₂.
<h3>What is Acids ? </h3>
Acids is defined as substances that is able to donate a proton or hydrogen ion to other substance. Acids acts as proton donor.
<h3>What is Oxoacids ? </h3>
An oxoacids is an acids that contains oxygen. It is also called oxyacids or ternary acids. Oxoacids are the acids of oxoanions.
If anion name contains the suffix ‘ate’ then replace ‘ate’ with ‘ic’.
If anion name contains the suffix ‘ite’ then replace ‘ite’ with ‘ous’.
Given anion is bromite. Formula of bromite is BrO₂⁻. It is an oxoanion.
Now write the name of acid. Here anion name contains the suffix ite so replace the ‘ite’ of bromite with ‘ous’.
The name of the acid is Bromous acid.
Formula of the acid is HBrO₂.
Thus from the above conclusion we can say that The name of the acid is Bromous acid and the Formula of the acid is HBrO₂.
