Answer:
60 N.C
Explanation:
The box will move in the direction of the push and pull with a force of 60 N. C.
Answer:
Resistance of the circuit is 820 Ω
Explanation:
Given:
Two galvanometer resistance are given along with its voltages.
Let the resistance is "R" and the values of voltages be 'V' and 'V1' along with 'G' and 'G1'.
⇒ 
⇒ 
Concept to be used:
Conversion of galvanometer into voltmeter.
Let 
be the resistance of the galvanometer and 
the maximum deflection in the galvanometer.
To measure maximum voltage resistance 
is connected in series .
So,
⇒ 
We have to find the value of we know that in series circuit current are same.
For 
For 
⇒ 
equation (i) ⇒ 
equation (ii)
Equating both the above equations:
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ Plugging the values.
⇒ 
⇒ 
⇒ 
⇒ 
The coil resistance of the circuit is 820 Ω .

If you are talking about volume, then an easy way to measured the volume of a liquid would be with a graduated cylinder. A graduated cylinder is marked with volume units such as milliliter (mL) or the liter (L). One liter equals 1 thousand milliliters.
To measure the volume of a solid you use the formula V = (Length)(Width)(Height)
To measure the volume of a gas you use a graduated cylinder held upside down. At first the cylinder is filled with water. When air is blown into the cylinder, bubbles rise and push some water down. The volume of the water pushed down is equal to the volume of the gas that was blown in.
Social perception (or person perception) is the study of how people form impressions of and make inferences about other people as sovereign personalities.A real-world example of social perception is understanding that others disagree with what one said when one sees them roll their eyes.
