Answer:
2.9 g/cm³
Explanation:
From the question given above, the following data were obtained:
Mass = 236.376 g
Volume = 81.5 cm³
Density =?
Density can be defined as the mass of a substance per unit volume of the substance. It can be expressed mathematically as:
Density = mass /volume
With the above formula, we can obtain the density of the object as shown below:
Mass = 236.376 g
Volume = 81.5 cm³
Density =?
Density = mass /volume
Density = 236.376 / 81.5
Density = 2.9 g/cm³
Thus, the density of the object is 2.9 g/cm³

264.7miles per gallon
Explanation:
Given parameters:
Distance traveled = 264km
volume of gasoline = 23.3L
Unknown:
Gas mileage = ?
Solution:
We are to solve for the Gas mileage in miles per gallon. This will show how much gas was used per miles covered.
Convert km to miles
liters to gallon
1mile = 1.609km
1liter = 0.264gallon
In miles; 
= 164.1miles
23.3L = 23.3 x 0.264 = 0.62gallon
miles per gallon = 
= 264.7miles per gallon

Answer:
Similarly, if magnet is held stationary and the coil is moved away and towards the magnet, the galvanometer shows deflection in similar manner. It is also seen that, the faster the change in the magnetic field, the greater will be the induced emf or voltage in the coil.
