density of silver is 10.5 X10^3 kg/m^3. find the volume occupied by 2X10^4 g of silver. calculate the force of gravity acting on the mass.
volume= mass/density= 20kg/(10.5E3kg/m^3)
= ???
To find the volume occupied by 2x10^4 g of silver, we can use the formula:
Density = Mass / Volume
We are given the density of silver as 10.5x10^3 kg/m^3. However, the mass given to us is in grams, so we need to convert it to kilograms first:
Mass = 2x10^4 g = 2x10^4 / 1000 kg = 20 kg
By rearranging the formula, we can solve for volume:
Volume = Mass / Density
Volume = 20 kg / 10.5x10^3 kg/m^3 = 0.001905 m^3
Therefore, the volume occupied by 2x10^4 g of silver is 0.001905 m^3.
Next, to calculate the force of gravity acting on the mass, we can use the formula:
Force = Mass * Acceleration due to gravity
Acceleration due to gravity is approximately 9.8 m/s^2.
Force = 20 kg * 9.8 m/s^2 = 196 N
Therefore, the force of gravity acting on the mass is 196 Newtons.
