A cubic meter of water at room temperature has a weight of 9800 N at a location where g = 9.80 m/s²
Weight = Mass x Gravity
9800 = Mass x 9.8
Mass = 9800/9.8 = 1000kg
At a location where g = 9.77 m/s²
Weight = 1000 x 9.77 = 9770N
Specific weight = Weight per unit volume
= Weight/Volume
= 9770/1
= 9770N/m³
Density = Mass/Volume
= 1000/1
= 1000kg/m³
Weight = Mass x Gravity
9800 = Mass x 9.8
Mass = 9800/9.8 = 1000kg
At a location where g = 9.77 m/s²
Weight = 1000 x 9.77 = 9770N
Specific weight = Weight per unit volume
= Weight/Volume
= 9770/1
= 9770N/m³
Density = Mass/Volume
= 1000/1
= 1000kg/m³

Answer:
Explanation:
A cubic meter of water at room temperature has a weight of 9800 N at a location where g = 9.80 m/s²
Weight = Mass x Gravity
9800 = Mass x 9.8
Mass = 9800/9.8 = 1000kg
At a location where g = 9.77 m/s²
Weight = 1000 x 9.77 = 9770N
Specific weight = Weight per unit volume
= Weight/Volume
= 9770/1
= 9770N/m³
Density = Mass/Volume
= 1000/1
= 1000kg/m³
