Question

The world’s largest gold bar, worth ten million dollars in 2014, has a base measuring 46 cm ×

Answer 1

Answer:

a} 2400 N

b}240 kg

Explanation:

Pressure is force per unit area.

Given from the question that;

The pressure = 24000 Pa

Area = 0.46 * 0.22 =0.1012 m²

Calculating force from the formula;

P= F/A where P is pressure, F is force and A is area then

F= P*A = 24000*0.1012 = 2428.8 N

a) The weight is 2400 N  in 2 significant figures

b) Mass is calculated from the formula;

w= m* g  where w is weight, m is mass and g is acceleration due to gravity

2400 =  m * 9.81

m= 2400/ 9.81

m= 244.64

m= 240 kg { in 2 significant figures}
