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}
