The mass of lead = 22,939 kg
<h3>Further explanation</h3>
Given
mass alcohol=1600 kg
The density of lead =11300kg\m³ and density of alcohol=790kg\m³
Required
mass of lead
Solution
the volume of lead=volume of alcohol=2.03 m, so the mass of lead :
Answer:
The time required for one cycle, a complete motion that returns to its starting point,it is called periodic motion

I hope this will help you:)
Explanation:
Given:
Force, F = 83 N
D1 = 125 mm
R1 = 62.5 × 10-3 m
Mass of the car = 1100 kg
Force of the car = mass × a
= 1100 × 9.81
= 10791 N
Pin = Pout
Pressure = Force ÷ area
Area = pi × R^2
83/(pi × (62.5 × 10^-3)^2 = 10791/Aout
83/(pi × (62.5 × 10^-3)^2 = 10791/(pi × R2^2
R2 = 0.712 m
2 × R2 = D2
= 1.43 m
The answer is A.) decrease.
Take pushing a box for example. You push your hardest but then give out, still trying to push. You're doing less work than what you started with.
