Given that,
mass m = 110 lbs
Force of gravity in Newton, F =?
Since,
1 lbs = 0.45 kg
110 lbs = 110* 0.45 = 49.5 kg
Since, force of gravity equals the weight of the body.
F = W = mg = 49.5 * 9.81
F = 485.595 N
Force of gravity will be 485.595 N.
In order for motion to occur net force is greater than 485.595 N.
Answer:
124.52 mL
Explanation:
from Boyle's Law,
PV = P'V' ................... Equation 1
Where P = Initial pressure of the gas, V = Initial volume of the gas, P' = Final pressure of the gas, V' = Final volume of the gas.
make V' the subject of the equation.
V' = PV/P'............. Equation 2
Given: P = 267 torr = (267×0.00131) = 0.34977 atm, V = 356 mL, P' = 1 atm
Substitute into equation 2
V' = (0.34977×356)/1
V' = 124.52 mL.
Hence the new volume of the balloon = 124.52 mL
Answer:
remove contamination; pollution ; test ground water and dirt .
Answer:
Use the principle of momentum
Initial momentum = final momentum
Momentum formula = Mass * Velocity
Explanation:
Use newtons second law F=ma, plug in the given values which gives us the answer of 22 kg for the mass
