Answer:
0.027 N
Explanation:
From the question,
According to Archimedes principle,
The buoyancy force on the material = weight of oil displaced by the solid cube = Upthrust on the solid cube.
Applying,
U =ρ×V×g................ Equation 1
Where U = Upthrust on the solid cube, ρ = density of oil, V = Volume of the solid cube, g = acceleration due to gravity
But,
V = l³................ Equation 2
Substitute equation 2 into equation 1
U = gρl³.............. Equation 3
Given: ρ = 820 kg/m³, l = 1.50 cm = 0.015 m
Constant: g = 9.8 m/s²
Substitute these values into equation 3
U = 820×0.015³×9.8
U = 0.027 N
Answer:
The pendulum clock does it loses 83.0304 seconds a day at the new location.
Explanation:
T1= 1 s
T2= ?
g1= 9.8135 m/s
g2= 9.7943 m/s
L=?
L= (T1/2π)² * g1=
L= 0.24857m
T2= 2π * √(L/g2)
T2= 1.000961 s
ΔT= T2 - T1
ΔT = 0.000961 s
seconds lost a day = 24 * 3600 * ΔT
seconds lost a day= 24 * 3600 * 0.000961 s
seconds lost a day= 83.0304 s
