Answer:
F = 8066.67 N
Explanation:
The extra force exerted on the bottom of the jug can be expressed as the pressure generated by the cork multiplied by the area of the bottom. We can also obtain the Pressure P by dividing the force F1 applied to the cork by it's area A1.
Thus;
F = PA2 = (F1/A1) x (A2)
F = (F1/(πd1²/4)) x (πd2²/4)
π/4 will cancel out to give;
F = F1(d2/d1)²
F = 150(16.5/2.25)
F = 8066.67 N
Answer : 96 candelas
Explanation : Luminous intensity is a quantity of light that is emitted by a light source with a solid angle in a particular direction.
We know the formula of luminous intensity
Luminous intensity = illuminance x distance from light source



So, the intensity of the source will be 96 candelas.
Answer:
F = 20.07 μN
Explanation:
given,
intensity of sunlight = 667 W/m²
area of surface = 9.03 m²
speed of light = 3 x 10⁸ m/s
force = ?
we know
force =
force =
F = 20.07 x 10⁻⁶ N
F = 20.07 μN
Answer:
The forces offset to produce a net force of 8 N
since the ball is 1 kg
F = ma
a = f/m = 8 N/1 kg = 8 (kg m)/(s^2 kg) = 8 m/s^2
