Answer:
C
Explanation:
For a uniformly distributed mass, the center of gravity is also the geometric center. For this shape, the center is at point C.
Answer:
864 KN
Explanation:
(Absolute pressure) = (Atmospheric pressure) + (Gauge Pressure)
Atmospheric pressure = 95 KPa = 95000 Pa
Gauge Pressure = ρgh
ρ = density of the fluid = 1000 kg/m³
g = acceleration due to gravity = 9.8 m/s²
h = depth below the fluid level that the object is at = 5 m
Gauge Pressure = 1000 × 9.8 × 5 = 49000 Pa
Absolute pressure = 95000 + 49000 = 144000 Pa.
Pressure = (Hydrostatic force)/(Area perpendicular to the force)
Hydrostatic force = (Pressure) × (Area perpendicular to the force)
Area perpendicular to the force = 2 × 3 = 6 m²
Hydrostatic force on the top of the plate = 144000 × 6 = 864000 N = 864 KN
Hope this Helps!!!
D because if you are heavier and standing higher up then you will have greater potential energy than someone who weighs less and is standing at a lower height.
Answer:
0.37 cm
Explanation:
The image is formed on the retina which is at a constant distance of 2.70 cm to the lens. Therefore, image distance = 2.70 cm.
The object is at a distant of 265 cm to the lens of the eye.
From lens formula,
= +
where: f is the focal length, u is the object distance and v is the image distance.
Thus, u = 265.00 cm and v = 2.70 cm.
= +
=
=
⇒ f =
= 0.37
The focal length of the eye is 0.37 cm.
