Answer:
ΔE / E = ΔV / V + Δd / d
Explanation:
The electric field and voltage are related by the expression
E = V / d
The uncertainty of the field is
ΔE / E = ΔV / V + Δd / d
We see that the uncertainty of the field must be added the uncertainty of the distance that in the measure of the different potential has no effect.
The only case in which the uncertainties are equal is if the distance measurement has no uncertainty, or the separation of very high
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!!!
What is wrong with the diagram is : ( 4 )
- The spot with the "maximum kinetic energy" should be on the lowest point of the roller coaster at the far left side on the bottom.
<h3>Gravitational potential energy vs kinetic energy</h3>
The maximum gravitational potential energy is located at the highest peak which the roller coaster attains while as the roller coaster comes down from the peak the gravitational potential energy decreases while the kinetic energy increases.
The point at which the roller coaster should attain it maximum kinetic energy should be at the lowest point ( i.e far left side of the bottom ).
Hence we can conclude that error in the diagram is the spot with the "maximum kinetic energy" should be on the lowest point of the roller coaster at the far left side on the bottom.
