Hooke's Law
F = k. Δx
Δx = 30 cm = 0.3 m
200 = k . 0.3
the spring stretch for 100 N:
Answer:
power requirement is 23.52 × W
Explanation:
given data
flow rate q = 2 m³/s
elevation h = 1200 m
density of the water ρ = 1000 kg/m³
to find out
power requirement
solution
we will get power by the power equation that is
power = ρ× Q× g× h ...................1
put here all value we get power
power = ρ× Q× g× h
power = 1000 × 2 × 9.8 × 1200
power = 23.52 ×
so power requirement is 23.52 × W
Convection currents are driven by the buoyancy
that results from density differences.
The density is about 3.88. You just have to divide the mass and the volume. You can check this on a calculator, too. Hope this helped
Answer:
The stored energy is 140.7 watt.
The thermal energy is 62.7 watt.
The delivered energy is 203.4 watt.
Explanation:
Given that,
Inductance = 2.8 H
Resistance = 12 Ω
Potential
Time = 0.086 s
(a). We need to calculate the energy stored in the magnetic field
Using formula of current
Using formula of energy
On differentiating
Again differentiating
Put the value into the formula
(b). We need to calculate the thermal energy
Using formula of thermal energy
Put the value into the formula
(c). We need to calculate the delivered energy by the battery
Using formula of energy
Hence, The stored energy is 140.7 watt.
The thermal energy is 62.7 watt.
The delivered energy is 203.4 watt.
