Answer:
83000 m/s
Explanation:
Using
F = Bqv....................... Equation 1
Where F = Force experienced by the charge, B = magnetic field q = charge of the particle, v = speed of the particle.
make v the subject of the equation
v = F/Bq.................... Equation 2
Given: q = 5.2×10⁻¹⁹ Coulombs, F = 9.5×10⁻¹⁵ Newtons, B = 2.2×10⁻¹ Tesla
Substitute into equation 2
v = 9.5×10⁻¹⁵ /(5.2×10⁻¹⁹×2.2×10⁻¹)
v = 8.3×10⁴ m/s
v = 83000 m/s
Answer:
The first crew of four astronauts were to land on Mars in 2025. Then, every two years, a new crew of four would arrive.
Explanation:
look it up my dudeski
Force on -7 uC charge due to charge placed at x = - 10cm
now we will have
towards left
similarly force due to -5 uC charge placed at x = 6 cm
now we will have
towards left
Now net force on 7 uC charge is given as
towards left
Answer:
The Power output from Turbine B with the doubled blade will be X4 of the power output from Turbine A.
Explanation:
The Power generated by a wind turbine is governed by the equation:
P=0.5ρAV³
Where ρ= Air Density
A= Swept Area of the Blade =πr²
V= Wind Velocity
If they are subjected to the same wind, Air Density and Wind Velocity will be equal
For both turbines,
Let Air Density=1
Wind Velocity=1
Power from Turbine A = 0.5X1XπX1²=0.5π
Power from Turbine B (radius=2) = 0.5X1XπX2²=2π
Power from Turbine B/Power from Turbine A = 2π/0.5π=4
