Equation for ke = 1/2mv^2
1) ke = 1/2 x 5000 x (2x2)
= 10,000J
2) ke = 1/2 x 4000 x (3x3)
= 18,000J
So Object 2 has more Kinetic Energy
Answer:
Explanation:
From the information given:
The motional emf can be computed by using the formula:
E = 0.72 volts
According to the question, suppose the wire segment was parallel, there will no be any emf induced since the magnetic field is present along the y-axis.
As such, for any motional emf should be induced, the magnetic field, length, and velocity are required to be perpendicular to one another .
Then the motional emf will be:
E = 0 (zero)
E = 1/2 kx^2
Make k the subject of formula.
Find the base units of E and x.
Replace back in the equation and find the base units of k.

4°
Explanation:
Given,
chord in the airstream, c = 2 m
speed, v = 50 m/s
lift per unit span = 1353 N/m
density of air, ρ = 1.225 kg/m³
Lift,
From the plot of c_L and angle of attack
Angle of attack is equal to 4°
