According to the impulse--momentum equation Ft = change in mv, a bungee jumper in fall has momentum which is reduced by the forc
1 answer:
Answer:
The answer is a. Jumper
Explanation:
The change in the momentum is represented by the equation
Acceleration of any body is calculated by the product of the mass of the body and with the velocity the same mass is moving.
Since it is mentioned in the statement that m is the mass of the jumper then velocity will also be of the jumper to calculate the change in the momentum.
If the mass of bugle cord is taken, then its velocity will be taken for the equation.

Answer:
T = 10010 N
Explanation:
To solve this problem we must use the translational equilibrium relation, let's set a reference frame
X axis
Fₓ-Fₓ = 0
Fₓ = Fₓ
whereby the horizontal components of the tension in the cable cancel
Y Axis
2 = W
let's use trigonometry to find the angles
tan θ = y / x
θ = tan⁻¹ (0.30 / 0.50 L)
θ = tan⁻¹ (0.30 / 0.50 15)
θ = 2.29º
the components of stress are
F_{y} = T sin θ
we substitute
2 T sin θ = W
T = W / 2sin θ
T =
T = 10010 N
Answer:
Work function of the metal is 3.24 eV.
Explanation:
It is given that,
Wavelength,
Let W is the work function of the metal. It is given by using Einstein's photoelectric effect equation. It is given by :
Since,
So, W = 3.24 eV
So, the work function of the metal is 3.24 eV. Hence, this is the required solution.
