Answer:velocity=
Explanation:
We shall use conservation of energy to solve this problem
we have
Potential energy of King Kong at top of building = His kinetic energy at the bottom
Potential energy of an object =
= 20000 kg
Where m is mass of an object(20000 kg)
g is accleration due to gravity = 9.81
h is the height above the surface of earth = 1450 feet = 441.96 meters
Applying values we get
......................(i)
Now Kinetic energy is given by
.......................(ii)
Equating i and ii we get
86712.552 =

Applying values we get

Tbh ! All of them have lens but I would go with B.) Smart Phone
Hope This Helps !!!
Answer:
1.2 A
Explanation:
From the diagram attached, The three resistors are parallel because the each ends of the resistors are connected together. Since they are in parallel, the voltage across each resistor is the same. The voltage source connected in parallel to the resistors is 60 V. Therefore the voltage across the 50 Ω resistor is 60 V. Using ohm law:
Voltage (V) = Current (I) × Resistance (R)
V = IR
I = V/R
I = 60 V/ 50 Ω
I = 1.2 A
The current in the 50 Ω resistor is 1.2 A
Answer:
Greater than
Explanation:
Here, angular momentum is conserved.

When the cloud shrinks under the right conditions, a star may be formed.
Thus, Diameter of clouds are much higher than a star.
Moment of inertia of cloud is greater than the star's inertial.
so, angular velocity of the star would be greater than angular velocity of the rotating gas.
