The answer is Jupiter not neptune :)
Answer:
4 m/s
Step-by-Step Explanation:
E = mgh and h = E/mg
So if you put your numbers in the formula : h = 4000J/500 * 10
you will get h = 4/5 meters
use this , If the elevator moves from top to the ground in a constasnt acceleration you will have all energy (4000 J) transformed into acceleration to speed up its motion.
(All potential energy will be turned into movement energy). As explained in this formula;
mgh = mv²/2 , solve out (v) from the equation
v = √2gh = √2·10·4/5 (digits are together- not related to the problem, just for clarification) = 4 m/s
Answer the velocity of the elevator is
4 m/s
b. The object will have a decreasing moment of inertia.
c. The object will rotate with constant angular velocity.
d. The object will have an increasing moment of inertia.
e. The object will rotate with decreasing angular acceleration.
f. The object will rotate with constant angular acceleration.
Answer:
f. The object will rotate with constant angular acceleration.
Explanation:
We know that
τ = I α
τ=Torque
I=Moment of inertia of the object
α =Angular acceleration
The moment of inertia is constant for an object and it does not depends on the applied torque.
If applied torque is constant then the angular acceleration of the object will be constant because moment of inertia is constant.
If angular speed is constant then the angular acceleration will,be zero.But in this case object is having angular acceleration that is why it have varying angular speed.
Therefore option "f" is correct.

Explanation:
The x - component of the initial velocity is given as:
Ux = Vi cos theta
Ux = 100cos 60
Ux = 50m/s

b. knowledge; effort
d. labor; knowledge
The five factors of production are land, labor, capital, entrepreneurship, and knowledge. These are the resources necessary for the production of goods and services. Each factor represents a different type of resource used in the production process.
The five factors of production include land, labor, capital, entrepreneurship, and knowledge. These are the resources used in the creation of goods and services. Land refers to all natural resources used to produce goods and services, Labor is the effort people contribute to the production of goods and services, Capital includes all the resources made and used by people to produce and distribute goods and services, Entrepreneurship is the willingness and ability to take the risks involved in starting and managing a business, and Knowledge is the understanding and skills that people acquire through education, training and experience.
