Answer:
The answer is time
Explanation:
So when youre given force and distance, you can determine work done
Work Done = Force × Distance travelled in the
direction of the force
Since Power = Work Done/ Time
when you know work done, and you want to find power, you will need time.
Because you have work done already, you dont need energy. Though you can use energy and time to find work too. The alternative formula for Power would be:
Power = Energy Converted/Time
Answer:
C) the reactants have more potential energy than the products.
Explanation:
Answer:
The value is
Explanation:
Generally the moon's radial acceleration is mathematically represented as
Here
is the angular velocity which is mathematically represented as

substituting
for T(i.e the period of the moon ) we have
=>
From the question r(which is the radius of the orbit ) is evaluated as

substitute
for R and
H

=> 
So
Answer: Unspecific
A goal should NOT be unspecific
Answer:
The value is
Explanation:
From the question we are told that
The weight of the elevator is
The acceleration it is to be given is 
The diameter of the shaft is 
Generally the radius is mathematically represented as

=> 
=> 
Generally the minimum angular acceleration is mathematically represented as

=>
=>
