<h3>
Answer:</h3>
5.395 × 10^8 Watts
<h3>
Explanation:</h3>
<u>We are given;</u>
- Rate of flow is 1.1 × 10^6 kg/s
- Distance is 50.0 m
- Gravitational acceleration is 9.8 m/s²
We are required to calculate the power that is generated by the falling water
- Power is the rate of work done
- It is given by dividing the energy or work done by time
But; work done = Force × distance
Therefore;
Power = (F × d) ÷ time
The rate is 1.1 × 10^ 6 Kg/s
But, 1 kg = 9.81 N
Therefore, the rate is equivalent to 1.079 × 10^7 N/s
Thus,
Power = Rate (N/s) × distance
= 1.079 × 10^7 N/s × 50.0 m
= 5.395 × 10^8 Watts
The power generated from the falling water is 5.395 × 10^8 Watts
Answer:
Explanation:
Given that,
The radius of a flywheel, r = 0.3 m
Angular acceleration of a flywheel, 
We need to find the magnitude of the tangential acceleration after 2.00 s of acceleration.
The relation between the tangential and angular acceleration is given by :
So, the required magnitude of tangential acceleration is .
Answer: What is the difference of physical quanity and a unit?
Explanation: If you are working science or math problems, the answer to this question is that quantity is the amount or numerical value, while the unit is the measurement. For example, if a sample contains 453 grams, the quantity is 453 while the unit is grams.
Answer:
In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. ... For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes.
