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
When the continental drift occured, it moved all the land on earth around, therefore changing climates. If fossils of animals are found on a certain continent that doesn't support that species, it proves the drift happened because the climate used to be suitable for them, but now is not.
Answer:
A signal is produced.
Radio waves are modulated and amplified.
Radio waves are amplified and demodulated.
A signal is seen, heard, or used.
Explanation:
Communication is the method of transmitting information between two or more participants. A radio communication network is a set of static and wireless radio equipment developed to facilitate an entity by enabling particular modes of communication such as one-to-many and one-to-one communication. Radio waves are being used to transmit information spatially from the sender to receiver, by modulating the radio signal in the transmitter. The above steps explains the loop of the radio communication system.
True. The speed of any object will have faster acceleration, and eventually slow down due to gravity.
Answer:
200 km/hr
Explanation:
Since he goes 80km per hour, multiply this by 2.5 or two and a half hours.
80 x 2.5 = 200 km/hr.
