Both are aquatic animals and are hunters
Explanation:
Answer:
Power of the string wave will be equal to 5.464 watt
Explanation:
We have given mass per unit length is 0.050 kg/m
Tension in the string T = 60 N
Amplitude of the wave A = 5 cm = 0.05 m
Frequency f = 8 Hz
So angular frequency 
Velocity of the string wave is equal to 
Power of wave propagation is equal to 
So power of the wave will be equal to 5.464 watt
The SI unit of length or distance is the meter.
Answer:
Half
Explanation:
You only have to exert a force equal to half the weight of the load to lift it.
