As we know that fundamental frequency is given as
here we know that
here we have
m = mass of wire = 5 g
l = length of wire = 90 cm
from above formula now
now we know that tension is due to weight of the sculpture so we will have
so its mass will be 11.76 kg
Answer:
electromagnetic waves only
Explanation:
I just took the test, Hope it helps!
- It helps in regulating extremes in the environment.
- It can be used as a car radiators.
<u>Explanation:</u>
- The amount of heat needed to raise a certain amount of temperature to the water is known as the specific heat of the water. For one gram of water to increase 1 degree celsius, water needs to absorb 4.184 J of heat.
Some of the uses of high specific heat of water are as follows,
- The temperature of the water will remain the same from day to night in ponds or sea. During day time, the hot air from the sea or pond rises while the cool air from the sea moves to take its place. During the night, the hot air from the land moves to take its place, giving rise to a land breeze and thus maintaining the environment.
- Another example, When water is circulated throughout an engine, heat will get absorbed. This water is pumped to a radiator and then disposed to the surrounding air.
