Answer:
4000 km
Explanation:
as we know velocity of electromagnetic wave is c
frequency given (f) = 76 Hz
wavelength ?
using
λ
λ = 
λ = 
≈4000 km
so final answer λ = 4000km
Answer:
Only the 4 th statement is true that is bed 1 and 3 are older than 4.
Explanation:
The 5 beds are numbered from 1 to 5 , 1 being the lowest and 5 being the topmost bed.
We are given 4 statements and we have to find out which all are true.
(<u>a)Bed 4 is older than bed 2 </u>
This is wrong because the lower beds are older than beds that are higher.
<u>(b)Bed 3 is older than beds 2 and 4</u>
This is also wrong because the 2 is older than 3
(<u>c)Bed 5 is the oldest </u>
This is wrong because bed 1 is the oldest
(<u>d)Beds 1 and 3 are older than 4</u>
This is true as lower beds are older

If the Earth's core cools down, then one of the first things that would happen is that plate tectonic activity would slow down. Over time, the Earth would then dry up into this ball of dry soil because the heat of the Earth's core drives water up to the surface. Since the crust would be void of majority of liquid, it would shrink by an unknown amount.
Answer:when a white light falls on an object, the wavelength of maximum absorbance is removed by absorption and the remaining wavelength are reflected to the eye.
Explanation:Furthermore,this relationship entails that the color not absorbed is the color of the object,for example plants are green because they reflect green light and absorb red and blue light.
