Answer:We have , a relation in frequency f and wavelength λ of a wave having the velocity v as ,
v=fλ ,
given f=60Hz , λ=20m ,
therefore velocity of wave , v=60×20=1200m/s
Answer:
A-Z
Explanation:
A proton has an estimated weight of 1.
Answer:
It would become a different element.
Explanation:
When you change the number of protons i.e, add a proton in the nucleus of an atom, you will change the atom from one element to a different element and also positive charge of the atom also increased by 1.
For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium.
So, we conclude that by adding a proton the atom will change from one element to another element.
Answer:
8,809.024m
Explanation:
Displacement , y = (gt^2/2
)
g = 9.8 m/s^2
t = 42.4s
y = (9.8 (42.4*42.4)) / 2
y = 8,809.024m
