D
Explanation:
they can see this along with many other fish.
Answer:
Cu 8.92
Explanation:
The formula for density is mass/volume. If you were to divide 62.44 by 7, you would get 8.92. Since copper is the only metal in this table that has a density of 8.92, that is the answer.
Answer:
in the acceleration process the quantity α and w must increase
the deceleration process the alpha quantity must constant a direction opposite to the angular velocity
Explanation:
Acceleration and angular velocity are related to linear
v = w xr
a = αx r
The bold letters indicate vectors and the cross is a vector product, therefore if
we can see that the relationship between linear and angular variables is direct
therefore in the acceleration process the quantity α and w must increase as well as their linear counterparts
in the deceleration process the alpha quantity must constant as the linear acceleration and must have a direction opposite to the angular velocity
Answer:
Explanation:
We know that there is a relation between the speed of light ,frequency and wavelength.This relation can be given as 
where v is speed of light 
is frequency of light 
is wavelength of light
In first case we have given λ=655 nm
so using formula
Hz
In second case we have wavelength 515 nm so by using above formula
In third case we have wavelength 475 nm
so
