Answer:
(e) 3.2
Explanation:
We are given that vector C and D.
Let R be the magnitude of C+D.
According to question
R=3D
We have to find the ratio of the magnitude of C to that of D.
By using right triangle property
Hence, the ratio of the magnitude of C to that of D=3.2
(e) 3.2
20 centimeters. 100 centimeters in a meter. 100/5= 20
Answer:
If we are talking fusion. Yes they both use nuclear fusion.
if its fission or anything else no.
Bohr's equation for the change in energy is
where
h = Planck's constant
c == the velocity of light
λ = wavelength.
The velocity is related to wavelength and frequency, f, by
c = fλ
Let us examine the given answers on the basis of the given equations.
a. As λ increases, f decreases and ΔE decreases.
TRUE
b. As λ increases, f increases and ΔE increases.
FALSE
c. As λ increases, f increases and ΔE decreases.
FALSE
Answer:
As the wavelength increases, the frequency decreases and energy decreases.
The first law is about force or push and pull
