ummmmm mmmmm butterflies :)
Explanation:
Answer:
The resistance of the lamp is 4Ω.
Explanation:
You have to apply voltage formula :
V = I × R
R = V ÷ I
R = 240 ÷ 60
R = 4 Ω
Answer:
In this case the net force is zero.
According to Newton's third law of motion: For every action, there is an equal and opposite reaction. In this case the net force is zero.

Answer: 714.285 nm
Explanation:
The diffraction angles 
when we have a slit divided into 
parts are obtained by the following equation:
(1)
Where:
is the width of the slit
is the wavelength of the light
is an integer different from zero
Now, the first-order diffraction angle is given when 
, hence equation (1) is rewritten as:
(2)
We know:
In addition we are told the diffraction grating has 700 lines per mm, this means:
Solving (2) with the known values we will find :
(3)
(4)
Knowing 
:
This is the wavelength of the light
