To solve this problem we need to use the proportional relationships between density, mass and volume, together with Newton's second law.
The force can be described as
Where,
m = Mass
g = Gravitational acceleration
At the same time the Density can be defined as
Where,
m = mass
V = Volume
Replacing the value of the mass at the equation of Force we have,
Since the difference between the two forces gives us the total Force then we have to
Where
Force of the water
= Force of plastic
Therefore with the values for this force we have,
Therefore the tension in the thread is 16.412N
so from what i was looking at i think the answer is d because The shorter the wavelength, the higher measure of vitality it produces.So the request is D. Bright beams, Visible light, Infrared, and Microwaves.

Answer:
C. 8.4 × 10^2 volts
Explanation:
The potential energy of a charge is given by:
where
q is the magnitude of the charge
V is the electric potential
In this problem, we have
is the charge
is the potential energy
Re-arranging the formula and using these numbers, we can find the electric potential:
Answer:
The magnification would be "103.55". A further explanation is given below.
Explanation:
The given values are:
Distance between lens and eyepiece,
L = 85 cm
Eyepiece is,
= 123 D
Now,
The refractive power of eye piece will be:
⇒ 
The length of the telescope will be:
⇒ 
⇒ 
On substituting the values, we get
⇒ 
⇒ 
Now,
The magnification of the telescope will be:
⇒ 
⇒ 
⇒
