Explanation:
You can solve for volume using radius or diameter.
Sphere Volume = 4/3 • π • r³ = ( π •d³)/6
We're given the diameter so let's use that.
Volume = PI * d^3 / 6
Volume = 3.14159 * 3.0^3 / 6
Volume = 3.14159 * 9 / 2
Volume = 14.137 cubic centimeters
Multiply by the fraction (1 kg/1000 gm).
Answer:
Explanation:
Let the incident intensity of light on the polariser is Io.
Let the angle of transmission is θ.
According to the law of Malus,
The intensity of light coming out form the polariser is given by
I = IoCos²θ
The mean or the average value of Cos²θ is 1/2
So, the intensity of light coming out from the polariser is
I = Io/2
Thus, the 50% of light is transmitted by the polariser.
Answer:
Explanation:
The sun sends out solar wind constantly - charged particles that can degrade visual sensors and the skin of spacecraft, and the occasional blast of a solar flare, which can send out clouds of charged ions that can disrupt communications and electronics on board probes and satellites.

To solve this problem it is necessary to use the concepts of Force of a spring through Hooke's law, therefore,
Where,
k = Spring constant
x = Displacement
Initially our values are given,
PART A ) With this values we can calculate the spring constant rearranging the previous equation,
PART B) Since the constant is unique to the spring, we can now calculate the force through the new elongation (0.38cm), that is
Therefore the weight of another person is 265.79N.
