Answer: 57.018\times10^{-26}J

Energy is directly proportional to the frequency.

The energy of a photon is given by:

E=h\nu

Where, E is the energy and \nu is the frequency.

Frequency of the radio wave is given:

\nu=8.6\times10^8 Hz

h=6.63\times10^{-34}J.s

Multiply the above two:

Energy,

E=h\nu=6.63\times10^{-34}J.s\times8.6\times10^8 Hz= 57.018\times10^{-26}J

Hence, the energy of each photon of radio wave having frequency  \nu=8.6\times10^8 Hz is 57.018\times10^{-26}J

Explanation:

Given that,

Initial speed of the bag, u = 7.3 m/s

Height above ground, s = 24 m

We need to find the speed of the bag just before it reaches the ground. It can be calculated using third equation of motion as :

v^2=u^2+2as

v^2=(7.3)^2+2\times 9.8\times 24  

v=\sqrt{523.69}

v = 22.88 m/s

So, the speed of the bag just before it reaches the ground is 22.38 m/s. Hence, this is the required solution.

Precautions to be taken for the displacement method
finlep [7]

Volume by Displacement. The displacement method (submersion, or dunking method) can be used to accurately measure the volume of the human body and other oddly shaped objects by measuring the volume of fluid displaced when the object is submerged.

The following precautions should be taken very observantly:-

The line of sight must be perpendicular to measuring scale to avoid parallax error. Formation of bubbles inside the cylinder should be completely avoided. Any bubbles within leads to wrong measurements.
