A student went to a hill station early in the morning, he could hear the echo of his clap after 0.1 second. When he went to the
Dahasolnce [82]

Answer:

See the explanation.

Explanation:

The speeds of sound depend upon the temperature of the medium. As the temperature increased in the afternoon, the speed of sound increases. Then the time taken by reflected sound will be less than 0.1 sec in the afternoon. And to hear an echo the time gap between an original sound and reflected sound must be at least 0.1 sec. That is why the student could not hear the echo at all in the afternoon.

The triceps muscle in the back of the upper arm extends the forearm. This muscle in a professional boxer exerts a force of 2615
mart [117]

Answer:

0.68 kg-m²

Explanation:

F = Force applied by the muscle = 2615 N

r = effective perpendicular lever arm = 2.85 cm = 0.0285 m

α = Angular acceleration of the forearm = 110.0 rad/s²

I  = moment of inertia of the boxer's forearm = ?

Torque is given as

τ = I α                                   eq-1

Torque is also given as

τ = r F                                   eq-2

using eq-1 and eq-2

r F =  I α

(0.0285)(2615) = (110.0) I

I = 0.68 kg-m²

How does the number of each type of particle in a sodium ion compare with the number of each type of particle in a sodium atom?
anyanavicka [17]
<h3><u>Answer and explanation;</u></h3>
  • <u><em>A neutral sodium atom contains 11 protons, 12 neutrons and 11 electrons. By removing an electron from this atom we get a positively charged Na+ ion that has a net charge of +1.</em></u> Thus; Sodium atom is neutral whereas sodium ion is a charged species with a charge of +1.
  • <u><em>Sodium ion is positively charged. In sodium ion, there are 11 protons and 12 neutrons but 10 electrons</em></u>, i.e., sodium ion contains lesser number of electrons. Additionally,the size of sodium ion is smaller than that of sodium atom.
