Changing frequency of sound does not change the speed of the sound.
Explanation:
- Speed of the sound gets altered when the sound travels from one medium to another.
- Change in frequency does not affect the speed of the sound and speed is affected by the properties of the medium through which it travels.
- Therefore, to change the speed of the sound, the properties of the medium needs to be changed.
Higher the mass will cause more friction which will make its temperature higher and it would also need more kinetic energy to move at a higher speed<span />
<h3><u>Answer;</u></h3>
A) Nerve cells group to form nerve tissue.
<h3><u>Explanation;</u></h3>
- <em><u>A cell is the fundamental basic unit of all living organisms. Nerve cells are specialized cells of the nervous system that carry impulses to and from the central nervous.</u></em>
- <u><em>Nerve cells form the nerve tissue.</em></u> They are the primary cells of the nervous system which are responsible carrying nerve impulses to cells in the body and tissues in other organ system.
- Nerve cells also called the neurons are of various types which includes, <em><u>the motor neurons, sensory neurons, and relay neurons, </u></em>depending on the direction of the information they carry.
Answer:
quark
Explanation:
neutrón= 1.675 x 10-27 kg
proton=1,673 x 10-27 kg
electron=9,11 x 10-31 kg
quark=7,13 - 14,26 · 10−30 kg
Answer:
-15 m/s
Explanation:
The computation of the velocity of the 4.0 kg fragment is shown below:
For this question, we use the correlation of the momentum along with horizontal x axis
Given that
Weight of stationary shell = 6 kg
Other two fragments each = 1.0 kg
Angle = 60
Speed = 60 m/s
Based on the above information, the velocity = v is



= -15 m/s
