Answer:
The speed increases by square root 2 times.
Explanation:
Let the wave velocity initially be 'v' with tension in the string as 'T' of mass 'm'.
Given:
Initial length of the string (L₁) = L
Final length of the string (L₂) = 2L
Wave velocity in a stretched string of length 'L' is given as:
From the above equation we can conclude that if tension 'T' and mass 'm' remains the same, the wave velocity is directly proportional to the square root of length of the stretched string. Therefore,
Now, plug in the given values and solve for v₂ in terms of v₁. This gives,
Therefore, the speed of the wave is increased by square root 2 times.
Answer:
Explanation:
ω = v / R
where ω is angular speed of a point situated at distance R from axis and having a linear speed of v .
Given v = 150 m/s ; R =.10 m
ω = 150 / .10
= 1500 radian /s .
Final angular speed is 1500 radian /s .
Answer:
Transferring
Explanation:
It's just the transferring of heat
Electric Heating systems use electricity as a source of heat.
<u>Explanation:
</u>
Each heater consists of an electric resistor, which the heating element in it. The process involved is Joule Heating. It is the phenomenon in which, passage of electric current produces heat. Heat is generated when the electrons from the current and the positive ions of the conductor start interaction.
The presence of voltage difference makes an electric fields, which in turn accelerates the charges present in the conductors. When they collide with ions of conductor, heat gets generated, and emitted out, which we use for heating purposes.
94 electrons. protons and electrons are always the same, but neutrons are different.
