Answer:Time constant gets doubled
Explanation:
Given
L-R circuit is given and suppose R and L is the resistance and inductance of the circuit then current is given by
![i=i_0\left [ 1-e^{-\frac{t}{\tau }}\right ]](https://tex.z-dn.net/?f=i%3Di_0%5Cleft%20%5B%201-e%5E%7B-%5Cfrac%7Bt%7D%7B%5Ctau%20%7D%7D%5Cright%20%5D)
where
is maximum current
i=current at any time


thus if inductance is doubled then time constant also gets doubled or twice to its original value.
Correct option: D. Earthquakes along the San Andreas fault in California.
The earthquakes occur when the two plates collide with each other. Hence, there is contact between the two plates. So, the contact forces are responsible for the earthquakes.
The force responsible for Jupiter's moons to stay in orbit or the high tides occurring on the east coast is the gravitational force, which is not a contact force as there is no contact between Jupiter and its moon or the earth and the moon which is responsible for the high tides.
Moreover, the magnetic force is a non contact force as it attracts the pins from a distance without any contact between them.
Answer:
lol While plastic and wood aren't great thermal conductors, they conduct heat faster than air does. Even if the toilet seat is at the same temperature as the air around it, it will feel colder to your but t because heat will move from your skin to the seat at a faster pace Air just doesn't conduct heat very quickly.
Explanation:
The temperature of the air is -27°C
<u>Explanation:</u>
Given:
Frequency (f)=620 Hz
Wavelength (λ)=0.5 m
To Find:
Temperature of air = ?
Formula to be used:

Solution:

velocity at the current temperature v=fλ

Temperature of the air is given by the expression

Thus the temperature of the air is -27°C
