An order-of-magnitude estimate of the volume of this balloon in cm3
IS 4 as it will be in few 10000cm^3 in volume 25*25*25
Answer:
The magnetic field strength is 2.11 T.
Explanation:
It is given that,
Length of the wire, L = 37 cm = 0.37 m
Current, I = 3.2 A
Force, F = 2.5 N
Magnetic force is given by :
Here,
We know that,
Velocity,
Since,
B = 2.11 T
So, the magnetic field strength is 2.11 T. Hence, this is the required solution.
Answer:
Ос.
The spacing between particles increases.
Heat causes greater particle activity, and the particles
are farther apart.
