Answer:
B'=1.935 T
Explanation:
Given that
magnetic field ,B= 0.645 T
We know that magnetic filed in the solenoid is given as
![B=\mu _0 n\ I](https://tex.z-dn.net/?f=B%3D%5Cmu%20_0%20n%5C%20I%20)
I=Current
n=Number of turn per unit length
μ0 =magnetic permeability
Now when the current increased by 3 factors
I'=3 I
Then the magnetic filed
![B'=\mu _0 n\ I'](https://tex.z-dn.net/?f=B%27%3D%5Cmu%20_0%20n%5C%20I%27)
![B'=\mu _0 n\ (3I)](https://tex.z-dn.net/?f=B%27%3D%5Cmu%20_0%20n%5C%20%283I%29)
B'=3 B
That is why
B' = 3 x 0.645 T
B'=1.935 T
Therefore the new magnetic filed will be 1.935 T.

Explanation:
Answer:
The 1st one is 0.19
The 2nd one is 0.45
It's right for both of them :)
Explanation:
Answer:
(a) 80.36 m/s^2
(b) 0.0933 second
Explanation:
initial velocity, u = 7.5 m/s
final velocity, v = 0 m/s
distance moved, s = 0.350 m
(a) Let a be the deceleration.
Use third equation of motion
![v^{2}=u^{2}+2\times a\times s](https://tex.z-dn.net/?f=v%5E%7B2%7D%3Du%5E%7B2%7D%2B2%5Ctimes%20a%5Ctimes%20s)
![0^{2}=7.5^{2}+2\times a\times 0.350](https://tex.z-dn.net/?f=0%5E%7B2%7D%3D7.5%5E%7B2%7D%2B2%5Ctimes%20a%5Ctimes%200.350)
a = 80.36 m/s^2
Thus, the deceleration is 80.36 m/s^2.
(b) Let the time taken is t
Use first equation of motion
v = u + a t
0 = 7.5 + 80.36 x t
t = 0.0933 second
