1
Explanation: that is the ratio
I can give you a search engine that could help you with all ir hw its called socratic it uses everything on the internet to search for answers it’s literally a search engine
Answer:
The bus
Explanation:
a = (v-u)/t
Where
a = acceleration
v = final velocity
u = initial velocity
t = time taken
For truck to get its acceleration,
a = (18-0)/5.5 = 3.27 ms⁻²
For bus to get its acceleration,
a = (24-0)/6 = 4 ms⁻²
As 4 > 3.27 bus has a greater acceleration.
Answer:
Magnetic field, B = 0.199 T
Explanation:
It is given that,
Radius of circular loop, r = 11.7 cm = 0.117 m
Magnetic flux through the loop, ![\phi=8.6\times 10^{-3}\ T/m^2](https://tex.z-dn.net/?f=%5Cphi%3D8.6%5Ctimes%2010%5E%7B-3%7D%5C%20T%2Fm%5E2)
The magnetic flux linked through the loop is :
![\phi=B.A](https://tex.z-dn.net/?f=%5Cphi%3DB.A)
![\phi=BA\ cos\theta](https://tex.z-dn.net/?f=%5Cphi%3DBA%5C%20cos%5Ctheta)
Here, ![\theta=0](https://tex.z-dn.net/?f=%5Ctheta%3D0)
![B=\dfrac{\phi}{A}](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7B%5Cphi%7D%7BA%7D)
or
![B=\dfrac{\phi}{\pi r^2}](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7B%5Cphi%7D%7B%5Cpi%20r%5E2%7D)
![B=\dfrac{8.6\times 10^{-3}}{\pi (0.117 )^2}](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7B8.6%5Ctimes%2010%5E%7B-3%7D%7D%7B%5Cpi%20%280.117%20%29%5E2%7D)
B = 0.199 T
So, the strength of the magnetic field is 0.199 T. Hence, this is the required solution.
