Answer:
9.47 rad/s^2
Explanation:
Diameter = 15 cm, radius, r = diameter / 2 = 7.5 cm = 0.075 m, u = 0, v = 7.1 m/s,
s = 35.4 m
let a be the linear acceleration.
Use III equation of motion.
v^2 = u^2 + 2 a s
7.1 x 7.1 = 0 + 2 x a x 35.4
a = 0.71 m/s^2
Now the relation between linear acceleration and angular acceleration is
a = r x α
where, α is angular acceleration
α = 0.71 / 0.075 = 9.47 rad/s^2
Answer:
0.0133A
Explanation:
Since we have two sections, for the Inductor region there would be a current 
. In the case of resistance 2, it will cross a current 
Defined this we proceed to obtain our equations,
For ,
For ,
The current in the entire battery is equivalent to,
Our values are,
Replacing in the current for t= 0.4m/s
Ionic is where the bonding of elements attract opposites
