If hunter fires a bullet 2 degree below the horizontal
then the components of its speed is given as
so here initial speed of the bullet is not zero but have some magnitude in downwards direction
While the other bullet is dropped downwards so its initial speed will be zero
So here we can say
so if we use above equation we will find that the bullet that is shot at 2 degree below the horizontal will reach the ground first as its speed is more
Answer:
Ein: 2.75*10^-3 N/C
Explanation:
The induced electric field can be calculated by using the following path integral:
Where:
dl: diferencial of circumference of the ring
circumference of the ring = 2πr = 2π(5.00/2)=15.70cm = 0.157 m
ФB: magnetic flux = AB (A: area of the loop = πr^2 = 1.96*10^-3 m^2)
The electric field is always parallel to the dl vector. Then you have:
Next, you take into account that the area of the ring is constant and that dB/dt = - 0.220T/s. Thus, you obtain:
hence, the induced electric field is 2.75*10^-3 N/C
