Answer:
From certain assumptions that the walking speed is 2 m/s, and the stop time is 0.1 s the acceleration would be -20 m/s
Explanation:
Using the average acceleration formula:
where and are the changes in the speed and time respectively.
We have by assuming that the walking speed is 2 m/s and the stop time is 0.1s which is equal to the change in time during the stopping.
, where are the initial speed and final speed respectively, and
Plugging the previous in the average acceleration formula we get
where the minus sign indicates an acceleration in the opposite direction of the motion (or in other word opposite to the speed's direction).
Answer:
broken pieces of glass from a window can't form a shadow.
Explanation:
the reason is that shadow is formed only when light rays hits an opaque object, which doesn't let light to pass through it, but glass is a transparent object, hence light rays passes through it forming no shadow..

Answer:
Magnetic field in Tesla: 1.65*10^−10 T, 0, 3.09*10^−10 T
Explanation:
Given data:
i = 4.8 A ,
dBx = 1.65*10^-10 T
dBy = 0 T
dBz = 3.09 * 10^-10 T
Attached below is the detailed solution
