Remark
There are 2 kinds of Beta Decay. This one is an example of a neutron becomes a proton and the emitted particle is an electron.
Mmm tricky.
Constant velocity means there's no net force acting on the puck!
So if there's no friction or air drag force to slow it down, you don't need any force to keep that puck moving.
Once it's in motion, it stays in motion.
(Mmm isn't that a Law of Newton?)
:D
QUESTION:
Will both buzzers sound in this circuit?
ANSWER:
No, Only first buzzer sound. It is because the 2nd buzzer doesn't connected.
The plane is straight above the package when it hits the ground.
Find in what way long a free fall from a height of 4240 m takes: s = 1/2 gt^2
t^2 = 2s/g
t^2 = 2* 3880/9.8 = 791.8367
t = √791.8367
t = 28.1396 seconds
Now find the horizontal displacement with v = 292 m/s in 28.1396 s:
s = v*t
s = 292 * 28.1396 = 8216.76 m
