It would be very chaotic... For example anything that was not attached to the Earth will probably go flying off into space in the straight linear line. if you're already disappeared the Earth's atmosphere would float in space so other planet's atmospheres would also float into space... planets will break apart into pieces and go off in space and planets are held together by gravity period. Imagine gravity is a string, once you look over that string or quote unquote "turn off" gravity, everything will go flying into linear lines on to the vastness of the cosmos. I hope this helps if you need any more examples for any other questions please let me know have a blessed day. :-)
Answer:
Option C, The total momentum of the fragments is equal to the original momentum of the firecracker.
Explanation:
Kinetic energy of cracker cannot remain constant before and after explosion. It is so because in the process of burning and bursting some amount of kinetic energy is lost in the form of light and heat energy. While the total mass before and after the explosion remains constant due to which the momentum is conserved before and after the explosion
Hence, option C is correct
Answer:
Magnetic field can be used to produce current, infact a changing magnetic field can produce current.
A changing magnetic field in a loop causes the flux linked with the loop to change in turn generating a emf in the loop and therefore a current.
For a loop of area A and resistance R.
I =dPhi/dt/R
В. А
I = AcosФ/R .dB /dt
But it isn't reasonable to say that we can create a magnetic field by having a flow of current and this can be used to make more current because the current generated due to change in magnetic field created by increase/decrease in flow of current will be in a direction such that it will counter act the change in magnetic field caused by increase/decrease in current flow.(lenz's law).

Ф= В. А
I = Acos dB Rd
Answer:
-450 m/s
Explanation:
Momentum is conserved.
p₀ = p
0 = (1.5 kg) (1.5 m/s) + (0.005 kg) v
v = -450 m/s
