Answer:
v=12.5 i + 12.5 j m/s
Explanation:
Given that
m₁=m₂ = m
m₃ = 2 m
Given that speed of the two pieces
u₁=- 25 j m/s
u₂ =- 25 i m/s
Lets take the speed of the third mass = v m/s
From linear momentum conservation
Pi= Pf
0 = m₁u₁+m₂u₂ + m₃ v
0 = -25 j m - 25 i m + 2 m v
2 v=25 j + 25 i m/s
v=12.5 i + 12.5 j m/s
Therefore the speed of the third mass will be v=12.5 i + 12.5 j m/s
It is a completely false statement that in <span>any energy transformation, there is always some energy that gets wasted as non-useful heat. The correct option among the two options that are given in the question is the second option. I hope that this is the answer that has actually come to your desired help.</span>
When a red giant has insufficient mass it pretty much sheds its outer layer to leave the center core know as the white dwarf
Liter
The Basic Unit for Volume
The liter, which is the basic unit of volume, was originally defined as the volume occupied by 1 kilogram of water, but today it's simply one-thousandth of a cubic meter
BRAINLY PLS
W boson has +1e or - 1e charge, Z boson has 0 charge.
Leptons have +1e, -1e or 0 charge.
Photons have 0 charge.
Only quarks have a charge of +2/3e or -1/3e of an electron charge.
To be exact, only up-type quarks (Up, Down and Top quarks) have a +2/3e or two thirds of an electron charge.
So the correct answer is D) Quark.
