Answer:

Explanation:
= Mass of Bonzo
= Mass of Ender
= Initial Velocity of Bonzo = 2.2 m/s
= Initial Velocity of Ender = -2.6 m/s
From conservation of linear momentum


True. Classifying by similarities is the basis for biological classification.
Answer: the electromagnetic spectrum
Explanation:
I’m not sure but I think this is it!
Answer:
a
Explanation:
what the heck is a medium
Our values can be defined like this,



The problem can be solved for part A, through the Work Theorem that says the following,

Where
KE = Kinetic energy,
Given things like that and replacing we have that the work is given by
W = Fd
and kinetic energy by

So,

Clearing F,

Replacing the values


B) The work done by the wall is zero since there was no displacement of the wall, that is d = 0.
