Answer:
19.74m/s² approximately
Explanation:
using Newton's second law of motion
F=MA
where f is force
m is the mass and
a is acceleration
A=f/m
150/7.6=19.74
Hi Lsavagecurry
The mass of an object relates to weight. The definition of mass is weight, like how heavy something is, say for example I have a balance scale which is the picture below and I put a rock on one side and 4 more smaller rocks on the other side, of course its balanced, u might have thought one or the other is stronger but its equal because the 4 rocks were not as big as the one on the left, they were smaller but due to their quantity it equaled their same mass, but another ex is I put a elephant and a mouse on a scale, who has more mass, answer is elephant because it weighs way more than a mouse, and a mouse barely weighs anything, but its not because of mass only, if maybe there were a billion mouses against that elephant on a scale maybe they could balance it, quantity can also help as well. I hope this helps you with your question and I take no credit for the images below I got them from google.com
Answer:
a) W = 40 J
b) -40 J
C) 62.5 J
Explanation:
Given data:
mass of particle is 5 kg
force equation is given as fx = 2x + 14
where fx force in newton
Fdx = (2x + 4)dx
integrated with respect to x gives
evaluated from 1.0 to 5.0 m:
W = 40 J
b) - 40 J (force is conservative)
c) dU = -dK (change in potential = change in kinetic)
Kf = Ki + dK = 22.5J + 40J = 62.5
D. Electrons are shared between the bromine atoms and carbon atoms
