By definition for an elastic shock, we have that if the second particle is at rest, then the final velocity of the first particle will be given by vf1 = ((m1-m2) * vi1) / (m1 + m2). Then, substituting the values: vf1 = ((0.1-0.3) * 10) / (0.1 + 0.4) = - 5m / s.
Answer:
No.
Explanation:
A transformer requires AC to work. A battery delivers DC only.
FIrst, just write down what we know :)
1. 1 mile = 1.6klm
2. There are 3600 seconds in an hr (<em>60s x 60mins = 3600</em>).
Now to get to <em>meters per second</em> (m/s) we need to first work out <em>meters per </em><em>hr</em> (simply convert miles to klm and then multiply by 1000)<em>.</em>
60 x 1.6 = 96 klm/hr x 1000 = 96,000 meters/hr
Now we know this, we can simply divide the meters per hr by <em>how many seconds there are in 1hr</em> to get meters per second:
96000 / 3600 = 26.67m/s
It’s an assortment of compound molecules
Answer:
<h2>28,000 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 800 × 35
We have the final answer as
<h3>28,000 N</h3>
Hope this helps you
