Answer:
It gets attracted
Explanation:
Materials that attracts magnet gets attracted to the magnet at both the North and South Pole. This can be compared to how neutral objects also gets attracted to the positively and negatively charged rod through the force of polarisation.
Answer:
The power required to move each bale is 30 lbf.ft/sec.
Explanation:
F= 40lbf * sin (30º)
F=20lbf
P= F*v
P=20 lbf * 1.5 ft/sec
P= 30 lbf.ft/sec
Weight = mass × gravity
Earth:
W = 70 × 9.8
= 686 Newtons
Answer:
“Just believe in yourself. Even if you don’t pretend that you do and, and some point, you will.”
Explanation:
The correct equation for the acceleration is a = (v-u)t. Option D is correct.
<h3 /><h3>What is the first equation of motion?</h3>
The acceleration can be defined as the ratio of change in velocity to time. As given in the question,
The final velocity,
Where,
v - final velocity
u - initial velocity
a - acceleration
t - time
First, bring u with v,
Now bring the t with v-u,
So,
Therefore, the correct equation for the acceleration is a = (v-u)t.
