Answer:
1- t^3
2- t^2
3- t1
Explanation:
The acceleration produced in a body, while travelling in a circular motion, due to change in direction of motion is called centripetal acceleration. The formula of the centripetal acceleration is as follows:
ac = v²/r
where,
ac = centripetal acceleration
v = speed
r = radius
for a constant radius the centripetal acceleration will be directly proportional to the speed of object. The speed of pendulum will be lowest at t1 due to zero speed initially. Then the speed will increase gradually having greater speed at t^2 and the highest speed and centripetal acceleration at t^3. Therefore, the three instants in tie can be written in following order from greatest centripetal acceleration to lowest:
<u>1- t^3</u>
<u>2- t^2</u>
<u>3- t1</u>
Power = (voltage) x (current)
Power = (120) x (8) = 960 watts = <em>0.960 kilowatt</em>

Explanation:
a rock formed from particles that are deposited and lithified are sedimentary.
rocks formed from cooling and hardening magma or lava is igneous.
a rock formed when an already existing rock is subjected to extreme heat and pressure is metamorphic.
<h2>Answer:</h2>
<u>The statement is </u><u>False</u>
<h2>Explanation:</h2>
Contaminated rags may contain plastic and other materials that cannot be defused in soil and they remain there for a long period of time. Another reason to avoid disposal of contaminated material in earth is that it may also contain toxic materials which may result into land pollution. So it is not recommended to dispose contaminated rags in landfills.
