Answer:
<em>Yes, work has been done on the mud.</em>
<em></em>
Explanation:
Work is done on a body, when a force is applied on the body to move it through a certain distance. In the case of the mud, the tire exerts a centripetal force on the mud. The centripetal force moves the mud along a path that follows the circle formed by the tire in one revolution of the tire. The total distance traveled is the circumference of the circle formed. <em>The work done on the mud is therefore the product of the centripetal force on the mud from the tire, and the circumference of the circle formed by the tire, usually expressed in radian.</em>
Answer:
This system uses angular momentum and torque to do work on objects, typically against the force of gravity. The wheel and axle simple machine is closely related to gears.
B. Accelerator mass spectrometer
<h2>
Answer: 2 lights (in parallel)</h2>
Explanation:
When light bulbs are connected in series the total voltage will be:
(1)
This means the <u>total voltage will be distributed among each of the bulbs</u> in series, therefore the luminosity will be also divided among the bulbs.
When lights are connected in parallel the total voltage will be:
(2)
This means the <u>total voltage will be the same for each bulbs</u> in parallel, therefore the luminosity will be the same.
Now, if we combine this two types of connections, as in this problem with 11 lights in series, which are also in series with 2 lights in parallel; the 2 lights in parallel will be brighter than the 11 lights in series.
Answer:
Explanation:
As we know that the equation to convert Fahrenheit to Celcius we have
so we have
so we have
now the uncertainty in temperature is given as
so we have
so the temperature is given as
