Answer:
Linear expansivity is a property specific to a material and hence is constant.
Explanation:
Linear expansivity of the material will be constant irrespective of the shape and size of the material because it is a specific property.
It is a tendency of a material to expand in response to the increase in temperature.
The mathematical expression is given as:
where:
= change in temperature
L= initial length of the specimen
= linear expansivity
=change in length
Answer:
The desk will move to the left.
Explanation:
Since Manuel is exerting a force of 10 N to the right, and Lynn is exerting a force of 15 N to the left, it means that Lynn is exerting a force of 5 N more than Manuel, meaning that the desk will move to the left, the direction Lynn is pushing it too.

Answer:
It takes <u>6.67 second</u> to finish the task by the machine.
Explanation:
Given that,
Work done by the machine (w) = 500J
Power generated by the machine (P) = 75 watt
The dimension of power is energy divided by time. The "SI unit" of "power" is the "watt" (W), which is equal to "one joule per second"
.
Calculate the time for the given work and power.
Time = 6.67 second
6.67 second long did it take to complete its task.
