Answer:
5N
Explanation:
Given parameters:
Original length = 22cm
Spring constant, K = 50N/m
New length = 32cm
Unknown
Force applied = ?
Solution:
The force applied on a spring can be derived using the expression below;
Force = KE
k is the spring constant
E is the extension
extension = new length - original length
extension = 32cm - 22cm = 10cm
convert the extension from cm to m;
100cm = 1m;
10cm will give 0.1m
So;
Force = 50N/m x 0.1m = 5N
No, light does not have mass because a photon does not way anything.
Answer:
a) W=85.225 kW
b) 
Explanation:
First, consider the energy balance for the compressor: The energy that enters to the system (W and enthalpy of the feed flow) is equal to the energy that goes out from it (Heat Q and enthalpy of the exit flow):
Consider the enthalpy data from van Wylen 6th edition, Table B.2.2. According to that, 
, 
So, the power input to the compressor is:
b) The differential entropy change dS for a reversible heat transfer dQ at a temperature T is:
This equation can be integrated if the heat transfer surface temperature remains constant, which is the case, giving as a result:
Answer: Neighbour
Explanation: Taken perspective from the given clues:
The Neighbor walks to work
The Handyman rides a bike
The Cook rides a motorcycle
The Maid drives a car
The Nephew has a dog
If we assume that the handyman delivered the iPad in the mailbox, then
The direction of the cook, Nephew and his dog are perpendicular to the direction of the bike of the handyman. So, it can't be the cook, Nephew and the maid.
The two suspects are the handyman and the neighbour.
If the handyman actually dropped the iPad and left, then, the neighbour should be the culprit.
