Enough hate to cause an extremely low pressure field around the water so it evaporates BELOW it's normal boiling point.

The efficiency of the constuction is 9.0
Explanation:
Answer:
largest lead = 3 m
Explanation:
Basically, this problem is about what is the largest possible distance anchorman for team B can have over the anchorman for team A when the final leg started that anchorman for team A won the race. This show that anchorman for team A must have higher velocity than anchorman for team B to won the race as at the starting of final leg team B runner leads the team A runner.
So, first we need to calculate the velocities of both the anchorman
given data:
Distance = d = 100 m
Time arrival for A = 9.8 s
Time arrival for B = 10.1 s
Velocity of anchorman A = D / Time arrival for A
=100/ 9.8 = 10.2 m/s
Velocity of anchorman B = D / Time arrival for B
=100/10.1 = 9.9 m/s
As speed of anchorman A is greater than anchorman B. So, anchorman A complete the race first than anchorman B. So, anchorman B covered lower distance than anchorman A. So to calculate the covered distance during time 9.8 s for B runner, we use
d = vt
= 9.9 x 9.8 = 97 m
So, during the same time interval, anchorman A covered 100 m distance which is greater than anchorman B distance which is 97 m.
largest lead = 100 - 97 = 3 m
So if his lead no more than 3 m anchorman A win the race.

Explanation:
Given
Current in two wires


Magnetic Force per unit length is given by

where 
r=radial distance between wires

Force on two wires will be equal in magnitudes but opposite in direction so Force on wire 1 duet o wire 2

Answer:
Explanation:
The energy for an isothermal expansion can be computed as:
--- (1)
However, we are being told that the volume of the gas is twice itself when undergoing adiabatic expansion. This implies that:

Equation (1) can be written as:

Also, in a Carnot engine, the efficiency can be computed as:


In addition to that, for any heat engine, the efficiency e =
relating the above two equations together, we have:

Making the work done (W) the subject:

From equation (1):


If we consider the adiabatic expansion as well:
= constant
i.e.

From ideal gas PV = nRT
we can have:


From the question, let us recall aw we are being informed that:
If the volumes changes by a factor = 5.7
Then, it implies that:

∴

In an ideal monoatomic gas 
As such:


Replacing the value of
into equation 

From in the question:
W = 930 J and the moles = 1.90
using 8.314 as constant
Then:




From
