Answer:
the distance between the lawyer's home and her office is 124 miles
Explanation:
given information:
first lets assume that
x-axis (west = positive, east = negative)
y-axis (north = positive, south = negative)
thus,
distance of the house = (-88,18)
distance of the office = (13, -54)
thus, the distance between the lawyer's home and her office
R = √(x₂ - x₁)² + (y₂ - y₁)²
= √(13 - (-88))² + (-54 -18)²
= 124 miles
I think the question when stated clearly is: What factors does the coefficient of volume expansions depends on? I think that is volume expansion because of the word cubic. In physics, some materials expand in length and in volume, when temperature changes occur. Each kind of material has their empirical values of coefficient of volume expansion in units of m³/°C. So, the obvious factor here is temperature. Generally, as the temperature increases, the volume expands because the molecules move more rapidly occupying more space. For gases, the factor of pressure is also important. But for incompressible objects like solids and liquids, it does not depend on pressure effects anymore.
Explanation:
Work done by gravity is given by the formula,
W = ......... (1)
It is known that when levels are same then height of the liquid is as follows.
h = ......... (2)
Putting value of equation (2) in equation (1) the overall formula will be as follows.
W =
=
= 0.689 J
Thus, we can conclude that the work done by the gravitational force in equalizing the levels when the two vessels are connected is 0.689 J.
The solution to the problem is as follows:
Given Ff α v^2
<span>
=>Ff = kv^2 </span>
=>800 = k x (20)^2
=>k = 2
<span>
2nd condition:- </span>
=>Ff = kv^2
=>Ff = 2 x (40)^2
=>Ff = 3200 N
<span>
At constant speed=>a = 0=>F(net) = 0 </span>
<span>
By F(net) = F(applied) - F(friction) </span>
=>Fa = Ff = 3200 N
<span>
Thus by P = Fv </span>
=>P = 3200 x 40
<span>=>P = 128000 Watt OR 128 kW
I hope my answer has come to your help. God bless and have a nice day ahead!
