Answer:
lastName.compareTo("Dexter")>0
Explanation:
The expression that evaluates to true if the value of variable lastName is greater than the string Dexter is; lastName.compareTo("Dexter")>0.
Answer:
Use a screw or corkscrew. Screw it into the eraser, then pull.
1)
2) 8.418
Explanation:
1)
The two components of the velocity field in x and y for the field in this problem are:
The x-component and y-component of the acceleration field can be found using the following equations:
The derivatives in this problem are:
Substituting, we find:
And
2)
In this part of the problem, we want to find the acceleration at the point
(x,y) = (-1,5)
So we have
x = -1
y = 5
First of all, we substitute these values of x and y into the expression for the components of the acceleration field:
And so we find:
And finally, we find the magnitude of the acceleration simply by applying Pythagorean's theorem:
Answer:
Work transfer is - 97.02 KJ. It means that work is given to the system.
Heat transfer = - 97.02 KJ . It means that heat is rejected from the system.
Explanation:
Given that
m= 3 kg
P₁=2 bar
T=T₁=T₂=30 °C
T=303 K
P₂=2.5 bar
PV= Constant
This is the isothermal process .
We know that work for isothermal process given as
For air
R= 0.287 KJ/Kg.K
Now by putting the values
W= - 97.02 KJ
So the work transfer is - 97.02 KJ. It means that work is given to the system.
We know that for ideal gas internal energy is the only function of temperature.The change in internal energy ΔU
ΔU = m Cv ΔT
Here ΔT= 0
So
ΔU =0
From first law of thermodynamics
Q= ΔU +W
ΔU = 0
Q= W
Q= - 97.02 KJ
Heat transfer = - 97.02 KJ . It means that heat is rejected from the system.
Answer:
A) Linear Equation -
Linear equation has only one independent variable and when the linear equation plotted on a graph it forms a straight line. It is made up of two expressions equal to each other in a equation. Linear equation graph fits the Y= mx+a ( m=slope).
B) Laplace's equation is linear as it is a second order partial differential equation. So if we put dependent variable in differential equation it always show result in linear.
