write two differences between practical machine and ideal machine
Answer:
Ideal machines are said to have parts which are weightless , frictionless and strings if any are inextensible. Practical machines have parts which have weights, friction and it causes some loss of work done. So these are the differences between Ideal Machine and Practical Machines.

When you put water in the ice tray in the freezer, water becomes ice. Ice is more ordered than water. Is this a violation of Second Law of Thermodynamics
Answer:
No because the heat that moved out of the water to make ice caused an even greater disorder in the environment around it.

The distance from Atlanta to Macon is about 80 miles out of 58.5° south of east. What distance is dues east and dues south mustyou drive in order to travel from Atlanta to Macon?
Answer:
One must drive [tex]$41 \cdot 8\,miles$[/tex] north and [tex]$68 \cdot 24\,miles$[/tex] south, in order to travel from Atlanta to Macon.
Explanation:
• The distance of an object can be defined as the complete path travelled by an object.
• To find the distance, find its north component.
• For reference see the below graph:
[tex]$$\[\begin{align}& D_{south} = 80\sin \left( {58 \cdot {5^ \circ }} \right) \\& D_{north} = 80\cos \left( {58 \cdot {5^ \circ }} \right) \\\end{align}\]$$Since, $\sin \left( {58 \cdot {5^ \circ }} \right) = \cdot 853$ and $\cos \left( {58 \cdot {5^ \circ }} \right) = \cdot 5224$: therefore,$$\[\begin{align} D_{south} &= 80 \times \left( { \cdot {{853}^ \circ }} \right) \\ \Rightarrow {D_{south}} &= 68 \cdot 24\,miles \\ \end{align}\]$$[/tex]
And
[tex]$$\[\begin{align} D_{north}& = 80 \times \cdot 5224 \\ \Rightarrow D_{north}& = 41 \cdot 8\,miles \\ \end{align}\]$$[/tex]
• Hence, one must drive [tex]$41 \cdot 8\,miles$[/tex] north and [tex]$68 \cdot 24\,miles$[/tex] south, in order to travel from Atlanta to Macon.

Which of the following is certain to change as a ball
accelerates?
A mass of the ball
B inertia of the ball
C velocity of the ball
Dforce acting on the ball occasionally
Answer:
C. Velocity of the ball
Explanation:
This is because as the acceleration of the ball increases, there will be an increase in the velocity rate and decrease in the time.

The temperature at which water leaves the boiler is?
Answer:
The average setting for a gas-powered hot water boiler is 180°F. This provides the appropriate level needed for most cold weather temperatures. If you can raise the temperature manually, do not set it any higher than 210°F (which is often the limit), and try to remain down at 190°F if you need the extra heat.
If mass is measured in kg and acceleration is measured in m/s^2, what units would force be measured in? This unit is also know as a newton (N).
Using Newtons second law
[tex]\\ \sf\longmapsto Force=Mass\times Acceleration[/tex]
[tex]\\ \sf\longmapsto Force=kgm/s^2[/tex]
[tex]\\ \sf\longmapsto Force=Newton(N)[/tex]

Volume of wood is 68-50 = 18 cm³
Explanation:
Hope it helps youWhich of the following best represents R=A+B ?
A)
B)
C)
Answer:
C
Explanation:
Options A and B are not even pointing in the direction as the vectors in the question so they shouldn't even be considered.
Option C looks like the closes since vectors A and B are pointing in a similar direction (negative x-axis)
The best representation for the resultant vector representing the resultant R=A+B would be option C because the result is represented by the closing side of the triangle, therefore the correct answer would be C.
What is a vector quantity?The quantities that contain the magnitude of the quantities along with the direction are known as the vector quantities.
Examples of vector quantities are displacement, velocity acceleration, force, etc.
As given in the problem we have to find out the resultant vector from the sum of vector A and vector B,
The resultant of the vector can be calculated with the help of the triangle law of the vector addition in which the sum is given by the closing side of the triangle.
Thus, the correct answer is option C.

The primary coil of a transformer has 2650 volts and a current of 66 A. What current is in the secondary coil if it has 4700
volts?*
12 =
A
*Round your answer to the nearest thousandth if necessary.
Answer:
117.06 A
Explanation:
V = IR
2650 = 66(R)
2650/66 = R
40.15 = R
V = IR
4700 = I(40.15)
4700/40.15 = I
117.06 = I
a car is traveling north. can its acceleration vector ever Point South? explain
When a car is traveling north, its acceleration vector can point south when it is slowing down.
A vector quantity has both magnitude and direction. The direction of a vector is always shown by the direction to which the arrow points.
If the car is travelling north, the direction of the acceleration vector will continue to point northwards.
However, when the car slows down, the direction of the accelerating vector will now point southwards.

What would make oppositely charged objects attract each other more?
o increasing the positive charge of the positively charged object and increasing the negative charge of the negatively charged object
O decreasing the positive charge of the positively charged object and decreasing the negative charge of the negatively charged object
O increasing the distance between the positively charged object and the negatively charged object
O maintaining the distance between the positively charged object and the negatively charged object
Answer:
a: increasing the positive charge of the positively charged object and increasing the negative charge of the negatively charged object
Explanation:
The oppositely charged objects attract each other more is option a. It increased the positive charge and the negative charge.
The Attraction of the oppositely charged:At the time when the oppositely charged objects are attracted to each other more so here the positive charge should be increased with respect to the positive charge object and the negative charge is increased with respect to the negative charge object
Hence, the first option is correct.
