The true statement about the dot plot is 1 has 4 and 0 dots.

Explanation:

after creating a Bar chart 4 is the right answer.
The highest among st all the other plots is 1 but 4 shows 3.
Taking an average from all the data points 3 comes to the right answer.
Median the central Mid-point is 3.
Mode also comes to 3.
It is skewed on the right due to the 1st one.
Skewed shows the data point either increasing or in decreasing.
There a to Bi- histograms which has two ups and downs.
The true statement has to be as Mean=Median=Mode is 3.

Does the Diesel engine have engine knock or detonation problem? Why?

Luda [366]

Explanation:

Yes Diesel engine have problem of knocking.

We know that knocking is phenomenon in which suddenly large amount of power generates this large amount of power will cause the failure of diesel engine.

Actually when one set of fuel inject inside the cylinder to burn with already compressed air (in general up to 10-15 bar) then this fuel does not burn complete and accumulate inside the cylinder.After that second set of fuel inject inside the cylinder then that one set of fuel burns with second set of fuel and produces large amount of sudden power for engine and causes the breaks in the crank or connecting rod of engine.it leads to damage the engine.

Voltage drop testing is being discussed.

Airida [17]

Answer:

Technician B only is correct

Explanation:

Voltage drop testing is a method used to find the amount of electrical resistance available in an high amperage circuit that involves connecting the leads of the meter in parallel to the circuits being tested such that disassembly is not required

In voltage drop test, the red voltmeter lead and black voltmeter lead are placed at two points on the same side of the circuit connection such that the leads are in between two positive connection or two negative connection (rather than connecting the red to the positive and the black to the negative sides of the circuit) and digital voltmeter is used for the voltage drop measurement across the lead while the connection is under load.

Therefore, Technician B only is correct

What is the instantaneous center of zero velocity? List two approaches for determining the is the instantaneous center of zero v

Lera25 [3.4K]

Explanation:

Instantaneous center:

It is the center about a body moves in planer motion.The velocity of Instantaneous center is zero and Instantaneous center can be lie out side or inside the body.About this center every particle of a body rotates.

From the diagram

Where these two lines will cut then it will the I-Center.Point A and B is moving perpendicular to the point I.

If we take three link link1,link2 and link3 then I center of these three link will be in one straight line It means that they will be co-linear.

$I_{12},I_{23},I_{31} all\ are\ co-linear.$
