Answer:
Not right now, but thank you! :)
Explanation:
The piece of evidence which President Reagan use to logically conclude that the astronauts were aware of the dangers was the previous accident on the ground
- Former President Ronald Reagan gave a powerful speech concerning the Space Shuttle Challenger disaster which claimed the life of all crew members including a teacher.
- The shuttle’s launch was said to have been delayed at least two times before the lunch date and due to pressure from the White House, it launch on January 28, 1986.
- Due to this previous issues that happened on the ground not space, the shuttle malfunction and burst to flames and if this issues were handled before takeoff, this incident would not have happened.

A,b, c and a because of how the forms are
It is important to note that the direct of flow of the electricity current in the Linear Machine is anti-clockwise direction. The resultant effect of this is such that is stand at variance with the change in flux as force is going the right direction. See attached Image (Illustration I).
<h3>What is the magnitude of the current?</h3>
Recall that Force (f) = il xB
Given that Force (F) = 10N; and
Magnetic Field Density B = 0.5T
Hence,
10 = i x 0.2 x 0.5
[Note that Width is converted to Meters from millimeters that is 200 mmm = 0.2m]
10 = 0.1i
i = 10/0.1
i = 100A
<h3>
What is the Induced Voltage Across the metal bar?</h3>
Note that Vg = Vde + IR
Vg = 10 + 100 x 0.05
Vg = 10 + 5
Vg = 15v
<h3>
What is the final speed of the metal bar?</h3>
The final speed of the bar is given as V
Recall that Induced Voltage is VB x L
That is:
15 = V x 0.5 x 0.2;
15 = 0.1 V
make V the subject of the formula:
V = 15/0.1
V = 150m/s
<h3>
What is the status of the Machine? a motor or generator?</h3>
Given that the current being supplied is in DC hence the machine is a generator. [Vdc x i]
<h3>What is the electric power of the source?</h3>
The electric power of the source is:
Vdc x i
= 10 x 100
= 1,000 watts
