Answer:
1.25 m/s^2
Explanation:
m = 76 kg, R = 840 N
Let a be the acceleration of teh elevator in upward direction.
By use of Newton's second law
R - mg = m a
R = m ( g + a)
840 = 76 ( 9.8 + a)
a = 1.25 m/s^2
A. scatter plot (100% positive, btw quizzes is a good tool for answers)
Positive terminal with Positive terminal. The negative terminal should be connected to the car chassis.
Answer:
Explanation:
The equation for centripetal acceleration is 
. If 
is the distance from the center of the point at the tip of the blade and 
is the distance from the center of another point in the blade, and since both points are rotating at the same angular velocity 
because both of them belong to the blade, the ratio between their centripetal accelerations will be:
Answer:
C) Both 1 and 2
Explanation:
The scan tool may include a bi-directional control that allows the technician to control the output of the alternator for testing purposes.
The Diagnostic Trouble Codes (DTCs), are used by automobile manufacturers to diagnose problems related to the vehicle.
The scan tool can also be used to monitor the output voltage of the vehicle to verify if the correct amount of voltage is supplied by the alternator.
Both Technicians A and B are correct because the steps they both take are necessary for the diagnosis of the vehicle.
