Answer:
Technician A is correct
Explanation:
The best approach to solve the problem is that of technician A. using a fluorescent die is the easiest and most efficient way to trace leaks with unknown sources. The fluorescent die will simply illuminate the path to the leaking spot in the engine of the car, without any need for much speculations. This makes this method a sure approach.
However, Technician B's approach still has a lot of assumptions factored into the methodology, and would not work properly. It will still require the painstaking attempts trying to make guesses where the oil leak is coming from, which will lead to wastage of time and energy.
This makes Technician A have the right approach to solving the problem
Weathering the process that breaks down exposed stone and rock causing it to split apart or wear away. Different forces can cause rocks to become weathered physical weathering is caused by purely mechanical changes to the rock while chemical weathering is caused by chemical reactions
Hello,
This is true. Net force can be calculated using the equation F = ma, where f is net force, m is mass, and a is acceleration. Simply multiply mass and acceleration to obtain the net force being exerted on the object.
True
Hope this helps!
Answer:
49 m/s
Explanation:
This is the question from the document:
1. A bag dropped from a helicopter falls with an acceleration of 9.8m/s2. What is its velocity after 5s?
We can find the answer by using the equation a = (v-u) / t
Acceleration a = 9.81m/s2
initial velocity u = 0 m/s (the bag is only dropped, so there's no initial velocity already existing)
time t= 5s
final velocity v = unknown
9.8 = (v -0) / 5
v - 0 = 9.8x5
v = 49 m/s
