Answer:
Acceleration of the plane, a = 5.4 g
Explanation:
It is given that,
Speed of the jet plane, v = 1890 km/h = 525 m/s
Radius of the arc, r = 5.20 km = 5200 m
The plane is moving in the circular path, the centripetal acceleration will act on it. It is given by :
We know that, the value of g is, 
So, the acceleration of the plane is 5.4 g. Hence, this is the required solution.
Answer:
V = 1280 [V]
Explanation:
To solve this problem we must use ohm's law which tells us that the voltage is equal to the product of the resistance by the current.
Therefore we have:
V = I*R
where:
V = voltage [V] (Units of volts)
I = current = 4 [amp]
R = resistance = 320 [ohms]
V = 4*320
V = 1280 [V]
Answer:b
Explanation: i took the test and b was correct
I don't understand the question your asking. can you explain more?
Answer:
e
Explanation:
An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force.
