Answer
given,
mass of paint removed from the airline = 100 Kg
a) altitude of the airplane = 12000 m
energy saved to not to lift the plane = ?
U = m g h
U = 100 x 9.8 x 12000
U = 117.6 x 10⁵ J
U = 1.18 x 10⁷ J
b) Speed of the airplane = 250 m/s
U =31.25 x 10⁵ J
U = 3.125 x 10⁶ J
Answer:
In my opinion is Sally
Explanation:
It depend on your opinion,✨
Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion. If it gains one or more electrons, it now carries a net negative charge, and is thus "anionic."
Step by step solution :
standard deviation is given by :
where, is standard deviation
is mean of given data
n is number of observations
From the above data,
Now, if , then
If , then
if , then
If , then
If , then
so,
No, Joe's value does not agree with the accepted value of 25.9 seconds. This shows a lots of errors.
Answer:
Vd = 0.022 (V)
Explanation:
What we have as voltage drop is the difference between the voltage at source level (terminals) and the voltage at the terminal of electrical load ( in this case the toaster oven) that difference occures as consequence of the normal distributed resistance of conductor. But the voltage at the terminal of the electric load have to be measure between the two wires at the end of the circuit.
Therefore the voltage drop is = I*R = 11 (A) * 0,002 Ω = 0.022 (v)
