Explanation:
In order to compute correctly the sum of the two terms, we have to rewrite one of them such that they have the same exponent.
The two terms are:


For instance, we can re-write the second term such as it also has a power
. In order to do that, we have to move the decimal point one place to the left, therefore:

At this point, the two numbers have the same exponent, so we can just add them together by adding the bases and keeping the same exponent, -2:

The magnetizing current in a transformer is rich in 3rd harmonic. This is because harmonics are AC voltages and currents with frequencies that are generally higher.
I believe the answer is D
Hope this helps :)
Answer:
a) 13.59 m/s²
b) 67.95 m/s
c) 169.875 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
m = Mass
Force

Acceleration of the jet is 13.59 m/s²

Velocity attained at 5 seconds is 67.95 m/s

Distance traveled in the 5 seconds is 169.875 m
Balance. acids and bases counteract each other on the PH scale.
