Answer:
d. f
Explanation:
Based on the principle of operation of transformer, when a.c voltage is applied at the terminal of the primary coil (input coil), an alternating magnetic flux is produced in the iron core which links the secondary coil (output coil).
Also, an alternating e.m.f of <em>the same frequency</em> as that of primary coil (input coil) <u>will be induced in the secondary coil (output coil) by mutual inductance.</u>
Thus, If the input frequency is "f" then the output frequency will be "f" (since the frequency will be the same).
The correct option is "D"
Answer:
(a) 
(b) 
Explanation:
Given data

Solution
For Part (a)
As the velocity component in direction of y is given by:

The maximum displacement is given by:

For Part (b)
To reach y=46cm =0.46m apply:

It is (C): human.
This is more like forensic sciences or biology btw.
Answer:
35.7m
Explanation:
Given parameters:
Mass of rock = 25kg
Time of fall = 2.7s
Unknown:
Height of the building = ?
Solution:
To solve this problem, we will use one of the motion equations;
S = ut +
gt²
S is the height
u is the initial velocity = 0m/s
t is the time
g is the acceleration due to gravity
S = (0 x 2.7) +
x 9.8 x 2.7² = 35.7m
