Zero is induced in the secondary, and the total output of the transformer consists of smoke.
Transformers only work with AC.
Hooke's Law says that F=-kx where k is the spring constant measured in N/m (newtons per meter)
Answer:
an apple falling off a tree
Explanation:
Answer:
f1/f2 =W1/W2 = 1/3
.0 f2 = 3f1
As ,
1/F= 1/f1 +1/f2
...1/40 = 1/f1 - 1/3f1
f1=> 80/3 cm
... f2 = 2f1 = 3 x 80/3 = 80 cm
