Question

A man makes a late payment of his property
tax of Rs. 30,000. He is late by 45 days and
on each day he is required to pay an
additional amount of 1% as penalty but up to a
maximum penalty of 15%. If the principal
amount of property tax is less than Rs.
25,000. What is the total amount of penalty he
is required to pay?
(A) 4,500
(B) 34,500
(C) 43,500
(D) 13,500​

Answer 1

Answer:

Answer:

The frequency of radio waves of wavelength 150 m is 2 MHz.

Given:

We're given with the velocity of electromagnetic wave in free space is 3 \times {10}^{8}3×10

8

m/s. Wave length of radio waves is 150 m.

To find:

We are supposed to find out the frequency of radio waves with wave length 150m.

Solution:

Apply the concept of frequency of radio waves.

It is given by,

\implies \rm\dfrac{v}{ \lambda}⟹

λ

v

\implies \rm \dfrac{3 \times {10}^{8} }{150}⟹

150

3×10

8

\implies \rm\dfrac{3 \times {10}^{7} }{15}⟹

15

3×10

7

\implies \rm\dfrac{ {10}^{7} }{5}⟹

5

10

7

\implies \rm2 \times {10}^{6} \: Hz⟹2×10

6

Hz

\implies \rm2 \: MHz⟹2MHz

So, the final answer is:

\dag \: \boxed{ \bf{2 \: MHz}}†

2MHz
