Find the simple interest of Rs 20000 for 5 years at 10% per annum? Also, at what time will Rs. 50000 earn the same amount of interest per annum?

yes

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

-1   1/6.   you dont subtract the denominators
