In a cricket match, a ball is h metres above the ground t seconds after being struck by the cricket bat. if h = 5 t – t + 1, what is the value of when the ball comes down to the ground?

40 minutes

step-by-step explanation:

add the time and multiply by 2

5050 i think

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:
