For this case we must find a reasonable estimate, in scientific notation, for a wavelength given by:

0.000000492 meters

If we roll the decimal seven spaces to the right we have:

4.92 * 10 ^ {- 7}\ m

The exponent is negative.

The expression can be written as:

5 * 10 ^ {- 7}\ m

Answer:

Option C

if the kinetic energy of an aeroplane moving at a velocity of 100m/s is 200j ,what is the mass of the aeroplane
Black_prince [1.1K]

Answer:

<u>0.04kg</u>

Step-by-step explanation:

Kinetic energy Formula: eK=0.5×m×v²

to work out mass

we can rearrange the formula and make it:

~m=eK÷(0.5×v²)

now insert the missing digits into the formula:

m=200÷(0.5×100²)

work it out, and you get your answer

m=0.04kg

Hopefully this helped-have a good day)
