Write .00000023 in scientific notation
Vikki [24]

Answer: 2.3 x 10^-7

Explanation:

When you move the decimal to the right, you decrease the exponent. So lets count how many spots you have to move the decimal spot to get an answer between 1 and 10. I counted seven spots.

So:

2.3 *10^-^7

Calculate the work done by Kevin as he lifts 3 boxes (mass=45 KG) 57 CM high with an acceleration recorded to be 12.3 m/s^2.
anyanavicka [17]
Answer = 31.5J (rounded to 1dp)

The question wants to find the work done, where work done can be calculated in the equation:

Work done = Force x Distance

The force is not given in the question, however they give the acceleration and mass, so you can calculate the force using Newton's second law:

Force = Mass x Acceleration

First, calculate the force. The mass is 45kg for the 3 boxes and the acceleration is 12.3m/s^2.

Force = 45 x 12.3

Force = 553.5N

Now that you have the force (553.5N) and distance (57cm), substitute those values into the equation for work done.

Make sure to convert the 57cm into metres (into SI units), otherwise the answer would be wrong.

57cm = 0.057m

Work done = Force x Distance

Work done = 553.5 x 0.057

Work done = 31.5J (rounded to 1dp)
