A quarter is approximately 0.07 inches thick. A dollar bill is approximately 4.3 × 10-3 inches thick.

nlexa [21]

Answer:

m = 6.57 and n = -2

Step-by-step explanation:

To answer this question you will covert the thickness of a dollar to standard notation and then compare the two values.

0.07 =compared to 0.0043 = 0.0657

0.0657 = 6.57 x 10^-2

A quarter is thicker than a dollar by 6.57 x 10^-2.

Pierre lifts a 60-kg crate onto a truck bed 1 m high in 3 s. Marie lifts twenty-four 2.5-kg boxes onto the same truck bed in a t

lys-0071 [83]

Answer:

Pierre operates at a greater power level than Marie.

Marie and Pierre do the same amount of work

Step-by-step explanation:

Mass of crate=60kg

Height of truck bed=1 m

Time=3s

Pierre's work done= $60\times 1\times 9.8=588J$

Using formula Work done=mgh

Where m=mass of object

g=Acceleration due to gravity=9.8 $m/s^2$

Power= $\frac{w}{t}$

Using the formula

Pierre's power= $\frac{588}{3}=196watt$

Mass of box=2.5Kg

Total number of boxes=24

Total mass of boxes= $2.5\times 24=60kg$

Time=2 min= $2\times 60=120s$

1 min=60 s

Marie;s work done= $60\times 1\times 9.8=588J$

Marie's power= $\frac{588}{120}=4.9watt$

Pierre operates at a greater power level than Marie.

Marie and Pierre do the same amount of work
