Answer:

No

Explanation:

There is no limit to how fast the universe can expand, says physicist Charles Bennett of Johns Hopkins University. Einstein's theory that nothing can travel faster than the speed of light in a vacuum still holds true, because space itself is stretching, and space is nothing.

When non-metric units were used in the United Kingdom, a unit of mass called the pound-mass (lbm) was employed, where 1lbm=0.453
Drupady [299]

Answer:

a) 0.022%

b) 10014.32 lb

Explanation:

a) Percentage uncertainty would be

0.0001\times \frac{100}{0.4539}=0.022%

Percent uncertainty is 0.022%

b) For 1 kg uncertainty mass in kg would be

\frac{1}{0.022}\times {100}=4545.5\ kg

Mass in pounds would be

\frac{4545.5}{0.4539}=10014.32\ lb

Mass in pound-mass is 10014.32 lb

She leaves her campsite and runs north for 10 miles turns east and runs 8 miles then turns south and runs 2 miles.whats her dist
Mama L [17]

The distance is 20 miles

Explanation:

Definitions:

  • Distance is the total length of the path covered by an object during its motion, regardless of the direction of its motion
  • Displacement is the shortest distance between the initial and final position of the motion, so it also takes into account the direction of motion

In this problem, we want to know the distance covered by the woman. The motion consists of the following parts:

d_1 = 10 miles north

d_2 = 8 miles east

d_3 = 2 miles south

To find the distance, we just have to add the length of each path, ignoring the direction. Therefore:

d=d_1 + d_2 + d_3 = 10+8+2 = 20 miles
