If a bullet travels at 551.0 m/s, what is its speed in miles per hour?
77julia77 [94]
<span>First, convert meters into feet. One meter = 3.28 feet. Next, convert meters per second to feet per second. 551.0 m/s = 1,807.28 ft/sec. Now using the knowledge that 5280 ft = 1 mile and there are 3600 seconds in an hour; convert 1,807.28 ft/sec into miles per hour. The final answer to the question is 1,232.24 miles per hour.</span>

Answer:

-5.39\times10^{33} J

Explanation:

Potential energy =

-\frac{GMm}{r}\\=-\frac{6.67\times10^{-11}\times1.99\times10^{30}\times5.97\times10^{24}}{147/1\times10^{9}}\\=-5.39\times10^{33} J

In an evaporation of water experiment, the initial mass of water in a beaker was 10.5775 +/- 0.0002 g. After some time, the mass
muminat

Answer:

Explanation:

The theory of  propagation of error in case of addition and subtraction states that maximum errors are added in absolute terms in both the operation of addition and subtraction . So in this case the subtracted value will be

10.5775 - 10.3005

= .2770 g

errors will be added ie in subtracted value we can find error to the tune of

.0002 + .0002 = .0004 g

So the subtracted value will be written as

.2770 ± .0004
