In April​, ​Seattle's daily high temperature has a mean of 59degreesF and a standard deviation of 7degreesF. The formula to conv

ert degrees Fahrenheit degreesF to degrees Celsius degreesC ​is: Superscript o Baseline Upper C equals five ninths (Superscript o Baseline Upper F minus 32 )Use this information to answer the following questions. Compute the mean of​ Seattle's daily high temperature in degrees Celsius degreesC. The mean of the daily high temperature in degrees Celcius​ = nothingdegreesC ​(Round your response to three decimal place.​)

Answer:

T = 15 \pm 3.89 ^oC

Explanation:

As we know that the equation to convert Fahrenheit to Celcius we have

C = \frac{5}{9}(F - 32)

so we have

T = 59 ^o F

so we have

T = \frac{5}{9}(59 - 32)

T = 15^o C

now the uncertainty in temperature is given as

\Delta C = \frac{5}{9}(\Delta F)

so we have

\Delta T = \frac{5}{9}(7)

\Delta T = 3.89 ^o C

so the temperature is given as

T = 15 \pm 3.89 ^oC

For this case we have that by definition, physical power refers to the amount of work done for a unit of time.

So:

P = \frac {W} {t}

Where:

W: It's the work

t: It's time

The power units are in \frac {Joules} {s} = Watts

So, according to the problem data we have:

P = 100W\\t = 120s

Clearing the work of the formula:

W = P * t\\W = 100 * 120 = 1200

Thus, the work is 1200 joules.

Option C

While riding a bike down a steep hill at 9ms you skid to a stop in 3.2 seconds. How far did the bike slide? Assume uniform accel
castortr0y [4]

Answer:

24.30 m

Explanation:

v(final)=v(initial)+at

0 m/s= 9 m/s +a(3.2s)

a=-2.81 m/s^2

delta x= vt+ (1/2)at^2

=(9 m/s * 3.2 s)+ (.5* -2.81 m/s^2 * 3.2s)

=24.30 m

Vsevolod [243]

Answer and explanation:

A.

Muon travelled straight down towards the earth. Therefore the tree moves up in the rest frame of muon (option a)

B.

In muon rest frame it travels Zero meters

C.

Distance, d = Velocity, v * Time, s

where, v = 0.9c = 0.9 \times 8 \times 10^8 , s = 2.2 \mu s

d = 0.9 \times 3 \times 10^8 \times 2.2 \times 10^{-6}\\\\d = 594m

D.

Distance from the top of the mountain to the tree is the same as the distance travelled by the tree in the muons rest frame

that is same as in part C which is 594m

E.

Using lorentz contraction

In the rest frame of someone standing on the mountain

the distance is given by

d' = \frac{d}{\gamma} = d\sqrt{1 - \frac{v^2}{c^2}}, where, \frac{1}{\gamma}= \sqrt{1 - \frac{v^2}{c^2}}

d' = 594\sqrt{1 - \frac{(0.9c)^2}{c^2}}

d' = 594\sqrt{1 - 0.81}

d' = 594 \times 0.4359

d' = 258.92m

F.

in the rest frame of someone standing on the mountain,

muon moves straight down
