Carbon (C): 1s(H)2s(I)2p(J) What is H, I, and J equal?

Artemon [7]

Answer:

H =2; I = 2; J = 2

Explanation:

Carbon is element 6 in the Periodic Table.

Start at element 1 (H) and count from left to right until you reach element 6 (C).

You get the electron configuration

C: 1s² 2s²2p².

Thus,

H =2; I = 2; J = 2

A runner runs 4339 ft in 7.45 minutes. What is the runner's average speed in miles per hou 6.62 mi/hr O 0.110 mi/hr 6.618 mi/h e

slavikrds [6]

Answer: The average speed of the runner is 6.618 miles/hr

Explanation:

Average speed is defined as the ratio of total distance traveled to the total time taken.

To calculate the average speed of the runner, we use the equation:

$\text{Average speed}=\frac{\text{Total distance traveled}}{\text{Total time taken}}$

We are given:

Distance traveled = 4339 ft

Time taken = 7.45 mins

Putting values in above equation, we get:

$\text{Average speed of runner}=\frac{4330ft}{7.45min}=582.42ft/min$

To convert the speed into miles per hour, we use the conversion factors:

1 mile = 5280 ft

1 hr = 60 mins

Converting the speed into miles per hour, we get:

$\Rightarrow \frac{528.42ft}{min}\times (\frac{1miles}{5280ft})\times (\frac{60min}{1hr})\\\\\Rightarrow 6.618mil/hr$

Hence, the average speed of the runner is 6.618 miles/hr
