Divide CFU of Dilution. Divide the CFU of the dilution (the number of colonies you counted) by the result from step 4. For this example, you work out 46 ÷ 1/1000, which is the same as 46 x 1,000. The result is 46,000 CFU in the original sample.

What type of electron is available to form bonds?
emmasim [6.3K]

Answer:

Valence electrons

Explanation:

The valence electrons are found in the outermost shell of an atom. They are the most loosely held electrons found within an atom. These valence electrons are involved and are used to form bonds when atoms combines together.

The energy required to remove these loosely held electrons is relatively low compared to electrons located in the inner orbitals. This is why when atoms combines, they use the outermost electrons to form bonds and mimic stable atoms like those of the noble gases.

A car was driving at a speed of 10 m/s. In 3 seconds, it accelerated to a speed of 50 m/s. Calculate the car's acceleration.
Thepotemich [5.8K]

Answer:

\boxed {\boxed {\sf 13.3 \ m/s^2}}

Explanation:

Acceleration is the rate of change of velocity with respect to time. It is the change in velocity over the change in time, and it is calculated using the following formula.

a= \frac{ v_f-v_i}{t}

The car starts at a speed of 10 meters per second, then it accelerates to a speed of 50 meters per second. It achieves this acceleration in 3 seconds.

  • v_f= 50 m/s
  • v_i= 10 m/s
  • t= 3 s

Substitute the values into the formula.

a= \frac{50 \ m/s - 10 \ m/s}{3 \ s}

Solve the numerator.

  • 50 m/s -10 m/s= 40 m/s

a= \frac{40 \ m/s}{3 \ s}

Divide.

a= 13.3333333 \ m/s/s

a \approx 13.3 \ m/s^2

The car's acceleration is approximately <u>13.3 meters per second squared.</u>
