tigry1 [53]

Answer:

Kinetic energy = 0.25 J

Explanation:

The question is "If we take container one as a reference and apply 5 grams of ink and the water moves at a speed of 10m / s, what would the kinetic energy of the solution be?"

We have,

Mass of ink, m = 5 grams = 0.005 kg

Speed of water, v = 10 m/s

We need to find the kinetic energy of the solution of water and ink. Kinetic energy is associated with the motion of an object. Its formula is given by :

K=\dfrac{1}{2}mv^2\\\\K=\dfrac{1}{2}\times 0.005\times (10)^2\\\\K=0.25\ J

So, the kinetic energy of the solution is 0.25 Joules.

You and a friend both leave the same restaurant to drive home. You are heading directly west at 30 miles per hour and he or she
steposvetlana [31]

Answer:

\frac{dAB}{dt} = = 50 miles/ hour

Explanation:

let A represent me and B represent my friend

A speed\frac{dOA}{dt}=30 m/hr toward west

B speed\frac{dOB}{dt} =40 m/hr toward south

after 1/2 hr

total distance cover by A =1/2 * 30 miles = 15 miles

total distance by B = 1/2*40 miles = 20 miles

now from figure

AB = \sqrt{(15^2+20^2)} = 25 miles

AB^2 =OA^2+ OB^2

Differentiate above equation

2AB\frac{dAB}{dt} = 2OA\frac{dOA}{dt} +2OB\frac{dOB}{dt}

25*\frac{dAB}{dt} = 15*30 +20*40

\frac{dAB}{dt} = \frac{1250}{25}

\frac{dAB}{dt} = = 50 miles/ hour

Write the sequence of filling electrons in the subshell in order of increasing energy.​
tankabanditka [31]

Answer:

In a way of energy “1s” subsell contains most energy. because 1 s subsell contains the electrons of K orbital which is nearest from the nucleus. so the order of energy will be 1s>2s>2p> 3s> 3p> 4s> 3d> 4p> 5s> 4d> 5p> 6s> 4f> 5d> 6p> 7s and the increasing order of thair energies will be- 4s <3d<4p<5s<4d<5p<6s<4f.
