Answer:

Inorganic.

Explanation:

The chemical change which describes the reactions of elements and compounds that, in general, do not involve carbon and typically take place in laboratories or industries is inorganic.

In Chemistry, an inorganic chemical reaction can be defined as a type of chemical reaction that occurs without a carbon-hydrogen bond.

On the other hand, organic chemistry deals with reaction that occur in the presence of carbon-hydrogen bonds such as hydrocarbons.

Find the length of the smallest standing wave that can be formed with light having frequency 600 THz
Reika [66]

Answer:

L=2.5*10^-^7m

Explanation:

From the question we are told that

Frequency of light  f= 600 THz

Generally the equation for wave is mathematically given as

\lambda=\frac{c}{\gamma}

Where

1THz=10^1^2

\lambda=\frac{3*10^8}{600*10^1^2}

\lambda=0.5*10^-^6m

Generally the equation for a fundamental Frequency  is mathematically given as

L=\frac{\lambda}{2}

L=\frac{0.5*10^-^6}{2}

Therefore the length of the smallest standing wave

L=2.5*10^-^7m

What is the average velocity of a car if it travels from position 25m to a position of -7m in 34 seconds?
zubka84 [21]

Answer:

vp = 0.94 m/s

Explanation

Formula

Vp = position/ time

position: Initial position - Final position

Position = 25 m - (-7 m) = 25 m + 7 m = 32 m

Then

Vp = 32 m / 34 seconds

Vp = 0.94 m/s

A 0.10-kg ball, traveling horizontally at 25 m/s, strikes a wall and rebounds at 19 m/s. What is the 7) magnitude of the change
IRISSAK [1]

Answer:

Change in momentum will be -4.4 kgm/sec

So option (A) is correct option

Explanation:

Mass of the ball is given m = 0.10 kg

Initial velocity of ball v_1=25m/sec

And velocity after rebound v_2=-19m/sec

We have to find the change in momentum

So change in momentum is equal to =m(v_2-v_1)=0.1\times (-19-25)=-4.4kgm/sec ( here negative sign shows only direction )

So option (A) will be correct answer
