Pepper has the same state of matter after it is mixed with water.
What is the state of matter?State of matter of any substance tells about the physical appearance or the space occupied by the atoms of that substance.
From the given option; carbon dioxide, salt and sugar are soluble in water and changes their state of matter to liquid. But pepper is hydrophobic in nature that means it is not soluble in water, so present in the original state after mixing with water.
Hence, option (c) is correct i.e. pepper has the same state.

Magnesium metal burns with a bright white flame. What conclusions can you draw about the electron transitions that can take place for a magnesium atom ?
The inference that can be made regarding the electronic transition that a magnesium atom is capable of experiencing is that the photons generated are not of a single wavelength.
What is metal?Metal is any of a group of substances with strong thermal and electrical conductivity, malleability, ductility, plus high light reflection.
The inference that can be made regarding the electronic transition that a magnesium atom is capable of experiencing is that the photons generated are not of a single wavelength, but rather are transitioned from several dissimilar levels to higher tiers, with several different wavelengths having joined to create white.
Therefore, the inference that can be made regarding the electronic transition that a magnesium atom is capable of experiencing is that the photons generated are not of a single wavelength.

7. A 1.50 x 103 kg car accelerates uniformly from rest to 10.0 m/s in 3.00 s.
a. What is the work done on the car in this time interval?
b. What is the power delivered by the engine in this time interval?
Work done = force*distance = mass*acceleration*distance
acceleration = 10/3 = 3.33 m/s^2
distance = ((0+10)/2)*3 = 15m
work done = 1500*3.33*15 = 74900 J
Power = workdone/time = 74900/3 = 25000 W
a. The work done on the car in this time interval is 75000 J.
b. And, the power delivered by the engine in this time interval is 25,000 watt.
Given that,
A 1.50 x 103 kg car accelerates uniformly from rest to 10.0 m/s in 3.00 s.Based on the above information, the calculation is as follows:
(a)
We know that
[tex]w = \frac{1}{2} \times m (v^2 - u^2)[/tex]
Here
Mass = [tex]1.50 \times 103 kg[/tex]
v= 10 m / s
u= 0 m / s
Now place it to the above formula
So, Work done is = 75000 J
(b)
[tex]Power P = W \div t\\\\= 75000 \div 3[/tex]
= 25000 Watt
Therefore the above are the answers.
