Answer:
<h3>The answer is 1.71 %</h3>
Explanation:
The percentage error of a certain measurement can be found by using the formula
![P(\%) = \frac{error}{actual \: \: number} \times 100\% \\](https://tex.z-dn.net/?f=P%28%5C%25%29%20%3D%20%20%5Cfrac%7Berror%7D%7Bactual%20%5C%3A%20%20%5C%3A%20number%7D%20%20%5Ctimes%20100%5C%25%20%5C%5C%20)
From the question
actual mass = 200 g
error = 200 - 196.59 = 3.41
We have
![p(\%) = \frac{3.41}{200} \times 100 \\ = 1.705](https://tex.z-dn.net/?f=p%28%5C%25%29%20%3D%20%20%5Cfrac%7B3.41%7D%7B200%7D%20%20%5Ctimes%20100%20%5C%5C%20%20%3D%201.705)
We have the final answer as
<h3>1.71 %</h3>

Answer:
Energy emitted by photon = 45.06 × 10−32 J
Explanation:
Energy of photon is given by E = hf
where
h is the Planck's constant whose value is 6.626×10−34J⋅s
f is the frequency of photon
________________________________________
given that
f = 6.8 x 104 Hz
1 HZ = 1 s^-1
E = 6.626×10−34J⋅s * 6.8 x 10^4 Hz
E = 45.06 × 10−32 J
Thus,
Energy emitted by photon is 45.06 × 10−32 J

A bright feild is most commonly used
<span>No, the denisty of any substance/liquid is always constant, no matter what the volume or mass is. Once the mass g/ volume mL is taken into consideration, the effect of the ammount of liquid given is canceled out. Thus, no matter what your sample is, the density of water will always be 1 g/mL</span>
