<u>Given:</u>
Time taken by the electromagnetic radiation, t = 33 fs
<u>To determine:</u>
The distance (d) travelled
<u>Explanation:</u>
Time taken = 33 fs (femtosecond)
1 fs = 10⁻¹⁵ s
Thus t = 33 *10⁻¹⁵ s
Speed of electromagnetic radiation = 3*10⁸ m/s
Distance = Speed * Time = 3*10⁸ ms-1 * 33*10⁻¹⁵ s = 99*10⁻⁷ m
Ans: distance traveled = 9.9*10⁻⁶ m
Answer:
Oxygen is more electronegative than sulphur
Explanation:
Bond angle of a molecule is related to the electronegativity of the central atom. The more electronegative the central atom is, the greater the bond angle.
As electronegativity of the central atom increases, the magnitude of bond pair- bond pair repulsion increases leading to increase in bond angle.
Hence, oxygen, being more electronegative than sulphur asserts a greater bond pair- bond pair repulsion leading to a greater bond angle in water.
True becuase the substance changed into another substance which is a example of a chemical reaction.
Answer:
Explanation:
The formula for the heat released is
q = mCΔT
Data:
m = 395 g
C = 4.184 J·°C⁻¹g⁻¹
ΔT = 55 °C
Calculations:
q = 395 × 4.184 × 55 = 91 000 J = 91 kJ
The water will absorb 
of energy.
You could do how different liquids affect plant growth. Take 3 SAME plant seeds and plant them in the SAME environment. For plant A use juice, for plant B, use milk, and for planting C, use coffee.
