Answer:
Frequency = 4.74 × 10¹⁴ Hz
Explanation:
Given data:
Wavelength of light = 633 nm (633 ×10⁻⁹ m)
Frequency of light = ?
Solution:
Speed of light = wavelength × frequency
Frequency = Speed of light / wavelength
Speed of light = 3 × 10⁸ m/s
Frequency = 3 × 10⁸ m/s / 633 ×10⁻⁹ m
Frequency = 0.00474 × 10¹⁷ s⁻¹
Frequency = 4.74 × 10¹⁴s⁻¹
s⁻¹ = Hz
Frequency = 4.74 × 10¹⁴ Hz
Answer:
part 1 is from the article
Explanation:
Density (p) is defined as the mass (m) per unit volume (v) or:
p = m/v
Using this relationship, the volume is:
v = m/p
Using the given values of mass of 80 grams and density of 8 g/cm3, the sample volume is:
v = 80 grams/8 grams/cm3
v = 10 cm3
The final answer is 10 cm3.
Answer:
The system will try to balance the change by shifting toward the exothermic reaction, and the rate of the forward reaction will increase.
Explanation:
To balance the external cooling system has to give out heat so exothermic reaction will occur .
