What is the energy of the photons of a laser with a frequency of 5.75 x 10^12 Hz? (Hint: Remember to round your answer to the lo
Simora [160]

Answer:

E = 3.81×10 ⁻²¹ J

Explanation:

Given data:

Frequency of photon = 5.75 ×10¹² Hz

Plancks constant = 6.626 ×10⁻³⁴ Js

Energy of photon = ?

Solution:

E = h×f

E = 6.626 ×10⁻³⁴ Js ×  5.75 ×10¹² s⁻¹

E = 38.1×10 ⁻²² J

E = 3.81×10 ⁻²¹ J

If 500 mL of liquid mercury weighs 6.53 kg, what is the mass in pounds? A) 1.44 lb B) 2960 lb C ) 14.4 lb D) 7.19 lb E) 2.96 lb
soldi70 [24.7K]

Answer:

The correct option is: C ) 14.4 lb      

Explanation:

The standard International unit of mass is kilogram, kg. Other commonly used units of mass are grams (g), tonne (t), pounds (lb).

The mass of 500 mL liquid mercury is 6.53 kg.

Since, 1 kg = 2.20462 lb ≈ 2.205 lb

Therefore, the mass of 500 mL liquid mercury in pounds = 6.53 × 2.20462 = 14.39619 lb ≈ 14.4 lb.
