Answer:
E = 1.33 MeV = 2.13 x 
J
v = wavelength = E / h = 2.13 x / 6.626 x 
= 3.2 x 
m
f = frequency = c / 3.2 x m = 3 x 
/ 3.2 x = 9.375 x Hz
Answer:Sunlight
Explanation:
Sunlight is a physical factor that really determine the amount of plant life available in an ecosystem. Plants depend on sunlight to produce their own food via photosynthesis. Hence in the absence of sunlight, the amount of plant life will drastically reduce in a given ecosystem. Sunlight is indispensable for plant growth.
Answer:
Explanation:
a) 1 troy ounce is equal to 31.103 g
2.41 troy ounce is equal to 2.41 x 31.103 g
= 74.958 g
b) 1 ounce = 1 / 16 lb = 1/16 x 453.6 g = 28.35 g.
1 troy ounce = 31.103 g
so 1 troy ounce is heavier than 1 ounce.
