Answer:
E = 3.6×10⁻¹⁹ J
Explanation:
Given data:
Wavelength = 550 nm (550 ×10⁻⁹ nm)
Energy of wave = ?
Solution:
Formula:
E = h c/λ
c = 3×10⁸ m/s
h = 6.63×10⁻³⁴ Js
Now we will put the values in formula.
E = 6.63×10⁻³⁴ Js × 3×10⁸ m/s /550 ×10⁻⁹ nm
E = 19.89×10⁻²⁶ J.m /550 ×10⁻⁹ nm
E = 0.036×10⁻¹⁷ J
Dry more clothes at the same time so that there is less room for electric forces.
1.389
P = m / V
m = 1250
V = 4x9x25 = 900
1250/900 = 1.388889
B) is the correct answer
FALSE.
The right answer is false. There are three different groups of phylum for worms.
