Answer:
5.20 to the nearest hundredth.
Step-by-step explanation:
The altitude line bisects the base of the triangle to form 2 right angled triangles with hypotenuse = 6 and the base = 3.
So, by the Pythagoras theorem the altitude is calculated as follows:
6^2 = 3^2 + x^2
x^2 = 36 - 9 = 27
x = √27
= 5.20 to the nearest hundredth.
Answer:
152 photons
Step-by-step explanation:
Data provided in the question:
wavelength of the green light, λ = 550 nm = 550 × 10⁻⁹ m
Total energy = 5.50 × 10⁻¹⁷ J
Now,
Energy =
here,
n = number of photons
h = Plank's constant = 6.63 × 10⁻³⁴ J.s
c = speed of light = 3 × 10⁸ m/s
Therefore,
5.50 × 10⁻¹⁷ J =
or
( 5.50 × 10⁻¹⁷)( 550 × 10⁻⁹) = n(6.63 × 10⁻³⁴)(3 × 10⁸)
or
3025 × 10⁻²⁶ = n(19.89 × 10⁻²⁶ )
or
n = 152.086 ≈ 152 photons
Answer:
169
Step-by-step explanation:
V=π (x) r (x) 2 (x)
h= π·32·6
≈169.646
We are asked to find the positive angle that is co-terminal to 132°.
We know that co-terminal angles are angles who share the same initial side and terminal sides.
To find the positive angle that is co-terminal to 132°, we will add 360 degrees to 132°.
Therefore, the positive angle that is co-terminal to 132 degrees is 492 degree and option A is the correct choice.
