Answer:
SI system of mesurment is used by most countries around the world.
Answer:
The horizontal component is 96.42 N
The vertical component is 114.91 N
Explanation:
A force 150 newtons is inclined at 50 degrees to the horizontal direction
We need to find its component in the horizontal and vertical directions
is the horizontal component
is the vertical component
Look to the attached figure:
The horizontal component is the product of F and cosine
the angle between F and the horizontal
The vertical component is the product of F and sine
the angle between F and the horizontal
→ = F cos(50)
→ = 150 cos(50)
→ = 96.42 N
→ = F sin(50)
→ = 150 sin(50)
→ = 114.91 N
<em>The horizontal component is 96.42 N</em>
<em>The vertical component is 114.91 N</em>
Given: Plank's constant h = 6.626 x 10⁻³⁴ J.s
Speed of light c = 2.998 x 10⁸ m/s
Wavelength λ = 500 nm convert to meter = 5 x 10⁻⁷ m
Required: Energy E =?
Formula: E = hc/λ
E = (6.626 X 10⁻³⁴ J.s)(2.998 X 10⁸ m/s)/5 x 10⁻⁷ m
E = 3.97 X 10⁻¹⁹ J or in termS of electron volt
E = 2.48 eV
Answer:
what language is that
