A man stands on his balcony, 130 feet above the ground. He looks at the ground, with his sight line forming an angle of 70° with
jenyasd209 [6]

Answer:

d =  380 feet

Explanation:

Height of man = perpendicular= 130 feet

Angle of depression = ∅ = 70 °

distance to bus stop from man = hypotenuse = d = 130 sec∅

As sec ∅ = 1 / cos∅

so d = 130 sec∅    or d = 130 / cos∅

d = 130 / cos(70°)

d =  380 feet

A photon has an energy of 5.53 à 10¯17 j. what is its frequency in s¯1?
Butoxors [25]
<span>energy is directly proportional fo frequency 
as in blue photons are more energetic than red photons 
so 
E = h * f 
look up h (Planck's constant)

Without the wheels, a bicycle frame has a mass of 6.71 kg. Each of the wheels can be roughly modeled as a uniform solid disk wit
dalvyx [7]

Answer:43.311 J

Explanation:

Given

mass of frame\left ( m_f\right )=6.71 kg

mass of  wheel \left ( m_w\right )=0.820 kg

radius of wheel\left ( r\right )=0.343 m

v=3.22 m/s

Moment of inertia of each wheel\left ( I\right )=\frac{1}{2}mr^2[/tex]

I=0.0482 kg-m^2

kinetic Energy of whole cycle=Kinetic energy of wheels and frame+rotational energy of Wheels

K.E.=\frac{1}{2}\left ( m_f+m_w\right )v^2+2\times \frac{1}{2}I\omega ^2

K.E.=\frac{1}{2}\left ( 6.71+0.820\right )3.22^2+2\times \frac{1}{2}0.0482\times \left ( \frac{3.22}{0.343}\right )^2

K.E.=39.037+4.274=43.311J
