m<CAE = 90: definition of perpendicular
p.s. ty for this!
The energy of a photon is given by
E = h × v
where:
E is the energy in joules/photon
'h' is the constant 6.63 × 10⁻³⁴
'v' is the frequency 7.55 × 10¹⁴
Substitute 'h' and 'v' into the formula we have
E = (6.63×10⁻³⁴) × (7.55×10¹⁴)
E = (6.63×7.55) × (10⁻³⁴ × 10¹⁴)
E = 50.0565 × 10⁽⁻³⁴⁺¹⁴⁾
E = 50 × 10⁻²⁰ joules/photon
Ok so I’m assuming the question is how the tall is we need to find the Angle of the sun so
Student : 175
Shadow: 2.3
Hypotenuse: 175.0151136
Using -cos(175/175.0151136) we find the
Suns angle: .753 Above him/her
Our tree’s shadow:8.2
Using the suns angle we use cos(x
Answer:
[7 6]
[7 4]
Step-by-step explanation:
Answer:
240 minutes (4 hours)
Step-by-step explanation:
the descend 3000 ft every 20 minutes
36000 ÷ 3000 = 12
20*12 = 240 minutes
