Answer: Health is a benefit it can reduce the risk of heart disease as well as help you control your weight. It can also help you improve your mental health and mood. It can also help keep your thinking, learning, and judgement skills sharp as you age.
The acceleration would actually be 1.6 m/s^2. Acceleration= final velocity-initial velocity/time taken. When you do that formula it comes out to equal that.
The missing question is: how many photons are produced per second?
Answer:
Explanation:
The energy of a photon is given by
where
h is the Planck constant
c is the speed of light
is the wavelength of the photon
In this problem, the photons have wavelength
, so each photon has an energy of
The total energy emitted by the bulb in 1 second is
E = 100 J
Therefore, the number of photons emitted per second is
First we need to know the equation:
F= Mass times acceleration
F = 2.0 kg times 5.0 m/s^2
multiply them to get the net force!
F= 10 N
N is newton
Hope this heps
The equation for range is:
R = v₀²sin(2θ)/g
To find the maximum R, differentiate the equation and equate to zero. The solution is as follows:
dR/dθ = (v₀²/g)(sin 2θ)
dR/dθ = (v₀²/g)(cos 2θ)(2) = 0
cos 2θ = 0
2θ = cos⁻¹ 0 = 90
θ = 90/2
<em>θ = 45°</em>
