At first we have to find the time index, but you have to remember that time does not depend on mug's horizontal velocity. In this case : D=1/2∗g∗t2=1.18 where the in. velocity is 1.2/t.
Of course the mug velocity will be the same as previous one :
v=g*t
Then we have θ=tan−1(vy/vx) so that you can easily find what you need using trigonometry.
Answer:
691.13 nm
Explanation:
d = width of the slit = 0.11 x 10⁻³ m
θ = angle of diffraction pattern = 0.72° degree
λ = wavelength of the light = ?
m = order = 2 (since second minimum)
for the second minimum diffraction pattern we use the equation
d Sinθ = m λ
Inserting the values
(0.11 x 10⁻³) Sin0.72 = (2) λ
λ = 691.13 x 10⁻⁹ m
λ = 691.13 nm
Answer: Hi!
A neuron is a basic working unit of the brain. Neurons are special cells designed to transfer information to other nerve, muscle, or gland cells. They are pretty cool - looking too! (A slightly irregular circular shape with branches reaching out from all sides.) A neuron is a nerve cell. Nerve cells are the way of communication in the nervous system.
Hope this helps!
Answer:
The motorbike is traveling at 40 m/s
Explanation:
100m over 2.5 seconds or 100/2.5 is 40 m/s
Ek= 1/2mv²
200=1/2 m(9 ²)
200=1/2(81)m
200=40.5m
m=200/40.5
m=4.93kg
Answer: 4.9 kg (second option)
