Answer:
A aceleração do carrinho é de, aproximadamente, 1,46 m/s².
Explanation:
F=ma
F: force
m: mass
a: aceleration
66 = 45a
a=66/45= 22/15 ≅ 1,4666 m/s²
Answer:
The quantity of energy per photon is inversely proportional to the wavelength of the light.
Explanation:
Energy of light is given as
E = hf
where E = energy of the photons,
f = frequency of the light
If the number of photons = n
(E/n) = (h/n) f
Let (E/n) = E'
(h/n) = h'
But the frequency of light is related to wavelength through the relation
v = fλ
where v = speed of light = c
λ = wavelength of light
f = (c/λ)
E' = h' f
Substituting for f
E' = h' (c/λ)
h' and c are both constants, h'×c = K
E' = (K/λ)
So, the quantity of energy per photon is inversely proportional to the wavelength of the light.
Hope this Helps!!!

Force
The magnitude of the average force needed to bring the bicycle and its rider to a stop is
Answer:
products would appear after the raw materials
Explanation:
raw material + raw material = product (anything deriving from combining two materials)
When you are going down you pick up more speed
