Answer:
8.2 m/s
Explanation:
radius (r) = 1.3 m
coefficient of friction (u) = 0.19
acceleration due to gravity (g) = 9.8 m/s^{2}
for the passengers to remain stuck on the wall, the normal force must be equal to the centripetal force (while considering the coefficient of friction).
normal force = centripetal force x coefficient of friction
mg = x u
g = x u
v =
v =
v = 8.2 m/s
the minimum speed the passengers can have to stick to the wall = 8.2 m/s
B-thymine nucleotides is the answer i am sure
Answer:
D. Electricity will flow if the electrons are bound loosely to their atoms in the material.
Explanation:
The continuous flow of charges is known as electricity (current). The flow of these charges are due to free or mobile electron within the atoms of the conductors. The materials which will allow current to pass through them, must have free or mobile electrons which are loosely bound to their atoms.
Thus, the correction for this question is "D"
D. Electricity will flow if the electrons are bound loosely to their atoms in the material.
Answer:
= 4,574 10⁻⁵ m
Explanation:
The interference pattern for a two slit system is given by
d sin θ = m λ constructive interference
d sin θ= (m + ½) λ destructive interference
In general and also in this case the screen is far from the slits, so the TT-free can approach the TT
tan θ = y / L
Let's replace
d y / L = m λ constructive interference
d y / L = (m + ½) λ destructive interference
Let's start when there is constructive interference
They give us the frequency of light, let's find the wavelength
c = λ f
λ = c / f
λ = 3 10⁸ / 6.32 10¹⁴
λ = 4.7468 10⁻⁷ m
Let's take the opportunity to reduce the SI system
L = 87 cm = 0.87 m
y = 3.16 cm = 0.0316 m
Now we can find the separation of the slits
d = m λ L / Y
d = 3 4.7468 10⁻⁷ 0.87 / 0.0316
d = 3.92 10⁻⁵ m
We already have all the data, now let's use the destructive interference equation and find
d / L = (m + ½) λ
= (m + ½) λ L / d
= (3 + ½) 4.7468 10⁻⁷ 0.87 / 0.0316
= 4,574 10⁻⁵ m
On sources it says it would just be the super giant star
