y = 11.3380m
<h3>What is Young's double-slit experiment?</h3>
The double-slit experiment is an experiment, that shows that light has both a wave nature or characteristic and a particle nature or characteristic, and that these natures are inseparable.
So, light is said to have wave–particle duality rather than be only a wave or only a particle. The same is true for electrons and other quantum particles.
According to the question,
The relative to angle θ, its adjacent side has length x and its opposite side is equal to width of the river, y;
tanθ = = y = dtanθ
y =( 112m) tan (37.8° )
y ≈ 11.3380m
The width of river is 11.3380m

Answer:
6. Acceleration = 4.74 m/s^2
7. Centripetal force = 40.5 N
Explanation:
Problem 6.
Recall that the centripetal acceleration is defined as: , where V is the object's tangential velocity, and r the radius of the circular motion. Therefore, in or case, the centripetal acceleration would be:
which we can round to 4.74 m/s^2 (option b in your list)
Problem 7.
Now we need to find not just the centripetal acceleration using the same formula as above, but then the centripetal force.
Now we calculate the centripetal force by multiplying this acceleration times the mass of the object following the definition of force as mass times acceleration:
Centripetal force = 5.0 kg * 8.1 m/s^2 = 40.5 N

Answer:
lunar eclipse
Explanation:
if the earth is between to two (not bringing the moons orbit into account) a lunar eclipse happens
Answer:
Explanation:
In order to answer this question, we simply have to refer to the laws of the equations of gravitational mechanics.
The equation given by Newton tells us that
In the case where we compare a specific place where the Force of Gravity is greater or lesser, we focus on the term assigned to the Planet's Radius.
In the case of , we understand that they are constant.
We can easily notice that the more the Radius (Height seen from a viewer on the ground), the lower the force will be.
In other words, the smaller the radius in which the measurement is made with respect to the center of the earth, the greater the gravitational force.
In that order of ideas the smallest radio has South Pole, which is about 6356 km from the center of the Earth on the Equator line
