Answer:
1250![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
Explanation:
Let's look at this in a simple manner, because it is.
The crane weights 250Kg. Okay.
Since it is hung, there is the acceleration of gravity being applied on it (10m/s²)
Since F = m * a
F = 250 * 10
F = 2500
Now we know that the downward Force is 2500N.
To find the force that is being applied on that 30° angle, we can multiply our 2500N by cos30°, which happens to be
.
Therefore, the force pulling the box in the cable's direction is:
![\frac{2500\sqrt{3} }{2} = 1250\sqrt{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2500%5Csqrt%7B3%7D%20%7D%7B2%7D%20%20%3D%201250%5Csqrt%7B3%7D)

To determine the distance of the light that has traveled given the time it takes to travel that distance, we need a relation that would relate time with distance. In any case, it would be the speed of the motion or specifically the speed of light that is travelling which is given as 3x10^8 meters per second. So, we simply multiply the time to the speed. Before doing so, we need to remember that the units should be homogeneous. We do as follows:
distance = 3x10^8 m/s ( 8.3 min ) ( 60 s / 1 min ) = 1.494x10^11 m
Since we are asked for the distance to be in kilometers, we convert
distance = 1.494x10^11 m ( 1 km / 1000 m) = 149400000 km
Answer:
A prism can disperse light into different colors when the light enters the prism at a "fixed" angle - light coming in, perhaps, thru a narrow slit
If light can enter at all angles, then dispersion occurs at all angles and no dispersion can be seen
Density of a material depends upon it's mass & volume.
You can calculate it by: Density = Mass / Volume
Hope this helps!
10 m/s because of gravity
