The correct option is B.
There are many hazards that may occur as a result of globalization. One of this is the violation of human right by companies. This can occur in several ways, for instance, there are some companies from developed countries which introduce hazardous technological devices to less developing countries.
Answer:
tA=tB
tB=(sA-dA)/vA watch it below
Explanation:
the spatio for A is sA=vA*tA+dA
the spatio for B is sB=vB*tB
the meeting point will happen at: tA=tB
so, sA=vA*tB+dA
tB=sB/vB
yields:
sA=vA*(sB/vB)+dA
sA-dA=vA*(sB/vB)
sB=(sA-dA)*vB/vA
then
tB=((sA-dA)*vB/vA)/vB
tB=(sA-dA)/vA
Answer:
We can use optical fibers.
Explanation:
The optical fibers are the optical devices which is based on the total internal reflection.
The optical fiber has two layers, one is called core and the other is called cladding.
The refractive index of core is more than the cladding.
As a ray of light falls on the core at more than the critical angle for that pair of media(core and cladding), it suffers the total internal reflection at the interface.
Answer:
They can give us information and energy.
Explanation:
Fossils can be burned to give us energy and fuel. They can also give us information about the earths history.
Answer:
60 m
Explanation:
After 3 seconds of travel at 20 m/s, the projectile is 3·20 = 60 meters horizontally from the cannon.
__
The vertical height after 3 seconds is 0.9 m, so the straight-line distance from cannon to target is √(60^2 +0.9^2) ≈ 60.007 meters.
