Answer:
Explanation:
Given that
Diameter of laser beam d= 2.4 mm
Radius of laser beam r= 1.2 mm
Power P =1.7 W
We know that intensity(I) of laser beam given as follows
Now by putting the values
So
So the intensity at 1.76 m away from laser
25 km/h means that 15 kilometers will be 15/25ths of an hour. Therefore, 3/5 of an hour is 36 minutes, so it would take 36 minutes to fly that distance.
Answer:
the answer is C
Explanation:
i took the test just now so i am glad i can help someone in the future❣❣❣❣
<u><em>Also here is the explanation</em></u>
Note that the magnitude of acceleration (a) is given by a =
v2
R
, where v is the speed and R is the radius. Because acceleration is the same for both bikers, the ratio 
v2
R
, also has to be the same for both. Given that Kevin’s speed is higher, the radius of his path must also be higher to maintain the same ratio. Therefore, Kevin’s circular path has a bigger radius than Linda’s path.
Explanation:
Such spheres are intimately connected. Many animals (biosphere), for example, migrate through to the sky, while groundwater (hydrosphere) also flows through the ground (lithosphere). The domains are actually so closely related that a shift in one globe always results in a shift in one or both of some other spheres.
Answer:
A hypothesis
