Light travelling in a vacuum is the fastest thing in the universe. The speed would be 2.99x10^8 m/s. The answer to this question is 'vacuum', where light can travel the fastest. I hope this helps you. You're welcome!
Answer:
(a) dime
Explanation:
Convert all to metric unit:
0.5 cm = 0.005 m
1.8 cm = 0.018 m
71 cm = 0.71 m
In order to find out we would need to calculate the ratio R between the object diameter d and their distance s to our eyes:
Since the ratio of the dime is larger than the ratio of the moon, and the ratio of the pea is smaller than the ratio of the moon, only the (a) dime can cover your view of the moon.
Answer:
Explanation:
If I assume that the wind did not cause the plane to chage its velocity.
The plane will have a velocity of vp = (0*i + 100*j) km/h relative to ground
The cart has a velocity of vc = (0*i - 20*j) km/h relative to the plane
vc' = vc + vp
vc' = (0*i + 100*j) + (0*i - 20*j) = (0*i + 80*j) km/h relative to the ground.
If I assume that the wind move the plane:
The plane will have a velocity of vp = (-40*i + 100*j) km/h relative to ground
The cart has a velocity of vc = (0*i - 20*j) km/h relative to the plane
vc' = vc + vp
vc' = (-40*i + 100*j) + (0*i - 20*j) = (-40*i + 80*j) km/h relative to the ground.
In reality the wind would move the plane a little, not to the full speed of the wind, somewhere between these two values, but without more data it cannot be calculated.
Answer:
The answer is B.
Explanation:
Hurricanes are known to cause strong storms and heavy flooding.
The length of the rope Leo needs to purchase will be 45.3125 ft.
<h3 /><h3>How can you find out surface area ?</h3>
Surface area is calculated for common forms such as circles, triangles, parallelograms, rectangles, trapezoids, and so on.
When a form that isn't a standard figure appears, we slice it into standard shapes to get its area. The area of those component forms is then calculated and added together.
The surface area of the prism is,35 ft²
The length of the rope Leo needs to purchase;
L=5 ×9.0652
L=45.3125 ft
Hence,the length of the rope Leo needs to purchase will be 45.3125 ft.
