Convert 1.4×10^9km^3 into cubic meters
2 answers:
Explanation: Hi! here we have 1.4×10^9km^3 and want to write this quantity in meters.
First, a kilometer is one thousand meters, so 1km = 1000m, so =
. = 10^9 m^3
so changin this in our quantity we get 1.4×10^9km^3 = 1.4×10^9*10^9 m^3=1.4×10^18m^3
and there you hace the original quantity written in meters.

Answer:
The horizontal component of the velocity is 21.9 m/s.
Explanation:
Please see the attached figure for a better understanding of the problem.
Notice that the vector v and its x and y-components (vx and vy) form a right triangle. Then, we can use trigonometry to find the magnitude of vx, the horizontal component of the velocity.
To find vx, let´s use the following trigonometric rule of right triangles:
cos α = adjacent / hypotenuse
cos 5.7° = vx / 22 m/s
22 m/s · cos 5.7° = vx
vx = 21.9 m/s
The horizontal component of the velocity is 21.9 m/s.
