Answer:
the angle is about 67.79 degrees
Explanation:
We know that at its maximum height, the vertical component of the projectile's launching (initial) velocity (Vyi) is zero, so at that point it total velocity equals the horizontal component of the initial velocity (Vxi = 0.5 m/s)
We also know that the maximum height of the projectile is given by the square of its initial vertical component of the velocity (Vyi) divided by 2g, therefore half of such distance is :

we can use this information to find the y component of the velocity at that height via the formula:

Now we use the information that tells us the speed of the projectile at this height to be 1 m/s. That should be the result of the vector addition of the vertical and horizontal components:

Now we can use the arc-tangent to calculate the launching angle, since we know the two initial component of the velocity vector:

A falling object (directly downward) is slowed down by air resistance. In turn it would take longer to fall.
The 5 sources of chemical weathering is Hydration, oxidation, carbonation, hydrolysis and dissolution are forms of chemical weathering.
Hope this helps.
Answer:
C. equal to
Explanation:
1 Cubic meter (m³) is equal to 1000000 cubic centimeters (cm³). To convert cubic meters to cubic centimeters, multiply the cubic meter value by 1000000.
Answer:
reviewing the statement we can say that it is FALSE
Explanation:
The Doppler effect is the change in the perceived frequency of a sound wave by the RELATIVE MOTION of the source and the observer.
This effect is very useful for finding the speed of an object.
When reviewing the statement we can say that it is FALSE
