Answer:
B
Explanation:
You would have rain. You would have clouds, precipitation, and strong winds.
Explanation:
The momentum of an object is given in terms of its mass and its velocity. The law of conservation of momentum says that the net momentum of a system remains conserved for an isolated system.
Momentum is given by :
p = m × v
If p is conserved, velocity is inversely proportional to the mass of an object. When mass changes, velocity also changes but inversely.
The answer is a

It is possible to demonstrate that the maximum distance occurs when the angle at which the projectile is fired is

.
In fact, the laws of motions on both x- and y- directions are


From the second equation, we get the time t at which the projectile hits the ground, by requiring

, and we get:

And inserting this value into Sx(t), we find

And this value is maximum when

, so this is the angle at which the projectile reaches its maximum distance.
So now we can take again the law of motion on the x-axis

And by using

, we find the value of the initial velocity v0:
