Answer:

Explanation:
Let at any moment of time the friend's car is at some horizontal distance "x" from the position of balloon.
Now if the altitude of the balloon is fixed and it is at height "h"
so here we will have

now we know that
initially the angle of the friend's car is 35 degree
so the horizontal distance will be

similarly if the angle after passing the car position is 36 degree
then we have

now the speed of the balloon is constant
so we have




so the final position of friend when the angle is 36 degree


Answer:
b
Explanation:
I'm not so sure but it makes sense
Answer:
To have the same kinetic energy the speed of the marble must be 9 times the speed of rock.
Explanation:
The general formula of kinetic energy is given as follows:

where,
K.E = Kinetic Energy
m = mass of the object
v = speed of the object
So, for the marble and rock to have same kinetic energy, we can write:

<u>Hence, to have the same kinetic energy the speed of the marble must be 9 times the speed of rock.</u>

There are no following but less red blood cells would make you tired because you can carry as much oxygen and more white blood cells could cause infection if the start attacking you. It could also give you bone marrow cancer if there are too many white blood cells.
