Answer:
Explanation:
Given
Initial velocity of ball
height of window
Using Equation of motion
where u=initial velocity
t=time
a=acceleration
As ball is already is at a height of 20 m so
(b)highest point is obtained at v=0
where
v=final velocity
u=initial velocity
a=acceleration
s=displacement
Highest Point will be
(c)Time taken when the ball hit the ground i.e. at Y=0
impact velocity

B
Explanation:
Heat increase molecular motion
Answer:
The speed of the stone when it is 4.66 m higher is 236.057 m/s.
Explanation:
Given the initial velocity and vertical distance, we can use the fourth kinematic equation () to find v final, or the v to the left of the equal sign. We know (initial velocity) is 24.7 m/s, y (change in vertical distance) is 4.66 m, and a is another way to write g (acceleration due to gravity), or 9.8 .
From here you could plug in the values and solve for v final, but to make the solving process simpler, we can simplify the given equation, <em>then </em>plug in the known values.
To isolate v final, we can take the square root of and do the same to the right side of the equation. Therefore, we can find v final with: , where v initial is outside of the square root because it squared...
If we plug in the known values to the simplified equation, we get:
The final answer is 236.057 m/s.
Answer:
Solid: metal alloy
Liquid: beer
Gas: Air
Explanation:
A solution is a type of mixture where the solvent and solute are homogeneously mixed. Homogeneous mixture means that the solute shouldn't be able to be seen with the naked eye, filtered and stable enough.
Metal alloy will be an example of a solution in solid-state. Beer is a solution made of liquid alcohol and liquid water. Air mostly composed of nitrogen, but it has oxygen, carbon dioxide, and many other substances in gaseous form.
