Answer:
25 degrees
Explanation:
The angle of incidence equals the angle of reflection
You will use the equation for work which is w= F times distance so you will take 40N times 36N which equals 1440N
Answer:
convert 1 milligram to 1 gram:
Explanation:
1 milligram is 0.001 gram.
so... 2 milligram is 0.002
3 milligrams is 0.003
and so on.
Answer:
C. If the masses of the objects increase, then the force between them also increases.
Explanation:
Answer:
x=2.4t+4.9t^2
Explanation:
This equation is one of the kinematic equations to solve for distance. The original equation is as follows:
X=Xo+Vt+1/2at^2
We know that the ball starts at rest meaning that its initial velocity and position is zero.
X=0+Vt+1/2at^2
Since it is going down the ramp, you can use the acceleration of gravity constant. (9.81 m/s^2) and simplify that with the 1/2.
X=Vt+4.9t^2
Note: Since the positive direction in this problem is down, you are adding the 4.9t^2, but if a question says that the downward direction is negative, you would subtract those values.
Now, substitute in your velocity value.
X=2.4t+4.9t^2
