How do determine which is Y2, Y1, X2, and X1 on a graph. <br><br> And how do find rise over run.
fredd [130]
One point will be X1,Y1 and the other will be X2,Y2. It does not matter which is which except that X1 and Y1 have to be the same point and X2 and Y2 have to be the same point. For example, let's say you were given (2,3) and (6,8). No matter which point is X1,Y1 and the other is X2,Y2, the slope will still be 5/4. 

The rise is the change in y from one point to the other. The run would be the change in x from one point to the other.

Olympic skier Tina Maze skis down a steep slope that descends at an angle of 30∘ below the horizontal. The coefficient of slidin
LekaFEV [45]

net force on Maze during his sliding downwards motion

F = mgsin30 - \mu mg cos30

now we will have

F = mg(sin30 - 0.10cos30)

now to find the acceleration we will have

a = \frac{F}{m}

a = g(sin30 - 0.10cos30)

a = 9.81(0.5 - 0.10(0.866))

a = 4.1 m/s^2

now to find the speed after 4 s is given by kinematics

v_f - v_i = at

here we know that

v_i = 0

v_f - 0 = 4.1(4)

v_f = 16.22 m/s

so Maze speed after 4 s will be 16.22 m/s

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. The athlete is able to rotate the ball at the
Alexandra [31]

Answer:

a) \omega _1=7.56rev/s=>47.5rads/s

b) a=30.7

c) a=35.91

Explanation:

From the question we are told that:

Initial angular velocity \omega _1=7.56rev/s=>47.5rads/s

Initial Length L_1=0.600m

Final angular velocity \omega _2=6.22rev/s=39rad/s

Final Length L_2=0.900m

a)

Generally the rotation with the greater speed is

\omega _1=7.56rev/s=>47.5rads/s

b)

Generally the equation for centripetal acceleration at 8.16 is mathematically given by

a=\omega_1^2*L_1

a=8.16 rev/s*0.6

a=30.7

c)

At 6.35 rev/s

a=6.35 rev/s*0.9

a=35.91

Light is described as having a dual wave-particle nature. Which piece of evidence provides support for the model of light as a w
S_A_V [24]

Answer:

The evidence that supports the wave particle nature of light as a wave is:

"Light reflects when it hits a surface."

Explanation:

Light exhibit wave-particle duality. This means, in some cases the properties of light are just like a wave and in other cases it behaves as particles.

The properties like reflection or refraction from a surface are attributed as properties of waves. The phenomena of interference and diffraction also fall in this category.

Therefore, from the given options, the only option that supports the evidence of light as a wave is "Light reflects when it hits a surface", as reflection is entirely the property of a wave.
