-2/5 = 11k - k
-2/5 = 10k
-2/5/10 = k
-2/5 * 10 = k
-2/50 = k
k = -1/25.

-1/25 - 2/5 = 11k is true.

Explaining How Light Bends in<br> Explain how light bends during diffraction
evablogger [386]

Answer:

Explanation: light waves against itself, which leads to internal interference of different wave component Which is also referred to as diffraction.

Diffraction causes beam of light to slowly spread out as it travels, so that some of the light will bend away from a straight line motion of the main part of the wave

A busy waitress slides a plate of apple pie along a counter to a hungry customer sitting near the
Ostrovityanka [42]

Answer:

a. 0.5307 sec

b. 0.4458 m

c. =v_x=0.84\ m/s\ ,\ v_y=5.2\ m/s

Explanation:

Horizontal Motion

It describes the dynamics of an object thrown horizontally in free air. The initial horizontal velocity is maintained all the time since no horizontal forces are acting. The initial vertical velocity is zero at launch time, but it grows downwards powered by the acceleration of gravity.  

The object hits the ground at a distance x from the point of launching, after having traveled a vertical distance y_o, taking a time t to complete the travel. The formulas who relate the different magnitudes are

v_x=v_o

The horizontal velocity v_x is the same regardless of the elapsed  time

v_y=gt

x=v_ot

\displaystyle y=y_o-\frac{gt^2}{2}

The plate of apple pie left the counter at a speed  

v_o=0.84\ m/s

The counter is y_o=1.38\ m high.

a.

Knowing that

y_o=1.38\ m

We use this formula to compute t

\displaystyle y=y_o-\frac{gt^2}{2}

At the moment when the plate hits the floor y=0

\displaystyle 0=y_o-\frac{gt^2}{2}

\displaystyle y_o=\frac{gt^2}{2}

Solving for t

\displaystyle t=\sqrt{\frac{2y_o}{g}}

\displaystyle t=\sqrt{\frac{2(1.38)}{9.8}}

t=0.5307\ sec

b.

x=(0.84)(0.5307)

x=0.4458\ m

c.

v_x=0.84\ m/s

v_y=(9.8)(0.5307)

v_y=5.2\ m/s

A boat heads directly across a river. Its speed relative to the water is 2.6 m/s. It takes it 355 seconds to cross, but it ends
Zigmanuir [339]

Answer:

Vr = 3.24m/s

The boat is going 3.24m/s relative to the bank of the river.

Explanation:

The relative speed of the boat to the bank Vr is the resultant of speed of boat relative to the water Vb and the speed of boat as a result of the water current or wind Vw

Vr = √(Vb^2 + Vw^2) .....1

Given;

Vb = 2.6m/s

Vw = distance downstream/time = 690m/355s

Vw = 1.94m/s

From equation 1 above; substituting the values

Vr = √(2.6^2 + 1.94^2)

Vr = 3.24m/s

The boat is going 3.24m/s relative to the bank of the river.

Quentin is playing baseball and is batting. He swings and hits the ball sending it flying to the outfield. Which is greater- the
Bess [88]

Answer:

The force of the ball on the bat is same as the force of the bat on the ball.  

Explanation:

A bat hits the ball and the ball moves to the out filed.

According to the Newton's third law, for every action there is an equal and opposite reaction.

The action and the reaction forces acts on the two different bodies but the magnitude of the force is same.  

As the ball is hitted by the bat, the bat exerts the force on the ball and the same force is exerted on the bat by the ball according to the Newton's third law.

So, the force of the ball on the bat is same as the force of the bat on the ball but the direction of force is opposite.
