(i) The slope of [tex]{V_{0}}[/tex] versus [tex]{\nu}[/tex] graph= (h/e) i.e it is a constant quantity and does not depend on the nature of the metal surface

______ interference occurs when two waves are out of phase.

Answers

Answer:

What interference occurs when two waves are out of phase?

Image result for ______ interference occurs when two waves are out of phase.

Destructive interference

Destructive interference occurs when the maxima of two waves are 180 degrees out of phase: a positive displacement of one wave is canceled exactly by a negative displacement of the other wave. The amplitude of the resulting wave is zero.

A duck has a mass of 2.70 kg. As the duck paddles, a force of 0.110 N acts on it in a direction due east. In addition, the current of the water exerts a force of 0.220 N in a direction of 47.0° south of east. When these forces begin to act, the velocity of the duck is 0.120 m/s in a direction due east. Find (a) the magnitude and (b) the direction (relative to due east) of the displacement that the duck undergoes in 2.70 s while the forces are acting. (Note that the angle will be negative in the south of east direction.)

Answers

a) The magnitude will be 0.838m

b) The displacement will be -17.35°

What is displacement?

The path covered by an object from its initial point to final point.

Forces acting on the duck

x-axis:    0.13 + 0.16*cos(-56°) = 2.7 * ax  

ax = 0.0813 m/s^2

y-axis:    0.13*sin(-56°) = 2.7 * ay  

ay = -0.0491 m/s^2

The displacement on the x-axis

X = Vox * t + ax/2 * t²

X = 0.12* 3.2 + 0.0813/2*3.2²

X = 0.8

The displacement on the y-axis:

Y = Voy * t + ay/2 * t²

X = 0 - 0.0491/2*3.2²

Y=-0.25m

So, the magnitude and angle of this displacement [0.8,-0.25] is:

0.838m  at an angle of -17.35°

Tom is sitting facing forward in the train as it is getting ready to leave the station. He puts a smooth ball on the train floor. The train jolts into motion, accelerating rapidly up to speed. According to Newton's first law of motion, what happens to the ball? (1 point)

A) Nothing changes.
B) The ball rolls forward slowly.
C) The ball rolls forward rapidly.
D) The ball rolls backward.

Answers

According to Newton's first law of motion, what happens to the ball is  the ball rolls backward.

What is the first law?

This means that an object at rest or in motion will remain uniformly rectilinear and tend to be in that state if the net force on it is zero.

In this case, we have to think that the ball is at rest and the train is moving with a velocity that way, the reaction of the ball will be to go in the opposite direction to the motion.

How does a real image differ from a virtual image?

Answers:
A real image is always upright and never inverted.


A real image is formed by extending the rays back to where they appear to come from.


A virtual image is always smaller than the object.


Light rays actually pass through a real image.

Answers

Answer:

Real images are obtained using a converging lens or a concave mirror. The size of the real image depends upon the placement of the object. A virtual image is an upright image that is achieved where the rays seem to diverge. A virtual image is produced with the help of a diverging lens or a convex mirror.

Answer:

Light rays actually pass through a real image.

Explanation:

Option C is somehow correct but the hurdle is that it's only for convex mirror

The concave mirror always produce a virtual image larger than object

On your vacation, you take a plane from Atlanta to San Francisco (3400 km). The flight takes 4.0 hours. The first ten minutes and the last ten minutes are spent speeding up and slowing down respectively. Therefore, you reach your top speed 10 minutes into the flight. What was your average speed on this flight?

Answers

Answer:  S =  850 km/h = 235.11 m/s

Explanation:

average speed  = total distance : total time elapsed

           distance = 3400 km

           total time = 4 hours

average speed = D : T =  3400 km : 4 h = 850 km/h

[ 850 km /h = 850 000 m : 3600 s = 236.11 m/s ]

06.** A block takes twice as long to slide down an inclined plane that makes an angle of 35 with the horizontal as it does to fall freely through the same vertical distance h. What is the coefficient of kinetic friction? [μ = 0.16] ​

Answers

The coefficient of kinetic friction between the block and the incline is 0.168.

Coefficient of kinetic friction

The coefficient of kinetic friction is determined from the principle of conservation of energy as follows;

distance traveled on the incline = L

L = h/sin35

L = 1.743 h

Since it takes twice the time travel down,

velocity to slide = 1.743 h/2t = 0.871 v

v is the velocity to drop from the vertical height

K.E of the block when it slides = ¹/₂mv₁²  = ¹/₂m(0.871v)² = 0.871²(K.E to fall) = 0.758K.E to fall straight down

Energy lost to friction

1 - 0.758 = 0.24

Conservation of energy

μmgcos(35) = 0.24(mgsin(35)

μcos(35) = 0.24(sin(35)

μ = 0.168

An elevator is moving upward with a speed of 9.2 m/s. 3.8 seconds later, the elevator is still moving upward, but its speed has increased to 15.8 m/s. What is the average acceleration, in m/s2, of the elevator during the 3.8-s interval? Please round your answer to one decimal place.

Answers

From the calculations, the acceleration of the elevator is obtained as 1.5m/s^2

What is acceleration?

The term acceleration has to do with the rate of change of velocity with time.

Given that;
