Answer:

False.

Explanation:

The hypothesis can be defined as the explanations or suppositions that are acceptable  in order to prove some natural phenomena by the help of experimental procedure.

And you can use your data which is gather from the experiment and formulate a new hypothesis.

A hypothesis is the data which is not depend on the experimental data, it can be say that it is just a not dependent hypothesis.

This is false. Your hypothesis, or prediction, is just that: a prediction. Saying its a failure will result in bias.

Sound with frequency 1220Hz leaves a room through a doorway with a width of 1.13m . At what minimum angle relative to the center
mel-nik [20]

Answer:

θ = 14.45º  = 0.252 rad

Explanation:

The expression that describes the phenomenon of diffraction is

    a sin θ = m λ

Where a is the width of the exit opening in this case the width of the door, Lam is the wavelength, m the diffraction order for destructive interference,

Let's use the relationship between the speed of the wave is the producer of its frequency by the wavelength

    v = λ f

   λ = v / f

    λ = 344/1220

   λ = 0.282 m

   sin θ = m  λ / a

For the first destructive interference m = 1

   sin θ = 1 0.282 /1.13

  sin θ = 0.24956

  θ = sin-1 (0.24956)

  θ = 14.45º

We pass radians

   θ = 14.45 (pi rad / 180º) = 0.252 rad

What happened from the mid 1700s to the mid 1800s that contributed to the change in the global human population?
marin [14]

Industrial revolution is the reason of human population increase in 1700's and 1800's.

<h3><u>Explanation:</u></h3>

Industrial revolution is the event that took in the 18th and early 19th century in Europe and then to other parts of the world. In this revolution, there was huge implementation of machines and artificial objects in the daily lives which hugely contributed to the development of quality of product, greatly decreased the production time and costing, etc.

This led to increase in luxury in the lives of people and there was widespread change in the mode of living of the people all over the world.

He throws a second ball (B2) upward with the same initial velocity at the instant that the first ball is at the ceiling. c. How
Gwar [14]

Answer:

hello your question has some missing parts

A juggler performs in a room whose ceiling is 3 m above the level of his hands. He throws a ball vertically upward so that it just reaches the ceiling.

answer : c) 0.39 sec

               d)  2.25 m

               e) 1.92 m/sec

Explanation:

The initial velocity of the first ball = 7.67 m/sec ( calculated )

Time required for first ball to reach ceiling = 0.78 secs ( calculated )

Determine how long after the second ball is thrown do the two balls pass each other

Distance travelled by first ball downwards when it meets second ball can be expressed as : d = 1/2 gt^2 =  9.8t^2 / 2

hence d = 4.9t^2  ----- ( 1 )

Initial speed of second ball = first ball initial speed = 7.67 m/sec

3 - d = 7.67t - 4.9t  ---- ( 2 )

equating equation 1 and 2

3 = 7.67t   therefore t = 0.39 sec

Determine how far the balls are above the Juggler's hands ( when the balls pass each other )

form equation 1 ;

d = 4.9 t^2 = 4.9 *(0.39)^2 = 0.75 m

therefore the height the balls are above the Juggler's hands is

3 - d = 3 - 0.75 = 2.25 m

determine their velocities when the pass each other

velocity = displacement / time

velocity = d / t = 0.75 / 0.39 sec  = 1.92 m/sec
