Answer:

False

Explanation:

In science, Hypothesis  is not an established theory it is just a supposition. It is not necessary that a hypothesis must be true because it is an assumption or an idea which is always tested with an experiment. After carrying out an experiment it can be determined whether the hypothesis is true or false.

Example:

De-Broglie Hypothesis:

De-Broglie gave an hypothesis that light is not a wave nor it posses particle nature but it posses duel nature. According to De-Broglie hypothesis with each moving particle a wave is associated.

But after experiment it is found that with each moving particle a single wave is not associated but a group of wave is associated.

In this way we can say that hypothesis is not always true.

That's false.  A hypothesis may be accurate or full of beans.  That's why you do experiments, to test it.

Mike's car, which weighs 1,000 kg, is out of gas. Mike is trying to push the car to a gas station, and he makes the car go 0.05
Maru [420]

Answer:

The answer to your question is: F = 50 N

Explanation:

Data

mass = 1000 kg

acceleration = 0.05m/s2

F = ?

Formula

F = m x a

Substitution

F = 1000 kg x 0.05 m/s2 = 50 kgm/s2 = 50 N

Mike is applying a force of 50 N to the car.

At a country music festival, a band is playing at the end of a crowded
Dominik [7]

Answer:

2270 full wavelengths.

Explanation:

The wavelength \lambda of the sound wave (assuming sound speed of  v= 343m/s) is

\lambda = \dfrac{v}{f} = \dfrac{343m/s}{400hz}

\lambda = 0.8575m.

Now, assuming the distance to the last row is 1947m, the number n of wavelengths that fit into this distance are

n = \dfrac{1947m}{0.8575m}

n= 2270.55

which is 2270 full wavelengths.

Hence, there are 2270 full wavelengths between the stage and the last row of the crowd.

Light years are smaller in distance than astronomical units
elena55 [62]
That's false. It's the other way around. One light year is a distance that's a little farther than 63,000 astronomical units.
