How dose a scientific theory differ from a hypothesis?

Physics
1 answer:
damaskus [11]3 years ago

Answer:This is the Difference Between a Hypothesis and a Theory. ... In scientific reasoning, a hypothesis is an assumption made before any research has been completed for the sake of testing. A theory on the other hand is a principle set to explain phenomena already supported by data.

In a digital multimeter, what changes inside the meter when you push the button to change from 200v range to the 20v range? by w
charle [14.2K]
So we want to know what changes inside the multimeter when we change the voltage range from 200 V to  20 V, by what factor and does it increase or decrease. What we want when trying to measure the voltage with a multimeter is that a minimal current passes trough the mulitmeter so when we change the voltage range, we decrease the resistance by a factor of 10 because the voltage is decreased by a factor of 10.

You are watching an archery tournament when you start wondering how fast an arrow is shot from the bow. Remembering your physics
lianna [129]
<h2>Answer:</h2>

<em><u>Velocity of throwing arrow = 43.13 m/s.</u></em>

<h2>Explanation:</h2>

In the question,

Let us say the height from which the arrow was shot = h

Distance traveled by the arrow in horizontal = 61 m

Angle made by the arrow with the ground = 2°

So,

From the <u>equations of the motion</u>,

61 =u.t\\t=\frac{61}{u}

Now,

Also,

Finally, the angle made is 2 degrees with the horizontal.

So,

Final horizontal velocity = v.cos20°

Final vertical velocity = v.sin20°

Now,

u = v.cos20° (No acceleration in horizontal)

Also,

v=u+at\\vsin20=0+9.8(t)\\t=\frac{v.sin20}{9.8}

So,

We can say that,

\frac{v.sin20}{9.8}=\frac{61}{v.cos20}\\v^{2}.sin20.cos20=597.8\\v^{2}=1860.56\\v=43.13\,m/s

<em><u>Therefore, the velocity with which the arrow was shot by the archer is 43.13 m/s.</u></em>

Which sentence provides evidence that heat travels from Earth’s mantle up to its crust?
olasank [31]

B. Earth’s outer surface is cooler than its interior layers.

Explanation:

  • The option given above is showing us that the temperature in the interior of the earth is higher than the temperature in the outer layer.
  • There is travel of heat from the inner core of the earth to the earth's crust. Due to the loss of heat when it reaches the outer layer, there arises a temperature difference.
  • The heat loss is due to the absorption of heat during its transfer. Hence, option B is the answer.

What is the biggest similarity between sports in the United States and sports in other cultures?
leva [86]

Answer:

The first difference is fairly straightforward: other countries prefer other sports. While some aspects of American sports culture are universal there are other things that are sports-specific, such as the 7th-inning stretch at a baseball game or counting the steps of a basketball player after he fouls out.
