QUICKLY I AM IN THE LESSON NOWWW
vladimir2022 [97]

Answer:

I don't really know much about the whole stars thing, but I've written a lot of paragraphs in science

Explanation:

Remember:

  • A paragraph should be in CER formation: Claim (hypothesis/discovery), Evidence, and Reasoning
  • Your reasoning should never start with I believe or I think, your reasoning and evidence are 100% fact based
  • The actual hypothesis should only be 1-2 sentences and be straight to the point

Include:

  • for your hypothesis, keywords relating to your subject, I'm assuming  for your topic you should include things like marking, telescope, stars, etc.
  • why you believe your hypothesis is true
  • so use prior knowledge to justify your hypothesis

The best leaper in the animal kingdom is the puma, which can jump to a height of 3.7m when leaving the ground at an angle of 45
zheka24 [161]

Answer:

v = 12 m/s

Long, boring, and convoluted explanation:

First, let's lay out our information.

- <em>max height = 3.7 m</em>

- <em>0 = 45°</em>

<em>- gravitational acceleration constant = 9.8 </em>\frac{m}{s^2}<em />

<em />

Since the puma leaves the ground at a <em> 45 °</em> angle, its motion will follow a curved path as seen in many projectile motion problems, where the object is being influenced solely by the force of gravity. And because the puma leaves the ground at an angle, its initial velocity is broken down into its horizontal and vertical components. We were also told, though indirectly, that the max height is  <em>3.7m</em>  because the puma can reach up to that height. Gravity is always given to be <em>9.8 </em>\frac{m}{s^2}<em />

<em />

Because we are dealing with maximum height and gravity, we have to use the vertical component of the velocity,  <em>vsin ( θ )</em> , and not the horizontal component, <em>vcos ( θ )</em> .

Given its max height, the acceleration due to gravity, and the angle, we can now solve for the speed at which the puma leaves the ground using the following equation: <em>vsin ( θ )  = </em> \sqrt{2hg}

Where <em> vsin ( θ )</em>  is the vertical component of the initial velocity and <em>h</em>  and <em>g</em> are max height and gravitational acceleration constant respectively.

Plugin, rearrange and solve

v sin ( θ )  =  \sqrt{2hg}

v sin ( 45 ∘ )  =   √ 2  ×  3.7  ×  9.8

v ( 0.71 )  =  \sqrt{72.52}

v ( 0.71 )  =  8.52

v  =  8.52 /0.71

v =  12 m s

How does Lightning occur<br><br>​
OlgaM077 [116]
When a storm is formed, the storm clouds contain negative charges and the ground is filled with positive charges. Similar to the way magnets work the two are attracted. The the collision of the two charges produce an electrical discharge.

I hope this helped!

when the driver touches A Car steering wheel on a hot day heat is transferred to the driver's Hands by
Masteriza [31]
Heat is transferred to the driver's hands by conduction. The direct contact between the steering wheel and the driver's hands allows heat from molecules on the surface of the steering wheel to transfer to the molecules on the surface of the driver's hands. This is in contrast to convection (which requires a fluid in between the two surfaces that transfers heat).
