Jasmine and her partner want to test to see if there is a relationship between how much of her solar panel is exposed to sunligh

t and how fast her solar car will move. She uses a piece of paper to cover the solar panel different amounts of her solar panel. The chart below shows the data she collected.
Which of the following is the best reason for Jasmine and her partner to take three (3) different trials for this experiment?
They had to fill out all of the lines on the chart.
They wanted at least 15 points to put on her graph.
Any one trial might have been done incorrectly.
The car didn’t work at first.

Como surgiu a capoeira?
xz_007 [3.2K]
La capoeira se desarrolló en Brasil, derivada de las tradiciones traídas a través del Océano Atlántico por africanos esclavizados y alimentadas por el ardiente deseo de libertad. Pronto se practicó ampliamente en las plantaciones como un medio para romper los lazos de la esclavitud, tanto física como mentalmente.

for the primitive yo-yo in fig, to find the downward acceleration of the cylinder and the tension in the string. you can take th
mixas84 [53]

The downward acceleration of the solid cylinder at the given tension in the string is determined as 2Tr/MR.

<h3>Downward acceleration of the cylinder</h3>

The downward acceleration of the solid cylinder is determined from the principle of conservation of angular momentum as shown below;

Iα = Tr

where;

  • I is moment of inertia of the solid cylinder
  • α is angular acceleration of the cylinder
  • T is tension in the string
  • r is length of the string

α = Tr/I

\frac{a}{R} = \frac{Tr}{I} \\\\\frac{a}{R} = \frac{Tr}{\frac{1}{2} MR^2}\\\\\frac{a}{R} =\frac{2Tr}{MR^2} \\\\a = \frac{2Tr}{MR}

where;

  • a is the downward acceleration of the solid cylinder
  • R is radius of the cylinder

Thus, the downward acceleration of the solid cylinder at the given tension in the string is determined as 2Tr/MR.

A raccoon falls out of a tree from a height of 1.2. Which equation can you use to calculate the time it takes for the raccoon to
Inga [223]

Answer:

t=\sqrt{\frac{2S}{g}}=\sqrt{\frac{2 \cdot 1.2 m}{9.81 m/s^2}}=0.50 s

Explanation:

The equation that we can use to calculate the time it takes for the raccoon to fall to the ground is:

t=\frac{2S}{g}

where S=1.2 m is the height of the tree and g=9.81 m/s^2 is the acceleration due to gravity. This equation is derived from the equation of the distance in a uniformly accelerated motion, which is given by

S=S_0 + v_0 t + \frac{1}{2}at^2

where S0 is the initial position, v0 is the initial velocity and t the time. In this problem, we can put S0=0 (we can take the initial position as the initial position of the raccoon) and v0=0 (the raccoon starts from rest), so the equation becomes

S=\frac{1}{2}at^2

and since the motion is a free fall, the acceleration is equal to the acceleration of gravity, so a=g:

S=\frac{1}{2}gt^2

And by re-arranging it, we find

t=\sqrt{\frac{2S}{g}}

By substituting numbers, we find

t=\sqrt{\frac{2S}{g}}=\sqrt{\frac{2 \cdot 1.2 m}{9.81 m/s^2}}=0.50 s
