Answer:

What's the question?

Explanation:

Answer:

Because always when we do an experiment, we need something to compare.

For example, if we want to see how much change a given color paint when we add different amounts of white paint to it, we need to have at least one sample of pure color paint, so we can compare it whit the ones with mixed paints.

Well, the case of the polygraph is exactly the same, we need to have a baseline, so we the interviewer can see if for some questions there is a change in the line compared with the baseline.

Answer:

The length is [tex]s = 3.73 \ m[/tex]

Explanation:

From the question we are told that

  The speed is  [tex]v = 3.054 \ m/s[/tex]

  The acceleration [tex]a = -0.7762 m/s^2[/tex]

   The time taken is  [tex]t = 1.51 \ s[/tex]

Generally from kinematics equation the length of the inclined plane is mathematically represented as

         [tex]s =ut + \frac{1}{2} * at^2[/tex]

=>      [tex]s = 3.054 *1.51 + \frac{1}{2} * (-0.7762) *(1.51)^2[/tex]

=>   [tex]s = 3.73 \ m[/tex]

Explanation:

the major fuels for muscle are glucose fatty acids, and ketone bodies. muscle differs from the brain in having a large store of glycogen

Answer:

D. Glycogen

Explanation:

About 3/4 of all the glycogen in the body is stored in muscle.

You had me worried there for a second.  I thought you were going to ask how much the time changes, or how much the speed changes as it hits the ground, and I was gonna skip this question and go to bed.

But the acceleration won't change.  That's always 9.8 m/s².  That's the acceleration of gravity on Earth. It doesn't depend on what you drop, or what its mass is, or how heavy it is, or what color it is, or how high you drop it from. The only way you can change it is to drop the rock through air or water, or on a different planet.

Answer:

no idea man i say the third one

Explanation:

Answer:

a) 19.6 m/s, 19.6 m

b) 58.8 m/s, 176.4 m

Explanation:

Take down to be positive.  Given:

v₀ = 0 m/s

a = 9.8 m/s²

a) Find v and Δy when t = 2.0 s.

v = at + v₀

v = (9.8 m/s²) (2.0 s) + 0 m/s

v = 19.6 m/s

Δy = v₀ t + ½ at²

Δy = (0 m/s) (2.0 s) + ½ (9.8 m/s²) (2.0 s)²

Δy = 19.6 m

b) Find v and Δy when t = 6.0 s.

v = at + v₀

v = (9.8 m/s²) (6.0 s) + 0 m/s

v = 58.8 m/s

Δy = v₀ t + ½ at²

Δy = (0 m/s) (6.0 s) + ½ (9.8 m/s²) (6.0 s)²

Δy = 176.4 m

A sound wave squeezes together and thins out the air molecules around your ear.  The places where these things happen are called the compressions and rarefactions of the sound wave.

The acceleration is the slope of the v/t graph.

-- If the graph is a straight line, then pick any piece of the line, or even the whole graph, and divide (change in 'y') by (change in 'x') for the piece you chose.

-- If the graph is a curve or a squiggle, then you can do the same thing with a piece of it, and you get the average acceleration during that piece.

-- If you need the acceleration at one point on the graph, you have to lay a straight line against that point on the graph, and find the slope of that straight line.

Explanation:

total distance travelled = 400m

total time taken = 4min 45sec = 4*60 + 45 = 285sec

Avg speed = 400/285

                   = 2.162162....m/s

                   = 2.162....m/s

Answer:

An interval is a distinct measure of time or the physical or temporal distance between two things.

Explanation:

The longer the time of the collision, the smaller the force. (B)

That's why, if you fall off the roof, you want to be stopped by a net or a pile of leaves, and not by the ground. You want the stop to last as long as possible. Like everybody says:  It's not the fall that hurts, it's the stop at the end.

The total distance traveled by the dog is 100 m and the displacement of the dog is 58.31 m.

The given parameters;

The displacement of the dog is the change in its initial position and the final position.

The resultant of the dogs position in x-direction: = 40 m - 10 m = 30 m

The resultant of the dogs position in y-direction: 50 m

The magnitude of the displacement;

R² = 30²  + 50²

R² = 3400

R = √3400

R = 58.3 m

The distance covered by the dog is the sum of all the positions of the dog.

Distance = 40 m + 10 m + 50 m

Distance = 100 m.

Thus, the total distance traveled by the dog is 100 m and the displacement of the dog is 58.31 m.

Answer:

The speed at which she threw the marshmallow is approximately 4.76 m/s

Explanation:

The given in formation are;

The range in which the marshmallow was thrown = 2 m (The location of her friend)

The angle at which the marshmallow was thrown = 30 degrees

The horizontal range is given by the following formula;

[tex]R = \dfrac{u^2 \times sin(2\cdot \theta)}{g}[/tex]

Where;

R = The range = 3 m

u = The initial velocity

θ = The angle at which the marshmallow was thrown = 30°

g = The acceleration due to gravity = 9.81 m/s²

By substitution, we have;

[tex]2 = \dfrac{u^2 \times sin(2\times 30)}{9.81} = \dfrac{u^2 \times sin(60)}{9.81}[/tex]

[tex]\therefore u^2 = \dfrac{ 2 \times 9.81}{sin(60)} = \dfrac{u^2 \times sin(60)}{9.81} \approx 22.66[/tex]

u ≈ √(22.66) ≈ 4.76 m/s

u ≈ 4.76 m/s

The speed at which she threw the marshmallow ≈ 4.76 m/s.

Answer:

4.76 m/s

Explanation:

Three students measured the length of a stamp whose accepted length is 2.71 cm, on the basis of the table student 2 is both precise and accurate, therefore the correct answer is option B.

A unit of measurement is a specified magnitude of a quantity that is established and used as a standard for measuring other quantities of the same kind. It is determined by convention or regulation.

The degree to which a measurement is accurate in relation to its true value. The degree to which the same results are produced by repeated measurements under the same circumstances is known as precision.

Thus, according to the chart, student 2 is both exact and accurate, hence the proper response is option B. Three students measured the length of a stamp, and the approved length is 2.71 cm.

brainliest pweaseee

Answer:

Yes (and no)

Explanation:

Hey! This according to my theory is possible, the g-force of an object or "elevator" (in your explanation) is accelerating as it's gravitational pull is getting stronger. So it would but wouldn't be possible in a small elevator, because you-know it's an elevator (and of course you would bump your head, ouch!) ; p !

But if you had free or spare space to use, then you can jump upwards at the last second to cancel out the gravitational pull as if you actually (or originally) jumped from this height. But the gravitational pull may be too strong for those of humans, if the person acquiring and accelerating in G-Force doesn't have good leg muscle then he may be pulled along with the object by the gravitation.

Answer:

Armando's weight ,restored force created by the trampoline

a harmonic movement within the trampoline

Explanation:

In a trampoline we have two forces that actuate Armando's weight and the restored force created by the trampoline that depends on the deformation distance of the elastic canvas.

Amando's weight is vertical and directed towards the center of the Earth and has a constant value, this weight is balanced with the elastic force the springboard exerts on Armando in a vertical direction.

In general, when entering the trampoline, a small jump is made, this creates a speed that deforms the canvas until the speed is reduced to zero, at this point the elastic force is greater than the weight and the boy begins to climb, After the boy leaves the canvas he meets only the force of gravity and his speed decreases to zero and begins his fall.
