Answer:

Therefore the correct answer is B.  Scatterplot

Explanation:

This is an exercise in kinematics, in a measurement of distance against time, the process is described by the expression

          x = vo t + ½ a t2

where vo is the initial velocity. At the acceleration of the body, x the displacement and t the time.

Depending on the type of movement, a can be zero or different from zero.

In general, all these data are graphed in a DISPERSION graph where the distance is on the abscissa axis and the ordinate axis is time.

Therefore the correct answer is B

5-year Treasury bonds yield 4.4%. The inflation premium (IP) is 1.9%, and the maturity risk premium (MRP) on 5-year T-bonds is 0
liberstina [14]

Answer:

The real risk-free rate is 2.1%

Explanation:

Typically, the return on investment is denoted by the below formula:

return on investment=real  risk-free rate+inflation premium+default risk premium+liquidity premium+maturity premium

return on investment is 4.4%

inflation premium is 1.9%

maturity risk premium is 0.4%

liquidity premium is 0%

default risk is also assumed to zero as the treasury bond is backed by the government whose level of default is zero

real risk-free rate=return on investment-inflation premium-default risk-liquidity premium-maturity premium

real risk-free rate=4.4%-1.9%-0%-0%-0.4%

real risk-free rate=2.1%

An astronaut decides to perform an experiment to monitor how much weight he loses during his stay on the International Space Sta
kumpel [21]

Answer:

The first one is: His weight on the Earth before take-off and the weight after take-off back on Earth once he gets back should be recorded as his Independent variable and his dependent variable.

The second one is: If he gained the weight back that he had lost while on the trip then you should disregard them unless that was the weight he was when he weighed himself after he got back.

The Third one is: The mass of an object is the amount of matter it contains, regardless of its volume or any forces acting on it. … Gravity is a force that attracts objects toward the Earth. The weight of the object is defined as the force caused by gravity on a mass.

Explanation:

I took  the quiz earlier. Hope this Helps you.

The fundamental frequency of a guitar string is 367 hz . part a what is the fundamental frequency if the tension in the string i
ANTONII [103]
The fundamental frequency of a string is given by:
f_1 =  \frac{1}{2L} \sqrt{ \frac{T}{\mu} }
where L is the string's length, T the tension and \mu the linear density of the string.

We can see that f1 is proportional to the square root of T: \sqrt{T}.
This means that if the new tension is half the initial value, the new fundamental frequency will be proportional to \sqrt{ \frac{T}{2} }= \frac{ \sqrt{T} }{ \sqrt{2} }=  \frac{f_1}{ \sqrt{2} }

So, the new fundamental frequency will be
f_1 ' =  \frac{367 Hz}{ \sqrt{2} }=259.5 Hz

A ball that is attached to a string travels in a horizontal, circular path, as shown in Figure 1. At time t0 , the ball has a sp
Levart [38]

Answer:

F₁ = 4 F₀

Explanation:

The force applied on the string by the ball attached to it, while in circular motion will be equal to the centripetal force. Therefore, at time t₀, the force on ball F₀ is given as:

F₀ = mv₀²/r   --------------- equation (1)

where,

F₀ = Force on string at t₀

m = mass of ball

v₀ = speed of ball at t₀

r = radius of circular path

Now, at time t₁:

v₁ = 2v₀

F₁ = mv₁²/r

F₁ = m(2v₀)²/r

F₁ = 4 mv₀²/r

using equation (1):

<u>F₁ = 4 F₀</u>
