How many ""accelerators"" do you have in your car? There are three ways to change the velocity of a car and there are three corr

esponding controls in the car that allow you to make each of these changes. What are the three different controls and what kind of acceleration does each one produce? Remember to think both about changes to the magnitude of acceleration and to the direction of acceleration.

Answer:

The three "accelerators"  are: the throttle,  the steering wheel and the brakes.

Explanation:

Acceleration means change in velocity. But this change may be in module or in direction.

Car throttle will increase the  velocity module of the car and brakes wil diminish it. On the other hand, the steering wheel will change the direction of the velocity.

Hope my answer helps you.    Have a nive day!

If all the stars in an elliptical galaxy traveled random directions in their orbits, the elliptical galaxy would be type
Lemur [1.5K]

The answer would be E7. Galaxies categorized as E0 look to be nearly perfect, while those registered as E7 seem much extended than they are widespread. It is worth noting, though, that a galaxy's look is connected to how it lies on the sky when viewed from Earth. An E7 galaxy is very long and thin or the flattest of them all.

Where should be the best fit line be drawn on a scatterplot?
eimsori [14]

A line of best fit is a straight line drawn through the most points on a scatter plot, with an equal number of points above and below the line. It is used to investigate the nature of the relationship between two variables. The correct option is d.

<h3>What is line of best fit?</h3>

A straight line with the best fit is one that minimizes the distance between it and some data.

In a scatter plot of varying data points, the line of best fit is used to express a relationship. It is a result of regression analysis and can be used to forecast indicators and price movements.

It is important to note that your line does not need to pass through any of the points on the plot; it only needs to bisect the area that contains the data points.

Thus, none of the options are correct, the correct one is d.

A series-parallel circuit consists of two parallel circuits connected in series across a 45-V source. One parallel branch consis
musickatia [10]

Answer:

The answer to the question is

The current  through R4 = 0.5865 mA

Explanation:

To solve this we list out the known thus

Voltage source = 45-V

Firsrt parallel circiuit has resistances of R1  = 17 kΩ and R2 = 23 kΩ

Second parallel circiuit has resistances of R3  = 45 kΩ and R4 = 55 kΩ

we first find the current flowing in the circuit by finding thr sum of the total resistance in eah parallel circuit

Firsrt parallel circiuit, for circuit in parallel, sum of resistance 1/RT1 = 1/ R1 + 1/R2 = 1/17+1/23 =  0.1023017 therefore RT1 = 1/0.1023017 = 9.775 kΩ

Similarly we have for the second parallel circuit 1/RT2 = 1/R3 + 1/R4

= 1/45 + 1/55 =  0.0404 Hence RT2 = 1/0.0404 = 24.75 kΩ

This means that the 9.775 kΩ and the 24.75 kΩ are in series hence total resistance of the circuit = sum of all resistances in series  

= 9.775 kΩ + 24.75 kΩ = 34.525 kΩ

However current, I is given by V/R = 45-V/34.525 kΩ = 1.303 × 10⁻³ A or 1.303 mA

From the current divider rule, I4 = I × (R4/(R3+R4)

That is the currrent flowing throuhgh R4 = 1.303  × (45/(45+55)) = 0.5865 mA
