Y_Kistochka [10]

Answer:

C)focusing on one goal at a time

Explanation:

Self-modification programs could be regarded as a program that help individual in managing unwanted as well as dysfunctional behavioral responses whenever they are going through a problem and try to deal with it. For instance the dysfunctional behavioral response for someone with a panic attack is avoidance. Some of the the steps that are involved in in a self-modification program are;

✓ specifying target behavior ✓designing a program

✓ gathering data about target behavior

uring the investigation of a traffic accident, police find skid marks 89.9 m long. They determine the coefficient of friction be

aivan3 [116]

Answer:

$V_{0}=29.68m/s$

Explanation:

In order to solve this problem, we must first do a drawing of the situation (see attached picture).

When the brakes of the car were applied, we can see that there was only one horizontal force affecting the vehicle's movement, which was the force of friction. When analyzing the free body diagram we can apply Newton's laws to determine the equations we will use to solve this.

$\sum F_{x}=ma$

so:

-f=ma

we also know that:

$f=N\mu_{k}$

$-N\mu_{k}=ma$

we can now solve for the acceleration, so we get:

$a=\frac{-N\mu_{k}}{m}$

we don't know what the normal force is, so we can find it out by analyzing the vertical forces applied to the car:

$\sum F_{y}=0$

so we get:

N-W=0

which means that:

N=W

we also know that:

W=mg

N=mg

we can substitute this into the first equation so we get:

$a=\frac{-mg\mu_{k}}{m}$

which simplifies to:

$a=-g\mu_{k}$

we can now substitute the provided data:

$a=(-9.8m/s^{2})(0.5)$

which yields:

$a=-4.9m/s^{2}$

once we got the acceleration, we can use kinematics formulas to solve this, we got the following formula:

$a=\frac{V_{f}^{2}-V_{0}^{2}}{2x}$

we know the final velocity must be zero, since that's where the car got to a stop, so the formula then becomes:

$a=-\frac{V_{0}^{2}}{2x}$

we can now solve for the initial velocity, which yields:

$V_{0}=\sqrt{-2xa}$

so we can now substitute the daa we know, so we get:

$V_{0}=\sqrt{-2(89.9m)(-4.9m/s^{2})}$

so we get:

$V_{0}=29.68m/s$

So from this we know that the velocity of the car must have been of at least 29.68m/s when the brakes were applied.

Describe the type of rock and it’s texture that would form from the melted meteorite and Earths rocks

Leto [7]

Igneous rocks are formed from solidification and cooling of magma. The magma can be obtanied from partial melts of pre-existing rocks in either the planet's mantle or crust. Plutonic or intrusive rocks area result of when the magma cools and crystallizes slowly within the Earth's crust. A example is granite.
