Susie walks 3 blocks north to the local CVS store, then 4 blocks east to her grandmother’s house. She then walks 2 blocks west a

nd 2 blocks north to Target. She then walks two blocks west and 1 block south to the pizzeria to pick up a couple of pizzas, then takes it to her friend’s house a block south of the pizzeria. What is Susie’s total displacement.?

Answer:

Suzie is 3 blocks north of where she started

Explanation:

Displacement is the minimum distance between the initial and final point of motion.

Here, Suzie first walks 3 blocks north. From there she walks 4 blocks east. Then 2 blocks to the east then 2 blocks north and then 2 blocks east. She covered 4 blocks east toward west. This is the same distance she covered traveling east. But she is 2 blocks north. From there she traveled a block south to the pizzeria and another block to her friends house. She covered the two block she had traveled north.

Hence, Suzie is 3 blocks north of where she started.

You have a resistor and a capacitor of unknown values. First, you charge the capacitor and discharge it through the resistor. By
Fittoniya [83]

Answer:

The frequency is    f  = 0.221 \ Hz

Explanation:

From the question we are told that  

     The  time taken for it to decay to half its original size is t  =  3.40 \ ms  =  3.40 *10^{-3} \ s

Let the voltage of the capacitor when it is fully charged be  V_o

Then the voltage of the capacitor at time t is  said to be  V  =  \frac{V_o}{2}

   Now  this voltage can be  mathematical represented as

      V  =  V_o  * e ^{-\frac{t}{RC} }

Where  RC  is the time constant

   substituting values  

    \frac{V_o}{2}  =  V_o  *  e ^{-\frac{3.40 *10^{-3}}{RC} }

    0.5  =  e^{-\frac{3.40 *10^{-3}}{RC} }

    - \frac{0.5}{RC}  =  ln (0.5)

     -\frac{0.5}{RC} =  -0.6931

     RC  =  0.721

Generally the cross-over frequency for a low pass filter is mathematically represented as

          f  = \frac{1}{2 \pi  * RC  }

substituting values  

           f  = \frac{1}{2*  3.142  * 0.72  }

           f  = 0.221 \ Hz

Researchers interested in studying stress gave 150 high school seniors a very difficult math exam. After the test, the researche
belka [17]

Answer:

<u>Informed Consent- The study didn't conform this ethical standard.</u>

<u>Debriefing- The study conforms this ethical standard.</u>

<u>Confidentiality- The study conforms this ethical standard.</u>

<u>Protection from harm- The study conforms this ethical standard.</u>

Explanation:

<u>Informed consent</u> is described as a procedure whereby researchers tend to provide details about specific research they are going to conduct, the risk & benefits involved in the study, different alternatives involved in the procedure, etc.

<u>Debriefing </u>is described as a process that is being conducted in any of the different psychological research encompassing human participants after specific research is completed. The researcher tends to describe the details of the research to the participants.

<u>Confidentiality</u> is described as one of the different code of ethics followed by health workers or psychologists. While practicing confidentiality, a psychologist tends to promise his or her participants that he or she will keep everything a secret whatever is being discussed or shared between both of them.

<u>Protection from harm</u> determines that the psychologists conducting research follows the ethics in which he or she has to protect all the participants from any kind of harm.

A 225 kg red bumper car is moving at 3.0 m/s. It hits a stationary 180 kg blue bumper car. The red and blue bumper cars combine
Alex Ar [27]

Given


m1(mass of red bumper): 225 Kg


m2 (mass of blue bumper): 180 Kg


m3(mass of green bumper):150 Kg


v1 (velocity of red bumper): 3.0 m/s


v2 (final velocity of the combined bumpers): ?




The law of conservation of momentum states that when two bodies collide with each other, the momentum of the two bodies before the collision is equal to the momentum after the collision. This can be mathemetaically represented as below:


Pa= Pb


Where Pa is the momentum before collision and Pb is the momentum after collision.


Now applying this law for the above problem we get


Momentum before collision= momentum after collision.


Momentum before collision = (m1+m2) x v1 =(225+180)x 3 = 1215 Kgm/s


Momentum after collision = (m1+m2+m3) x v2 =(225+180+150)x v2

=555v2

Now we know that Momentum before collision= momentum after collision.


Hence we get


1215 = 555 v2


v2 = 2.188 m/s


Hence the velocity of the combined bumper cars is 2.188 m/s
