Peer assessment is a unique educational model. Think back to how you felt about peer assessment at the beginning of the term, an

luda_lava [24]

Answer:

In the beginning, I was not familiar to assess assessments of the other students. Ifelt a little bit weird that is it possible to check assignments while having an instructor.I was also a bit frustrated, to be honest, that why do we have to assess thoseassessments. It was kind of extra burden for me. But after few weeks assessingmore assignments, my feeling had changed because I was learning lots of thingsthat were changing my perspectives. I was gaining extra knowledge from my peersin the form of assessments. Yes, I am comfortable with assessing assessments,because I got to learn many vocabularies and making structures of the sentencecorrectly by improving grammatically as I am not a native English speaker. Thus, inthis way, I was learning something new in each and every assessment.

A 500 kg object is hanging from a spring attached to the ceiling. If the spring constant in the spring is 900 N/kg, how far does

My name is Ann [436]

We are given that a 500 kg object is hanging from a spring. To determine the amount the spring is stretched we will use Hook's law, which states the following:

$F=kx$

Where:

$\begin{gathered} F=\text{ force} \\ k=\text{ spring constant} \\ x=\text{ distance stretched} \end{gathered}$

Since the object is hanging the only force acting on the spring is the weight of the object. The weight of the object is:

$F_g=mg$

Where:

$\begin{gathered} m=\text{ mass} \\ g=\text{ acceleration of gravity} \end{gathered}$

Plugging in the values we get:

$F_g=(500\operatorname{kg})(9.8\frac{m}{s^2})$

Solving the operations:

$F_g=4900N$

Now we solve for "x" from Hook's law by dividing both sides by "k":

$\frac{F}{k}=x$

Now we plug in the known values:

$\frac{4900N}{900\frac{N}{m}}=x$

Solving the operations:

$5.4m=x$

Therefore, the spring is stretched by 5.4 meters.

The distance covered by a car moving with a speed of 36 km/h in 15m is (a) 0.9 km (b) 9.0 km (C) 90 km (d) 900 km

GuDViN [60]

This is a uniform rectilinear motion exercise.

To start solving this exercise, we obtain the following data:

<h3>Data:</h3>

v = 36 km/h
d = ¿?
t = 15 min = 0.25 hr

Minutes to hour converter

60 min = 1 hour

$\boldsymbol{\sf15\not{min}*\dfrac{1 \ hr}{60 \not{min}}=0.25 \ hr }}$

To calculate distance, speed is multiplied by time.

We apply the following formula: d = v * t

We substitute our data into the formula:

$\boldsymbol{\sf{d=v*t}}$

$\boldsymbol{\sf{d=36 \dfrac{km}{\not{h}}*0.25 \not{h} }}$

$\boldsymbol{\sf{d=9 \ km}}$

The distance traveled by a car moving with a speed of 36 km/h in 15 m is 9 km.

Therefore, the correct option is "B".
