Part F: Creating and Delivering a Presentation Using the materials you've gathered, create your presentation. It should include 15 slides and be 5 to 10 minutes long, Be
sure to proofread and revise your writing to catch any errors in grammar, spelling, logic, or organization. Add the
speaker's notes and a works cited page at the end to give credit to your sources. Submit your completed presentation
along with this activity to your teacher for evaluation,
If required by your teacher, deliver your presentation to an audience. Be sure to rehearse your presentation before you
deliver it and ensure that you complete it within the time limits (5-10 minutes), When presenting, speak clearly and
maintain eye contact with your audience.
If your teacher is unable to attend your presentation, record it. PowerPoint enables you to record a video. Submit the
completed video to your teacher along with this activity.

Answer from: Quest

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

$f\alpha \frac{dp}{dt}$

⇒ $f= k \frac{dp}{dt}$

here k is the proportionality constant whose value is 1.

$f=\frac{dp}{dt}$

$f= \frac{d[mv]}{dt}$

$f= m\frac{dv}{dt} +v\frac{dm}{dt}$

$f=ma+v\frac{dm}{dt}$ [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

Sorry i don’t know what to do

Answer from: Quest

You need to be more specific. i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time, then constant velocity is a straight line . . i.e. a line that has constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant velocity is a piece of line that lies on the x-axis . . it's value is zero.

An insulated thermos contains 148 g of water at 72.7 ˚c. you put in a 11.7 g ice cube at 0.00 ˚c to form a system of ice + original water. the specific heat of liquid water is 4190 j/kg•k; and the heat of fusion of water is 333 kj/kg. what is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?
