Extra Points because there are three questions.

1. An object goes from 20 m/s to 5 m/s in 1.2 seconds. What is the acceleration of the object?

a=vf-vi/t

2. What is the difference between distance and displacement? What is the difference between mass and weight?

3. What is the force necessary to accelerate a 40 kg object to 6 m/s/s?

F=ma

Answers

Answer 1

1. Change in velocity=5-20
Change in velocity=-15 (Deceleration)
Acceleration= change in velocity/time
a=-15/1.2
a=12.5m/s2

2. Distance has no magnitude and no direction but displacement has both magnitude and direction
Mass is constant but weight varies from places to places. Also, mass is the quantity of a substance contained in matter while weight is the force exerted by a body

3. Force=ma
f= 40*6
f=240N

One equation that describes motion of an object is
x = vt + xo, where x is the position of the object, v is
its speed, t is time, and xo is the initial position. Show
that the dimensions in the equation are consistent.

Answers

We have that the resultant equation is L=L we can say that the dimensions in the equation are consistent

From the Question we are given equation

[tex]x = vt + xo[/tex]

Generally

x = distance in meters(m)

v =velocity in m/s

t=time in secs

x_0=distance in meters(m)

Therefore

The Dimension of equation is

[tex]L=LT^{-1}*T+L\\\\L=L[/tex]

Hence, Given that the resultant equation is L=L we can say that the dimensions in the equation are consistent

If you touch the two probes together while the DMM is set to resistance, what will happen?
The meter will read 0 ohms
The meter will short circuit and trip a protective circuit
The meter will read infinite ohms (as high as its scale goes)
The meter will show the equivalent voltage of the meter's internal battery

Answers

If the meter's battery is good and the meter is working OK, it should read zero ohms.

Most meters have a little adjustment wheel on the side to SET the reading to exactly zero when the probes are touched together.

The ferry bobbed slightly as its doors lowered to allow the cars off the boat and another line up of cars, which had accumulated since the last trip, on. Sandeep remembered how, one time, he and Den rode their bicycles to the ferry and crossed to the small mainland town on the other side. He yelled for Den to stop, "Hey, Den! I'm sorry, and I didn't mean it!" Den stopped and looked back him with eyes full of salty tears. Sandeep rode up to him and continued, "I'm really sorry about what I said to you there. I just don't know how to react to this. I mean, you're my best friend, and we do everything together."Den's face softened as his tears began to dry while he spoke, "It's okay, Sandeep. I'm upset about it, too, but if you would have let me talk earlier, I could have told you that we are still going to be going to the same school every day. My family bought a cottage on the island, so we can vacation here every summer. We are just moving to the mainland on the other side because Dad wants to cut waiting for the ferry from his trip. We'll be just a short ferry ride away. Do you remember that time when we rode our bikes to the ferry? Well, we can do that again, and as we get older, we can probably just meet up on either side all the time. It won't be too bad."At this news, a smile grew across Sandeep's face. "Well, why didn't you say so in the first place?" he laughed. Den began to laugh as well as the two boys looked across the water to the other side. "Well," Den said, "we'd better get moving." Sandeep looked confused. "Moving where?" he inquired with a worried look on his face. Den smirked as if he was about to tell a joke, "Back to your house to finish our lunch, of course!" The boys rode back to Sandeep's house side by side and as inseparable as always.( question ) Select phrase from this excerpt that best supports the theme of the story.
