Answer:

Motion maps are used to illustrate the direction and position of an object. Using the motion map, the description of the object position and velocity is as follows:

The object starts its movement from the origin with a large velocity, before moving back to the origin with a smaller velocity. It stops for 1 second in the origin, then moves away with a larger velocity, Finally, it moves back towards the origin with a smaller velocity.

See attachment for the motion map, where the number on each arrow in the map, represents the position of the object.

Note that; the long arrow means large velocity while the short arrow means small velocity

Next, we analyze the direction and position using the arrows

The first arrow shows that the object starts from the origin with a large velocity

The direction and length of the second arrow show that, the object then returned to the origin with a smaller velocity.

There is a dot in front of the second arrow. This dot indicates that the object stops for one second.

The third arrow means that, the object moved from the origin with a larger velocity

The direction and position of the fourth and fifth arrows indicate that the object then moves towards the origin, with a smaller velocity.

An object 5.Ocm in the length is placed at a distance of 20cm in front of convex mirror
andrew-mc [135]

Answer:

Position = \frac{60}{7}\ cm behind the mirror

Nature = Virtual and Erect

Size = \frac{15}{7}\ cm : Diminished

Explanation:

Sign convention-Distance measured to the left of pole is negative and to the right of pole is positive.

Object distance = u = -20 cm

Focal length = f = Radius of curvature/2 = 30/2 = 15 cm

We have to use mirror formula to find image distance.

\frac{1}{u}+\frac{1}{v}=\frac{1}{f}\\ \frac{1}{-20}+\frac{1}{v}=\frac{1}{15}\\ \frac{1}{v}=\frac{7}{60}\\v=\frac{60}{7}\ cm

Since the image distance is positive, it is formed behind the mirror or a virtual image is formed.

Magnification = =\frac{h_{image}}{h_{object}}=-\frac{v}{u}=\frac{60}{7\times20}=\frac{3}{7}

Height of the object = 5 cm

Height of the image = 5\times\frac{3}{7}=\frac{15}{7}\ cm

Since the height of the image is positive and less than the size of object,it is erect and diminished.

Do you think toxicity is a qualitative or quantitative property? explain
Tomtit [17]

Answer:

<u>Toxicity is a quantitative property</u>

Explanation:

  • Qualitative property of a object cannot be measured it can just be observed
  • Quantitative property of a substance  can be measured and be assigned a numerical value .
  • <u>The toxicity level of a substance can be measured and be assigned a numeral value </u>
