Explanation:

An object which moves 10 km in 30 minutes .

we have to find the average speed of the object .

Changing unit of time into hour

Time = 30/60 hour

Time = 1/2 hour

Time = 0.5 hour

Now let's calculate the average speed

Put the value we get

So, the average speed is 20km/hr

Changing unit of time into hour

Time = 30/60 hour

Time = 1/2 hour

Now let's calculate the average speed

$\rm\bf \: Average \: speed \: = \frac{Total \: distance}{Total \: time \: }$

Put the value we get

$\dashrightarrow \sf \: Average \: speed \: = \frac{10}{0.5} \\ \\ \dashrightarrow \sf \: Average \: speed \: = \frac{100}{5} \\ \\ \dashrightarrow \sf \: Average \: speed \: = \cancel \frac{100}{5} \\ \\ \dashrightarrow \sf \: Average \: speed \: =20km {hr}^{ - 1}$

So, the average speed is 20km/hr

What is the average speed of an object that moves 100 m in 4 seconds and then remaining at rest for 1 second?

Step-by-step answer

P Answered by PhD

During the first 4 seconds, its average speed is (100/4) = 25 m/s .

During the full 5 seconds, its average speed is (100/5) = 20 m/s .

The measurement of how fast an object moves over a certain amount of time. question 1 options: speed acceleration displacement velocity which of the following depends on an object s displacement not distance from the starting point? question 2 options: acceleration displacement speed velocity what is the average speed of an object that travels 50 miles in 2 hours? question 3 options: 25 mph 50 mph 100 mph 2 mph which of the following is an example of velocity? question 4 options: 100 mph 25 east 50 mph east 100 miles east which of the following

Step-by-step answer

1. Speed, since we know that $s=\frac{d}{t}$ , where s is speed, d is distance and t is time

2. Velocity, for velocity you need to consider the direction and displacement gives the direction of travel.

3. 25 mph, because $s=\frac{d}{t} =\frac{50}{2} =25mph$

4. 50 mph east, velocity unlike speed has direction.

5.Velocity, displacement gives the formula $v=\frac{d}{t}$ direction.

6. 0, the displacement is zero so velocity is zero

7. It decreases, speed is inversely proportional to time

17. A distance-time graph indicates that an object moves 120 meters in 5 seconds and then remains at rest for 5 seconds. What is the average speed of the object?

Step-by-step answer

P Answered by PhD

12 m/s

Explanation:

Speed is distance moved per unit time and expressed as

S=d/t

S is speed, d is distance and t is time.

When at rest for five minutes, distance moved is zero hence speed is 0/5=0 m/s

When having moved 120 m for 5 s then speed is

S=120/5=24 m/s

Average speed is the average of these two speeda

Average speed=(24+0)÷2=24/2=12 m/s

Therefore, average speed is 12 m/s

A distance time graph indicates a car moves 200 m in 8 s then remains at the rest for 2s what is the average speed of the object (hint: use the formula to calculate speed, add all vectors (8s + 2s) ANF answer using units m/s) please I really need help :(

Step-by-step answer

20 m/s

Explanation:

Average speed = distance / time

v = 200 m / (8 s + 2 s)

v = 20 m/s

a. Create a “rough copy” tree. and use numbers for the creatures, and write out the characteristics. You will use this draft to make the next cladogram. The idea is that you may need to make changes as you go. This tree is not expected to be the finished product, and may be done with pencil.
b. Create a “good copy” cladogram for the creatures. the characteristics must be labeled on the tree.

Your answer should include

clear drawn rough copy” tree

a good copy cladogram

Do not use —— or + to draw trees or cladogram please draw them instead.
