A constellation is _______ that forms a pattern resembling animals, mythological characters, or objects.
Svetradugi [14.3K]

A constellation is a group of stars.

Since human brains have evolved to look for patterns,
we sometimes seem to see patterns in groups of points. 
Different people make different pictures from the patterns ...
it depends on what they have on their mind.

Which of the following is NOT a characteristic of average speed?
solong [7]

Answer:

Therefore, the answer is: Option A.

Explanation:

  • The average speed is defined as the total distance traveled by an object divided into the time that it takes for the object to travel that distance.

 

  • Average speed is a scalar quantity, which means that it can be represented using a number with no need of specifying a direction. Since the total distance is a positive value, then average speed is always also a positive value.

 

From the options, the statement "average speed includes both rate of motion and its direction" is false.

An object is moving from north to south what is the direction of the force of friction of the object
aev [14]

Answer:

North

Explanation:

Friction is a reaction force against the direction of movement. So since the direction of movement is south the friction would be opposite and move north.

The drawing shows the electrical potential as a function
Ilia_Sergeevich [38]

Answer:

a)\quad E_{ab} = 0 \quad Volts/m\\\\b)\quad E_{bc} = 10 \quad Volts/m\\\\c)\quad E_{cd} = 5 \quad Volts/m

Explanation:

As figure is not given so considering the most relevant diagram for question attached below

We can define Electric field as rate of change of electric potential with respect to space (say x-axis here). It is related in formula as

E=-\frac{\Delta V}{S}---(1)

a) For Region A to B:

As can be seen from figure, point charge moves from 0 to 0.2 along x-axis, the value of electric potential remains constant i.e 5 volts

E_{ab}=-\frac{V_{b}-V_{a}}{b-a}\\\\E_{ab}=-\frac{5-5}{0.2-0}\\\\E_{ab}=0\quad Volts/m

b) For Region B to C:

As point charge moves from B to C (0.2 to 0.4) along x-axis, the value of electric potential decreases from 5 volts to 3 volts. Electric field induced is:

E_{bc}=-\frac{V_{c}-V_{b}}{c-b}\\\\E_{bc}=-\frac{3-5}{0.4-0.2}\\\\E_{bc}=10\quad Volts/m

c) For Region C to D:

As point charge moves from C to D (0.4 to 0.8) along x-axis, the value of electric potential decreases from 3 volts to 1 volt. Electric field induced is:

E_{cd}=-\frac{V_{d}-V_{c}}{d-c}\\\\E_{cd}=-\frac{1-3}{0.8-0.4}\\\\E_{cd}=5\quad Volts/m

For Information:

Unit of Electric field is V/m or N/C
