A uniform electric field contains a number of particles. All are experiencing forces in the same direction as the electric field
myrzilka [38]

Answer: D

All the particles must be uncharged

Explanation:

If all the particles are positively charged, then there will be force of repulsion between them which will give different directions away from each other. The same is applicable if they are all negatively charged.

If the particles are positively and negatively charged, their will be force of attraction between them which will give different directions towards each other.

For all to be experiencing forces in the same direction, We can conclude that

All the particles must be uncharged.

A striped billiard ball moves toward the right with speed 3 m/s. A solid billiard ball with the same mass moves toward the left
Helen [10]

Answer:

Final speed of striped ball is 3 m/s in left direction .

Explanation:

Given :

Two billiard ball with the same mass moves toward the left at the same speed 3 m/s .

Let , us assume right hand side direction to be positive and left hand side direction to be negative .

Also , let speed of ball after collision is (striped ball ) u and (solid ball) v .

It is also given that the collision is elastic .

Therefore , kinetic energy is conserved .

\dfrac{m(3)^2}{2}+\dfrac{m(3)^2}{2}=\dfrac{mu^2}{2}+\dfrac{mv^2}{2}\\\\u^2+v^2=18 ...... ( 1 )

Also , by conserving linear momentum .

We get :

3m-3m=mu+mv\\u=-v                ...... ( 2 )

Putting value of u from equation 2 to equation 1 .

We get :

2v^2=18\\v=3\ m/s

And , u = -3 m/s .

Therefore , final speed of striped ball is 3 m/s in left direction .

Hence , this is the required solution .

In addition to plate tectonics, what is the other main driving force of the rock cycle?
GREYUIT [131]

Answer:  Option B

Explanation:

Rocks contains pores and spaces in them in which water gets trapped, and this causes the rock to break as water increases its volume due to freezing. This rocks are then eroded and are carried away into the streams and channels. The rivers and streams can carry particles of various shapes and size, which are further transported and deposited at a different place.

This particles or sediments then gets compacted and lithified in due course of time, and forms sedimentary rocks.

Water is also needed to undergo metasomatism process, that creates a metamorphic rock.

Hence, water flow is also an important driving force in rock cycle, along with tectonic activities.

Thus, the correct answer is option (B).

if the outside air temperature increases during a flight at constant power and at a constant indicated altitude, the true airspe
Mazyrski [523]

If the outside air temperature increases during a flight at constant power and at a constant indicated altitude, the true airspeed will Increase and true altitude will increase.

<h3>What is Altitude?</h3>

This refers to the vertical elevation of  a body and is the measurement of the height above the sea or ground level. An airplane's altitude is directly proportional to the airspeed as long as the power is constant.

This means that increase in airspeed will lead to an increase in altitude and vie versa. This is the reason why as it runs fast, it can be observed that it begins to elevate.
