Suppose (for this statement only), that q is moved from the origin but is still within both the surfaces. The flux through both

surfaces remains unchanged. True False The area vector and the E-Field vector point in the same direction for all points on the spherical surface.True False The flux through the spherical Gaussian Surface is independent of its radius.True False The Electric Flux through the spherical surface is greater than that through the cubical surface.True False The E-Field at all points on the spherical surface is equal due to spherical symmetry.True False Suppose (for this statement only), that q is moved from the origin but is still within both the surfaces. The flux through both surfaces is changed.

Answer:

-True  - True  - true   - false -false - false

Explanation:

  • True The flow depends only on the charge into the surface, not on the relative position
  • True The two vectors are radial, so their relative direction  do not changes
  • True It just depends on the charge inside
  • False, it only depends on the charge, not on the form from the integration surface
  • False, because if it has a load inside it can be considered in the center, but if the load is outside the flow lines change direction with respect to the surface
  • False The flow depends only on the load inside, not on its position

Suppose that a car traveling to the west (-x direction) begins to slow down as it approaches a traffic light. Make a statement c
nata0808 [166]

Answer:

The car is decelerating and its acceleration is negative.

Explanation:

First thing to consider. The car traveling direction is not important to answer the question.

Second, there are two affirmations on each sentence. So, lets take definitions:

Deceleration: Reducing the acceleration, from one value to another. No matter if the acceleration for the moment is positive or negative.

Acceleration negative: the driver is applying a force to make speed=0, the sign of this force must negative in order for the car to stop, other way it will go faster. Acceleration is the change rate of speed, if the speed is going down, the total acceleration until cars stops must be negative.

If you apply an unbalanced force to this object it will ______. Mention all that will apply: change velocity, accelerate, change
Papessa [141]

Answer:

All of them: change velocity, accelerate, change position

Explanation:

We can answer this question by using Newton's second law:

F = ma

where

F is the net force on the object

m is the mass of the object

a is the acceleration

We notice that when there is an unbalanced force on the object, F\neq 0, and therefore

a\neq 0

whcih means that the object will accelerate.

But acceleration is the rate of change of velocity, v:

a=\frac{\Delta v}{\Delta t}

And so,

\Delta v \neq 0

which means that the object will change velocity.

If the object is changing velocity, this means that it is also moving: therefore, the position of the object must be changing, so also the option "change position" is correct.

Granite is uplifted by the movement of tectonic plates. It will most likely become _____.
hammer [34]
<h3><u>Answer;</u></h3>

Sedimentary rock

Granite is uplifted by the movement of tectonic plates. It will most likely become a <em><u>sedimentary rock</u></em>.

<h3><u>Explanation</u>;</h3>
  • Granite is an intrusive igneous rock that is coarse-grained and light-colored, mainly composed of feldspar and quartz.  It forms from the crystallization or the cooling of magma in the Earth's crust.
  • <em><u>When igneous rocks such as granite undergo weathering and erosion they form sediments that are deposited, then compacted and cemented by the movement of tectonic plates resulting to the formation of sedimentary rocks.</u></em>

Salsk061 [2.6K]

Answer:

20.996 m

Explanation:

Given:

Initial velocity, u=0 \textrm{ m/s}

Final velocity, v=12.4062 \textrm{ m/s}

Total time taken, t_{Total} = 7.13 s.

∴ Acceleration is given as,

a=\frac{v-u}{t_{Total}}=\frac{12.4062-0}{7.13}=1.74 m/s²

Now, using Newton's equation of motion, we find the displacement.

Displacement is given as:

s=ut+\frac{1}{2} at^{2}

Plug in 0 for u, 4.91257 for t and 1.74 for a. Solve for s.

This gives,

s=0+\frac{1}{2} \times 1.74 \times (4.91257)^{2}=20.996 \textrm{ m}

Therefore, the train's displacement in the first 4.91257 s of motion is 20.996 m.

A golfer hits a shot to a green. The ball leaves the club at a speed of 20 m/s at an angle 32° above the horizontal. It rises to
Daniel [21]

Answer:

16.96 m/s

Explanation:

It is the case of projectile motion in which the projectile fires from the ground and again it hit the ground.

The angle of projection is 32 degree and the velocity of projection is 20 m/s

he velocity at the maximum height is equal to the horizontal component of velocity which always remains constant as there is no acceleration along x axis.

Velocity at the highest point = u Cos 32 = 20 x Cos 32 = 16.96 m/s
