mass and acceleration if force is constant?

Answer:

Enlarged brain ventricles are presumed to signify

____a deterioration of brain tissue____.

Explanation:

got it right

Enlarged brain ventricles are presumed to signify a deterioration of brain tissue. The correct option is D.

One or more of the ventricles swell as CSF builds up when an injury or sickness disrupts CSF circulation. Because the adult skull is stiff and cannot expand, the pressure inside the brain may significantly rise.

A chronic illness known as hydrocephalus causes fluid to accumulate in the ventricles deep inside the brain. It normally cannot be cured, but it can be controlled.

As a neurodegenerative disease that causes cognitive impairment and behavioral abnormalities, Alzheimer's disease is a progressive illness that impairs memory and other critical mental functions.

Therefore, the correct option is D. A deterioration of brain tissue.

Answer:

When the Sun, the Earth, and the Moon are all aligned in space, a lunar eclipse occurs. The Moon reflects the Sun's light onto the Earth. The Earth gets in the way of the Sun in this case, keeping sunlight from reaching the moon. A lunar eclipse happens if this alignment is ideal.

Answer:

B. The kinetic energy of the ball change into potential energy as the ball rises.

Explanation:

This can seem a little bit confusing at first, but once you understand Kinetic Energy, you'll get it right away. Kinetic Energy is energy an object has when it is moving. So for example, you have kinetic energy when you run, a pen has kinetic energy when you drop it in class, and the ball has kinetic energy as it rises.

However, because of outside forces, objects with kinetic energy will eventually lose it. These forces can be anything from friction as an object slides across a surface, to the negative acceleration due to gravity.

In this question, the force working against the motion of the ball is gravity. As you know, when you throw something up, it has to come down, because of gravity. As the ball goes up, it has enough kinetic energy that it continues its upward motion, however it slowly looses that energy, causing it to slow to a stop before falling back to the ground.

On the way up, the energy of the ball changes from this kinetic (moving energy) to what we call potential energy. Potential energy is exactly what is sounds like, it is the potential for something to begin moving. So, as the ball goes higher, it has a lower chance of continuing to go up (meaning it's loosing it's kinetic energy) and higher chance of falling back down (meaning it's gaining potential energy).

Hope this helps.

For an object to move in a uniform motion it has to have either a constant velocity or a constant acceleration. If the object has a constant velocity then it is moving at zero acceleration and this means moving with out slowing down or speeding up.

Given parameters:

Duration of crash = 9min

Velocity before crash = 2000 yards per second

Unknown:

Acceleration of the plane = ?

Solution:

Acceleration is the change of velocity with time.

  Acceleration  = [tex]\frac{V - U}{t}[/tex]

where v is the final velocity

          u is the initial velocity

          t is the time taken

We need to convert the time into seconds from min;

                      60s  = 1 min

                                So, 9min = 60 x 9 = 540s

So input the parameters and solve;

                  Acceleration = [tex]\frac{2000 - 0 }{540}[/tex]  = 3.7yards/s²

The acceleration of the plane is 3.7yards/s²

If a space rover has a mass of 3900 kg on Earth, then its mass when it lands on Mars will be the same i.e. 3900 kg.

Mass is the amount of matter present in the object.

The mass of the object is always constant, anywhere it is on the Earth or Moon or any other planet.

Thus, If a space rover has a mass of 3900 kg on Earth, the mass on Mars when it lands will be 3900kg.

What is wrong with the diagram is : ( 4 )

The maximum gravitational potential energy is located at the highest peak which the roller coaster attains while as the roller coaster comes down from the peak the gravitational potential energy decreases while the kinetic energy increases.

The point at which the roller coaster should attain it maximum kinetic energy should be at the lowest point ( i.e far left side of the bottom ).

Hence we can conclude that error in the diagram is the spot with the "maximum kinetic energy" should be on the lowest point of the roller coaster at the far left side on the bottom.

Answer:

10 m/s

Explanation:

vi = 70 m/s

a = -1.5 m/s²

t = 40 s

vf = vi + at

= 70 + (-1.5 x 40)

= 10 m/s

The final velocity will be "10 m/s".

Given:

Initial velocity,

Deceleration,

Time,

As we know,

→ Final velocity, [tex]v_f = v_i+at[/tex]

By substituting the values, we get

                               [tex]= 70+(-1.5\times 40)[/tex]

                               [tex]= 70+(-60)[/tex]

                               [tex]= 70-60[/tex]

                               [tex]= 10 \ m/s[/tex]

Answer:

s ≈ 35.8 m

Explanation:

Let's apply the uniform acceleration equation to find the vertical height travelled after 2.7 seconds.

[tex]s = ut + \frac{1}{2}at^2[/tex]

s = distance travelled

u = initial vertical velocity

t = time taken

a = gravitational acceleration

The gun is fired horizontally, hence there is no initial vertical velocity.

[tex]s = 0(2.7) + \frac{1}{2}(9.81)(2.7)^2[/tex]

[tex]s = 35.75745 m[/tex]

s ≈ 35.8 m

Answer:

The person has to move at the speed of 2.30 m/s towards the dropping point to catch the box.

Explanation:

Let t be the time taken by the box to reach the ground and v be the speed of the person on the ground standing 10 m away from the dropping

point.

As distance=(speed) x (time), so

[tex]10=vt\cdots(i)[/tex]

Initially, the height of the box from the ground is 92.4 m.

So, the displacement, s, covered by the box when it reached the ground,

[tex]s=92.4[/tex] m in the downward direction.

The gravitational force action of the box is also in the downward direction.

The initial velocity of the balloon, u=0.

According to the equation of motion,

[tex]s=ut+\frac1 2 at^2[/tex]

where a is the acceleration, u is initial velocity and.

Here, [tex]a=g=9.81 m/s^2[/tex] (acceleration due to gravity) and s and a are having the same direction.

So, on putting the values in the equation, we have

[tex]92.4=0\timest+ \frac 1 2 (9.81)t^2[/tex]

[tex]\Rightarrow t^2=\frac{92.4\times 2}{9.81}[/tex]

[tex]\Rightarrow t=\sqrt{\frac{92.4\times 2}{9.81}}[/tex]

[tex]\Rightarrow t=4.34[/tex] seconds.

So, the time available for the man on the ground to catch the bot is 4.34 seconds.

Now, from equation (i),

[tex]10=v\times 4.34[/tex]

[tex]\Rightarrow v = 10/4.34[/tex]

[tex]\Rightarrow v = 2.30[/tex] m/s.

Hence, the person has to move at the speed of 2.30 m/s towards the dropping point to catch the box.

Difference Between Gravitation and Gravity

Gravitation is referred to the force acting between two bodies which can be represented as the F=(GM1M2)/R2 which means gravitation force is proportional to the product of the masses of the object 1 and object 2 and is inversely proportional to the square of the distance between them. The gravitational force between earth and any object is known as gravity.

Difference Between Gravitation and Gravity

Gravitation Gravity

It is a universal force It is not a universal force

It is a weak force It is a strong force

The force is F=(GM1M2)/R2 (G= gravitational constant) The force is F=mg (g=acceleration due to gravity)

The direction of gravitational force lies in the radial direction from the masses The direction of the force of gravity is along the line joining the earth’s center and the center of the body. Its direction is towards the center of the earth.

The force can be 0 when the separation between bodies is infinity The force of gravity can be 0 at the center of the earth

It requires two masses It requires only one mass
