Answer:

the most elliptical orbit is that of COMETA

Explanation:

The eccentricity of a curve in defined as the ratio between lacia to the focus, called c and the value of the axis greater than

         ε = c / a

if we use Pythagoras' theorem

         c = [tex]\sqrt{a^2 - b^2}[/tex]

   substituting

           ε = [tex]\sqrt{1 - (b/a)^2 }[/tex]

if   ε = 0 we have a circumference

In the diagram presented the orbit of the comet is an ellipse a> b

          ε=[tex]\sqrt{1- x} \\ x = (\frac{b}{a} )^2[/tex]

if we expand in series

             ε = 1 - x/2  

             ε=  [tex]1 - \frac{1}{2} \ (\frac{ b}{a} )^2[/tex]

if we neglect the non-linear terms

            ε = 1

Earth's orbit is a small ellipse

             b / a = 149 10⁶ / 151 10⁶

             b / a = 0.98675

             ε = [tex]\sqrt{1- 0.98675^2}[/tex]

               ε = 0.16

a very small ellipse

Planet X, despite not having data, it seems that the sun is in the scepter of the orbit, so b = a

therefore  both the semi-axes of the curve

        e = a / b

Consequently, the most elliptical orbit is that of COMETA.

The answer to the question is logic

Answer:

Resistance = 252.53 Ohms

Explanation:

Given the following data;

Charge = 0.125 C

Voltage = 5 V

Time = 6.3 seconds

To find the resistance;

First of all, we would determine the current flowing through the battery;

Quantity of charge, Q = current * time

0.125 = current * 6.3

Current = 0.125/6.3

Current = 0.0198 A

Next, we find the resistance;

Resistance = voltage/current

Resistance = 5/0.0198

Resistance = 252.53 Ohms

Answer:

The correct option is (c).

Explanation:

The electrostatic force between charges is given by :

[tex]F=k\dfrac{q_1q_2}{r^2}[/tex]

Where

r is the distance between charges

If the distance between two electric charges is tripled, r' =3r

New force becomes,

[tex]F'=k\dfrac{q_1q_2}{(3r)^2}\\\\F'=k\dfrac{q_1q_2}{9r^2}\\\\F'=\dfrac{1}{9}\times k\dfrac{q_1q_2}{r^2}\\\\F'=\dfrac{F}{9}[/tex]

So, the new force becomes 1/9 of the original force. The correct option is (c).

No one can know the size of the universe, it may in fact be infinitely large.

Explanation:

No one knows the size of the universe because we can't see the entire universe. We can only see the part that is close enough to us that there has been time for the light from it to arrive here. What that means is any part of the universe that it will take more than 14.5 billion years for light to travel to us can not bee seen. It is possible that the universe has no size, that is it is infinite.

We can measure what we call the "visible universe" and that is a sphere around us with a radius of about 50 billion light years, the reason it is more than the age of the universe (14.5 billion years) is because the universe is expanding more rapidly than the speed of light.

The way scientists measure the size of the visible universe is with what is called red shift. Similar to the way a car horn's pitch changes as it passes you due to doppler shift, light too has a shift in is frequency or color depending on if it is moving away or toward you. As light moves away from you it shifts for red and the faster it is moving away the more it shifts. We can estimate the distance objects are away by how much they are red shifted. When we look at the most distance objects we can see they are about 50 million light years away.

Explanation:

I. The electric circuit shown is series and parallel resistor connection type.

II. The ratio of current in the 8-ohm resistors to the current in the 4-ohm resistors is 0.46.

III. The current in 8 ohm is less than the current in 4 ohm resistor.

IV. The ratio of current in the 3-ohm resistors and 8-ohm resistor to the current in the 10-ohm resistors is 1.

V. The current in 3 ohm and 8 ohm resistor is same.

The current is the total amount of charge flowing in the circuit per unit time.

3 ohm and 8 ohm resistor are in series which in turn parallel with the 10 ohm resistor.

The equivalent resistance of 3, 8 and 10 ohm resistor is in series with 9 an 4 ohm resistors.

I. The circuit consists of resistances connected in parallel and series also.

II.  The equivalent resistance of 3, 8 and 10 ohm resistor is [(3+8)x10/(3+8+10)] = 5.23 ohms.

Total equivalent resistance is 9 + 5.23 +4 = 18.23 ohms.

The Current in the circuit is

I= V/Req = 12/18.23

I = 0.65 A

The Current in the 8 ohm resistor is I₈ = 0.30 A

The Current in the 4 ohm resistor is I₄ =0.65 A

Their ratio  I₈/I₄ = 0.46

Thus, the ratio of current in the 8-ohm resistors to the current in the 4-ohm resistors is 0.46.

III. The current in 8 ohm is less than the current in 4 ohm resistor.

IV. Current in the 8 ohm resistor is I₈ = 0.30 A

Current in the 3 ohm resistor is I₃ = 0.30 A

Their ratio  I₃/ I₈ = 1

Thus, the ratio of current in the 3-ohm resistors and 8-ohm resistor to the current in the 10-ohm resistors is 1.

V. The current in 3 ohm and 8 ohm resistor is same.

Answer:

Explained below.

Explanation:

Newton's first law of motion states that an object will continue in its present state of rest or continue with constant speed in a straight line except it is acted upon by an external force.

For every object in motion or at rest there is a force of friction that tries to resist its motion or prevent it from moving with constant velocity.

Now, to push it from rest you will need to apply a force large enough to overcome its static friction. Now, after that initial motion, smaller forces will have to be applied to overcome what is called sliding friction that prevents the crate from sliding which will affect the constant velocity.

Answer:

(iii) 300m

Explanation:

(i) The velocity of the cyclist is constant with time, the rate of the change of the velocity with the time is zero. So the acceleration of the object will be zero.

(ii) According to the graph we observe that the cyclist is moving with the same velocity all the time, therefore, the velocity of the cyclist is [tex]20m/s^{-1}[/tex]

(iii) Apply the formula: (speed = velocity x time)

s = vt

s = [tex]20m/s^{-1}[/tex] x 15s

s = 300m

Explanation:

Answer:

Two 50 Ohm Resistors, One 20 Ohm Resistor.

Explanation:

For the given current and voltage specifications, the resistance can be calculated by Ohm's Law:

[tex]V = IR\\\\R = \frac{V}{I}[/tex]

where,

R = Resistance = ?

V = Voltage = (1.5 V)(4) = 6 V

I = 0.05 A

The heat absorbed can be calculated using calorimetric equation. The heat absorbed by the copper block of mass 0.500 kg for the temperature difference of 290 to 400 degree Celsius is 2.13 E4 J.

Calorimetry is an analytical tool used to determine the heat energy absorbed or released by a system. The calorimetric equation connecting the mass m, temperature difference ΔT and specific heat capacity c is given by:

q = m c ΔT .

Given,

m = 0.500 kg

c = 387 J/(kg °C )

ΔT = 400 - 290 °C = 110°C.

Then, the heat energy absorbed by the copper block is ;

q = 0.50 kg × 387 J/(kg °C ) × 110°C

  =  2.13 E4 J

Therefore, option E is correct.
