How do astronomers describe the scale of the universe?
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.

You push a heavy crate. At first it doesn't move. You push harder, and it finally starts to move, but you still have to exert some force to keep it moving at a constant velocity. Explain.
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.

0.125 C of charge flow out of a
5.00 V battery in 6.30 s. How
much resistance is attached to the
battery?
(Hint: What is the definition of current?)
(Unit = Ohm)
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
The velocity-time graph shows the motion of a truck. Find (i) its velocity , (ii) its acceleration and (iii) the distance covered by the cyclist in 15 seconds
no spam please and answer fast!
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

Calculate the electrical energy use of the microwave in 120 V circuit has 7.5 A current flow, if it used for 0.05 hours
Answer:
162 KJ
Explanation:
The electrical energy can be calculated using the formula
E = V×I×t
Where, V= voltage = 120 V
I is current in ampere = 7.5 A and t is time in seconds
1 hour = 3600 sec
Therefore, 0.05 hour = 3600×0.05 = 180 sec
Substitute the values in above equation find electrical power
E = 120×7.5×180
= 162000 J
= 162 KJ
Therefore, the electrical energy use of the microwave = 162 KJ

To keep cool in the summer months, you decide to design and build your own hand-held fan. The fan's electrical circuit will run off of 4 AA batteries (each with a voltage of 1.5 V) and must not exceed 0.050 A of current. You visit your local Radio Shack and find that resistors are sold in five varieties: 5 Ohm, 10 Ohm, 12 Ohm, 20 Ohm, 50 Ohm. Each resistor costs 8 cents. What set of resistors should you buy to minimize cost?
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
Therefore,
[tex]R = \frac{6\ V}{0.05\ A}\\\\R = 120\ \Omega\\[/tex]
Now, to minimize the cost we will buy the following set of resistors:
Two 50 Ohm Resistors, One 20 Ohm Resistor.
A block of copper with mass 0.500 kg is heated to 400. degrees Celsius from 290. degrees Celsius. The specific heat capacity of copper is 387 J/ (kg*C°). The heat absorbed by the copper block is
7.74 E5 J
7.74 E4 J
5.61 E4 J
2.13 E5 J
2.13 E4 J
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.
What is calorimetric equation?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.

the diagram below represents the orbits of earth, comet temple-tuttle, and planet x, another planet in out solar system. arrows on each orbit represent the direction of movement. which objects orbit would have and eccentricity close to 1?
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.
