There are only two times of the year when the Earth's axis is tilted neither toward nor away from the sun, resulting in a equal amount of daylight and darkness at all latitudes. These events are referred to as Equinoxes.The word equinox is derived from two Latin words - aequus (equal) and nox (night). At the equator, the sun is directly overhead at noon on these two equinoxes. How do the climatological temperature patterns follow the four seasons? The temperatures are pretty much the same when comparing early winter to late winter and pretty much the same when comparing early summer to late summer. However, late Fall is much colder than early Fall and late Spring is much warmer than early Spring. Why is that? The reason is linked to the changing of the solar sun angle during each season. In the Fall, the sun angle is always getting lower and in the Spring it is always getting higher. From this it would make sense that late Fall is much colder than early Fall and late Spring is much warmer than early Spring. In the winter, the sun angle is INCREASING and in the summer the sun angle is DECREASING. This fact causes temperatures to be pretty much the same when comparing early winter to late winter and pretty much the same when comparing early summer to late summer. The cumulative cooling of the ground and ocean is partially offset by an increasing sun angle in the winter and the cumulative warming of the ground and ocean is partially offset by a decreasing sun angle in the summer. This causes the Spring and Fall seasons to seem much quicker in duration than the Summer and Winter seasons.

From an apple tree 2 metres high, a 100g mass apple fell of the tree, what work did it do?
Answer:
When an apple falls from the tree to the ground, its energy of position (stored as gravitational potential energy) is converted to kinetic energy, the energy of motion, as it falls. When the apple hits the ground, kinetic energy is transformed into heat energy.

Each bat can produce different frequencies of ultrasound. Explain why this is useful if there are many bats hunting together.
Answer: Although low frequency sound travels further than high-frequency sound, calls at higher frequencies give the bats more detailed information--such as size, range, position, speed and direction of a prey's flight. Thus, these sounds are used more often.

B. electrical current
C. electrical potential difference
D. magnetic field strength
difference between sold and liquid
Explanation:
Solids have closely packed particles and vibrate about a fixed position, they also have a fixed volume.
liquid have close particles but which are able to move with a bit of kinetic energy, for this reason they have no fixed volume but take the volume of the container or vessel
A weight-lifter raises a 2000 N weight through a vertical height of 2.0m in 0.80 s.
What useful power does he develop in doing this?
A
800 W
B
3200W
с
4000 W
D
5000W
Answer:
D. 5000W
Explanation:
Given the following data;
Force = 2000N
Distance = 2m
Time = 0.8s
To find the power;
First of all, we would determine the workdone by the weightlifter
Workdone = force * distance
Workdone = 2000 * 2
Workdone = 4000N
Now, we can find the power using the formula;
Power = workdone/time
Substituting into the equation, we have
Power = 4000/0.8
Power = 5000 Watts

In order for a roller coaster to work, why does the hill the cart climbs need to be higher than the top of the loop?
Answer:
The concept of potential energy, often referred to as energy of position, is very simple: As the coaster gets higher in the air, gravity can pull it down a greater distance. ... The potential energy you build going up the hill can be released as kinetic energy — the energy of motion that takes you down the hill.
Potential energy, also known as energy of position, is a pretty straightforward idea. As the roller coaster rises in the air, gravity has a greater ability to pull it down.
What does the hill the cart climbs need?An easy illustration involves a stopped car at the summit of a hill. The car drives faster as it goes down the hill, which results in an increase in kinetic energy and a decrease in potential energy. The vehicle changes kinetic energy into potential energy as it ascends the hill.
They are higher up at the top of the hill, thus they have more potential energy. Moving down a slope transforms potential energy into kinetic energy, while moving up a hill transforms kinetic energy into potential energy.
Therefore, You can release the potential energy you accumulate while climbing a hill as kinetic energy, which is the energy of motion that propels you down the hill.

A book is sitting on a table. Which of the following is true about the table? O A. It is pushing up on the book. O B. It exerts no force on the book at all. O C. It is pulling down on the book. D. It can affect the mass of the book.
Answer:
yes it does exert a force, it pushes it up
Explanation:
this is called normal force
if it didn't exert a force the book would keep going down
according to newton every force has an equal amd opposite reaction
so the book exerts a force on the table and vice versa

Explanation:
F. A 50. A resistor (R2), and unknown resistor R2, a 120 Volt source, and an ammeter are connected in a
complete circuit. The ammeter reads 0.50 ampere (current).
R1
a. Determine the resistance of Rz.
R2
Complete question is;
A 50.-ohm resistor, an unknown resistor R, a 120-volt source, and an ammeter are connected in a complete circuit. The ammeter reads 0.50 ampere.
A) Calculate the equivalent resistance of the circuit shown.
B) Determine the resistance of resistor R shown in the diagram.
Answer:
A) R_eq = 240 Ω
B) R = 190 Ω
Explanation:
A) To get the equivalent resistance, we will use the formula;
R = V/I
Where;
V is Voltage
I is current
R is equivalent resistance
From the question, V = 120 V and I = 0.5A
Thus;
R_eq = 120/0.5
R_eq = 240 Ω
B) From the image, we see that the resistors are connected in series.
Formula for resistors in series is;
R = R1 + R2 +..... Rn
Thus;
240 = 50 + R
R = 240 - 50
R = 190 Ω
A) The equivalent resistance of the circuit shown will be 240 Ω.
B) The resistance of resistor R will be 190 Ω
What is resistance?Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.
The given data in the problem is;
R is the resistance = 50.-ohm
v is the voltage = 120-volt source
I is the value of the current =0.50 ampere.
A) The equivalent resistance of the circuit shown will be 240 Ω.
According to ohm's law
[tex]\rm R= \frac{V}{I} \\\\ \rm R= \frac{120}{0.5} \\\\ \rm R=240 \ ohm[/tex]
Hence the equivalent resistance of the circuit shown will be 240 Ω.
B) The resistance of resistor R will be 190 Ω
The given resistors are connected in the series;
R = R1 + R2 +..... Rn
240 = 50 + R
R = 240 - 50
R = 190 Ω
Hence the resistance of resistor R will be 190 Ω
