What latitudes experience both summer and winter?
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.

bucket.

Felix selects a golf ball at random. Based on the information in the table, which statement is
true?
A The golf ball is more likely to be green than all other colors combined.
B The golf ball is equally likely to be pink, white, orange, or green.
C The golf ball is 2 times as likely to be orange as it is to be pink.
D The golf ball is 7 times as likely to be green as it is to be white.
The golf ball is two times as likely to be orange as it is to be pink. Therefore, option C is correct.
What is probability?Probability can be described as the branch of mathematics of numerical descriptions of how likely an event is to take place. The probability of an event can be a number between 0 and 1, where 0 indicates the impossibility of the event and 1 shows certainty.
Given, the number of pink balls = 4
The number of white balls = 11
The number of orange balls = 8
The number of green balls = 18
The total number of balls = 4 + 11 + 8 + 18 = 41
When Felix picks a golf ball at random. The golf ball is more likely to be pink = 4/41
The probability golf ball is more likely to be white = 11/41
The probability golf ball is more likely to be orange = 8/41
The probability golf ball is more likely to be green = 18/41
Therefore, the golf ball is two times as likely to be orange as it is to be pink.

Which is greater 45 RPM or 4.71 rad/s? Why?
45 rpm is greater/faster. Convert both measurements to the same unit rate:
45 rpm = (45 rev) / (1 min) = (45 rev) / (60 s) = 0.75 rps
4.71 rad/s = (4.71 rad) / (1 s) • (1 rev) / (2π rad) = (4.71 rev) / (2π s) ≈ 0.74962 rps

If the frequency of a wave is 0.25 Hz, what is its period?
A) 0.25 s
B) 2 s
C) 4 s
D) 4 HZ
Answer:
C
Explanation:
frequency = 1 / period
so
frequency = 0.25
0.25 = 1 / period
1 / 0.25 = period
4 s = period
it is not 4 Hz because period is the time taken
so the answer is C

A piece of wire length 30cm and cross sectional area of 0.5mm^2 has a resistance of 5ohms at 20°c. It is then heated to a temperature of 150°c. Calculate it's resistivity at 20°c
Answer:
8.333*10^-6 ohms
Explanation:
Resistivity of a material is expressed as;
p = RA/l
R is the resistance of the material
A is the cross sectional area
l is the length of the material
Given
R = 5 ohms
A = 0.5mm^2
A = 5 * 10^-7m^2
l = 30cm = 0.3m
Substitute into the formula;
p = (5 * 5 * 10^-7m^2)/0.3
p = 25 * 10^-7/0.3
p = 0.0000025/0.3
p = 8.333*10^-6
Hence its resistivity at 20 degrees Celsius is 8.333*10^-6 ohms

1. A satellite (mass = 4.44 x 109 kg) travels in orbit around the Earth at a distance of 1.9 x 10'm above
Earth's surface. What is the force of gravitational attraction between the satellite and Earth?
Answer:
The force of gravitational attraction between the satellite and Earth is [tex]2.587\times 10^{10}[/tex] newtons.
Explanation:
Statement is incorrect. Correct statement is:
A satellite ([tex]m = 4.44\times 10^{9}\,kg[/tex]) travels in orbit around the Earth at a distance of [tex]1.9\times 10^{6}\,m[/tex] above Earth's surface. What is the force of gravitational attraction between the satellite and Earth?
The gravitational force experimented by the satellite ([tex]F[/tex]), in newtons, is calculated by Newton's Law of Gravitation, whose equation is defined by following formula:
[tex]F = \frac{G\cdot m \cdot M}{R^{2}}[/tex] (1)
Where:
[tex]G[/tex] - Gravitational constant, in cubic meters per kilogram-square second.
[tex]m[/tex] - Mass of the satellite, in kilograms.
[tex]M[/tex] - Mass of the Earth, in kilograms.
[tex]R[/tex] - Distance of the satellite with respect to the center of the Earth, measured in meters.
If we know that [tex]G = 6.674\times 10^{-11}\,\frac{m^{3}}{kg\cdot s^{2}}[/tex], [tex]m = 4.44\times 10^{9}\,kg[/tex], [tex]M = 5.972\times 10^{24}\,kg[/tex] and [tex]R = 8.271\times 10^{6}\,m[/tex], then the force of gravitational attraction between the satellite and Earth is:
[tex]F = 2.587\times 10^{10}\,N[/tex]
The force of gravitational attraction between the satellite and Earth is [tex]2.587\times 10^{10}[/tex] newtons.
