There are many more things that cause temperature fluctuation around the average without causing the long-term average itself to change. This change is attributed by natural processes such as volcanic activity, solar variability, plate tectonics, or shifts in the Earth's orbit.

What are 5 violations of the rules for Ultimate Frisbee
Answer:
Violations. A violation occurs when a player violates the rules in a manner which does not result in physical contact ( e.g. throwing a pass during an approach to the goal line; illegal guarding position by the marker; not establishing a pivot foot after carrying the disc in from out-of-bounds, etc.)
The object of Ultimate Frisbee is to gain points by scoring goals. The disc may only be passed, and a goal is scored when a player successfully passes the disc to a teammate in the end zone which that team is attacking. The team with the most points at the end of the game is declared the winner.
Explanation:
Vert (Vertical) Stack – The most common offensive play in Ultimate Frisbee. The Mailman – An intense offensive tactical maneuver to guarantee a gain of at least 70% of the field. TurboDisc – Can be added to almost any play to ensure max effectiveness.
If contact occurs and the thrower drops the disc, the count stops until the thrower picks up the disc and continues with play. The defensive player will have to back up 5 yards (15 feet) to allow a free throw from the offensive player.

How many complete wavelengths are shown in this image? Do not count any partial wavelengths.
7
4
1
3
Answer:3
Explanation: I just took the quiz
The distance between two successive troughs or crests is known as the wavelength There are 3 complete wavelengths are shown in this image.
What is wavelength?The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.
The length of a wave is measured in its propagation direction. The wavelength is measured in meters, centimeters, nanometres, and other units since it is a distance measurement.
Hence Option D is correct. There are 3 complete wavelengths are shown in this image.
To learn more about the wavelength refer to the link;

to start something moving, a push force must be ______ than resisting forces such a friction. what word complets the gap?
Answer:
To start something moving, a push force must be greater than resisting forces such a friction.
Explanation:
The force of resistance, for example friction, slows things down, so the push force must be greater in order to increase the speed or to start something moving.
You arrive in my class 45 seconds after leaving math which is 90 meters away. How fast did you travel?
pls show equation
Answer:
1/2 seconds per meter
Explanation:
The number of seconds is going to be x
45 ÷ 90 = x
x = 1/2
I mean there are more complicated ways to do it, but this is the easy one :)
Answer:
1/2 per meter
Explanation:
3. Is the relationship between the gravitational force and the mass directly proportional or
inversely proportional?
Answer:
Directly Proportional
Explanation:
Gravitational force can be calculated with the equation F = g(m1 * m2)/ r^2
So if we increase mass, force will also increase because mass is in the numerator.
A 350kg motorcycle is moving at 20m/s. It then speeds up to 30m/s. How much work did the engine do to accelerate?

If a player through a basketball to the target with an initial velocity of 17 m/s making an angle of 30 degrees with the horizontal, calculate the final position made with the vertical (Yf) after 1.3 seconds.
Answer:
The final position made with the vertical is 2.77 m.
Explanation:
Given;
initial velocity of the ball, V = 17 m/s
angle of projection, θ = 30⁰
time of motion, t = 1.3 s
The vertical component of the velocity is calculated as;
[tex]V_y = Vsin \theta\\\\V_y = 17 \times sin(30)\\\\V_y = 8.5 \ m/s[/tex]
The final position made with the vertical (Yf) after 1.3 seconds is calculated as;
[tex]Y_f = V_yt - \frac{1}{2}g t^2\\\\Y_f = (8.5 \times 1.3 ) - (\frac{1}{2} \times 9.8 \times 1.3^2)\\\\Y_f = 11.05 \ - \ 8.281\\\\Y_f = 2.77 \ m[/tex]
Therefore, the final position made with the vertical is 2.77 m.
What is the Eg, Ek, and Ediss of a skier starting at an elevation of 40m and ending at 0m elevation
Answer:
E_g = m 392 J, Ek = m 392
Explanation:
Mechanical energy is a very important concept since if the system does not have friction it remains constant
the potential energy of a system is
E_g = U = m g (y2 - i)
E_g = m 9.8 (40 -0)
E_g = m 392 J
The kinetic energy for this system assuming it started from rest
E_k = K = ½ m v2
how mechanical energy is conserved
E_g = E_k
Ek = m 392

Using your knowledge of fluid pressure, explain why your ears hurt more and more as you dive deeper and deeper underwater.
Answer:
Ear pain is the most common complaint from scuba divers. Some divers call it "ear squeeze." As a diver goes deeper under water and the outer environment pressure increases, the pressure in the middle ear (the part behind the ear drum) is "squeezed" by the increasing pressure of the water from outside
