What is the name of the temperature zone that includes the equator? How many degrees of latitude does this zone cover zone? I have to get it done right now
Answers
The name of the temperature zone that includes the equator is Zone C and is referred to as the tropical zone.
What is Tropical zone?This is referred to as the type of zone which is characterized by areas or regions around the equator. The name tropical was coined from its distinct climate which is usually warm all year round as a result of its very high sun exposure.
The degrees of latitude which this zone covers is 23.5 degrees and is south of the Equator which is therefore the reason why it was chosen as the most appropriate choice.

A car is traveling at vx= 20 m/s . the driver apples brakes and the car slows down at ax=-4.0 m/s^2 what is the stopping distance?
Answers
The stopping distance for a car traveling at a velocity of 20 m/s and acceleration of -4 m/s^2 is 50 m.
The above situation is a case of motion in one dimension, which is governed by the following equations,
V = u + at ..........(i)
V^2 - u^2 = 2as ..........(ii)
S = ut + 1/2 at^2 .........(iii)
As we are given the initial velocity, the final velocity, and the acceleration, therefore we have to apply the second equation to get the answer
v^2 - u^2 = 2as
Here v is the final velocity = 0 m/s
u is the initial velocity = 20 m/s
a is the acceleration = -4 m/s^2
And s is the distance traveled by car
Putting the given values in the above equation,
(0) ^2 - (20)^2 = 2(-4)s
-400 = -8s
S = 50 m
Hence, The stopping distance for a car traveling at a velocity of 20 m/s and acceleration of -4 m/s^2 is 50 m.

Answers
The average acceleration of the ball, while it is in contact with the wall, is -3969.27 m/s².
Acceleration is the rate of change of velocity per unit of time. Its S.I. unit is m/s². It is equal to the change in velocity divided by the time taken to change the velocity.
Acceleration a = Change in velocity/ Time taken
Given in the question
Initial Velocity = u = + 20.6 m/s ( towards the wall is positive direction )
Final Velocity = v = - 11.948 m/s (away from the wall is negative direction)
Change in Velocity = Final Velocity - Initial Velocity
= (- 11.948) - ( + 20.6)
= -11.948 - 20.6
= -32.548 m/s
So Change in velocity = 32.548 m/s
Time Taken = Time of contact with the wall
= 0.0082 seconds
Put in the Formula: a = Change in velocity/ Time taken
a = -32.548/0.0082
a = -3969.27 m/s²
Therefore the average acceleration of the ball, while it is in contact with the wall, is -3969.27 m/s².

When earth catches up to a slower-moving outer planet and passes it in its orbit, in the same way that a faster runner overtakes a slower runner in an outside lane, the outer planet.
Answers
When earth catches up to a slower-moving outer planet and passes it in its orbit, in the same way that a faster runner overtakes a slower runner in an outside lane, the outer planet exhibits retrograde motion.
What do you mean by retrograde motion?
Retrograde motion, in astronomy, the actual or apparent motion of a body in the opposite direction to the direction of the (direct) motions of most members of the solar system or other astronomical systems with a preferred direction of motion. Viewed from a position in space north of the Solar System (from some great distance above Earth's north pole), all the major planets revolve around the Sun in a counterclockwise direction, and all but Venus and Uranus rotate counterclockwise about their own axes; these two, therefore, have retrograde rotation. Of the known satellites of the planets, a minority show retrograde revolution. These include the four outermost moons of Jupiter; Phoebe, Saturn's outermost moon; and Triton, the largest of Neptune's moons. The orbital planes of the satellites of Uranus are so strongly inclined that describing the motion of these bodies as retrograde or direct has little meaning. The rotations around the Sun of all known asteroids are direct; of the known periodic comets, only a few, one of which is Halley's Comet, move in a retrograde orbit.To learn more about retrograde motion, refer to:

Is it correct to say that, if no net impulse is exerted on a system, then no change in the momentum of the system will occur?.
Answers
Yes, it is correct to say that if no net impulse is exerted on a system, then no change in the momentum of the system will occur.
Impulse is defined as the instantaneous force applied to the object for a very short duration. It is given by the product of force and time. The expression of the impulse is given by
I = F × t where ,
F is the force
t is the time
The impulse is also defined as the change in the momentum of the object, that is,
[tex]I=Pf-Pi[/tex] where [tex]Pf[/tex] is the final momentum of the object [tex]Pi[/tex] is the initial momentum of the object
Hence, if the net impulse is zero, therefore
0=[tex]Pf[/tex]=[tex]Pi[/tex]
[tex]Pf[/tex]=[tex]Pi[/tex]
hence the momentum of the object will also not change.

When the magnitude remains came and the direction changes the particle is moving in a circular motion. Speed is equal to the arc length traveled (S) divided by the change in time (Δ),
A particle travels in a uniform circular motion while maintaining a constant speed. The radius R of the circle sweeps out the angle, and the particle's velocity vector v in the illustration has a constant magnitude but changes direction as it advances from location B to position C.
The isosceles triangles OBC and DEF are identical because OB and OC are perpendicular to the velocity vectors, and as a result, the ratio of the chord BC to the radius R is the same as the ratio of the magnitudes of v to v. The chord BC and the arc BC approach one another as approaches zero, and the chord can be replaced by the arc in the ratio.

When burned with just the stoichiometric amount of air, under conditions where no heat is lost, the temperature range in which it will produce flames is around 2100 K to 2300 K.
Stoichiometric combustion, in which all available oxygen is fully used, is burning without excess or lack of air. The general equation of a stoichiometric combustion can be determined by presuming that nitrogen reacts in extremely small amounts and is discovered after combustion in molecule form.
Stoichiometric or theoretical air is the smallest amount of air required for a fuel to burn completely. Stoichiometric combustion theoretically gives the ideal fuel to air ratio, which reduces losses and gets all of the energy from the fuel; but, in practice, stoichiometric combustion is not possible due to a variety of different variables.

Part a.
If F = 6°C, then
6°C = 1.8°C + 32
6°C - 1.8°C = 32
4.2°C = 32

S = (v+u)t/2.......... Equation 1Where:
S = Distancev = Final velocityu = Initial velocityt = TimeFrom the question,
Given:
v = 50 m/su = 11 m/st = 3.33×10⁻³ sSubstitute these values into equation 1
S = (50+11)3.33×10⁻³ /2S = 0.203 mHence, the distance traveled by the puck is 0.203 m.

A 12-n force is applied at the point x=3m, y=1m. find the torque about the origin if the force points in (a) the x direction, (b) the y direction, and (c) the z direction.
Answers
The torque about the origin if the force points in (a) the x direction, (b) the y direction, and (c) the z direction are 12; 36; 37.9 respectively
Torque is a twisting force produced by applying a force at a distance from a point. We would need to choose a distance that is perpendicular to the force's direction. We apply the equation to determine torque,
T=Fd
where F is the force and d is the orthogonal distance to a central point.
i. If the force points in the x-direction, we need to use the y-distance to calculate torque.
T=Fxdy
T=12N *1m
T = 12 N.m
ii. If the force points in the y-direction, we need to use the x-distance to calculate torque.
T=Fxdy
T= 12N * 3m
T = 36 N.m
iii. If the force is directed in the z-direction, the straight-line distance from the origin to the point is orthogonal to the force. The magnitude of the distance will be used as the distance value. This may be determined using the equation.
||d||= √ (X2 + Y2)
where X and Y are the x and y coordinates.
T=Fz||d||
T=(12N) (√ (32 + 12)
T = 37.9 N.m
