I dont think hurricanes have any fronts
Explanation:
A hurricane usually contains an eye with sinking air, whereas mid-latitude cyclones have a center of low pressure with rising air. Hurricanes have their strongest winds around the eye of the hurricane where mid-latitude cyclones have their strongest winds aloft, in the jet stream.
If an apple experiences a constant net force, it will have a constant
Answer:
As Force = Mass × Acceleration. So If mass is constant, the acceleration would also be constant, in presence of a net external constant force!
(PLEASE) You go sledding down a hill and are traveling toward the east. At 0s, your velocity is 0m/s. At 5s, your velocity is 30m/s. Calculate your acceleration.
Answer:
your acceleration is 6 m/s²
Explanation:
Given;
initial velocity, u = 0
initial time, t₀ = 0
final velocity, v = 30 m/s
final time, t = 5 s
The acceleration of is calculated as follows;
[tex]a = \frac{v-u}{t_1-t_0} \\\\a = \frac{30-0}{5-0} \\\\a =\frac{30}{5} \\\\a = 6 \ m/s^2[/tex]

Suppose that the separation between two speakers A and B is 4.80 m and the speakers are vibrating in-phase. They are playing identical 134-Hz tones and the speed of sound is 343 m/s. An observer is seated at a position directly facing speaker B in such a way that his line of sight extending to B is perpendicular to the imaginary line between A and B. What is the largest possible distance between speaker B and the observer, such that he observes destructive interference
Answer:
[tex]X=8.44m[/tex]
Explanation:
From the question we are told that
Distance b/w A&B [tex]x=4.80m[/tex]
Frequency [tex]f=134Hz[/tex]
Sound speed [tex]v=343m/s[/tex]
Generally the equation for wavelength is mathematically given as
[tex]\lambda=v/f[/tex]
[tex]\lambda/2=1/2*v/f[/tex]
[tex]\lambda/2=1/2*\frac{343}{135}[/tex]
[tex]\lambda/2=1.27037037[/tex]
Generally the destructive interference X is mathematically given by
[tex]\sqrt{4.8^2 +X^2} -X=1.27037037\\[/tex]
[tex]23.04+BC^2=X^2+1.613+2.54*X[/tex]
Therefore the destructive interference is
[tex]X=8.44m[/tex]
How often do very active sunspot and solar flare cycles take place?
Answer:
Every 11 years The solar cycle is the cycle that the Sun's magnetic field goes through approximately every 11 years.
Explanation:
Our Sun is a Large ball of electrically-charged hot gas. This charged gas moves, generating a powerful magnetic field. The Sun's magnetic field goes through a cycle, called the solar cycle.
Every 11 years or so, the Sun's magnetic field completely flips. This means that the Sun's north and south poles switch places. Then it takes about another 11 years for the Sun’s north and south poles to flip back again.
The solar cycle affects activity on the surface of the Sun, such as sunspots which are caused by the Sun's magnetic fields. As the magnetic fields change, so does the amount of activity on the Sun's surface.
Hope this helps!

Newton's 3rd Law is based on what type of forces?
Answer: His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A.
Explanation:
Explanation:
According to Newton's third law of motion, whenever two objects interact, they exert equal and opposite forces on each other. This is often worded as 'every action has an equal and opposite reaction'.

During parkour, a person leaps at a wall and performs a flip. What must they do to change
directions?
6
Answer:
they push off the wall with a force greater than the wall
Explanation:
The game of parkour involves moving from one point to another and performing several skills which includes flips, especially in a difficult environment.
To change directions, the person must exert a significant force on the wall.
When the person leaps on the wall, it means the person moves or jumps quickly on the wall.
While this is being carried out, the concept of force must be applied.
If the force that acts on a stationary object is smaller than the required force to move the object, the object's position remains unchanged.
This means that for the person's direction to change, the person must exact a great force (or a significant force) enough to cause a change in direction.

An electron is released from rest at the negative plate of a parallel plate capacitor and accelerates to the positive plate (see the drawing). The plates are separated by a distance of 1.0 cm, and the electric field within the capacitor has a magnitude of 2.9 x 106 V/m. What is the kinetic energy of the electron just as it reaches the positive plate
Answer:
K = 4.64 10⁻¹⁵ J
Explanation:
For this exercise we can use conservation of energy
starting point. Next to the negative plate
Em₀ = U = e V
final point. Right when you hit the positive plate
Emf = K = ½ m v²
energy is conserved
Em₀ = Em_f
e V = K
The electric potential is related to the electric field
V = - Ed
we substitute
-e E d = K
let's calculate
K = -1.6 10⁻¹⁹ (-2.9 10⁶) 1.0 10⁻²
K = 4.64 10⁻¹⁵ J

Explanation:
You are hiking pine mountain and have finally reached the top. You are peering over the edge and accidentally drop your phone while taking pictures. Your phone falls and hit the
ground 13 seconds later. How tall is the mountain?
Answer:
The cliff is 12.71m tall.
Explanation:
Why?
Before solving the problem, we must remember that the phone was dropped, it means that there is no initial velocity, also, the acceleration acting on the phone is the acceleration due to gravity.
So, to find how tall is the cliff, we can use the following equations:
\begin{gathered}y=y_o+v_o*t-\frac{1}{2}g*t^{2}\\\\v_f=v_o+g*t\end{gathered}y=yo+vo∗t−21g∗t2vf=vo+g∗t
\begin{gathered}t=\frac{v_f}{g} \\\\t=\frac{-15.75\frac{m}{s}}{-9.81\frac{m}{s^{2}}}=1.61s\end{gathered}t=gvft=−9.81s2m−15.75sm=1.61s
Now that we know the time, we can calculate how tall is the cliff:
\begin{gathered}y=y_o+v_o*t+\frac{1}{2}g*t^{2}\\\\y=0+0*1.61s-\frac{1}{2}*(-9.81\frac{m}{s^{2}})*(1.61s)^{2}\\\\y=12.71m\end{gathered}y=yo+vo∗t+21g∗t2y=0+0∗1.61s−21∗(−9.81s2m)∗(1.61s)2y=12.71m

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 20 cm in diameter, separated by 1.0 cm. How much charge can be added to each of the plates before a spark jumps between the two plates? For such flat electrodes, the field that causes a spark is at the high end of the range pre- sented in the chapter; assume a value of 3 * 106 N/C.
Answer:
Q = 0.83 μC
Explanation:
Assuming that plates are much larger than the distance between them, we can think the electric field as constant and perpendicular to the outer surface of the plates.Applying Gauss' law to a rectangular surface half inside one of the plates and half outside it, since E and A are parallel each other, and E is zero on the other three faces, we can find the following expression for the electric field created by the charge on the plate:[tex]E = \frac{Q*A}{\epsilon_{0} } (1)[/tex]
Solving for Q, replacing E by the maximum electric field that doesn't cause the dielectric strength to break (3*10⁶ N/C), we get:[tex]Q_{max} = E_{max} * \pi *\frac{d^{2}}{4} *\epsilon_{0} = 3e6N/C*\pi *\frac{(0.2m)^{2} }{4} * 8.85e-12C2/Nm2 = 0.83\mu C (2)[/tex]

The height of the observation deck of the Empire State Building is 380 m. If you dropped a penny from this height, how fast would it be going when it struck the ground? Assume there is no air resistance.
Given :
The height of the observation deck of the Empire State Building is 380 m.
A penny is dropped from this height.
To Find :
How fast would it be going when it struck the ground.
Solution :
Initial speed, u = 0 m/s.
We know, speed of object free falling is given by :
[tex]v^2 - u^2 = 2gh\\\\v = \sqrt{2gh}[/tex]
Here, g = 9.8 m/s² = acceleration due to gravity.
Putting all values in above equation, we get :
[tex]v = \sqrt{2\times 9.8\times 380}\ m/s\\\\v = 86.30\ m/s[/tex]
Hence, this is the required solution.
