How far could you speed walk in 10 minutes? Use your speed from the 20m test to calculate the answer.
my speed is 13.63.
Answer:
Explanation:
Given parameters:
Time for speed walking = 10min
Speed = 13.63?
Unknown:
Distance you can speed walk = ?
Solution:
To solve this problem, we simply apply the velocity - time equation;
Speed = [tex]\frac{distance}{time}[/tex]
Distance = speed x time
make sure you speed and time are in the same unit

A layer of water Δx m thick which lies x m above the bottom of the tank will be rectangular with length 8 m. Using similar triangles, we can see that it will have widt of_____m
Answer:
x
Explanation:
The question relates to the energy required to pump water out of the
spout at the top of the triangular prism tank.
The width of the layer of water Δx thick is x m.
Reasons:
The location of the layer Δx m thick = x meters above the bottom
The length of the triangular (cross-section) prism tank = 8 meters
The length of the layer Δx thick layer = 8 meters
From the attached drawing of the cross-section of the tank, we have;
The height of the triangular tank cross-section = 3 meters
The length of the base of the triangular cross-section = 3 meters
By similar triangles, we have;
[tex]\dfrac{Height \ of \ Tank}{Base \ length \ of \ tank}= \dfrac{Height \ of \ layer \ with \ thickness \ \Delta x }{Width \ of \ layer \ with \ thickness \ \Delta x}[/tex]
Which gives;
[tex]\dfrac{3}{3} =\dfrac{x}{Required \ width}[/tex]
[tex]\dfrac{3}{3} =1 = \dfrac{x}{Required \ width}[/tex]
Required width × 1 = x
The required width = x m

A particle with charge q on the negative x axis and a second particle with charge 2q on the positive x axis are each a distance d from the origin. Where should a third particle with charge 3q be placed so that the magnitude of the electric field at the origin is zero? (Use any variable or symbol stated above as necessary.)
Answer:
The charge 3q must be placed at a distance of 1.73d away from the origin.
Explanation:
The electric field at the origin due to q at distance, d from the origin is E = q/4πε₀d².
The electric field at the origin due to 2q at distance, d from the origin is E' = -2q/4πε₀d². (It is negative since it its directed towards the negative x-axis)
Now, the net electric field at the origin due to both charges is thus E" = E + E' = q/4πε₀d² + (-2q/4πε₀d²) = q/4πε₀d² - 2q/4πε₀d² = -q/4πε₀d².
The electric field due to 3q at a distance x from the origin is E₁ = 3q/4πε₀x².
Now, the net electric field E' must cancel out E₁ so that the electric field at the origin is zero.
So, E' + E₁ = 0
E' = -E₁
-q/4πε₀d² = -3q/4πε₀x²
1/d² = 3/x²
taking inverse of both sides, we have
x²/3 = d²
multiplying both sides by 3, we have
x² = 3d²
taking square root of both sides, we have
x = (√3)d
x = ±1.73d
So, the charge 3q must be placed at a distance of 1.73d away from the origin.

(b) The cabin and passengers have a total mass of 800 kg. The vertical distance between
B and C is 50 m.
Calculate the increase of gravitational potential energy of the cabin and passengers when they
move from B to C.
energy =
Answer:
392 kJ
Explanation:
Given that,
The total mass of the cabin and the passengers = 800 kg
The vertical distance between B and C is 50 m.
We need to find the increase of gravitational potential energy of the cabin and passengers when they move from B to C. It can be given by the relation as follows :
[tex]E=mgh\\\\E=800\times 9.8\times 50\\\\E=392000\ J\\\\\text{or}\\\\E=392\ kJ[/tex]
So, the increase in gravitational potential energy is 392 kJ.

gamma rays
ultraviolet light
Answer:
i believe it is the microwaves that is closest to the radio waves.
Explanation:
The microwaves are the part of the electromagnetic spectrum is nearest to radio waves.
What is meant by electromagnetic spectrum?The range of all EM radiation arranged from high to low frequency (short to long wavelength) according to their frequency or wavelength. is known as the electromagnetic spectrum (EM).
Here,
The visible light from a bulb in your home and the radio waves from a radio station are two examples of electromagnetic radiation. Radiation is energy that travels and disperses as it does.
The properties of the electromagnetic spectrum include the ways in which signals can propagate and how much data they can carry. Signals delivered at higher frequencies typically propagate more quickly but can carry more data in a given amount of space.
The electromagnetic spectrum begins with the lowest frequency radio waves and moves up in frequency and down in wavelength from there. Radio waves are followed by visible light, infrared radiation, and lastly microwaves.
Hence,
The microwaves are the part of the electromagnetic spectrum is nearest to radio waves.

A rescue pilot drops a survival kit while her plane is flying at an ultitude of 2500m with a forward velocity of 95m. If the air friction is disregarded, how far advance of the starving explorer’s drop zone should she release the package?
Answer:
Approximately [tex]2.1\; \rm km[/tex], assuming that [tex]g = -9.8\; \rm m \cdot s^{-2}[/tex].
Explanation:
Let [tex]t[/tex] denote the time required for the package to reach the ground. Let [tex]h(\text{initial})[/tex] and [tex]h(\text{final})[/tex] denote the initial and final height of this package.
[tex]\displaystyle h(\text{final}) = \frac{1}{2}\, g\, t^2 + h(\text{initial})[/tex].
For this package:
Initial height: [tex]h(\text{initial}) = 2500\; \rm m[/tex].Final height: [tex]h(\text{final}) = 0\; \rm m[/tex] (the package would be on the ground.)Solve for [tex]t[/tex], the time required for the package to reach the ground after being released.
[tex]\displaystyle t^{2} = \frac{2\, (h(\text{final}) - h(\text{initial}))}{g}[/tex].
[tex]\begin{aligned} t &= \sqrt{\frac{2\, (h(\text{final}) - h(\text{initial}))}{g} \\ &\approx \sqrt{\frac{2\times (0\; \rm m - 2500\; \rm m)}{(-9.8\; \rm m \cdot s^{-2})}} \approx 22.588\; \rm s\end{aligned}[/tex].
Assume that the air resistance on this package is negligible. The horizontal ("forward") velocity of this package would be constant (supposedly at [tex]95\; \rm m \cdot s^{-1}[/tex].) From calculations above, the package would travel forward at that speed for about [tex]22.588\; \rm s[/tex]. That corresponds to approximately:[tex]95\; \rm m \cdot s^{-1} \times 22.588\; \rm s \approx 2.1 \times 10^{3}\; \rm m = 2.1\; \rm km[/tex].
Hence, the package would land approximately [tex]2.1\; \rm km[/tex] in front of where the plane released the package.
