The spider will cross the driveway <u>25.71 in seconds</u>.
Why?
It's a conversion problem, so, in order to solve it, we need to convert the units of the given information.
Let's convert the given speed (in cm/s) to m/s.
We know that:
So, converting we have:
Then, calculating the time, we have:
We have that the spider will cross the driveway in 25.71 seconds.
Have a nice day!
Answer:
The answer is B.
Barnard’s star, Sun, Altair, Achernar
Explanation:
Remember the brighter the star the higher the temperature, Red being the oldest of the stars orange middle age, white stars ( getting to its ends can be also a dwarf star), and blue star being the youngest of the stars Also blue is the hottest star
The figure (examples ) of the question is attached below.
Answer: The answer is prism.
Explanation:
When a ray of white light passes through the prism it separates into many colors or different wavelength of light is seen.
This phenomenon is known as diffraction .In the visible wavelengths of the electromagnetic spectrum, red, is diffracted most and violet is diffracted lowest due to shortest wavelength.
It appears like a rainbow of 7 colors because it is white light that diffracts into 7 colors after passing a prism.
I don't think that 4m has anything to do with the problem.
anyway. here.
A___________________B_______C
where A is the point that the train was released.
B is where the wheel started to stick
C is where it stopped
From A to B, v=2.5m/s, it takes 2s to go A to B so t=2
AB= v*t = 2.5 * 2 = 5m
The train comes to a stop 7.7 m from the point at which it was released so AC=7.7m
then BC= AC-AB = 7.7-5 = 2.7m
now consider BC
v^2=u^2+2as
where u is initial speed, in this case is 2.5m/s
v is final speed, train stop at C so final speed=0, so v=0
a is acceleration
s is displacement, which is BC=2.7m
substitute all the number into equation, we have
0^2 = 2.5^2 + 2*a*2.7
0 = 6.25 + 5.4a
a = -6.25/5.4 = -1.157
so acceleration is -1.157m/(s^2)

The application of a sufficiently strong magnetic field to a
superconductor will, in general, destroy the superconducting state. Two
mechanisms are responsible for this. The first is the Zeeman effect1, 2,
which breaks apart the paired electrons if they are in a spin-singlet
(but not a spin-triplet) state. The second is the so-called ‘orbital’
effect, whereby the vortices penetrate into the superconductors and the
energy gain due to the formation of the paired electrons is lost3. For the case of layered, two-dimensional superconductors, such as the high-Tc copper oxides, the orbital effect is reduced when the applied magnetic field is parallel to the conducting layers4.
Here we report resistance and magnetic-torque experiments on single
crystals of the quasi-two-dimensional organic conductor λ-(BETS)2FeCl4, where BETS is.
