Write the function y(x, t) that describes this pulse if it is traveling in the positive x-direction with a speed of 2.10 m/s. (U
Marrrta [24]

Answer:

The function is missing in the question. The function of the transverse pulse in the wire is given by $y=\frac{6}{x^2 +3}$  

Explanation:

A transverse wave can be defined as the wave whose direction of displacement is always perpendicular to the direction of propagation. For example, surface wave at water bodies. While a pulse can be defined as a sudden change in a constant quantity such as a pulse of the radiation or current.

Let the wire of infinite length in both the directions and also the magnitude of deflection of wire be in the same shape except the point of maximum deflection to move along the wire.

Thus the equation of the pulse moving the in the positive x-direction moving at the speed of 2.10 m/s is

$y=\frac{6}{(x-2.10)^2 +3}$.

How is luminosity affected by other characteristics of a star
Nitella [24]

Answer:As the size of a star increases, luminosity increases. If you think about it, a larger star has more surface area. That increased surface area allows more light and energy to be given off. Temperature also affects a star's luminosity.

Buster Posey hits a pop-up straight up. The velocity of the baseball as it leaves the bat is 42.5 m/s. Determine (a) the total t
SSSSS [86.1K]

Answer:

part a: 4.25s

part b: 180.625m

Explanation:

part a:

what we know: vi=42.5m/s

                          t=?

                          vf=0

                          g= -10m/s^2

----------------------------------------------------------

equation: vf-vi/g=t

plug in: -42.5m/s/ - 10m/s^2 = 4.25s

-----------------------------------------------------------

part b: 42.5m/s x(times) 4.25s = 180.625m
