What effect does the vertical acceleration have on the horizontal velocity of the projectile?

Physics
1 answer:
KengaRu [80]4 years ago
3 0
Answer:
None, if air resistance is ignored.

Explanation:
At any instant, the projectile has vertical and horizontal components of velocity.
Vertical acceleration due to gravity affects the vertical velocity by accelerating the object toward the center of the earth, and by decreasing the upward vertical velocity.. 
The horizontal component of velocity makes the object travel horizontally as long as the projectile is airborne.
Thsi discussion assumes that air resistance is ignored.

Consider a monochromatic electromagnetic plane wave propagating in the x direction. At a particular point in space, the magnitud
weqwewe [10]

Answer:

a)   S = 2.35 10³   J/m²2 ,  

b)and the tape recorder must be in the positive Z-axis direction.

the answer is 5

c) the direction of the positive x axis

Explanation:

a) The Poynting vector or intensity of an electromagnetic wave is

          S = 1 /μ₀ E x B

if we use that the fields are in phase

          B = E / c

we substitute

         S = E² /μ₀ c

let's calculate

        s = 941 2 / (4π 10⁻⁷  3 10⁸)

        S = 2.35 10³   J/m²2

 

b) the two fields are perpendicular to each other and in the direction of propagation of the radiation

In this case, the electro field is in the y direction and the wave propagates in the ax direction, so the magnetic cap must be in the y-axis direction, and the tape recorder must be in the positive Z-axis direction.

the answer is 5

C) The poynting electrode has the direction of the electric field, by which or which should be in the direction of the positive x axis

In air, the 57 GHz radio wave has a shorter<br> wavelength compared to the 64 GHz radio wave.
dalvyx [7]

Answer:

False

Explanation:

Higher frequency signals have shorter wavelengths. Hence, the 64 GHz signal will have a shorter wavelength than the 57 GHz signal.

Frequency and wavelength are inversely proportional meaning as frequency increases wavelength decreases and as frequency decreases wavelength increases.

Cheers.

Why might it be helpful to us to measure gravity fluctuations on Earth? What is the most important type of information it gives
Anna [14]
I think it would be helpful to measure gravity so we know how it affects animals and plants and planes and spaceships and cars. I think the most important type of information it gives us is just like making sure people are safe and that there’s nothing we are going on or that the gravity increases at a rate or if it decreases just so we know how to handle it in the future and I think that information would be useful so we don’t die.
