What is the main difference between a longitudinal wave and a transverse wave? a longitudinal wave always travels faster than a transverse wave. a longitudinal wave does not need a medium to travel through. a transverse wave is made of particles that move perpendicular to the motion of the wave. a transverse wave always carries more energy so that it can travel through empty space.

Answers

In a longitudinal wave, the propagation of energy is in the direction of the motion, while in a transverse wave the propagation of energy is perpendicular to the direction of motion.

What is longitudinal wave and Transverse wave?

Longitudinal wave is a wave which moves in the direction from where it was started. It has a compression (increased intensity) of the medium particles and a rarefaction ( reduced intensity).

Transverse wave is wave that travels perpendicular or at right angles to the direction from where it was started.

The main differences between longitudinal wave and Transverse wave are:

Transverse wave, the medium moves vertically up and down while in the longitudinal wave, the medium moves left to right.Transverse wave has a crest and a trough while the longitudinal waves have a compression and rarefaction.Transverse waves don't have a pressure variation , longitudinal waves have a pressure variation.Transverse waves can only be propagated in solids and on the surfaces of liquids, Longitudinal waves can be propagated in solids, liquids and gases.Transverse waves don't change in density throughout the medium, longitudinal waves have a change in density throughout the medium.

Therefore,

The propagation of energy is in the direction of the motion, while in a transverse wave the propagation of energy is perpendicular to the direction of motion.

When the spheres are moved apart again, each one is left with half of the total original charge…

A car initially traveling at 15.0 m/s accelerates at a constant rate of 4.50 m/s2 over a distance of 45.0 m. How long does it take the car to cover this distance? Show all work leading to the answer including the data, equation, substitution and the final answer with units for full credit.

Answers

Answer:

2.24 seconds

Explanation:

xf = xo + vo t + 1/2 at^2

45 = 0 + 15 t  + 1/2 (4.5) t^2

   2.25 t^2 + 15t - 45 = 0              Quadratic formula shows  t = 2.24 seconds

The car takes approximately 2.25 seconds to cover a distance of 45.0 meters under the given conditions of constant acceleration.

Given data:

Initial velocity (u) = 15.0 m/s

Acceleration (a) = 4.50 m/s²

Distance (s) = 45.0 m

We can use the kinematic equation to solve for time (t) when the car covers a certain distance under constant acceleration:

S = ut + 1/2at²

Where:

s = distance

u = initial velocity

a = acceleration

t = time

Plugging in the given values:

45.0 = 15.0t + 1/2 m/s²t²

2.25t² +15t - 45 = 0

t = 2.25sec and -8.92sec

Since time cannot be negative in this context, we discard the negative solution.
