Answer:The direction the wave travels is parallel to the displacement of the medium.LW.
Electromagnetic waves are an example of this type of wave. TW
Sound waves are an example of this type of wave.LW
Ir the wave propagates in the x‑direction, the medium is also disturbed in the x‑direction. LW
If the wave propagates in the x‑direction, the medium is disturbed in the y‑ and/or z‑direction. TW
The direction the wave travels is perpendicular to the displacement of the medium.TW
Explanación:
the main difference of Transversal AND Longitudinal waves (TW AND LW) is that the disturbation direction in the media with respect to the travel direction is well different for both cases. For TW the perturbation oscilatiew perpendicular to propagation direction of the wave.
In constrant for LW the disturbation oscilates in the same direction as the wave is propagating.

Answer:
<h2>The coefficient of static friction will be
0.7</h2>
Explanation:
Given data
the radius of curve= 90m
speed v= 90 km/h to m/s = (90*100)/60*60= 25 m/s
we know that the expression for the centripetal force acting on the car
-------1
we also know that the expression for the frictional force between road and tire.
Ff= μmg--------2
Equating equation 1 and 2 we have
μmg= mv^2/r
μ= v^2/gr
substituting the values of speed and radius we have (assuming g= 9.81m/s^2)
μ= 25^2/9.81*90
μ= 625/882.9
μ= 0.7
Answer:
2.) Use a wrench with a longer handle.
Explanation:
It is suggested to use a wrench with longer handle if you cannot exert enough force to loosen a bolt with a wrench.
In doing this work, the torque which is the force that can turn the screw is not enough;
Torque = force x distance
If we increase the distance or the length of the handle, we can generate more torque to overcome the force needed.
