Based on the direction of propagation compared to direction of vibration, waves are classified into:
1- Transverse waves: The direction of propagation of the wave is perpendicular to the direction of vibration of the medium particles.
2- Longitudinal waves: The direction of propagation of the wave is the same as the direction of vibration of the medium particles.
For the question we have here, since the direction of the wave is the same as the direction of vibration of particles, therefore, this wave is a longitudinal wave
Answer:
-5.1 kg m/s
Explanation:
Impulse is the change in momentum.
Change in momentum= final momentum - initial momentum=m
+m![v_{1}](https://tex.z-dn.net/?f=v_%7B1%7D)
Plugging in the values= -0.15*24 - (0.15*10) (The motion towards the pitcher is negative as the initial motion is considered to be positive)
Impulse=-5.1 kg m/s (-ve means that it is the impulse towards the pitcher)
Answer:
Rainbow or all the colors
Explanation:
Yes because something that has been electrically charged can make other things move without touching them ( this is called force without contact)
Hoped this helped :)
Answer:
(-y)-direction.
Explanation:
The force created by the magnetic field on a moving object is
![\vec{F}_B = q\vec{v} \times \vec{B}](https://tex.z-dn.net/?f=%5Cvec%7BF%7D_B%20%3D%20q%5Cvec%7Bv%7D%20%5Ctimes%20%5Cvec%7BB%7D)
So the directions are
![\vec{F}_B = \^x \times \^z = -\^y](https://tex.z-dn.net/?f=%5Cvec%7BF%7D_B%20%3D%20%5C%5Ex%20%5Ctimes%20%5C%5Ez%20%3D%20-%5C%5Ey)
The direction can also be found by the right-hand rule.
Point your index finger in the direction of velocity. Point your middle finger in the direction of magnetic field. Your thumb will point towards the direction of the force.
