Answer:
Electronmagnetic waves: yes
Mechanical waves: no
Explanation:
Electromagnetic waves consist of electric fields and magnetic fields that oscillate perpendicularly to each other, and also in a plane perpendicular to the direction of propagation of the wave (therefore they are called "transverse waves".
As all waves, electromagnetic waves transport energy (but not matter). In particular, the type of energy transferred by electromagnetic waves is in the form of radiation, also called light energy.
Conversely, mechanical waves consist of oscillations of the particles in a medium. Mechanical waves also carries energy (but not matter), but not in the form of radiation (light energy): in fact, the energy is carried as vibrations of the particles in the medium, so it is a different type of energy.
Answer:
a.
b.
Explanation:
The inertia can be find using
a.
now to find the torsion constant can use knowing the period of the balance
b.
T=0.5 s
Solve to K'
Without friction, NO.
The speed at D depends only on the difference in height between A and D. Whatever happens between them doesn't matter.
Answer:
D. Current with not flow through a wire if the magnet is outside the coil.
Explanation:
have a good day
Given the time and the horizontal velocity, we can simply
compute for the distance how far the ball travelled using the formula:
distance = velocity * time
<span>Since velocity is in units of m/s and time is seconds,
therefore we can directly get a unit in meters.</span>
