Answer:
The speed is the same as long as the reflection is regular.
Explanation:
This is because in regular reflection, the angle of incidence is equal to the angle of reflection in accordance with the second law of reflection.
Since speed of light depends on the angle of the light ray it makes with the reflecting surface, the speed is the same
Answer:
The magnitude of the magnetic force on the rod is 0.037 N.
Explanation:
The magnetic force is given by:
Since the charge (q) is:
Where<em> I</em> is the current = 1.40 A, and <em>t</em> the time
And the speed (v):
Where <em>L </em>is the tracks separation = 2.20 cm = 0.022 m
Hence, the magnetic force is:
Where <em>B </em>is the magnetic field = 1.20 T and <em>θ</em> is the angle between the tracks and the magnetic field = 90°
Therefore, the magnitude of the magnetic force on the rod is 0.037 N.
I hope it helps you!
Answer:
False.
Explanation:
A public health license can be defined as series of privileges and authority granted to a practitioner in the public domain, to offer services to the general public after admitting to comply with the standards, rules and regulations set aside by health regulatory agencies and the government (both state and federal).
This ultimately implies that, all restaurant owners must have met the minimum requirements (criteria) and agree to comply with all the standards, rules and regulations with respect to public health before they are endorsed and then given a license to practice or operate by the appropriate agency or authorities.
Hence, restaurant owners agree to comply with state, federal, and health regulations when applying for a public health license.
