<em>If the distance between the two objects is the same, then;</em>
Both the magnet and the coil moving toward each other at 10 cm/s each
A reversed polarity magnet moving away from the coil at 20 cm/s
<u>Calculate current that produces a magnetic field, and use the right hand rule 2, to determine the direction of current or the direction of magnetic field loops. </u>
Answer:
The weight of the person has a smaller magnitude.
Explanation:
For an observer in inertial frame of reference for the person in the elevator Newton's Second Law can be written as
Normal reaction acts upwards
Weight acts downwards
Here
N is the normal reaction force
mg is the weight of the person
g is acceleration due to gravity
U need to write better u egg head kid or tell your mom
Answer:
θ₂ = 90° - θ₁
Explanation:
When the light falls on a mirror it bounces back. This is know as reflection. The incident angle is equal to the angle of reflection.
Here, the light strikes the mirror at an angle = θ₁
To find the angle of reflection we first need to understand angle of incidence. The angle of incidence is the angle made between the incident ray and normal. Normal is an imaginary line drawn perpendicular line on the boundary of the mirror.
Since the light strikes the mirror at angle of θ₁, which is the angle between light ray and the mirror.
Angle of incidence = 90° - θ₁.
Thus, angle of reflection, θ₂ = 90° - θ₁
Answer:
Mass will be 4.437 kg
Explanation:
We have given force constant k = 7 N/m
Time period of oscillation T = 5 sec
So angular frequency 
We know that angular frequency is given by
Squaring both side
m = 4.437 kg
