Answer:
0.61 second.
Explanation:
So, from the question we are given the following useful parameters or data or information that is going to assist us in solving this question and they are;
(1). Inclination of plane, θ = 50°.
(2). ''The horizontal and a cylindrical metal is allowed to roll between two fixed height 92cm apart on the plane" that is height = 0.92 m(92cm).
(3). The "acceleration of the cylinder to be 2/3 × g Sin (theta) and g = Acceleration due to gravity = 9.8m/s^2
Soz let us delve right into the solution to the question above. We will be making use of the mathematical representation or Equation below;
s = (1/2) a × t².
Where s = height, a = acceleration due to gravity and t = time.
0.92 = (9.8 × sin 50°/ 3) × t².
t² = 0.37
t = √ 0.37.
t =0.61 seconds.
Answer:
I = 21.94 A
Explanation:
Given that
B= 0.15 T
Number of turns N= 3100
Length L = 57 cm
Diameter ,d= 7 cm
We know that magnetic field in the solenoid given as
Now by putting the values
I = 21.94 A
Therefore current need to produce 0.15 T magnetic filed is 21.94 A.
Using q=1.60217662 E-19 C we get:
Then using 9.10938356E-31 kg as the mass, we get
The motion of particles to one side of the rest position will be the same as the motion of the other side of the rest position in a wave motion. because in a wave motion or wave function, it symmetrical. meaning the motion on the other side will be identical to the other side of the rest position
