Answer:
Initial position of a body is the position of the body before accelerating or increasing its velocity the position changes and then that position is the final position.

Question: A charge of 0.50 C moves horizontally in a magnetic field of 1.0 T with a speed of 4.0 x 10^⁻1 m/s. The force experienced by the charge is 7.0 N. What is the angle between the charge direction and the magnetic field?
Answer:
Θ = 6.56°
Explanation:
From the question,
Using
F = BvqsinΘ................... Equation 1
Where F = force experienced by the charge, B = magnetic field, q = Charge, Θ = angle between the charge abd the magnetic field, v = velocity.
Make Θ the subject of the equation
Θ =sin⁻¹ (Bvq/F)............... Equation 2
Given: v = 4.0×10⁻¹ m/s, B = 1.0 T, q = 0.50 C, F = 7.0 N
Θ = sin⁻¹(1×0.5×4×10⁻¹/7)
Θ = sin⁻¹(0.114)
Θ = 6.56°
Answer:
3260.33 J
Explanation:
= number of rods = 5
= length of each rod = 0.715 m
= mass of rod = 2.51 kg
= total moment of inertia
Total moment of inertia is given as
![I = \frac{nmL^{2}}{3}](https://tex.z-dn.net/?f=I%20%3D%20%5Cfrac%7BnmL%5E%7B2%7D%7D%7B3%7D)
![I = \frac{(5)(2.51)(0.715)^{2}}{3}](https://tex.z-dn.net/?f=I%20%3D%20%5Cfrac%7B%285%29%282.51%29%280.715%29%5E%7B2%7D%7D%7B3%7D)
= 2.14 kgm²
= angular speed = 527 rpm = 55.2 rad/s
Rotational kinetic energy is given as
E = (0.5)
(
)²
E = (0.5) (2.14) (55.2)²
E = 3260.33 J
The reciprocal of resistance or measure of a devices ability to conduct is called Conductance. Conductance is the ability of material that allows electricity to pass through it. The unit of conductance is seimens. It can also be represented by "mho" , inverse of "ohm" which is unit of resistance. Best example of conductive metals are silver and copper. Materials that allows conductivity are called Conductor. Material that partially allows conductivity are called Semi-conductor. Material that does not allow conductivity are called Insulator.
Conductance can also be defined as ability to flow. The term conductance is not only used for electrical conductivity, but it is also used for thermal conductivity and fluid conductivity.
Copper(I) chloride, commonly called cuprous chloride, is the lower chloride of copper, with the formula CuCl.
