Answer:
The two planetary movements are revolution and rotation.
Explanation:
In the vast solar system, planets traverse while also remaining fixated within the system because of gravity. Each planet is unique and so is its movement, but, at the same time, there are two common types of movements.
Question:
A wire 2.80 m in length carries a current of 5.20 A in a region where a uniform magnetic field has a magnitude of 0.430 T. Calculate the magnitude of the magnetic force on the wire assuming the following angles between the magnetic field and the current.
(a)60 (b)90 (c)120
Answer:
(a)5.42 N (b)6.26 N (c)5.42 N
Explanation:
From the question
Length of wire (L) = 2.80 m
Current in wire (I) = 5.20 A
Magnetic field (B) = 0.430 T
Angle are different in each part.
The magnetic force is given by
So from data
Now sub parts
(a)
(b)
(c)
V1T1=V2T2. vi = 25L T1=273+20 V2=273+35
Answer:
when current passes through a wire amagnetic field is created.
