Answer:
Then its acceleration is zero.
Explanation:
Velocity → Uniform → Constant
→ Change in Velocity = 0
A= = (v=m)
a=0
Answer:
Factors Affecting the Strength of the Magnetic Field of an Electromagnet: Factors that affect the strength of electromagnets are the nature of the core material, strength of the current passing through the core, the number of turns of wire on the core and the shape and size of the core
Explanation:
Answer:
The peak current carried by the axon is 5.85 x 10⁻⁸ A
Explanation:
Given;
distance of the field from the axon, r = 1.3 mm
peak magnetic field strength, B = 9 x 10⁻¹² T
To determine the peak current carried by the axon, apply the following equation;
where;
B is the peak magnetic field
r is the distance of the magnetic field from axon
μ is permeability of free space = 4π x 10⁻⁷
I is the peak current
Re-arrange the equation and solve for "I"
Therefore, the peak current carried by the axon is 5.85 x 10⁻⁸ A
Answer:
Explanation:
Given
velocity of antelope
antelope needs to cover a horizontal distance of 20 m
considering horizontal velocity antelope needs to cover 20 m in t sec which is given by
i.e. in 2 sec antelope needs to jump and return to ground for zero vertical displacement
h=vertical displacement
a=acceleration
t=time
for, , t=1 s
Answer:
Every electric circuit, regardless of where it is or how large or small it is, has four basic parts: an energy source (AC or DC), a conductor (wire), an electrical load (device), and at least one controller (switch). Visualize what happens when you switch on a room light.
