Answer:
yes independent of the sign or valve of Q
Explanation:
Answer:
The radius is 
Explanation:
From the question we are told that
The magnetic field is 
The electron kinetic energy is 
Generally for the collision to occur the centripetal force of the electron in it orbit is equal to the magnetic force applied
This is mathematically represented as
=> 
Where m is the mass of electron with values
v is the escape velocity which is mathematically represented as

So

apply indices

substituting values


Answer: most effective way is to practice reduce reuse and recycle for utilisation of resources
Answer:
0.4344A
Explanation:
From Ampere's law, it can be shown that the magnetic field B inside a long solenoid is

Where
B= Magnetic field strenght at distance d
I= current
Permeability of free space (
)
N= Number of loops
Our values are defined as follow,

T

As a current required to become 104 times the Earth's magnetic field is required, we use B '




<em>Therefore is needed 0.4344A in the solenoid to produce a magnetic field inside the solenoid, near its center, that is 104 times the Earth's magnetic field.</em>
Answer:
It cancels recoil.
Explanation:
For each action there is an equal an opposite reaction.
The principle of conservation of momentum tell us that if a single spore were ejected the fern would suffer a recoil from it. This recoil would take energy and speed from the spore. But if they are ejected in pairs the recoil is canceled and all the energy is transferred to the spores resulting in higher speeds.
