components of the speed of the coin is given as
now the time taken by the coin to reach the plate is given by
now in order to find the height
so it is placed at 1.52 m height
Answer:
The time rate of change of the electric field between the plates is
Explanation:
From the question we are told that
The radius is
The distance of separation is
The current is
Generally the electric field generated is mathematically represented as
Where is the permitivity of free space with a value
So the time rate of change of the electric field between the plates is mathematically represented as
But
So
substituting values
Answer:
momentum =0
kinetic energy >0, positive
Explanation:
The final momentum is zero but the final kinetic energy is positive.
The momentum is zero because momentum is the sum of the mass×velocity for each component. momentum is conserved
The KE is positive because KE is the sum of the 1/2×mass×velocity^2.
Whereas velocity can be positive and negative since it is (it's what makes the momentum zero because on is positive and one is negative), the velocity squared will always be positive.
Adding together two positives will always be a positive number.
a=(5.8-1.5)÷15.8
a=4.3÷15.8
a=0.27m/s
Explanation:
acceleration=final velocity - initial velocity /time
Answer:
The value is
Explanation:
From the question we are told that
The radius of the cylinder is
The charge density of the plasma is
Generally the difference in potential energy of the Tritium ion before entering the cylinder and at the axis of the cylinder is mathematically represented as
Here
is the permitivity of free space with value
So
Generally from energy conservation we have that
Given that the velocity at the axis of the cylinder should be zero then
it means that the kinetic energy at this axis will also be zero
So
Here KE_i is the initial kinetic energy of the Tritium ion which is mathematically represented as
So
=>
=>
=>
=>
Here m is the mass of Tritium ion which is given in the question
