GIven data:
Distance between the plates = 1.5 mm
Potential difference V = 600V
Charge on electron q = -1.6× C
mass on electron = m = 9.1× Kg
Solution:
First we will find the change in potential energy of the charge while moving through the potential difference of 600V.
ΔU = qΔV
= (-1.6×)(600)
= -9.6×J
By the law of conservation of mechanical energy, as there is no external force acting, so the sum of the kinetic and potential energies will be a constant.
K + U = E
ΔK + ΔU = 0
ΔK = -ΔU
1/2mv² = -ΔU
v² = -2ΔU/m
=
v =
v = 1.45× m/s
Answer:
7.5 × 10^9 J.
Explanation:
So, we are given the following data or parameters or information for the proper solving of the question above;
=> ''actual force exerted by the tractor beam as a function of position is given by F(x) = ax + , where a = 6.1 x 10 N/mº and B = -4.1 x 10° N''
=> " Assume the supply spacecraft had an initial kinetic energy of KE = 2.7 x 10" J "
=> "that the tractor beam force is applied on the spacecraft over a distance of 7.5 x 10^11 m away.from its beginning position at = 0.0 m"
So, we can then solve it as;
KE2 – KE1 = F(x) dr.
KE2 - 2.7 x 10^11 J = - 3.5 × 10^6 × 7.5 x 10^4.
KE2 = 7.5 × 10^9 J.
Explanation:
answer is that velocity is the speed with a direction, while speed does not have a direction.
Answer:
mass and it's velocity
Explanation:
Momentum can be defined as mass in motion. All objects have mass, so if an object is moving, then it has momentum which implies mass in motion. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
