Explanation:
It is given that,
Velocity of the electron,
Magnetic field,
Charge of electron,
(a) Let is the force on the electron due to the magnetic field. The magnetic force acting on it is given by :
(b) The charge of electron,
The force acting on the proton is same as force on electron but in opposite direction i.e (-k). Hence, this is the required solution.
They use sound waves that bounce off walls, and other things back to them to feel where they are going.
To find the work done on the particle, the following is the
solution:
Dw = F dx
W = integral over the path ( F(x) dx)
W = integral from 0 to 1 (e^(-x/5 + 5) dx)
W = -5e^(-x/5 + 5) from 0 to 1
W = 135 J
The work done is 135 J.
Answer
given,
mass of block (m₁)= 8 kg
mass of other block (m₂) = 5.75
velocity of first object (v₁) = 5.5 m/s
velocity of second object (v₂) = 6 m/s
a) total momentum before collision = total momentum after collision
m₂v₂ - m₁ v₁ = (m₁ + m₂) V
5.75 x 6 - 8 x 5.5 = (5.75 + 8 ) V
V = - 0.69 m/s
b) negative sign shows the direction motion of object after collision toward left.
c) Initial kinetic energy
K_i = 224.5 J
final kinetic energy
=
=
K_f = 3.23 J
loss in mechanical energy
Δ KE = 3.23 - 224.5
Δ KE = -218.1 J
negative sign shows loss of mechanical energy.
