Im not so sure but it should be the
instantaneous speed
Answer:
After the colision, the stationary electron's momentum is given as:
P = 2.7328 x 10^(-25) kg m/s
The direction of momentum is the same as the direction of velocity of the electron.
Explanation:
In an Isolated system, when an object moving at some velocity v collides head on with a stationary object of equal mass. There velocities are exchanged.
This means that the first electron will become stationary and the electron which was stationary initially will start moving at a velocity of 3*10^(5)m/s in the same direction as the first electron.
Post collision momentum of the stationary electron:
V = 3 x 10^5 m/s
m = 9.1093 x 10^(-31) kg
Momentum = P = mV = 9.1093 x 10^(-31) x 3 x 10^5
P = 2.7328 x 10^(-25) kg m/s
The direction of momentum is the same as the velocity of the electron.
Nebular hypothesis.
Explanation:
- The first version of the nebula hypothesis was proposed by Immanuel Kant and Pierre Laplace.
- Today the hypothesis has been revised to fit into more current and update realities about how our solar system emerged.
- The hypothesis is the widely accepted explanation to the origin and evolution of the solar system.
- It suggests that the star and the planets that makes up the solar system were products of a huge cloud of dust called the nebular.
- The nebular is a huge mass of interstellar dusts.
- The cloud collapsed and condensed under gravitational pull of the materials.
- A center core that resulted in the formation of our star, sun emerged and the rest of the particles formed our planet.

Answer:
electromagnetic waves need a medium to travel through
Answer: 0.078
Explanation:
Given variables:
R1 = 25.0 , R2 = 64.0 , I1 = 0.200
Step 1: find V
0.200 = v/25
0.200 * 25 = v
5 = v
Step 2: Solve for I2
I = V/R
I = 5/64
I = 0.078125
Hope this helps!
