Answer:0.478 c
Explanation:
Given
mass of lighter Particle
mass of heavier Particle
speed of lighter particle
Let speed of heavier particle
and Momentum of the particle is given by
as momentum is conserved therefore
Answer:
A
Explanation:
Let's rule out some of the options. C makes no sense because static charges will create electric fields only, so the charge has to move. D makes no sense because monopoles do not exist. We can rule out B because when a charge is moving at a constant velocity. You can use Maxwell's equations and general relativity to figure out that at a constant velocity, you can't produce an electromagnetic wave because there is no magnetic field. Therefore the answer is A. When you have an oscillating or accelerating electric charge, you will produce an EM wave.
First, we calculate for the weight of the object by multiplying the given mass by the acceleration due to gravity which is equal to 9.8 m/s²
Weight = (14 kg)(9.8 m/s²)
Weight = 137.2 N
The component of the weight that is along the surface of the inclined plane is equal to this weight times the sine of the given angle.
Weight = (137.2 N)(sin 52°)
weight = 108.1 N
Answer:
F = 1200 N
General Formulas and Concepts:
<u>Forces</u>
Newton's Second Law of Motion: F = ma
- F is force (in N)
- m is mass (in kg)
- a is acceleration (in m/s²)
Explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>m</em> = 300 kg
<em>a</em> = 4 m/s²
<u>Step 2: Find Force</u>
- Substitute in variables [Newton's Second Law of Motion]: F = (300 kg)(4 m/s²)
- Multiply: F = 1200 N

To solve this exercise we will use the expression of the displacement in the aromatic movement in the two given points. Thus we will find the value of time as a function of frequency. In the end we will replace that value and find the time taken,
The expression for the displacement of the object in simple harmonic motion is
At the initial position the value of x is zero,
Now the expression for the displacement of the object in simple harmonic motion is
At the final position the value of x is -1.8cm
Replacing we have that
The total change in time will be
Replacing the value of the frequency we have that
Therefore the time taken for the displacement in the interval of x=0 to x=-1.8 is 0.05s
