Let positive be west and negative be east because they
are contrasting in directions.
The forces are 4100, -830, and -1200
The sum of the forces is 4100 – 830 – 1200 = 2070 N.
Newton’s law F = ma is used.
2070 = 6800 a
Isolating a will give us 2070 / 6800 = a
a = 0.34 m/s^2
Answer:
They two waves has the same amplitude and frequency but different wavelengths.
Explanation: comparing the wave equation above with the general wave equation
y(x,t) = Asin(2Πft + 2Πx/¶)
Let ¶ be the wavelength
A is the amplitude
f is the frequency
t is the time
They two waves has the same amplitude and frequency but different wavelengths.
Answer:
The oldest stars in spiral galaxies are younger than the oldest stars in elliptical galaxies.
Explanation:
Spiral galaxies have a greater star formation than elliptical galaxies, since the latter contain less gas and dust. Therefore, the rate of creation of new stars is lower in elliptical galaxies. These galaxies are dominated by old stars, with a long evolution. While the spiral galaxies have stars with a faster evolution.
I used to play tag or run around a lot and sometimes i do these activities but its a lot less now that i am older
The correct answer to this qustion is velocity and time
