She say give tow points and write the equation of the line with the two give points (1,5) and (-3,-5 )
500 N is the answer, you just tell that the moon is attracted towards the person because of the Earth's huge mass.
Answer:
Explanation:
y1 = 16.2/2 = 8.1 cm
d = 1.22 lambda D/y1
d = 1.22 x 657 x 10^-9 x 23.7/0.081
d = 2.35 x 10^-4 m = 234.52 um
Answer:
a. 340.13 m/s b. 680.26 m/s c. our wavelength doubles
Explanation:
a. speed of wave, v = fλ were f = frequency = 301 Hz and λ = wavelength = 1.13 m.
v = fλ = 301 Hz × 1.13 m = 340.13 m/s
b. If we double the frequency then f = 2 × 301 Hz = 602 Hz
v = fλ = 602 Hz × 1.13 m = 680.26 m/s
c. If the speed of the wave is still 340.13 m/s, if we cut the frequency in half, then frequency now equals f = 301 Hz/2 = 150.5 Hz.
Since v = fλ,
λ = v/f = 340.13 m/s ÷ 150.5 Hz = 2.26 m.
Since our initial wavelength λ₀ = 1.13 m,
λ/λ₀ = 2.26 m/1.13 m = 2.
So, λ = 2λ₀ our wavelength doubles
The masses are equal.
According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
I hope that this helps you!
