the gravitational force that earth exerts on the moon equals 2.03 x 10^20N. The moons mass is 7.35 x 10^22kg. What is the accele

Ghella [55]

The first time we read this, we think that we'll have to go look up a bunch of stuff about the gravitational constant, centripetal force, orbital mechanics, the Moon's period of revolution, and who knows whut owl !

But you know whut ? The only thing we need is Newton's 2nd law:

F = m A

Divide each side by m :

Acceleration = Force / mass

Acceleration = (2.03 x 10²⁰ Newtons) / (7.35 x 10²² kg)

Acceleration = (2.03 x 10²⁰ / 7.35 x 10²² kg) (m/s²)

<em>Acceleration = 0.00276 m/s²</em>

A simple harmonic transverse wave is propagating along a string towards the left direction as shown in the figure. figure shows

dimulka [17.4K]

Answer:

Amplitude = 5 cm (Heights)
Wavelength (λ) = 40 cm
Wave speed (v) = 12 m/s (Approx)
Time period (T) = 0.033 s (Approx)
Maximum particle speed (V) = 9.43 m/s

Explanation:

1) Amplitude

Amplitude = 5 cm (Heights)

2) Wavelength (λ)

Wavelength (λ) = 40 cm

3) Wave speed

Wave speed (v) = √ t / μ

Wave speed (v) = √ 3.6 / [25x10⁻³]

Wave speed (v) = 12 m/s (Approx)

4) Time period (T)

Time period (T) = 1/f = (λ)/v

Time period (T) = 0.40m / 12

Time period (T) = 0.033 s (Approx)

5) Maximum particle speed (V)

Maximum particle speed (V) = Aw

Maximum particle speed (V) = [0.05x2x3.14] / 0.033

Maximum particle speed (V) = 9.43 m/s
