The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.

A small earthquake starts a lamppost vibrating back and forth. The amplitude of the vibration of the top of the lamppost is 7.0

krok68 [10]

Answer:

(a) T=6.07s

(b) $x_{max|4.0s}=3.62cm$

Explanation:

For Part (a)

The initial amplitude is given as A=7.0 cm

Apply the equation $x_{max}(t)=Ae^{-t/T}$ with $x_{max}(7.6s)=2.0cm$ we have:

$x_{max}(t)=Ae^{-t/T}\\2.0cm=(7.0cm)e^{-7.6s/T}\\T=-\frac{7.6s}{ln(\frac{2.0cm}{7.0cm} )} \\T=6.07s$

For Part (b)

Apply $x_{max}(t)=Ae^{-t/T}$ with t=4.0s and T=6.07s we have

$x_{max}(t)=Ae^{-t/T}\\x_{max}(4.0s)=(7.0cm)e^{-4.0/6.07}\\x_{max|4.0s}=3.62cm$

What is the mass of an object if a force of 34 N produces an acceleration of 4 m/s/s?

antoniya [11.8K]

Use newton's second law, F = ma.
Force is 34 N and a is 4 m/s/s
34 = m(4), solve for m.
34/4 = 8.5 g

Yes, young people have that ability. However, many of them do not use their ability wisely, and instead of contributing to their community, they only take.
