If the mass of the Jupiter is 1.9*10 kg and radius is fbx loom what is acclerallon due to gravity on the supiter ?

Bond [772]

Answer:

$g=25.92\ m/s^2$

Explanation:

Given that,

The mass of the Jupiter, $M=1.9\times 10^{27}\ kg$

The radius of Jupiter, $r=69,911\ km=69911\times 10^3 km$

We need to find the acceleration due to gravity on Jupiter. The formula is

$g=G\dfrac{M}{r^2}$

Put all the values,

$g=6.67\times 10^{-11}\times \dfrac{1.9\times 10^{27}}{(69911\times 10^3)^2}\\\\g=25.92\ m/s^2$

So, the value of acceleration due to gravity on the Jupiter is $25.92\ m/s^2$ .

Which of the following are scalar quantities?

kirill [66]

Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. ... Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.

A 60cm long string of an ordinary guitar is tuned to produce the note a4 (frequency 440hz) when vibrating in its fundamental mod

pishuonlain [190]

Answer:

0.78 m

Explanation:

The relationship between wavelength and frequency of a wave is given by

$v=f \lambda$

where

v is the speed of the wave

f is the frequency

$\lambda$ is the wavelength

For the sound wave in this problem, we have

$f=440 Hz$ is the frequency

v = 344 m/s is the speed of sound in air

Substituting into the equation and re-arranging it, we find the wavelength:

$\lambda=\frac{v}{f}=\frac{344 m/s}{440 Hz}=0.78 m$
