Answer:

Ball with the initial velocity as 15m/s will reach larger distance horizontally on the ground.

Explanation:

Ball 'A' has less initial velocity compared to ball 'B'. Which means it will take more time to reach horizontally on the ground. Therefore, Ball 'A' will cover larger distance.

How can an element be identified using its emission spectrum?

posledela

The correct choice is C .

Technically, choice-A is the process involved. But it's already been done,
and widely published, and the spectrum of every element is easily available.

For you to take the time and go to the trouble of constructing the spectra
would be like inventing wheels if you want to ride a bicycle.

The hydronium ion concentration in an aqueous solution is [H+] = 5.3 x10-4 M. What is the hydroxide ion concentration? Is this s

VladimirAG [237]

Answer:a

Explanation:

Given

$[H^+]=5.3\times 10^{-4}\ M$

and $pH+pOH=14$

Also $pH=-\log [H^+]$

therefore $pH=-\log (5.3\times 10^{-3})$

$pH=-(-4-\log (5.3))$

$pH=3.275$

Thus $pOH=14-3.275$

$pOH=10.275$

and $pOH=-\log [OH^{-}]$

$[OH]^{-1}=10^{-10.25}$

$[OH]^{-1}=1.88\times 10^{-11}\ M$

As the pH is less than 7 therefore solution is acidic

Satellite A is orbiting Earth at an altitude of 500 km and Satellite B is orbiting 800 km above the surface . How does the veloc

sp2606 [1]

The velocity of Satellite A is 2% greater than velocity of satellite B.

The given parameters;

<em>Altitude of Satellite A = 500 km</em>
<em>Altitude of Satellite B = 800 km</em>

The forces acting on the Satellites are given as follows;

$F_c = \frac{mv^2}{r} \\\\F_g = \frac{GMm}{r^2} \\\\\frac{v^2}{r} = \frac{GM}{r^2}\\\\v^2 = \frac{GM}{r} \\\\v^2 r = GM\\\\v_1^2 r _1 = v_2^2 r_2\\\\v_A^2r_A = v_B^2 r_B\\\\(\frac{v_A}{v_B} )^2 = \frac{r_B}{r_A} \\\\\frac{v_A}{v_B} = \sqrt{\frac{r_B}{r_A} } \\\\\frac{v_A}{v_B} = \sqrt{\frac{(800,000\ + \ 6.4 \times 10^6}{(500,000\ + \ 6.4 \times 10^6} )} \\\\\frac{v_A}{v_B} = 1.02 \\\\v_A = 1.02 \ v_B$

$v_A = v_B( 100\% \ + 2\%)\\\\v_A = 100\%v_B \ + \ \ 2\% v_B\\\\v_A = v_B \ \ + \ 2\% v_B$

Thus, the velocity of Satellite A is 2% greater than velocity of satellite B.

NEED ANSWER ASAP what are the factors that affect the strength of a frictional force?

ololo11 [35]

It's not the second one since color has nothing to do with force. Also the third one isn't a factor since buoyant forces is the upward force of caused by fluid that opposes the object entering the liquid. The acceleration of the object and the mass of an object and how rough the surface are the only two factors in all the options.
