Answer:

D. Hydrogen has a valence of 1 and oxygen has a valence of 6

Explanation:

Electrons present in the outer most shell of an atom is known as valence electrons.

Here oxygen has 6 valence electrons in its outermost shell while hydrogen has only one valence shell in its outermost shell

So here if hydrogen share its one electron with oxygen then its electron configuration becomes stable and if oxygen share its two electrons of the shell with two different hydrogen atoms then this will stable the electron configuration of oxygen.

So in this way hydrogen and oxygen forms bonds with each other and its bond sharing electrons will form bond.

so here correct answer will be

D. Hydrogen has a valence of 1 and oxygen has a valence of 6

A child of mass 27 kg swings at the end of an elastic cord. At the bottom of the swing, the child's velocity is horizontal, and

snow_tiger [21]

Answer:

The magnitude of the rate of change of the child's momentum is 794.11 N.

Explanation:

Given that,

Mass of child = 27 kg

Speed of child in horizontal = 10 m/s

Length = 3.40 m

There is a rate of change of the perpendicular component of momentum.

Centripetal force acts always towards the center.

We need to calculate the magnitude of the rate of change of the child's momentum

Using formula of momentum

$\dfrac{dp}{dt}=F$

$\dfrac{dP}{dt}=\dfrac{mv^2}{r}$

Put the value into the formula

$\dfrac{dP}{dt}=\dfrac{27\times10^2}{3.40}$

$\dfrac{dP}{dt}=794.11\ N$

Hence, The magnitude of the rate of change of the child's momentum is 794.11 N.

Keith_Richards [23]

<span>Answer: F=GMm/r^2 where G is the newtonian grav cst, M the mass of the star, m the mass of the planet, and r the planet-star distance F1=GMm1/r1^2 F2=GMm2/r^2 F2/F1 = [GMm2/r2^2]/[GMm1/r1^2] F2/F1=(m2/m1)(r1/r2)^2 = (2)(1/2)^2 = 1/2 because m2/m1=2 and r2/r1=2</span>
