Answer:

Explanation:

The electronic configuration of many ions is that if a closes noble gas to them in a periodic table.

An Anion is a ion that has gained one or more electron, acquiring a negative charge.

A Cation is a ion that has lost one or more electron, gaining a positive charge.

Answer:

Total resistance is 19.6 Ω for the circuit .

Explanation:

Given:

Six resistors of a circuit namely $R_1$ to $R_6$ .

Where

$R_1$ and $R_2$ are in series.

$R_3$ and $R_4$ are in parallel.

$R_5$ and $R_6$ are in parallel.

We know that continuous resistor which are in series are added up to find the equivalent resistance.

Similarly resistors which are arranged in parallel their equivalent resistance is $\frac{R_3R_5}{R_3+R_5}$ for the case of $R_3$ and $R_5$ .

According to the question:

Total resistance = R(equivalent) :

⇒ $R_(eq_) = R_1+R_2+(\frac{R_3R_4}{R_3+R_4} )+(\frac{R_5R_6}{R_5+R_6} )$

⇒ $R_(eq_)=7+8+(\frac{4\times 6}{4+6} )+(\frac{3\times 8}{3+8} )$

⇒ $R_(eq_)=7+8+(\frac{24}{10} )+(\frac{24}{11} )$

⇒ $R_(eq_)=15+(2.4 )+(2.18)$

⇒ $R_(eq_)=19.58$ Ω

So the total resistance of the circuit depicted is 19.58 Ω approximated to nearest tenth that is 19.6 Ω

If you start rolling down this hill, your potential energy will be converted to kinetic energy. At the bottom of the hill ypu KE

Serjik [45]

Answer:

$v=\sqrt{(2x/m)}\ \ m/s$

Explanation:

Potential Energy= Kinetic Energy

Let $x$ be the value of Kinetic Energy.

We know that

$PE=KE=x\\x=\frac{1}{2}mv^2\\$

Make $v$ the subject of the formula to get speed at the bottom of the hill.

$v^2=2x/m\\v=\sqrt{2x/m}$

An SUV has a mass of 6000 kg and a compact car has a mass of 2000 kg. They both go around the same unbanked circular curve on th

Evgen [1.6K]

Answer:

Therefore, the centripetal acceleration of the SUV is <u>3 times</u> ao of the compact car.

Explanation:

FOR SUV:

$ac_{suv} = \frac{mv^2}{r}\\$

where,

ac_suv = centripetal acceleration of the SUV = ?

m = mass of SUV = 6000 kg

v = speed of SUV = vo

r = radius of path

Therefore,

$ac_{suv} = \frac{6000\ vo^2}{r}\\$ ---------------- equation (1)

FOR CAR:

$ao = \frac{mv^2}{r}\\$

where,

ao = centripetal acceleration of the car = ?

m = mass of car = 2000 kg

v = speed of car = vo

r = radius of path

Therefore,

$ao = \frac{2000\ vo^2}{r}\\$ --------------------- equation (2)

Dividing equation (1) by eq(2):

$\frac{ac_{suv}}{ao} = \frac{6000}{2000}\\\\ac_{surv} = 3ao$

Therefore, the centripetal acceleration of the SUV is <u>3 times</u> ao of the compact car.
