Answer:

°C = Density of water (g/cm3)

4° = 1.0000

20° = 0.9982

40° = 0.9922

60° = 0.9832

80° = 0.9718

Ciara is swinging a 0.015 kg ball tied to a string around her head in a flat, horizontal circle. The radius of the circle is 0.5

Marat540 [252]

Answer:

Option C

Explanation:

From the question we are told that:

Mass $m=0.015kg$

Radius $r=0.5m$

Time $t=0.70$

Generally the equation for Tension is mathematically given by

$T=\frac{4mr}{t^2} \pi$

$T=\frac{4*0.015*0.5}{(0.70)^2} (3.142)$

$T=0.60N$

Therefore

$T=0.60 N$ , toward the center of the circle

Which form of Kepler’s third law can you use to relate the period T and radius r of a planet in our solar system as long as the

ser-zykov [4K]

T2=r In the form of Kepler's law that can use to relate the period T and radius of the planet in our solar systems

<u>Explanation:</u>

<u>Kepler's third law:</u>

Kepler's third law states that For all planets, the square of the orbital

period (T) of a planet is proportional to the cube of the average orbital radius (R).

In simple words T (square) is proportional to the R(cube) T²2 ∝1 R³3

T2 / R3 = constant = 4π ² /GM

where G = 6.67 x 10-11 N-m2 /kg2

M = mass of the foci body

Can anybody help meh :(

Answer:

$n=1.56\times 10^{17}$ electrons

Explanation:

Given that,

Total charge = 9 mC = 0.009 C

0.009 C of charge passes through a wire in 3.6 s.

Let q' is the charge that passes through it in 10 s.

So,

$\dfrac{0.009 }{3.6}=\dfrac{q'}{10}\\\\q'=\dfrac{0.009 \times 10}{3.6}\\\\q'=0.025\ C$

We know that,

q = ne

Where

n is the number of electrons

So,

$n=\dfrac{q}{e}\\\\n=\dfrac{0.025}{1.6\times 10^{-19}}\\\\n=1.56\times 10^{17}$

So, $1.56\times 10^{17}$ electrons must pass through the cross-sectional area.
