If A is the area of a circle with radius r and the circle expands as time passes, find dA/dt in terms of dr/dt. dA dt = dr dt (b

Lorico [155]

Answer: $157.1 m^2/s$

Explanation:

Given

A is the area of circle with radius r

$A=\pi r^2$

Differentiate w.r.t time

$\frac{\mathrm{d} A}{\mathrm{d} t}=\pi \times 2\times \frac{\mathrm{d} r}{\mathrm{d} t}$

Also $\frac{\mathrm{d} r}{\mathrm{d} t}=1 m/s at r=25 m$

$\frac{\mathrm{d} A}{\mathrm{d} t}=\pi \times 2\times 25\times 1=157.1 m^2/s$

Calculate the speed of a satellite moving in a stable circular orbit about the Earth at a height of 4930 km .

svet-max [94.6K]

The speed of the satellite moving in a stable circular orbit about the Earth is 5,916.36 m/s.

<h3>Speed of the satellite</h3>

v = √GM/r

where;

M is mass of Earth
G is universal gravitation constant
r is distance from center of Earth = Radius of earth + 4930 km

v = √[(6.626 x 10⁻¹¹ x 5.97 x 10²⁴) / ((6371 + 4930) x 10³)]

v = 5,916.36 m/s

Thus, the speed of the satellite moving in a stable circular orbit about the Earth is 5,916.36 m/s.

What amount of energy is needed for an electron to jump from n = 1 to n = 4?

liberstina [14]

Answer:

$E=2.04\times 10^{-18}\ J$

Explanation:

We need to find the energy for an electron to jump from n = 1 to n = 4.

The energy in transition from 1 state to another is given by :

$E=\dfrac{-2.18\times 10^{-18}}{n^2}\ J$

The difference in energy for n = 1 to n = 4 is:

$E=-2.18\times 10^{-18}\times (\dfrac{1}{4^2}-1)\\\\E=2.04\times 10^{-18}\ J$

So, the required energy is equal to $2.04\times 10^{-18}\ J$ .
