In a Rutherford scattering experiment, each atom in a thin gold foil can be considered a target with a circular cross section. A

lpha particles are fired at this target, with the nucleus as the bull's-eye. The ratio of the cross-sectional area of the gold nucleus to the cross-sectional area of the atom is equal to 2.6 10-7. The radius of the gold atom is 1.4 10-11. What is the radius of the gold nucleus

Answer:

Explanation:

the cross-sectional area of the gold nucleus / the cross-sectional area of the atom  = 2.6 x 10⁻⁷

value of radius of gold atom = 1.4 x 10⁻¹¹

cross sectional area = π x (1.4 x 10⁻¹¹ )²

= 6.15 x 10⁻²²  Putting this value in the ratio above

the cross-sectional area of the gold nucleus / 6.15 x 10⁻²² = 2.6 x 10⁻⁷

the cross-sectional area of the gold nucleus = 16 x 10⁻²⁹

radius of nucleus R

π R² = 16 x 10⁻²⁹

R² = 5.1 X 10⁻²⁹

R = 7.14 x 10⁻¹⁵ .

The Lamborghini Huracan has an initial acceleration of 0.75g. Its mass, with a driver, is 1510 kg.
Cerrena [4.2K]

Answer:

11109.825 N

Explanation:

Given Data:

total mass =m=1510 kg

initial acceleration (a) =0.75g                  ( g=9.81 m/s² )

F=ma

  = (1510)*( 0.75*9.81)

  = 11109.825 N

How does a mirage occur in a deser?explain with a labelled diagram.​
Ronch [10]

Answer:

Mirages happen when the ground is very hot and the air is cool.

Explanation:

They happen when light passes through two layers of air with different temperatures. The desert sun heats the sand, which in turn heats the air just above it. The hot air bends light rays and reflects the sky.

When you see it from a distance, the different air masses colliding with each other act as a mirror.

In Trial III, a different, looser, spring is used; its force constant is 23.1 N/m. The suspended mass is the same as the one in
cricket20 [7]

Answer:

T=0.827s

Explanation:

The period of a spring can be calculated with the equation

T=2\pi w

But we know as well that w is given by,

w=\sqrt{\frac{k}{m}}

Replacing,

w=\frac{2\pi}{T}= \sqrt{\frac{k}{m}}\\T=2\pi\sqrt{\frac{k}{m}}\\T=2\pi\sqrt{\frac{0.4}{23.1}}

So we have that

T=0.827s
