A planet has a mass of 5.68 x 1026 kg and a radius of 6.03 x 107 m. What is the weight of a 65.0 kg person on the surface of this planet?

Answers

Weight is dependent on both the mass of the object and the gravitational pull of a planet. This is why people weigh differently on other planets, which have a different gravitational force. Using the formula W = G(m1)(m2)/r^2 where:

W = weight or force
G = Gravitational constant (not the same as g) = 6.67x10^-11 m^2/kg^2
m1 = mass of object 1 (person)
m2 = mass of object 2 (planet)
r = radius of planet

This gives a weight of 677.26 Newtons

The speed of sound is 330.0 m/s and the wave length of a particular sound wave is 33.0 meters. Calculate the frequency of the sound wave. A)11,000 Hz B)10.0 Hz C) 0.10 Hz D)9.1 x 10-5 Hz

Answers

Answer:

B). f = 10.0 Hz

Explanation:

As we know the relation between frequency, wavelength and speed is given as

$v = f \lambda$

here we know that

$v = 330 m/s$

$\lambda = 33 m$

now in order to find the frequency of the sound we can use above relation as

$f = (v)/(\lambda)$

plug in all values in it

$f = (330)/(33)$

$f = 10 Hz$

v: velocity of wave
f: frequency
L: wavelenght

v = fL => f = v/L => f = (330)/(33) => L = 10Hz

Prove that an electron cannot exist in the nucleus

Answers

We can say this is proved because electrons are having negative charges. If they lie inside the nucleus, they will be neutralised by the positive charges. Thus, the atom will have no charged particle and unstable. But an atom has both positive and negative charges.

I live in the city. It's always warmer in the city, compared to other areas, even at night. Why is that? The rain shadow effect makes surrounding areas cool and moist and the city warm and dry.
