mr. tolman believes that our universe is expanding, but with all of the gravitational force from the celestial bodies of space,
marishachu [46]
Based on the description, it will be most likely that he believes in Oscillating model (also known as Cyclic model) of the universe

Based on this model, the gravitational force will prevent further expansion by pulling back the matters and undergo a bounce

hope this helps

Sí un auto viaja a 8m/s determine Tiempo en llegar a 200km de distancia Distancia que recorre en 40 minutos
GrogVix [38]

Answer:

a. Tiempo = 25000 segundos

b. Distancia = 19200 metros

Explanation:

Dados los siguientes datos;

Velocidad = 8 m/s

Distancia = 200 km a metros = 200 * 1000 = 200,000

Para encontrar el tiempo para cubrir la distancia anterior;

Tiempo = distancia/velocidad

Tiempo = 200000/8

Tiempo = 25000 segundos

b. Para encontrar la distancia recorrida en 40 minutos;

Tiempo = 40 minutos a segundos = 40 * 60 = 2400 segundos

Distancia = velocidad * tiempo

Distancia = 8 * 2400

Distancia = 19200 metros

What is the maximum angular momentum Lmax that an electron with principal quantum number n = 2 can have? Express your answer in
butalik [34]

Answer:

L_{max} = 1.414 ℏ

Given:

Principle quantum number, n = 2

Solution:

To calculate the maximum angular momentum, L_{max}, we have:

L_{max} = \sqrt {l(1 + l)}                              (1)

where,

l = azimuthal quantum number or angular momentum quantum number

Also,

n = 1 + l

2 = 1 + l

l = 1

Now,

Using the value of l = 1 in eqn (1), we get:

L_{max} = \sqrt {1(1 + 1)} = \sqrt 2

L_{max} = 1.414 ℏ

When a positively charged conductor touches a neutral conductor, the neutral conductor will:
frutty [35]

Answer:

Lose electrons

Explanation:

When a positively charged conductor touches a neutral conductor, the neutral conductor will lose electrons. Only electrons can move from one conductor to another, so if the neutral conductor ended up with a positive charge it means it lost electrons. The conductor touching and the neutral conductor both end up being charged positively.

According to general relativity, light : travels along a curve due to length contraction
Rama09 [41]

Answer:

travels along a curve due to uniform gravity

Explanation:

General relativity

The theory was developed by Albert Einstein , it is the theory of gravitation , according to which , the gravitation effect which is observed between the masses , is the resultant of their warping of the space time .

In general relativity , the equivalence principle is the equivalence of inertial gravitational mass .

According to which , the light bends due to gravitational forces ,therefore ,  the light travels along a curve because of uniform gravity .
