binary
eclipse
globular
open
Globular star clusters form from tightly packed groups and/or older ancient stars.
What are globular star clusters?Globular star clusters can be defined as ancient stars packed in a spherical and/or symmetrical shape.
Globular star clusters represent the most common types of groups (i.e., clusters) of ancient stars.
These groups of stars (globular) are characterized to be densest in the center of the cluster.
In conclusion, globular star clusters form from tightly packed groups and/or older ancient stars.

a car has a mass of 200kg. It is on a hill 1000m high. How much gravitational potential energy does the car have?
Answer:
Explanation:
PE = m * g * h
m = 200 kg
h = 1000 m
g = 9.81
PE = 200 * 9.81 * 1000
PE = 1962000 Joules

S. Explain the washing effects of detergents of soap and why detergents in warm water washes greasy
clothes even better
Answer:
Soaps and detergents are made from long molecules that contain a head and tail the detergent molecules also help to make the washing process more effective by reducing the surface tension of the water. Surface tension is the force which helps a blob of water on a surface hold its shape and not spread out.

Fundamentally, pressure is defined as force per unit area. What is the source of the force in a gas sample? A) The force is from gravity acting on the particles. B) The force is composed of the sum of the collisions only between gas molecules. C) The force is composed of the sum of the collisions only between the gas molecules and the container. D) The force is composed of the sum of all collisions--between the gas molecules, each other and the container. E) The force was imparted to the container in its initial filling, a transfer of momentum.
Answer:
Option C
Explanation:
Given
Pressure = Force /Area
For any gas sample, force is defined as basically the force exerted by the gas molecules when they strike the surface (with in which they are contained) and bounce back.
Hence, Option C is the correct
measure the thickness of the brake rotor. how thick is the brake rotor? please help I've Kittery spent forever trying to do this
Answer:
Explanation:
its reading the caliper
as the 0 lines up w the 1/8" mark, it is 1 1/8"
Answer:
The minimum thickness will be stamped somewhere. You see there's part numbers and other things here you might need to use a wire brush to kind of clean it up but that's the thicknessUse a micrometer at the thinnest point on the surface of the rotor where it meets the pads to measure the minimum operational thickness. If your rotor needs to be cut or has worn passed this thickness, you'll need new rotors. You may also discover your rotor has Disc Thickness Variation.
An air track car with a mass of 0.55 kg and velocity of 5.8 m/s to the right collides and couples with a 0.45 kg car moving to the left with a velocity of 3.9 m/s. What is the combined velocity of the cars just after the collision?
Explanation:
Given:
m1 = 0.55 kg
m2 = 0.45 kg
vi1 = +5.8 m/a
vi2 = -3.9 m/a
Solve for V
m1vi1 + m2vi2 = (m1 + m2)V
(0.55 kg)(+5.8 m/s) + (0.45 kg)(-3.9 m/s) = (0.55 + 0.45)V
V = +1.46 m/a
This means that the combined mass after the collision is moving to the right at 1.46 m/s

Newton's First Law state
For every action there is an equal and opposite reaction.
An object in motion stays in motion unless acted upon by an unbalanced force.
Gravity acts on all objects that have mass.
Force= mass x acceleration
Answer: an object in motion stays in motion unless acted upon by an unbalanced force
Explanation: this is Newton’s first law of motion, which states that an object, whether in a moving or resting state, will continue to stay in that state unless there is an unbalanced force that changes that state. For a moving object, an example would be friction worth the ground. For a resting object, an example would be the force of a push.

A 19 kg ball has an initial velocity of 10 m/s. How much energy will be transformed into gravitational force?
Answer:
E = 950 J
Explanation:
The total amount of energy that can be transformed into gravitational energy will be equal to the kinetic energy of the ball at initial state:
[tex]E = K.E = \frac{1}{2} mv^2[/tex]
where, E = Energy = ?
m = mass of the ball = 19 kg
v = initial speed of the ball = 10 m/s
Therefore,
[tex]E = \frac{1}{2} (19\ kg)(10\ m/s)^2[/tex]
E = 950 J

Fermi energy of conduction electrons in silver is 0.548 J. Calculate the number of such electrons in unit cm3
Answer:
[tex]n=1.86*10^{-30}m^3[/tex]
Explanation:
From the question we are told that:
Fermi energy of conduction electrons [tex]E_f=0.548J[/tex]
Generally the equation for Fermi energy is mathematically given by
[tex]E_f=\frac{3}{\pi}^2/3*\frac{h^2}{8m}*{n^{2/3}}[/tex]
[tex]E_f=\frac{3}{\pi}^2/3*\frac{h^2}{8m}*{n^{2/3}}[/tex]
[tex]{n^{2/3}}=\frac{E_f}{\frac{3}{\pi}^2/3*\frac{h^2}{8m}}[/tex]
Where
h= Planck's constant
[tex]{n^{2/3}}=\frac{E_f}{\frac{3}{\pi}^2/3*\frac{h^2}{8m}}[/tex]
[tex]{n^{2/3}}=\frac{0.548J}{3.62*10^{-19}}[/tex]
[tex]n=(1.51*10^{-20})^{3/2}[/tex]
[tex]n=1.86*10^{-30}m^3[/tex]

Un cuerpo se mueve por una carretera que tiene rozamiento.¿Podríamos aplicar el principio de conservación de la energía mecánica? ¿Qué requisitos se han de cumplir para poder aplicarla?
Answer:
Sí se puede aplicar el Principio de Conservación de la Energía Mécanica siempre y cuando se considere los efectos de pérdida de energía a causa del rozamiento, de lo contrario, no se cumpliría el requisito de conservación derivado del citado principio de conservación.
Explanation:
Consideremos que el cuerpo representa nuestro sistema de estudio, el cual se desplaza por una carretera y experimenta rozamiento, significando cambios en la energía cinética y potencial gravitacional. La presencia de rozamiento indica una disipación de la energía del cuerpo, cuya energía mecánica total disminuye, significando un sistema no conservativo.
Sí se puede aplicar el Principio de Conservación de la Energía Mécanica siempre y cuando se considere los efectos de pérdida de energía a causa del rozamiento, de lo contrario, no se cumpliría el requisito de conservación derivado del citado principio de conservación.

What is the amount of work done when JoAnne throws a baseball 2 meters at a force of 40
newtons?
Answer:
Amount of work done by Joanne = 80 joule
Explanation:
Given:
Displacement of ball = 2 meters
Force applied = 40 newtons
Find:
Amount of work done by Joanne
Computation;
Work done = Force applied x Displacement
Amount of work done by Joanne = Force applied x Displacement of ball
Amount of work done by Joanne = 40 x 2
Amount of work done by Joanne = 80 joule
