If a gas has the same temperature throughout, which gas molecule has the highest average velocity?

Answer:

Inertia

Explanation:

It is inertia that causes the passengers to move toward the right side of the car. As the car swerves to left, passengers' body continues their motion as hitherto and as such it causes the passengers to move toward the right side of the car.

For Acellus

Explanation:

The electric field equals the force exerted by the unit positive charge. The electric field at point P is 3.615×10⁶  N/C. Its unit is N/C.

When a charged particle is got influenced by another charged particle when bring near to it, a field is created by an electric charge. This field is called the electric field.

The electric field is obtained by taking the ratio between Force and unit positive charge. Force in a charge is because of attraction and repulsion. The SI unit of force is Newton (N).

The unit positive charge is the test charge used to analyze the other charges present in the field. The SI unit of charge is Coloumb (C). The charge is responsible for the creation of an electric field.

From the givens,

The charge  q₁ = q₂ = 5×10⁻⁸ C,

The distance of charges from point P, r₁ = 0.424 m; r₂ = 0.636 m.

The net electric field E = E₁ + E₂

Electric field E = F / q

 E₁ = kq₁ / r₁²          (k = 9×10⁹ Nm²/C²)

     =  9×10⁹× 5×10⁻⁸ / (0.424)²

  E₁   = 2.503×10³ N/C.

E₂ = kq₂ / r₂²

    = 9×10⁹× 5×10⁻⁸ / (0.636)²

E₂ = 1.112×10³ N/C

E = E₁ + E₂

  =2.503×10³ + 1.112×10³

  = 3.615×10³ N/C

Hence, the net electric field is 3.615×10³ N/C.

Explanation:

Cylinder A = 100g = 100*10^-3kg =0.1kg

Cylinder B = 300g = 300*10^-3kg = 0.3kg

gravitational force g= 9.81m/s^2

For cylinder A Force = mg= 0.1*9.8=0.98N

For Cylinder B Force = mg= 0.3*9.81= 2.943N

When a chunk of cosmic material the size of a golf ball or a baseball hits the Earth's atmosphere it makes a fireball.

Meteor shower is an event that occurs when tiny particles of stones that are of the size of a golf ball or baseball hits the earth's atmosphere.

As the particles enters the earth's atmosphere, they create friction through rubbing against the particles of the air. This eventually causes the particles to heat up leading to the formation of a fireball.

Meteor shower usually occurs between midnight and the very early hours of the morning.

Therefore, when a chunk of cosmic material the size of a golf ball or a baseball hits the Earth's atmosphere it makes a fireball.

a. The restoring force in the spring has magnitude

F[spring] = k (0.79 m)

which counters the weight of the mass,

F[weight] = (0.46 kg) g = 4.508 N

so that by Newton's second law,

F[spring] - F[weight] = 0   ⇒   k = (4.508 N) / (0.79 m) ≈ 5.7 N/m

b. Using the same equation as before, we now have

F[weight] = (0.75 kg) g = 7.35 N

so that

(5.7 N/m) x - 7.35 N = 0   ⇒   x = (7.35 N) / (5.7 N/m) ≈ 1.3 m

The height, h to which the package of mass m bounces to depends on its initial velocity, v and the acceleration due to gravity, g and is given below:

[tex]h = \frac{v^{2}}{2g}[/tex]

Perfectly elastic collisions are collisions in which the momentum as well as the energy of the colliding bodies is conserved.

In perfectly elastic collisions, the sum of momentum before collision is equal to the momentum after collision.

Also, the sum of kinetic energy before collision is equal to the sum of kinetic energy after collision.

Since some of the Kinetic energy is converted to potential energy of the body;

[tex]\frac{mv^{2}}{2} = mgh[/tex]
