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.

When there's a hazard ahead, it's almost always quicker for you to steer away than to come to a full stop.

Hazard refers to any obstacle or other feature which causes risk or danger.

Living organisms respond to hazards via the production of adrenaline hormone. This hormone causes a flight response away from the hazard.

Therefore, when there's a hazard ahead, it's almost always quicker for you to steer away than to come to a full stop.

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.

The center of mass is the point located in an average position concerning the objects' positions and their masses. (a/3;a/3) is the location of the COM.  

The center of masses of a given system of particles or objects is the position under which all external forces are acting. Any uniform force acts on this point.

This position is the average position of all the components of the system concerning their masses. It can be placed in one, two or three dimensions according to the system.

Coordinate X of the center of masses is given by the following formula,

Xcom = Σ(Ximi) / Σmi

This is the adition (Σ) of each particle position on the X-axis (Xi) multiplied by their mass (mi), and the result divided by the summation of all masses -total mass-.

In the same way, coordinate Y of the center of masses is given by the following formula,

Ycom = Σ(Yimi) / Σmi

This is the adition (Σ) of each particle position on the Y-axis (Yi) multiplied by their mass (mi), and the result is divided by the summation of all masses.

The center of masses is located in the position (X, Y).

According to this framework, we can get the coordinates of the center of masses for this bidimensional system. Coordinates can be expressed in meters or centimeters (m or cm).

Data:

     Particle ⇒ (X;Y)

Coordinate X  ⇒  Xcom =  Σ(Ximi) / Σmi

                             Xcom =  (0m) + (0m) +(am) / m +m +m

                             Xcom =  am / 3m

                             Xcom =  a/3

Coordinate Y  ⇒  Ycom =  Σ(Yimi) / Σmi

                             Ycom =  (am) + (0m) +(0m) / m +m +m

                             Ycom =  am / 3m

                             Ycom =  a/3

Coordinates of the center of masses, (X;Y) = (a/3 ; a/3)

(a/3 ; a/3) is the location of the center of mass in the proposed bidimensional system.

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]

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
