What is the formula for magnitude and direction?.

The momentum of one of the balls before the collision is 4.5 kg*m/s. The principle of conservation of momentum states that in an isolated system, the total momentum before a collision is equal to the total momentum after the collision.

If two objects are moving toward each other, then their relative velocity is twice the velocity of one object. Given that the total mass of the two bowling balls is 3 kg and the velocity of one of the balls before the collision is 3 m/s, we can use the equation of momentum p=mv to find the momentum of one of the balls.

p = mv

The momentum of one of the balls before the collision is p1 = m1*v1, where m1 is the mass of one of the balls and v1 is the velocity of one of the balls before the collision.

Given that the mass of one of the balls is 3 kg/2 = 1.5 kg.

p1 = (1.5 kg)(3 m/s) = 4.5 kg*m/s

Therefore, the momentum of one of the balls before the collision is 4.5 kg*m/s

The distance between the pivoting force and the resisting force is 1.2. Resistance is the capacity of a substance to block the movement of electrical current.

Resistance measures how easily energy will flow throughout a circuit by using the ohm () as the unit. Current increases when resistance decreases, and decreases when resistance increases. Resistance is important to ensure that water flows through circuits at the correct rate.

As resistance rises, the amount of current that flows diminishes. One of the causes, if abnormally high, could be conductivity damage from corrosion burning. Since all semiconductors emit some heat, temperature rise is a frequent issue connected to resistance.

       Alternating current supplied to the loudspeaker creates sound waves in the following way:

         A current in the coil creates a magnetic field around it. The magnetic field interacts with the permanent magnet generating a force, which pushes the cone outwards. The current changes direction.

  A change in the magnetic field through a coil can induce a potential difference across it which drives a current. The voltage and current changes in a transformer can be calculated, as power transfer is constant.

The motor effect is used inside headphones, which contain small loudspeakers. In these devices, variations in an electric current cause variations in the magnetic field produced by an electromagnet. This causes a cone to move, which creates pressure variations in the air and forms sound waves.

The end of the speaker cone is surrounded by a permanent magnet. A coil of wire which carries electrical signals is wrapped around the end of the cone. The movement generated causes the cone to vibrate.

When the momentum of each automobile is known, the after-collision velocity may be calculated by dividing the momentum by the mass (v=p/m). We can predict some things about the relative velocities before and after the impact if kinetic energy and momentum are conserved. Both before and after the impact, the relative velocity's magnitude is the same.

Gravity depends on mass, not on size or density.

Gravity is a force of attraction between two objects that have mass. The force of gravity is proportional to the product of the two masses and inversely proportional to the square of the distance between them. Therefore, the more massive an object is, the stronger the gravitational force it exerts.

Size and density are not directly related to gravity. Size is a measure of how big an object is, and density is a measure of how much mass is contained in a given volume. They do not affect the strength of the gravitational force. An object's size or density may affect the gravitational force acting on it, but only through their effect on the object's mass.

So, gravity depends on mass, but not on size or density. The gravitational force exerted by an object is proportional to its mass, regardless of its size or density.

The velocity of the block at 3.40 m from the top of the slope is 2.687 m/s.

Acceleration is the rate of change of velocity. Acceleration usually implies a change in velocity, but not always. If an object is moving in a circular orbit with constant velocity, it is still accelerating because the direction of its velocity is changing.

The acceleration of the block is m/s2

By the equation of motion,

With [tex]v^{2} -u^{2} =2as[/tex] and

3.82 = [tex]2*a*6.8[/tex]

=> 1a = 3.8²/6.8

Let v be the velocity 3.4 m from the vertex, then v2 = 2a3.4 = (3.8^2 /6.8)*3.4 = 3.8² /2

v = 3.8/√2 = 2.687
