A train 120 metres long passes an electric pole in 12 seconds and another train of same length traveling in opposite direction in 8 seconds what is the speed of the second train?

Completely ignore the first train.
The second train passes the pole in 8sec.
In this 8 seconds the train drove 120 meters.
So the train has a speed of 15meters per second (120/8=15).
Answer: 15 (meters / second) = 54 km/h

If a car is traveling north at 100 kilometers per hour and another car is traveling in the opposite direction at the same speed Are their velocities the same?
No. Velocity includes a directional component. If the two were of the same mass and collided head-on, their velocities (being in the reverse directions) would cancel out.
You are in a car going 70 km h and another car passes you going in the opposite direction at 70 km h Do both cars have the same velocity Explain?
You already answered the question. Both cars are traveling at 70kmph, which is the same velocity.
You are in a car going 70 kmh and another car passes you going in the opposite direction at 70 kmh. do both cars have the same velocity?
No. Velocity is a vector, so it has both a magnitude and a direction. If the velocity of your car was heading in the positive direction, then the other car is moving in the negative direction. The velocities are NOT the same!
What total distance will be covered by traveling at 50 mph for 75 minutes?
Mandy is driving north of 50km/he. If his sister is driving another car at a velocity of -25km/hr, in what direction is she driving?
A car is traveling at a velocity of 70 km hr west to have the same velocity another car would have to travel at?
Another car would have to travel at 70 km/hr west.To have the same velocity, it must have the same speed toward the same direction.
If a car is traveling north at 100 kilometers per hour and another car is traveling in the opposite direction at the same speed Are their velocities the same?
No. Velocity includes a directional component. If the two were of the same mass and collided head-on, their velocities (being in the reverse directions) would cancel out.
What is an antivortex?
An antivortex is a vortex which rotates in an opposite direction to another with which it is paired.
When a force is exerted another force occurs that is----------------in size and ------------in direction?
equal, oppositewhen a force is exerted another force occurs that is equal in size and opposite in direction.wish that helps you. ^ ^
What is electron movement referred to as?
Electron movement is referred to as electric current. When electrons flow through a conductor, such as a wire, they carry electrical energy from one point to another. The direction of current flow is opposite to the direction of electron movement.
What is meant by negative vector?
A negative vector is a vector that has the opposite direction of the original vector but the same magnitude. It is obtained by multiplying the original vector by -1. In other words, if the original vector points in a certain direction, the negative vector points in the exact opposite direction.
What changes the direction of a force?
The direction of a force changes when another force acts in the opposite direction to oppose it, or when the object experiencing the force changes its own direction of motion.
You are in a car going 70 km h and another car passes you going in the opposite direction at 70 km h Do both cars have the same velocity Explain?
You already answered the question. Both cars are traveling at 70kmph, which is the same velocity.
If you are traveling at the speed of a bullet and then fired a bullet in the opposite direction what happens?
If you are already traveling at the speed of a bullet, firing another bullet in the opposite direction would cause the two bullets to separate at a total speed equal to the sum of their individual speeds. This is because the velocity of the bullet fired in the opposite direction would be added to the velocity of the already moving object. Both bullets would continue moving independently after being fired.
How can the electrical potential energy of a charged particle in an electric field be increased?
The electrical potential energy of a charged particle can be increased by moving it against the direction of the electric field. This requires performing work to overcome the attraction or repulsion between the charged particle and the electric field. The increase in potential energy is directly proportional to the work done against the field.
What particels with electric charges will attract one another?
Particles with opposite electric charges will attract one another. For example, a positively charged particle will attract a negatively charged particle. This is known as the principle of electric attraction.
What is the net movement of electric charges in a single direction?
The net movement of electric charges in a single direction is called electric current. This current flows through a conductor, such as a wire, and is responsible for carrying electrical energy from one place to another. It is measured in Amperes (A).
How can an object travelling in one direction be accelerated in another direction?
An object traveling in one direction can be accelerated in another direction by applying a force in the desired direction. This force will cause the object's velocity to change, leading to acceleration in the new direction. The acceleration will depend on the magnitude and direction of the force applied.
