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
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 already answered the question. Both cars are traveling at 70kmph, which is 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!
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?
The opposite is perpendicular (a straight line that hits another at a right angle).
An antivortex is a vortex which rotates in an opposite direction to another with which it is paired.
equal, oppositewhen a force is exerted another force occurs that is equal in size and opposite in direction.wish that helps you. ^ ^

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.
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.
Force changes either the speed or the direction of motion, or both.
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.

THIS IS A GOOD QUESTION IF WE PLACE THE CHARGE IN THE ELECTRIC FIELD AT A DISTANCE R FROM THE ELECTRIC FIELD AND PLACED THE ANOTHER POINT CHARGE AT A ANOTHER DISTANCE r WHERE R IS GRATER THAN THE SMALL R THEN THE ELECTRIC FIELD AT r IS MORE THAN THE ELECTRIC FIELD AT POINT R.ORWE CAN SAY THAT IF THE CHARGE IS PLACED IN THE DIRECTION OF ELECTRIC FIELD THAN ITS ELECTROSTATIC POTENTIAL ENERGY WILL DECREASE OR WHEN IN DIRECTION OPPOSITE THAN VICEVERSA
1). Your speed in the forward direction should increase somewhat, since the recoil of the shot adds to your momentum. 2). The bullet you fire in the reverse direction leaves the muzzle with full muzzle velocity and momentum in the reverse direction ... in your frame of reference. Viewed by an observer in the stationary frame of reference ... the one in which you are moving at the speed of a bullet ... the one you fire just dribbles out of the muzzle and falls straight to the ground.
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).
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.
