Electric current refers to the perpetual motion of electrons in wire. Electric current for solid conductors is the flow of directed, negative-to-positive electrons from one atom to the next. Electrons and protons travel in the opposite directions in conductors such as liquids and gases where electric current is concerned. Electricity comes in two different forms: direct current (DC) and alternating current (AC) (AC). Electrons move just one way in direct current. DC is generated by batteries. Electrons flow both ways in alternating current. Always moving in the opposite direction are electrons. By convention, the direction of an electric current is the direction that a positive charge would move. Higher electric potential to lower electric potential is the direction in which current flows. Electrons move from a negative potential to a positive potential, and vice versa.

The sets of vectors that may represent the momenta of two objects after the collision is shown in the image attached.

If a moving object strikes an object at rest at an angle, after collision both the objects will move at right angles to each other. The final momentum vector may or may not be same in magnitude. If the moving object strikes the stationary object head on instead of at an angle, the moving object will become stationary and the stationary object will follow the moving object path. In this scenario both the objects are considered to have same size and mass.

If the object have different size, they bot will move at different velocities. If the moving ball is bigger, they both will move in the same direction. If the stationary ball is bigger, the stationary ball will follow the path of moving ball and the moving ball will go in exactly opposite direction.

Answer:

One arrow slightly up and to the right; one arrow slightly down and to the right.

Explanation:

Look at the picture.

Mike is swinging from a vine. The net force on Mike will be vertical upward at the bottom of the swing.

A centripetal force is a force that causes a body to move in a curved path. Its direction is always orthogonal to the motion of the body and towards the fixed point of the path's instantaneous center of curvature.

Mike is on a swing, which means he must take a circle course. In a circular motion, centripetal force acts towards the motion's center, allowing it to travel in that direction.

As a result, the net force at each point on the circular part will be towards the center. The direction of net force will be vertical upward at the bottom position.

Therefore, the net force on Mike will be vertical upward at the bottom of the swing

image is formed at a distance 10 cm in front of the mirror

the focal length of concave mirror is 8cm.

What is concave mirror ?

A concave or converging mirror has a reflective surface that is recessed inward (away from the incident light). A concave mirror reflects light inwards towards a focal point. They are used to focus light. Unlike convex mirrors, concave mirrors display different types of images depending on the distance between the object and the mirror.

The mirror is called a "collecting mirror". This is because they tend to collect the light that hits the mirror and refocus the parallel incident rays to a focal point. This is because the normal to the mirror surface is different at each point, so light is reflected at different angles at different points on the mirror.

Given u=40 cm (negative)

m=14 (negative for the real image)

a. From m=−vu,−14=−v(−40) or v=-10 cm

Thus the image is formed at a distance 10 cm in front of the mirror.

An object has positive acceleration when it is going faster than it was previously. Positive acceleration was demonstrated by the moving car in the first scenario. The acceleration will be in the same direction as that of the car's motion since the vehicle is moving ahead and accelerating.

Acceleration is the product of velocity and time. Therefore, velocity must be constant if acceleration is zero. Currently, that constant might be anything, such as 5 m/s. Additionally, a zero velocity also means a zero acceleration.

The velocity of the first vaulter at jump   v1   =   7.50   m/s

   Horizontal component of v1         v1x   =   v1 * cos ?1

  1.00   =   7.50 * cos ?1

   ?1   =   cos-1 (1.00 / 7.50
