Reflection. It occurs when a wave bounces from the surface of an obstacle
The magnitude of average current is 2.02 * 10⁻¹⁴ A.
<h3 /><h3>What is current?</h3>
A stream of charged particles, such as electrons or ions, travelling through an electrical conductor or a vacuum is known as an electric current. The net rate of electric charge flowing through a surface or into a control volume is how it is calculated.
Number of electrons passing per second = 4910/ 0.0662 = 74169.18
Number of proton passing per second = 3485/0.0662 = 52643.50
current due to electrons,
I = ne
= 74169.18 * 1.6 * 10⁻¹⁹
= 1.18 * 10⁻¹⁴ A
current due to protons,
I = ne
= 52643.50 * 1.6 * 10⁻¹⁹
= 0.84 * 10⁻¹⁴ A
total current I = Ie + Ip
I =( 1.18 + 0.84 ) * 10⁻¹⁴ A
I = 2.02 * 10⁻¹⁴ A

Answer:
The baseball was falling during 1.733 seconds.
Explanation:
The baseball experimented a free fall, which is a particular case of uniformly accelerated motion, in which object is accelerated by gravity. In this case, we need to determine the time spent by the ball before hitting the ground (), measured in seconds, which is determined by the following kinematic formula:
(1)
Where:
, - Initial and final speeds of the baseball, measured in meters per second.
- Gravitational acceleration, measured in meters per square second.
If we know that , and , then the time spent by the baseball is:
The baseball was falling during 1.733 seconds.
Oxygon and Carbon are exchanged in the respiratory system hope this helps! :D

Explanation:
1. Air Resistance- this is a type of frictional force that acts upon objects as they travel through air. It usually opposes the motion of an object and it is mathematically difficult to predict its value.
2. Gravity- the force of gravity is the force that the earth, and moon use to attract an object towards itself. The moon has far less gravity than earth. All objects on earth experience a force of gravity that pulls them downward, towards the center of the earth.
3. Tension- the tension force is the force that is transmitted through a string, rope, cable or wire when it is pulled from opposite ends. The tension force is directed along the length of the wire and pulls equally on the objects on the opposite ends of the wire
4. Friction- this is the force exerted by a surface when an object moves across it. Friction results from the two surfaces being pressed together closely.
5. Electromagnetic force- although they don't seem similar, electricity and magnetism are related. Flowing electrons produce magnetism, and a moving magnet produces electricity.
6. Upthrust- this is the upward force that a liquid or gas exerts on a body floating in it.
7. Spring force- The spring force is the force exerted by a compressed spring upon any object that is attached to it. This object is always acted upon by a force that restores the object to its rest or equilibrium position.
8. Applied force- An applied force is a force that is applied to an object by a person or another object.
9. Electrostatic force- The types of forces exerted by all electrically charged bodies on another charged bodies in the universe are ‘electrostatic forces’. They can be either positively or negatively charged.
10. Nuclear force- these are the forces that act between two or more nucleons. They bind protons and neutrons into atomic nuclei. The nuclear force is about 10 millions times stronger than the chemical binding that holds atoms together in molecules.
