Answer: Exothermic reactions are reactions or processes that release energy, usually in the form of heat or light. In an exothermic reaction, energy is released because the total energy of the products is less than the total energy of the reactants.

  1. In Exothermic reaction energy is Thrown/Relased to the surroundings.
  2. In endothermic reaction, energy is absorbed from the surroundings.

Trick to identify:-

  • Exothermic reaction has +∆H sign on product side
  • Endothermic reaction has -∆H sign on product side or +∆H sign on reactant side

A 63.3 kg wood board is resting on very smooth ice in the middle of a frozen lake. A 35.7 kg boy stands at one end of the board.
Vlada [557]

The velocity of the board relative to the ice is zero, since both are at rest.

<h3>What is relative velocity?</h3>

Relative velocity is the velocity of an object in relation to another reference object or point.

When two objects are travelling or moving with the same velocity in the same direction, the relative velocity one relative to the other is zero.

Also, when two objects are at rest, the relative velocity one relative to the other is zero.

Therefore, the velocity of the board relative to the ice is zero, since both are at rest.

The most recent evidence supporting the theory of plate tectonics would include A) GPS monitoring of plate speeds and movements.
Whitepunk [10]

A) GPS monitoring of plate speeds and movements.

Explanation:

The most recent evidence supporting the theory of plate tectonics would be GPS monitoring of plate speeds and movements.

A GPS is a Global Positioning System made up of series of components.

  • Plate tectonics theory is the movement of the earth's lithosphere relative to one another.
  • The recent advances uses a GPS system to monitor real-time movement of the plates.
  • The GPS system is made up of a system of satellite in space that communicates real-times locations to sensors on the earth surface.
  • From the sensors, observatory stations can know and duly observe how plates are moving.

Imagine that you are driving in your car with a heavy bag of groceries on the front seat and you slam on your brakes to stop. Th
Alexxx [7]

Answer:

The correct answer is inertia.

Explanation:

The heavy bag of groceries is initially within the inertia frame of the car. This indicates that the heavy bag acquires the same speed as the car.

When the car stops, the heavy bag continues to move forward with the speed it had due to the principle of inertia, which states the property that the bodies cannot modify by themselves the state of rest or movement in which they are.

Have a nice day!
