A mix

Explanation:

A battery is an electrochemical cell that converts chemical energy into electrical energy. The chemical reactions in a battery ensures that current is produced.

  • A battery is made up of two electrodes which are the cathode and anode.
  • The cathode is the positive electrode and the anode is the negative one.
  • These electrodes are made up of metals.
  • Electrons moves from the anode to the cathode and current flows from cathode to anode.
  • At the anode oxidation occurs because electrons are produced here.
  • It needs to have low electron affinity.
  • At the cathode where reduction occurs, the electron affinity must be high.
  • This is the driving force for the production of electricity in electrochemical cells.

What is the efficiency of a tractor that has a work output of 300j and a work input of 400j
Sauron [17]
<h3><u>Answer;</u></h3>

= 75 %

<h3><u>Explanation</u>;</h3>

To measure efficiency of a machine, compare the work output to work input.

Efficiency = Work output/ work output × 100 %

                = 300/400 × 100

                = 75 %

A 3.0-kg object moves to the right with a speed of 2.0 m/s. It collides in a perfectly elastic collision with a 6.0-kg object mo
Zinaida [17]

Answer:

The kinetic energy of the system after the collision is 9 J.

Explanation:

It is given that,

Mass of object 1, m₁ = 3 kg

Speed of object 1, v₁ = 2 m/s

Mass of object 2, m₂ = 6 kg

Speed of object 2, v₂ = -1 m/s (it is moving in left)

Since, the collision is elastic. The kinetic energy of the system before the collision is equal to the kinetic energy of the system after the collision. Let it is E. So,

E=\dfrac{1}{2}m_1v_1^2+\dfrac{1}{2}m_2v_1^2

E=\dfrac{1}{2}\times 3\ kg\times (2\ m/s)^2+\dfrac{1}{2}\times 6\ kg\times (-1\ m/s)^2

E = 9 J

So, the kinetic energy of the system after the collision is 9 J. Hence, this is the required solution.
