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.

The cable holding a 2125 kg elevator has a maximum strength of 21,750 N. What is the maximum upward acceleration the cable can g
vivado [14]

Answer:

10.23m/s^2

Explanation:

GIven data

mass of elevator = 2125 kg

Force= 21,750 N

Required

The maximum acceleration upward

F= ma

a= F/m

a=21,750/2125

a= 10.23m/s^2

Hence the acceleration is 10.23m/s^2

A) use v=u+at for both

First section, v=27, u=0, a=2.4. You should get 11seconds.
Second section, v=0, u=27, a=-1.3. You should get 21seconds.
This means that the total time is 22seconds.

b) You can either use s=ut+0.5at^2 or v^2=u^2+2as. Personally, I would use the second one as you are not relying on your previous answer.

First section, v=27, u=0, a=2.4. You should get 152m.
Second section, v=0, u=27, a=-1.3. You should get 280m.
This makes your overall displacement 432m.

What happens to the gravitational attraction between 2 objects
amm1812

Answer:

It decreases.

Explanation:

between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases
