Answer:The electric field is zero and the potential is positive.
Explanation:
Two identical positive charges are separated by a certain distance and midway between charges two identical positive charges are placed near each other.
So the Electric field at midway is zero because the electric field due to both charges add up to give zero electric field.(because they point in opposite direction)
Potential is scalar quantity and charges are positive so they add up to give potential.
Answer:
Explanation:
Bimetallic strips are used in thermostats for measuring and controlling temperature. The strip is connected to a switch and as the temperature changes, the strip flexes and opens or closes a contact. They are also used in ovens for measuring temperature. An electromechanical thermostat typically contains either a bi-metal coil or a metal strip. When the temperature changes, this coil or strip will move, causing a vial containing mercury to tip to one side. The mercury flows to one end of the vial, signaling that the heating or cooling needs to be turned on.

Answer:
Frequency is 0.5 Hz and the wave speed is 10 m/s.
Explanation:
As we know that frequency is defined as the how many times the no of cycles repeat in one second so if the wave is vibrating up and down twice during 1 second then the frequency in 1 second is
Therefore frequency is 0.5 Hz.
Now the distance of wawe in each second is,
Now the wave velocity is,
Here, f is frequency, d is the distance, v is the wave velocity.
Substitute all the variables
Therefore the wave speed is 10 m/s.
