Question

expression for work done when force and displacement are acting at an angle ____.

unit of electrical energy consumed_________

energy conversion in thermocouple ______

purpose of jack in lifting a car ______​

Answer 1

Answer:

1) W = F * d

2)joule

3)Thermocouple uses the seebeck effect where a solid-state device converts heat flux directly into electrical energy. The correct answer is thermocouple. ... This electric current is then measured with the help of a voltmeter or a microcontroller which converts the electric voltage to the temperature using a suitable format.

4 )A jack is used to lift a car to fix punctures in the wheels or other machinery located at the bottom of the car. Mechanical advantage will not change for a machine of given design. A pair of scissors is used to cut relatively soft substances like paper, cloth etc so it does not need high force to do such
