A milliammeter has an internal resistance of 5ohms and reads upto 20 millianmeter, cal the value of the resistance
that should beconnected to it to enable to read up to
5A

Rs = 0.02008 Ω = 20.08 mΩ

Explanation:

The range of an ammeter can be increased by connecting a small shunt resistance to it in a series combination. This shunt resistance can be calculated by the following formula:

where,

= value of shunt resistance = ?

= current range of ammeter = 20 mA = 0.02 A

I = Required range of ammeter = 5 A

= Resistance of ammeter = 5 ohms

Therefore,

Rs = 0.02008 Ω = 20.08 mΩ

the word that best describes martin luther king jr.'s tone in the video is dignified

martin luther king, jr. was a social activist and baptist minister who played a key role in the american civil rights movement from the mid-1950s until his assassination in 1968. the video shows his manner and attitude having or showing a composed or serious manner that is worthy of respect so dignified is the correct answer

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
