Sam constructs a circuit, connects a lead acid battery of 2 V to a lamp of resistance 3 Ω and places an ammeter across it. What must be the reading of the ammeter?

Answers

Answer 1

Answer:

0.67 Amps

Explanation:

As was pointed out in the comments, the fuse on this ammeter is likely to blow resulting in an error readout of 0.  To measure current, you measure in-line not across.  With that being said, let's assume that we are looking for the current of the circuit.  We can apply Ohm's law to find this value:

V = IR

V / R = I

I = V / R

I = 2V / 3Ω

I = 0.67 A

Assuming we had a very good ammeter and place it inline with the circuit, then we can say the reading will be 0.67A.

Cheers.

Resistance to impact is an example of a(n)

•thermal property.
•mechanical property.
•general physical property.

Answers

Answer:

Mechanical property

Explanation:

MECHANICAL PROPERTIES can be defined as the ability of a metal or material to remain undamaged after different type of forces has been applied or used on them because forces or loads are often applied to metal, material or physical properties which is why MECHANICAL PROPERTIES enables us to know the strength , toughness as well as the hardness of metal and the way this metal perform or react when different forces are applied on them.

Lastly any metal, material or physical properties that has the strength , hardness and resistance to withstand or remain unaffected despite the loads or forces use on them is an example of MECHANICAL PROPERTIES.

Therefore Resistance to impact is an example of a(n) MECHANICAL PROPERTIES.
