When the compressor of an air conditioner starts up, it draws a current of 50 A. If the start-up time is 0.60 s, then the amount
7nadin3 [17]

Answer:

30 C

Explanation:

Given:

Current flowing in the circuit (I) = 50 A

Start-up time (t) = 0.60 s

Now, we know that, charge drawn in through a cross sectional area of the circuit is given as:

q=It

Where, 'q' is the amount of charge drawn, 'I' is the current and 't' is the start-up time.

Now, plug in 50 A for 'I', 0.60 s for 't' and solve for 'q'. This gives,

q=50\ A\times 0.60\ s\\\\q=30\ C

Therefore, the amount of charge drawn in the circuit at the start-up of the compressor of an air conditioner is 30 C.

Describe a situation where an object has a change in velocity but constant speed
arlik [135]
-- the little ball going round and round a spinning roulette wheel

-- a car driving around a curve in the road at a constant speed

-- any Earth satellite in a perfectly circular orbit.
The closest thing to it is a geostationary TV satellite ... they try hard
to make those orbits perfectly circular, and keep correcting them to
stay circular.
