False
Answer:
8 minutes sooner
Explanation:
Average speed of snail= 4cm/min
Distance to be covered = 160cm
Time taken for the journey = distance/speed
Time taken for the journey = 160/4
Time taken for the journey = 40 min
If it crawed an average speed of 5cm/min
Distance = 160 cm
Time for the journey = distance/speed
Time for the journey = 160/5
Time for the journey = 32 min
Its going to take the snail 40 min - 32 min to Kno how sooner it will taje it if the average speed is 5cm/min
40 min - 32 min = 8 min
They move faster and move farther apart
Given Information:
Resistance = R = 250 Ω
Voltage = V = 3 V
Tolerance = ±5%
Required Information:
Maximum current = Imax = ?
Minimum current = Imin = ?
Answer:
Imax = 12.6 uA
Imin = 11.4 uA
Explanation:
As we know from Ohm's law
I = V/R
The current will be maximum when R is minimum and the current will be minimum when R is maximum
Rmax = 250,000 + 0.05*250,000
Rmax = 250,000 + 12500
Rmax = 262500 Ω
Rmin = 250,000 - 0.05*250,000
Rmin = 250,000 - 12500
Rmin = 237500 Ω
Imax = V/Rmin
Imax = 3/237500
Imax = 12.6 uA
Imin = V/Rmax
Imin = 3/262500
Imin = 11.4 uA
Answer:
Attractive Property – Magnet
Explanation:
attracts ferromagnetic materials like iron, cobalt, and nickel. Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other. Directive Property – A freely suspended magnet always points in a north-south direction.
