Answer:

Compasses are mainly used in navigation to find direction on the earth. This works because the Earth itself has a magnetic field which is similar to that of a bar magnet. The compass needle aligns with the Earth's magnetic field direction and points north-south. Also, In a magnet all the domains are oriented in the same direction. In the case of a nail, the domains can be aligned in the same direction causing the nail to become magnetic. That is because if you hang a bar magnet from a thread, the north pole will point to magnetic north. When you bring one north pole close to another north pole they repel each other. You can feel the two magnets pushing each other apart.

In order to remove water from a flooded basement, two pumps, each rated at 45 gallons per minute, are used. After half an hour,
LenKa [72]

Answer:

4050 gallons

Explanation:

In first half and hour both pumps are working property . There for it give, 45

gallons per minute . Half and hour is equal to 30 minutes.After one pump was broken only one pump is working 30 minutes .

For 1st 30 minutes ,( 2 pumps are working )

Gallons = 45 * 30 *2 = 2700 gallons

2nd 30 minutes ( 1 pump is working )

Gallons = 45*30*1 = 1350 gallons

Total gallons = 2700+1350

= 4050 gallons

If the x-position of a particle is measured with an uncertainty of 1.00×10-10 m, then what is the uncertainty of the momentum in
yawa3891 [41]

Answer:

The uncertainty in momentum is 5.25x 10^25Jsm

Explanation:

We know that

h bar = h/2π

So

1.05x 10^34=h/2pπ

h=1.05x 10^ 34(2π)=6.597x 10^-34Js

dp=(6.597x10^-34/4pπ)/(1x10^-10)

=5.25x10^-25 Jsm

A radar transmits a signal towards an aeroplane. The velocity of the signal is 3.0 x 10^8 m/s. After 0.0036 s, the radar detects
avanturin [10]

The distance of the airplane from the radar will be 1.08×10⁶ m. Distance can refer to a physical length.

<h3>What is distance?</h3>

Distance is a numerical representation of the distance between two objects or locations.

The distance of the airplane from the radar is found by the formula;

Distance = velocity × time

Distance =  3.0 x 10^8 m/s× 0.0036 s,

Distance =  1.08×10⁶ m.

Hence, the distance of the airplane from the radar will be 1.08×10⁶ m.

To learn more about the distance, refer to the link;
