Answer:

counter clockwise

Explanation:

The observer in the Northern Hemisphere will notice that the stars near the NCP to move counter-clockwise

Counter - clockwise : The observer will observe this because the earth movement when viewed from the North pole is in a counterclockwise direction, hence the stars will appear to move in an ant-clockwise direction

Explanation:

The owl eats 42 prey in a week and 180 prey in a month.

To calculate how much the owl eats in a week and a month, we need to determine the number of prey consumed in each time period.

In a week:

The owl produces two pellets every 24 hours. So, in one day, it consumes 2 * 3 = 6 prey (since each pellet contains the remains of 3 prey).

In a week (7 days), the owl consumes 6 * 7 = 42 prey.

In a month:

Assuming a month has 30 days (though some months have 31 days or 28/29 days), we can calculate the number of prey consumed in a month.

In a day: 6 prey

In a month (30 days): 6 * 30 = 180 prey.

Hence, the owl eats 42 prey in a week and 180 prey in a month.

Complete Question:

A tungsten wire is 1.5 m long and has a diameter of 1.0 mm. A current of 60 mA flows through the wire. The resistivity of the wire is 5.6 * 10^-8 Ωm. What is the potential difference across the ends of the wire?

Answer:

Potential difference, V = 0.00642 Volts.

Explanation:

Given the following data;

Diameter = 1 mm to meters = 1/1000 = 0.001 m

Length = 1.5m

Current = 60mA = 60/1000 = 0.06 Amperes.

Resistivity = 5.6 * 10^-8 Ωm

To find the potential difference across the ends of the wire;

First of all, we would determine the cross-sectional area of the wire (circle);

[tex] Radius, r = \frac {diameter}{2} [/tex]

[tex] Radius = \frac {0.001}{2} [/tex]

Radius = 0.0005 m

Area of wire (circle) = πr²

Substituting into the above formula, we have;

Area  = 3.142 × (0.0005)²

Area = 3.142 × 2.5 × 10^-7

Area = 7.855 × 10^-7 m²

Next, we find the resistance of wire;

Mathematically, resistance is given by the formula;

[tex] Resistance = P \frac {L}{A} [/tex]

Where;

P is the resistivity of the material.

L is the length of the material.

A is the cross-sectional area of the material.

Substituting into the formula, we have;

[tex] Resistance = 5.6 * 10^{-8} \frac {1.5}{7.855 * 10^{-7}} [/tex]

[tex] Resistance = 5.6 * 10^{-8} * 1909611.712 [/tex]

Resistance = 0.107 Ohms.

Now, we can find the potential difference using the formula;

[tex] V = IR[/tex]

Where;

V represents voltage or potential difference measured in volts.

I represents current measured in amperes.

R represents resistance measured in ohms.

Substituting into the formula, we have;

[tex] V = 0.06*0.107[/tex]

Potential difference, V = 0.00642 Volts.

Answer:

B Eight light-minutes

Explanation:

In the case when the distance separated earth and the sun so here we orbit the sun for a 150 million km distance and the light moves would be 300,000 kilometers per second

Now divide this

= 150 million ÷ 300,000 kilometers per second

= 500 seconds

This 500 seconds represent 8 minutes and 20 seconds

Hence, option B is correct

B) Eight light-minutes

Answer:

magnetism and dipole-dipole interaction

Explanation:

Two magnets are attracting each other, one magnet is big and strong, the other is small and weak, the big magnet attracts the small magnet with a stronger force, and the attraction depends on the size of the magnet.

The attraction between two magnets varies, and that depends upon several factors such as the strength of the force of attraction, which determines the usefulness and functionality of magnets, for example, in industrial settings, strong magnets are often used to lift heavy loads, etc.

Hence, two magnets are attracting each other, one magnet is big and strong, the other is small and weak, the big magnet attracts the small magnet with a stronger force, and the attraction depends on the size of the magnet.

Answer:

The small pebble

Explanation:

Since the potential energy, P.E lost equals kinetic energy, K.E gained,

P.E = K.E

P.E = mgh = K.E

So, K.E = mgh where g = acceleration due to gravity and h = height of drop

Since h and g are constant

K.E ∝ m

So, the kinetic energy of the object is directly proportional to its mass. Thus, the object with the smaller mass has the lesser kinetic energy.

Since the object with the smaller mass is the small pebble, so the small pebble would have less kinetic energy as it crashes on the road at the bottom of the mountain.

basically, because the ball "weighs" more now, it will hit the ground quicker. so technically gravity is more affective towards it. the piece of paper kind of floats it's way down. gravity isn't pushing on one force more, but because because the ball weighs more, it technically would be said so. hope this helps!

Answer:

Explanation:

Given that Two air craft P and Q are flying at the same speed 300m/s. The direction along which P is flying is at right angles to the direction along which Q is flying. Find the magnitude of velocity of the air craft P relative to air craft Q

The relative speed will be calculated by using pythagorean theorem

Relative speed = sqrt(300^2 + 300^2)

Relative speed = sqrt( 180000 )

Relative speed = 424.26 m/s

Therefore, the magnitude of velocity of the air craft P relative to air craft Q is 424.26 m/s

Answer:

The law of inertia is another name for Newton's first law. Newton's first law states that an object will not change its motion or direction unless a force acts on it. An object at rest will stay at rest and an object in motion will stay in motion if there isn't any force acting on them.

Example: When a car uses its brakes to stop, you sometimes feel like you are sliding forward. That is because the inertia keeps you moving forward, even though the car stopped.

Explanation:

Answer:

Law of inertia is sometimes called Newtons First law of motion.

Newtons first law of motion states that"A body will continue to its state of rest or motion unless external force acted upon it.
