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.

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

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
Answer:
424.26 m/s
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

A small pebble and one large boulder start at the same height and begin rolling down the side of a mountain. Which object would have less kinetic energy as it crashes on the road at the bottom of the mountain? Justify your selection.
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.
Two charges of 5 x 10-6 C are a certain distance apart. These two positive charges experience 3.6 N of repelling electrical force between them. How far apart are these charges?
Answer:
r = 0.2499 m
Explanation:
Use Coulomb's Law: [tex]F_{e} = kq_{1}q_{2} / r^{2}[/tex] where Fe is the electric force, q1 and q2 are the 2 charges respectively, k is a constant (8.99*10^9 N • m^2 / C^2) and r is the distance.
[tex]3.6 N = (8.99*10^{9})(5*10^{-6})(5*10^{-6}) / r^{2}[/tex]
r = 0.2499 m
The distance that should be apart from these charges should be considered when the r = 0.2499 m.
Calculation of the distance apart:Since
Two charges of 5 x 10-6 C are a certain distance apart. These two positive charges experience 3.6 N of repelling electrical force between them
So
here we use Columb law
Electric force = k * two charges * two charges)r^2
3.6 N = (8.99*10^9) * ( 5 * 10^-6) * (5*10^-6)r^2
r = 0.2499 m.
Hence, The distance that should be apart from these charges should be considered when the r = 0.2499 m.

A 50kg gymnast is bouncing on a trampoline. If she is going down at 5m/s when she lands on the trampoline, and it bouncesher up in the opposite direction at a velocity of 4m/s, whatis her change in momentum?
Answer:
450 kgm/s upward
Explanation:
From the question,
Change in monentum = mass× change in velocity
ΔM = mΔv....................... Equation 1
ΔM = m(v-u).................. Equation 2
Where ΔM = Change in momentum, m = mass of the gymnast, v = final velocity, u = initial velocity
Given: m = 50 kg, v = -4 m/s. u = 5 m/s
Substitute these values into equation 2
ΔM = 50(-4-5)
ΔM = 50(-9)
ΔM = -450 kgm/s
Hence the change in momentum of the gymnast is 450 kgm/s upward
A student has two identical sheets of paper. He crumples one up into a small ball. If he drops the sheet of paper and the ball of paper off a building at the same time, which of the following statements describes the result?
A. The sheet of paper because it is more affected by gravity.
B. The ball of paper hits the ground first because it is more affected by gravity
C. The sheet of paper and the ball of paper hit the ground at the same time.
D. The ball of paper hits the ground first because it has less surface area.
Answer:
B
Explanation:
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:
the ball of paper, because it has less surface area.

HELP!!! I MIGHT FAIL THE 6th GRADE IF I DON'T GET HELP!!!! The southern United States experiences periodic occurrences of severe cold and drought conditions. Which weather phenomenon most likely causes this and why?
Answer:
La Niña, because the jet stream is displaced northwards
Explanation:
La Nina is known to be a cool phase that affects the average ocean temperature. During this period the surface wind becomes stronger and there is lesser rainfall over the areas of the central tropical Pacific to which the Southern United States belongs.
Hence, when the southern United States experiences periodic occurrences of severe cold and drought conditions, the weather phenomenon most likely causes this and why is "La Niña, because the jet stream is displaced northwards."

If the area of a concrete slap weighing 300n is 400cm2 ,how much pressure can it apply when kept on the ground
Answer:
7500 N/m²
Explanation:
From the question given above, the following data were obtained:
Force (F) = 300 N
Area (A) = 400 cm²
Pressure (P) =?
Next, we shall convert 400 cm² to m². This can be obtained as follow:
1×10⁴ cm² = 1 m²
Therefore,
400 cm² = 400 cm² × 1 m² / 1×10⁴ cm²
400 cm² = 0.04 m²
Finally, we shall determine the pressure. This can be obtained as follow:
Force (F) = 300 N
Area (A) = 0.04 m²
Pressure (P) =?
P = F/A
P = 300 / 0.04
P = 7500 N/m²
