The centre of mass of the region is bounded by y=9-x^2 y=5/2x, and the z-axis is (3.5, 33/8). Formulae used to find the centre of mass are as follows:x bar = (1/M)*∫∫∫x*dV, where M is the total mass of the system y bar = (1/M)*∫∫∫y*dVwhere M is the total mass of the system z bar = (1/M)*∫∫∫z*dV, where M is the total mass of the systemThe region bounded by y=9-x^2 and y=5/2x, and the z-axis is shown in the attached figure.

The two curves intersect at (-3, 15/2) and (3, 15/2). Thus, the total mass of the region is given by M = ∫∫ρ*dA, where ρ = density. We can assume ρ = 1 since no density is given.M = ∫[5/2x, 9-x^2]∫[0, x^2+5/2x]dAy bar = (1/M)*∫∫∫y*dVTherefore,y bar = (1/M)*∫[5/2x, 9-x^2]∫[0, x^2+5/2x]y*dA= (1/M)*∫[5/2x, 9-x^2]∫[0, x^2+5/2x]ydA...[1].

The limits of integration in the above equation are from 5/2x to 9-x^2 for x and from 0 to x^2+5/2x for y.To evaluate the above integral, we need to swap the order of integration. Therefore,y bar = (1/M)*∫[0, 3]∫[5/2, (9-y)^0.5]y*dxdy...[2].

The limits of integration in the above equation are from 0 to 3 for y and from 5/2 to (9-y)^0.5 for x.Substituting the values and evaluating the integral, we get y bar = (1/M)*[(9-5/2)^2/2 - (9-(15/2))^2/2]= (1/M)*(25/2)...[3].

Also, the x coordinate of the center of mass is given by,x bar = (1/M)*∫∫∫x*dVTherefore,x bar = (1/M)*∫[5/2x, 9-x^2]∫[0, x^2+5/2x]x*dA= (1/M)*∫[5/2x, 9-x^2]∫[0, x^2+5/2x]xdA...[4].

The limits of integration in the above equation are from 5/2x to 9-x^2 for x and from 0 to x^2+5/2x for y.To evaluate the above integral, we need to swap the order of integration. Therefore, x bar = (1/M)*∫[0, 3]∫[5/2, (9-y)^0.5]xy*dxdy...[5].

The limits of integration in the above equation are from 0 to 3 for y and from 5/2 to (9-y)^0.5 for x.

Substituting the values and evaluating the integral, we get x bar = (1/M)*[63/8]= (1/M)*(63/8)...[6]Thus, the centre of mass of the region is bounded by y=9-x^2 y=5/2x, and the z-axis is (3.5, 33/8).

Explanation:

The melting of the mantle beneath Reunion, an island located in the Indian Ocean, is primarily caused by heat transfer. The mantle is a layer of the Earth located between the crust and the core.

Reunion Island is situated above a hotspot, which is an area where a plume of hot material rises from deep within the Earth's mantle. As this plume ascends, it transfers heat to the surrounding mantle rocks, causing them to reach temperatures that are sufficient for melting to occur. The melting of the mantle generates magma, which eventually rises to the surface, forming volcanic activity on Reunion Island.

While heat transfer is the main driver of mantle melting beneath Reunion, other factors such as the addition of volatiles (gases and fluids) and changes in pressure can also play a role. The introduction of volatiles can lower the melting temperature of rocks, making them more prone to melting. However, the exact role of volatiles in the melting process beneath Reunion is not as significant as heat transfer.

Pressure changes can also influence melting, but in the case of Reunion, the effect is minimal. Melting occurs more readily as pressure decreases, which is why some melting is observed at shallower depths in the mantle. However, the pressure changes in the mantle beneath Reunion are not substantial enough to be the primary cause of melting.

A)  The speed of the radar waves = 3 x 10^8 m/s

B)  The distance between the aircraft and the target is 27 km.

C) It takes 100 seconds for the aircraft to be vertically above the target.

(a) The speed of the radar waves can be found using the formula:

speed of light = frequency x wavelength

Since radar waves are a type of electromagnetic waves and travel at the speed of light, we can use the above formula to find the speed of the radar waves:

speed of radar waves = speed of light = 3 x 10^8 m/s

(b) To find the distance AT between the aircraft and the target, we can use the formula:

distance = (speed x time) / 2

where speed is the speed of the radar waves (which we found to be 3 x 10^8 m/s), and time is the time taken for the radar waves to travel to the target and back (which is twice the time it took for the echo to be detected on the aircraft).

time taken for radar waves to travel to target and back = 2 x 90 us = 180 us = 1.8 x 10^-4 s

So, the distance between the aircraft and the target can be calculated as:

distance AT = (speed of radar waves x time taken for radar waves to travel to target and back) / 2

= (3 x 10^8 m/s x 1.8 x 10^-4 s) / 2

= 27 km

Therefore, the distance between the aircraft and the target is 27 km.

(c) To find the time which elapses before A is vertically above T, we can use the formula:

time = distance / speed

where distance is the horizontal distance between the aircraft and the target (which we found to be 27 km), and speed is the speed of the aircraft (which we were not given, but we can assume is constant).

Since the aircraft is flying at a constant speed, the time it takes to travel the horizontal distance between the aircraft and the target is the same as the time it takes for the aircraft to be vertically above the target. Therefore, the time which elapses before A is vertically above T is:

time = distance / speed

= 27 km / (270 m/s)

= 100 s

Therefore, it takes 100 seconds for the aircraft to be vertically above the target.

Answer: camels have humps to store fat which is then converted to energy when food is scarce ( the humps are not used for storing water )

The rotation of water in a toilet or sink drain is caused by a phenomenon known as the Coriolis effect. The Coriolis effect is a result of the Earth's rotation, which causes objects to move in a curved path relative to the Earth's surface. This is due to the fact that different parts of the Earth's surface rotate at different speeds.

In the Northern Hemisphere, the Coriolis effect causes water to rotate counterclockwise as it moves towards the drain. This is because the Earth's rotation causes objects to be deflected to the right in the Northern Hemisphere. Similarly, in the Southern Hemisphere, the Coriolis effect causes water to rotate clockwise as it moves towards the drain.

If water were forced up the drain, the direction of rotation would not reverse. The Coriolis effect would still cause the water to rotate in the same direction, regardless of whether it is moving towards or away from the drain. However, the effect may be less noticeable due to the force of the water being pushed up the drain. #SPJ11

To calculate the normal force exerted by the seat of the car on the passenger when the car is at the bottom of the depression, we need to consider the forces acting on the passenger.

At the bottom of the depression, the passenger experiences an inward net force directed towards the center of the circular path. This force is provided by the normal force exerted by the seat. To determine the normal force, we need to consider the centripetal force acting on the passenger.

The centripetal force can be calculated using the formula:

F_c = m * a_c

where F_c is the centripetal force, m is the mass of the passenger, and a_c is the centripetal acceleration.

The centripetal acceleration is given by:

a_c = v² / r

where v is the velocity of the car and r is the radius of the circular depression.

Given:

Velocity of the car (v) = 10 m/s

Radius of the depression (r) = 30 m

Mass of the passenger (m) = 60 kg

First, we calculate the centripetal acceleration:

a_c = (10 m/s)² / 30 m = 100 m²/s² / 30 m = 10/3 m/s²

Now, we can calculate the centripetal force:

F_c = (60 kg) * (10/3 m/s²) = 200 N

Since the normal force exerted by the seat is equal to the centripetal force, the normal force is 200 N. Therefore, the normal force exerted by the seat on the 60 kg passenger at the bottom of the depression is 200 N.

A. The average drift speed of the electrons in the wire is  1.19 x \(10^{-3}\)cm/s.

B. The time it would take an electron to travel 8.84 m is 7.43 x \(10^{5}\)sec

(A) To find the average drift speed of electrons in a wire, we can use the equation:

I = nAvq

Where:
I is the current in Amperes
n is the electron density in electrons per \(cm^{3}\)
A is the cross-sectional area of the wire in \(cm^{2}\)
v is the average drift velocity of electrons in cm/s
q is the charge of an electron, which is 1.6 x \(10^{-19}\) Coulombs

First, we need to find the cross-sectional area of the wire. The formula for the area of a circle is:

A = π\(r^{2}\)

Where:
A is the area of the circle
r is the radius of the circle

Given that the wire diameter is 1.63 mm, we can find the radius by dividing it by 2:

r = 1.63 mm / 2 = 0.815 mm = 0.0815 cm

Now, we can calculate the area:

A = \(π(0.0815 cm)^{2}\) = 0.0209 \(cm^{2}\)

Next, we can rearrange the equation to solve for v:

v = I / (nAq)

Given that the current is 20 A and the electron density is 8.47 x \(10^{24}\)electrons per \(cm^{3}\), we can substitute these values into the equation:

v = 20 A / (8.47 x \(10^{24}\) electrons per cm^3 * 0.0209 cm^2 * 1.6 x \(10^{-19}\) C)

Simplifying the expression:

v = 1.19 x \(10^{-3}\) cm/s

Therefore, the average drift speed of electrons in the 14 gauge wire carrying a maximum current of 20 A is approximately 1.19 x \(10^{-3}\) cm/s.

(B) To calculate the time it would take for an electron to travel a distance of 8.84 m, we can use the formula:

t = d / v

Where:
t is the time in seconds
d is the distance in meters
v is the average drift velocity of electrons in meters per second

Given that the distance is 8.84 m and the average drift velocity is 1.19 x 10^-3 cm/s, we need to convert the velocity to meters per second:

v = 1.19 x \(10^{-3}\) cm/s * 0.01 m/cm = 1.19 x \(10^{-5}\) m/s

Now, we can substitute the values into the formula:

t = 8.84 m / 1.19 x \(10^{-5}\)m/s

Simplifying the expression:

t = 7.43 x \(10^{5}\)s

Therefore, it would take approximately 7.43 x \(10^{5}\) seconds for an electron to travel a distance of 8.84 m.

According to given information,the speed of the proton accelerated through a potential difference of (6.0×10³)V is approximately 1.07×10⁵ m/s.

The speed of a proton that has been accelerated from rest through a potential difference of (6.0×10³)V can be calculated using the formula:

speed = √(2qV / m)

where:
- speed is the velocity of the proton,
- q is the charge of the proton (1.6×10⁻¹⁹ C),
- V is the potential difference (6.0×10³ V),
- m is the mass of the proton (1.67×10⁻²⁷ kg).

Plugging in the given values into the formula, we get:

speed = √(2(1.6×10⁻¹⁹C)(6.0×10³ V) / 1.67×10⁻²⁷ kg)

Simplifying the equation further:

speed = √(1.92×10⁻¹⁹ J / 1.67×10⁻²⁷ kg)

Next, we divide the numerator by the denominator to obtain the final value:

speed = √(1.15×10¹¹ m²/s²)

Therefore, the speed of the proton is approximately 1.07×10⁵ m/s.

Conclusion, The speed of the proton accelerated through a potential difference of (6.0×10³)V is approximately 1.07×10⁵ m/s.

B  = 22.40º

According to Snell's law:

n1 sinФ1 = n2 sinФ2

sin B / sinФ = n1 / n2

sinФ = (sin 22.40º) * ( 1/ 1.59)
