The sequence that correctly lists earthquake waves from strongest to weakest is : ( C ) P waves -- S waves-- Surface waves

P waves are the strongest waves because they move more rapidly inside the incompressible earth core sending its energy at a hazardous rate, while the S waves are slower and produces vertical movement of the earth surface.

The weakest waves are the S waves which sweeps across the outer surface of the earth and they are also the slowest of all the waves.

Hence we can conclude that the sequence that correctly lists earthquake waves from strongest to weakest is P waves -- S waves-- Surface waves

It can be inferred from this statement that the detection of short bursts of radio waves or fast radio bursts is very common.

Fast or Short radio bursts, are intense, millisecond-long bursts of radio waves with unknown origins.

Since the first FRB was discovered in 2007, hundreds of these brief cosmic flashes have been shown to originate from several, far-off locations throughout the universe.

A significant portion of FRBs emit extremely brilliant radio waves that last only a few milliseconds at most before entirely vanishng, and about 10% of them have been seen to repeat and exhibit patterns.

The source's identity is still unknown due to the isolated character of the observed occurrence. Although a magnetar has been recognised as a potential source, as of 2022, there is no widely acknowledged single explanation.

Given that the bursts barely last a few milliseconds, the sources are assumed to be little larger than a few hundred kilometres.

Explanation:

both gravitational force and speed will increase

The gravitational force will increase and speed will decrease. So, the correct option is c.

Any two objects in the universe are attracted towards each other by the gravitational force, regardless of whether their masses are equal or not.

Here,

Newton's universal law of gravitation states that the force of attraction between any two bodies is inversely proportional to the square of the distance between them and directly proportional to the product of their masses.

So, the gravitational force of the satellite,

F ∝ 1/R²

where R is the radius of the circular orbit.

The equation for speed of the satellite is given by,

v = √Rg

where g is the acceleration due to gravity.

So, the speed is directly proportional to the square root of the radius of the orbit.

v ∝ √R

Therefore, as a result of the decrease in the radius of the orbit, the gravitational force of the satellite will increase, and its speed will decrease.

Hence,

The gravitational force will increase and speed will decrease.

Explanation:

ajjkiikkkkkhglutfgkitfgghiiij

Answer:

a)40 meters

b)2 m/s

c)2 m/s

d)0 m/s

e)45 degrees northeast

Explanation:

a) The displacement from C to A is the distance directly across the river, which is 40 meters.

b) The speed of the boat as seen by people standing at A is the magnitude of the boat's velocity vector, which is equal to the displacement divided by the time taken:

Speed = displacement / time = 40 m / 20 s = 2 m/s.

c) Let v be the speed of the water in the river. The boat is moving at right angles to the flow of the river, so the water exerts a perpendicular force on the boat. The time taken for the boat to travel from A to C is 20 seconds, during which time the boat will have been carried downstream by the river by a distance equal to v times the time taken.

Distance carried downstream = v × time = v × 20 m.

Since the boat landed at C, which is directly across the river from A, the distance it traveled horizontally is 40 meters. Therefore:

40 m = (boat speed) × (time taken) = (boat speed) × 20 s.

Hence, the speed of the boat is:

Boat speed = 40 m / 20 s = 2 m/s.

So, we have two equations:

Distance carried downstream = v × 20 m

Boat speed = 2 m/s

From the first equation, we get:

v × 20 m = 40 m

Therefore, the speed of the water in the river is:

v = 40 m / 20 m = 2 m/s.

d) The speed of the boat as seen by a fish drifting with the river is the difference between the speed of the boat and the speed of the water in the river:

Boat speed - Water speed = 2 m/s - 2 m/s = 0 m/s.

So, the speed of the boat as seen by a fish drifting with the river is zero.

e) The boat should head in a direction that makes its velocity vector point directly from A to B. Since A and B are directly opposite each other, this means the velocity vector should be perpendicular to the line connecting A and B.

We know the boat's velocity vector has a magnitude of 2 m/s and is at right angles to the velocity vector of the water in the river, which has a magnitude of 2 m/s. So, we can draw a vector diagram with the velocity vector of the boat pointing straight up and the velocity vector of the water pointing straight to the right. The vector connecting the tail of the water velocity vector to the head of the boat velocity vector will then point directly from A to B.

The angle between the boat's velocity vector and the line connecting A and B can be found using trigonometry. Let θ be this angle. Then:

tan(θ) = (boat speed) / (water speed) = 2 m/s / 2 m/s = 1.

Taking the inverse tangent of both sides gives:

θ = tan^(-1)(1) = 45°.

So, the boat should head in a direction 45 degrees to the right of straight up, or northeast.

Answer:The correct answer is mass

Using Newton's second law and kinematics we find that the correct answer are:

Kinematics studies the motion of bodies, establishing relationships between the position, velocity and acceleration of bodies.

               v = v₀ + a t

                y = v₀ t + ½ a t²

Where v i de veloicity, a the acceleration,y the position and t the time

Newton's second law states that force is proportional to the mass and acceleration of bodies

               F = ma

Where F es the force, m the mass ( scalr) and a de acceleraction

In the experiment shown, the car starts with zero initial velocity from a zero initial position, as the hanging mass creates a force that pulls the car, it increases its position and speed as time stops.

Therefore the position and speed are changing with time.

As the hanging mass is constant the applied force is constant consequently due to Newton's second law the mass of the body and its acceleration must be constant

In summary the acceleration, the mass and the applied force are constant.

The variable magnitude with time is the speed

Answer:

a. i) The pressure drop per unit length is 52,151.89 Pa

ii) The atmospheric pressure ≈ 19.175 × The pressure drop along 10 cm length of aorta

b i) The power required for the heart to push blood along a 10 cm length of aorta, is 2.6075945 Watts

ii) The basal metabolic rate ≈ 38.35 × The power to push the blood along a 10 cm length of aorta

c. i) Please find attached the drawing for the velocity profile created with Microsoft Excel

ii) The velocity at the center is approximately 2.04 m/s

Explanation:

The given diameter of the aorta, D = 2.5 cm = 0.025 m

The maximum flow rate, Q = 500 cm³/s = 0.0005 m³/s

Assumptions;

The blood flow is laminar

The blood is a Newtonian fluid

The viscosity of water ≈ 0.01 poise = 1 cp

a. i) The pressure drop per unit length of pipe ΔP/L is given by the Hagen Poiseuille equation as follows;

\(Q = \dfrac{\pi \cdot R^4}{8 \cdot \mu} \cdot \left(\dfrac{\Delta p}{L} \right)\)

Where;

Q = The flow rate = A·v

A = The cross sectional area

R = The radius = D/2

Δp/L = The pressure drop per unit length of the pipe

Therefore, we have;

\(\dfrac{\Delta p}{L} = \dfrac{Q\cdot 8 \cdot \mu }{\pi \cdot R^4} = \dfrac{0.0005 \times 8 \times 1}{\pi \times 0.0125^4 } = 52151.89\)

The pressure drop per unit length ΔP/L = 52,151.89 Pa

ii) The pressure, ΔP, drop along 10 cm (0.1 m) length of aorta = ΔP/L × x;

∴ ΔP = 52,151.89 Pa × 0.1 m = 5,215.189 Pa

Given that the atmospheric pressure, \(P_{atm}\) = 10⁵ Pa, we have;

\(P_{atm}\)/ΔP = 10⁵/5,215.189 ≈ 19.175

Therefore, the atmospheric pressure is approximately 19.175 times the pressure drop along 10 cm length of aorta

b. i) The power, P = Q × ΔP

Therefore, the power required for the heart to push blood along a 10 cm length of aorta, is P₁₀ = 0.0005 m³/s × 5,215.189 Pa = 2.6075945 Watts

ii) Therefore compared to the basal metabolic rate of, 'P', 100 W, we have;

P/P₁₀ = 100 W/2.6075945 Watts = 38.349521 ≈ 38.35

The basal metabolic rate is approximately 38.35 times more powerful than the power to push the blood along a 10 cm length

c. i) The velocity profile across the aorta is given as follows;

\(v_m = \dfrac{1}{4 \cdot \mu} \cdot \dfrac{\Delta P}{L} \cdot R^2\)

Where;

\(v_m\) = The velocity at the center

We get;

\(v_m = \dfrac{1}{4 \times 1} \times 52,151.89 \times 0.0125^2 \approx 2 .04\)

The velocity at the center, \(v_m\) ≈ 2.04 m/s

ii) The velocity profile, v(r), is given by the following formula;

\(v(r) = v_m \cdot \left[1 - \dfrac{r^2}{R^2} \right]\)

Therefore, we have;

\(v(r) = 2.04 - \dfrac{2.04 \cdot r^2}{0.0125^2} \right] = 2.04 - 163\cdot r^2\)

Answer:

C. The molecules will move more slowly

Explanation:

As the temperature in the system decreases, the random motion of the molecules decreases and as a result the molecules will move more slowly. So, option C is correct.

Intermolecular force is defined as the force of attraction or repulsion that mediates between the neighboring molecules in a system.

Here,

The water molecules in the system have more intermolecular distance between them and thus they are in random motion and are colliding among each other. These water molecules have lesser intermolecular force of attraction when compared to solids and higher than that of gas molecules.

When the temperature of the system decreases, the kinetic energy of the water molecules decreases which results in the reduced speed of the molecules. The intermolecular force of attraction between the molecules increases. As a result, the intermolecular distance between the molecules is decreased, thus the molecules comes more closer to each other. Due to this, the random motion of the water molecules in the system gets decreased which in turn causes the collision between the molecules become much lesser.

Hence,

As the temperature in the system decreases, the random motion of the molecules decreases and as a result the molecules will move more slowly.
