a small fish is subject to both a viscous force and a drag force from the water. if the fish swims twice as fast, what happens to these forces?

Answer:

The power will increase

Explanation:

Power is the rate in which work is done or the rate of doing work

The formula for power is given as follows;

\(Power = \dfrac{Work \ done}{Time \ taken \ to \ do \ the \ work}\)

Therefore, power is directly proportional to work, and when work is increased provided all other factors remain constant, the power will be increased proportionately.

As such, for example, when the work is doubled, and the time to do the work is the same, the power has also doubled.

The geothermal gradient in the tectonically stable region is approximately 21°C/km, indicating that the temperature increases by an average of 21 degrees Celsius per kilometer of depth.

To calculate the geothermal gradient, we need to find the rate at which the temperature increases with depth.

Temperature at the surface (T₁) = 14°C

Temperature at a depth of 5.0 km (T₂) = 119°C

Temperature difference = T₂ - T₁ = 119°C - 14°C = 105°C

Depth difference = 5.0 km - 0 km = 5.0 km

Geothermal gradient = Temperature difference / Depth difference

Geothermal gradient = 105°C / 5.0 km

Calculating this expression, we find:

Geothermal gradient ≈ 21°C/km

When light is either reflected or refracted, the quantity that does not change in either process is its speed. Therefore, option (d) is the correct answer, speed.

The change in direction of light wave when it hits a surface and bounces back is known as reflection. The reflected light ray moves off at the same angle to the surface (angle of incidence) as it strikes the surface. The angle of incidence is the angle at which the incoming ray strikes the surface, and the angle of reflection is the angle at which the light reflects off the surface.

The process by which light bends as it passes from one medium to another with different densities is known as refraction. It is due to a change in speed, which causes light to change direction. When light passes from a medium with a higher index of refraction to one with a lower index of refraction, it bends away from the normal.

Conversely, if light passes from a medium with a lower index of refraction to one with a higher index of refraction, it bends toward the normal.

The quantity that does not change in either process is speed. Regardless of the angle at which it is reflected or the substance through which it passes when it is refracted, light always travels at the same speed.

1. The direction of the magnetic field at the center of the loop is perpendicular to the plane of the loop and follows the right-hand rule.

The right-hand rule states that if you curl the fingers of your right hand in the direction of the current flow in a loop, your thumb will point in the direction of the magnetic field at the center of the loop. The magnetic field lines are circular and perpendicular to the plane of the loop.

2. The expression for the magnitude of the magnetic field at the center of the arc can be calculated using the formula for the magnetic field due to a circular loop of wire. The expression is given by: B = (μ₀ * I) / (2 * r), where B is the magnetic field, μ₀ is the permeability of free space, I is the current in the loop, and r is the radius of the arc.

The magnetic field at the center of the arc formed by the right-angle bend in the wire can be calculated using the formula for the magnetic field due to a circular loop of wire. The magnetic field strength is directly proportional to the current in the loop (I) and inversely proportional to the radius of the arc (r). The permeability of free space (μ₀) is a constant value. By plugging in the values of current and radius, the expression for the magnitude of the magnetic field at the center of the arc can be determined.

3. The force per unit length between two parallel wires carrying current can be calculated using the formula: F/L = (μ₀ * I₁ * I₂) / (2 * π * d), where F/L is the force per unit length, μ₀ is the permeability of free space, I₁ and I₂ are the currents in the wires, and d is the distance between the wires.

The force per unit length between two parallel wires carrying current can be calculated using the formula above. The force is directly proportional to the product of the currents in the wires (I₁ and I₂) and inversely proportional to the distance between the wires (d). The permeability of free space (μ₀) is a constant value.

4. The force between two parallel wires depends on the direction of the currents. If the currents are in the same direction, the force is repulsive, and if the currents are in opposite directions, the force is attractive.

The direction of the currents in the two parallel wires determines the direction of the magnetic fields around the wires. When the currents flow in the same direction, the magnetic fields around the wires interact and result in a repulsive force between the wires. When the currents flow in opposite directions, the magnetic fields interact differently and result in an attractive force between the wires.

5. To find the current in the other wire when two parallel wires separated by a distance carry a force per unit length, the formula can be rearranged to solve for the current in the second wire, I₂ = (F/L) * (2 * π * d) / (μ₀ * I₁), where I₂ is the current in the second wire, F/L is the force per unit length, d is the distance between the wires, μ₀ is the permeability of free space, and I₁ is the current in the first wire.

By rearranging the formula for the force per unit length between two parallel wires, the current in the second wire (I₂) can be calculated. The force per unit length (F/L), the distance between the wires (d), and the current in the first wire (I₁) are known quantities, and the permeability of free space (μ₀) is a constant value.

The false statement(s) regarding color indicators are: "A color indicator will always change color exactly at the equivalence point of the titration" and "A color indicator is most effective over a large pH range." Color indicators are indeed used in titrations to signal the completion or neutralization of an acid-base reaction, and they are typically weak acids or bases themselves. However, they don't always change color exactly at the equivalence point, and they are most effective over a narrow pH range.

Answer:

Current, I = 8 Amps

Explanation:

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

\( V = IR\)

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

Given the following data;

Resistance, R = 30 ohms

Voltage, V = 240V

To find the current;

\( I = \frac {V}{R} \)

\( I = \frac {240}{30} \)

Current, I = 8 Amps

Therefore, the current of the dryer is 8 Amperes.

A total moment of inertia of 0.0375 kg·m² as the turntable spins.

The total moment of inertia of the two hoops or rings on the turntable can be calculated using the formula I = MR². The moment of inertia of each hoop can be calculated separately and then added together to find the total moment of inertia.

For the smaller hoop, the moment of inertia would be I = (3.0 kg)(0.050 m)² = 0.0075 kg·m².

For the larger hoop, the moment of inertia would be I = (3.0 kg)(0.10 m)² = 0.030 kg·m².

Adding these two values together gives a total moment of inertia of 0.0375 kg·m² as the turntable spins.

It's important to note that the mass of the turntable is ignored in this calculation, as instructed in the question. Also, the term "moment" in this context refers to moment of inertia, which is a measure of an object's resistance to rotational motion.

Answer: 0.85 N

Explanation: We can solve this problem using the principles of buoyancy and Newton's laws.

First, we need to find the buoyant force acting on the metallic alloy block. The buoyant force is equal to the weight of the water displaced by the block, which can be calculated using the block's volume and the density of water:

V = m_block / ρ_block = 3.4 kg / 3700 kg/m³ = 0.0009189 m³

F_buoyant = ρ_water x g x V = 1000 kg/m³ x 9.8 m/s² x 0.0009189 m³ = 8.96 N

So the buoyant force acting on the metallic alloy block is 8.96 N.

Next, we can calculate the tension force in the spring scale attached to the block. Since the block is in static equilibrium, the tension force must be equal in magnitude and opposite in direction to the weight of the block plus the buoyant force:

Tension force = weight of block + buoyant force

Tension force = m_block x g + F_buoyant

Tension force = 3.4 kg x 9.8 m/s² + 8.96 N = 42.04 N

So the hanging scale reads 42.04 N.

Finally, we can find the reading of the lower scale. The lower scale measures the weight of the beaker and the water in it, minus the buoyant force acting on the beaker. The weight of the beaker and the water is:

weight of beaker + weight of water = m_beaker x g + m_water x g

weight of beaker + weight of water = 1.3 kg x 9.8 m/s² + 2.5 kg x 9.8 m/s² = 35.35 N

The buoyant force acting on the beaker can be calculated using the volume of water displaced by the beaker:

V = m_water / ρ_water = 2.5 kg / 1000 kg/m³ = 0.0025 m³

F_buoyant = ρ_water x g x V = 1000 kg/m³ x 9.8 m/s² x 0.0025 m³ = 24.5 N

So the reading of the lower scale is:

Reading of lower scale = weight of beaker + weight of water - buoyant force

Reading of lower scale = 35.35 N - 24.5 N = 10.85 N

Therefore, the lower scale reads 10.85 N.
