What is the name of the great white whale?

The equivalent resistance of the circuit is 0.67 ohms. The current through the circuit is 7.46 amps.

1/Req = 1/R1 + 1/R2 + 1/R3 + ...

In this case, we have three resistors connected in parallel, so:

1/Req = 1/R1 + 1/R2 + 1/R3

1/Req = 1/2.00 + 1/2.00 + 1/2.00

1/Req = 1.5

Req = 0.67 ohms

the equivalent resistance of the circuit is 0.67 ohms.

I = V/R

In this case, the voltage is 5V and the resistance is 0.67 ohms, so:

I = 5/0.67

I = 7.46 amps

Resistance is the measure of an object's ability to impede the flow of electric current through it. It is measured in ohms (Ω). Resistance is determined by the physical properties of an object, such as its dimensions, material, and temperature. When electric current flows through a conductor, it encounters resistance that slows down its flow. This resistance is caused by the collisions between electrons and the atoms in the conductor. The greater the number of collisions, the higher the resistance.

Resistance can be affected by changes in the physical properties of the conductor, such as length, cross-sectional area, or temperature. A longer or narrower conductor will have higher resistance, while a wider conductor will have lower resistance. The resistance of most materials increases with temperature. Understanding resistance is important for designing and operating electrical circuits. By controlling the resistance of a circuit, engineers can ensure that the correct amount of current flows to power the devices connected to it.

Answer:

\(2.8\; {\rm s}\).

Explanation:

The velocity of vehicle \(2\) relative to vehicle \(1\) is:

\(\begin{aligned}& \text{velocity of 2 relative to 1} \\ =\; & (\text{velocity of 2 relative to ground}) \\ &- (\text{velocity of 1 relative to ground}) \\ =\; & 33\; {\rm m\cdot s^{-1} - 28\; {\rm m\cdot s^{-1}} \\ =\; & 5\; {\rm m\cdot s^{-1}} && (\text{to the east})\end{aligned}\).

The displacement of vehicle \(2\) relative to vehicle \(1\) is currently \(0\; {\rm m}\). The rate at which this displacement increases is equal to the velocity of vehicle \(2\!\) relative to vehicle \(1\!\), which is \(5\; {\rm m\cdot s^{-1}}\).

Thus, it would take \((14 \; {\rm m}) / (5\; {\rm m\cdot s^{-1}}) = 2.8\; {\rm s}\) for this displacement to reach \(14\; {\rm m}\).

The first extrasolar planets were so surprising that they forced a change in our theory of planet formation because they were massive like Jupiter but very close to their host star.

Extrasolar planet, also known as exoplanet, any astronomical body located outside the solar system that orbits a star other than the Sun.

Historically, the majority of extrasolar planets discovered appear to have been massive planets orbiting extremely close to their host stars. Astronomers were surprised by these "hot Jupiters," because planetary evolution theories predicted that such large planets should form only at great distances from stars.

The slit width when The distance between the first and fifth minima of a single slit diffraction pattern is 0.35 mm with the screen 40 cm away from the slit, when light of wavelength 550 nm is used is 2.514mm.

Given the distance between the first and fifth minima of a single slit diffraction pattern is (s) = 0.35mm = 0.35 x 10-3m

Let m1 = 1 and m2 = 5 represent the minima

distance of screen from the slit (d) = 40cm = 0.4m

wavelength of light used (λ​) = 550nm = 550 x 10-9m

Let the slit width = a

We know that a = mλ/ sinθ

To know the angle we take the distance of screen from slit in vertical direction as Δy where Δy = 0.35mmThen

sinθ = Δy/d

Then a = mλ/ (Δy / d)

a =  (m2-m1) x λ x d/(Δy) = (5-1) x  550 x 10-9 x 0.4/0.35x10-3

a = 2.514mm

More length of a wire is a component that has a greater resistance as the current through it increases​.

The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions present in the wire as they pass through. The moving electrons can collide with the ions present in the metal.

The correct answer is option E.

To calculate the work done by the truck to cover a distance of 5.8 × \(10^4\)meters, we need to use the equation for work:

Work = Force × Distance

In this case, the force can be calculated using Newton's second law:

Force = mass × acceleration

Where:

Acceleration (a) = \(0.0083 meters/second^2\)

Distance (d) = 5.8 ×\(10^4\) meters

Mass (m) = 7,000 kilograms

First, let's calculate the force exerted by the truck:

Force = mass × acceleration = (7,000 kg) ×\((0.0083 meters/second^2)\)= 57.1 Newtons

Next, we can calculate the work done:

Work = Force × Distance = (57.1 N) × (5.8 × 10^4 meters) = 3.3158 × \(10^6\)joules

Average Velocity = 3.65 m/s

Explanation:

Average Velocity  \(=\frac{Total Displacement}{Total Time}\) \(=\frac{22.1-3.85}{5}=\frac{18.25}{5}=3.65\)

The average velocity of a ball that rolls from x=3.85m to x=22.1m in 5 seconds is -3.65 m/s.

Given the following values:

Initial position, x = 3.85 m

Final position, x'= 22.1 m

Initial time, t = 0 seconds

Final time, t'= 5 seconds

The average velocity can be computed from the ratio of change in displacement and time.

The average velocity is given as:

v = (x'-x)/(t'-t)

v = (22.1-3.85)/(5-0)

v = -3.65 m/s

The formula for magnetic flux (Φ) is given by

Φ = B × A × cos(θ)

Where B is the magnetic field strength, A is the area, and θ is the angle between the magnetic field and the surface normal.

Given:

B = 2.0 T (magnetic field strength)

d = 3.0 cm (diameter of the bottle opening)

First, we need to calculate the area of the bottle opening. Since the opening is circular, the area can be determined using the formula

The strength of the electric force depends on the amount of charge on each object and the distance between them. Electric force, also known as Coulombic force, is a fundamental force of nature that is responsible for the interaction between charged particles. It is a long-range force that can be either attractive or repulsive depending on the charges of the particles involved.

The electric force between stationary charged objects is a force that arises due to the presence of an electric charge. When two or more stationary charged objects are in close proximity to one another, the electric force between them will cause them to attract or repel one another depending on their charges. Like charges repel each other, while opposite charges attract each other. The electric force between two stationary charged objects can be calculated using Coulomb's Law. According to Coulomb's Law, the magnitude of the electric force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. Mathematically, the formula for Coulomb's Law is given as F = k * q1 * q2 / r^2, where F is the force, k is Coulomb's constant, q1 and q2 are the magnitudes of the charges, and r is the distance between the charges.

The length must be increased by 0.0099 m to correct the period of the clock to 2.00 s.

Given:

T₀ = 2s

Original time period, T = 1.99s

The time period of a pendulum is:

T = 2π √(L/g)

Let the length of the pendulum be L₀.

The time period is:

T₀ = 2π √(L₀/g)

(T₀/2π)2 = L₀/g

L₀ = g (T₀/2π)2

Let the real length of the pendulum be L.

T = 2π √(L/g)

(T/2π)2 = L/g

L = g (T/2π)2

Subtract both the lengths, and we get:

L₀ - L = g (T₀/2π)2 - g (T/2π)2

L₀ - L = 9.81 m/s2 ( (2.00s/2π)2 - (1.99s/2π)2 )

The maximum height the projectile can reach is approximately 108.4 meters. To determine the maximum height of a projectile, we can analyze its vertical motion.

To determine the maximum height of a projectile, we can analyze its vertical motion. Given the initial speed (82.12 m/s) and launch angle (40 degrees), we can split the initial velocity into horizontal and vertical components.

The vertical component of the initial velocity is given by V0y = V0 * sin(angle), where V0 is the initial speed and angle is the launch angle. Therefore, V0y = 82.12 m/s * sin(40 degrees) ≈ 52.74 m/s.

Next, we can calculate the time it takes for the projectile to reach its maximum height. Since the vertical motion is symmetrical, the time taken to reach the maximum height is equal to the time taken to return to the same height. The formula to calculate the time of flight is T = 2 * V0y / g, where g is the acceleration due to gravity (approximately 9.8 m/s^2). Thus, T = 2 * 52.74 m/s / 9.8 m/s^2 ≈ 10.74 seconds.

Finally, we can determine the maximum height using the formula Hmax = V0y^2 / (2 * g). Plugging in the values, we get Hmax = (52.74 m/s)^2 / (2 * 9.8 m/s^2) ≈ 108.4 meters.
