Resistance is a degree of competition to current drift in an electrical circuit. Resistance is measured in ohms, symbolized by way of the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the connection between voltage, modern, and resistance.

Given,

The resistance of the resistor, R=5 ω

The internal resistance of the battery, r=3ω

A rigid assembly consists of three identical uniform bars with an extra mass attached to one of them and the system's angular momentum is zero between locations A and B.

The rigid assembly conserves angular momentum because it can freely spin in the vertical plane about the point connecting the bars. Unless an external tension is applied, angular momentum, a vector quantity, is conserved.

The assembly's initial angular momentum is zero when it is in position A of rest since its linear momentum and distance from the axis of rotation are also zero.

Because there is no external torque operating on the system, when the extra mass experiences very little disturbance and the assembly moves to position B, its angular momentum stays constant.

As a result, the system's angular momentum is zero between locations A and B.

Acceleration was the last mathematical concept covered in Lesson 1. Acceleration is a frequently misunderstood concept that means something very different from what sports announcers or other people usually mean when they use it. Acceleration is described as follows: The rate that an object keeps changing its velocity is known as acceleration, a vector quantity. If an object's velocity is changing, it is accelerating. Sometimes when a person is moving quickly, sports announcers will say that the person is accelerating. But speed has nothing to with acceleration. Even when moving very quickly, a person may not be accelerating. Changing the speed at which an object is moving is what acceleration is all about.

The wave source must be coherent. That is, they emit identical waves with a constant phase difference.

Waves should be monochromatic - they should have a single wavelength. Suppose we have two sources emitting the same wave in phase. Whether constructive or destructive interference occurs at points close to the source depends on the path length difference δ. This is the distance from the point to one source minus the distance from the point to the other source.

The sun and moon cause ocean currents in several ways. First, the sun's heat causes the ocean water to expand and become less dense, which creates a rise in sea level. This rise in sea level creates a current that flows away from the equator and towards the poles.

Second, the moon's gravitational pull causes the oceans to bulge, creating tidal currents. These tidal currents can be very strong, and they cause the water to flow in circular patterns around the coasts.

Third, the moon's gravitational pull also causes the earth to rotate on its axis. This rotation creates a current called the Coriolis effect, which causes the ocean water to move in a circular pattern around the earth. This current helps to distribute heat and nutrients throughout the oceans.

Overall, the sun and moon cause ocean currents through their effects on sea level, tidal forces, and the earth's rotation.

Answer:

The sun warms up parts of the oceans. Warm waters rise just like warm air rises. So, as the warmer ocean waters begin to rise in a particular area, the cooler ocean waters from a different area will move in to replace the warmer ocean waters, and this creates our ocean currents.

1) The extension of the spring is 0.12 m

2) The distance is missing thus the gravitational potential energy can not be determined

3) The potential energy is given by 0.27 J

4) The energy that is missing is lost to friction.

According to the Hooke's law, the force that is exerted by an object on a spring is proportional to the extension as long as the elastic limit is not exceeded.

1) We have the following from the question and these would be used to solve the question.

K = force constant

e = extension

e = F/K

e = 4.36 N/37.5 N/m

e = 0.12 m

This is the distance between consecutive corresponding points of the same phase in the wave. A crest, trough, or zero-crossing of two adjacent waves, characteristic of both traveling and standing waves, and other spatial wave patterns. The reciprocal of wavelength is called spatial frequency. Wavelength is usually represented by the Greek letter lambda (λ). The term wavelength is also sometimes applied to the sinusoidal envelope of modulated waves and waves formed by interference of modulated waves or multiple sinusoids.

Assuming a sine wave traveling with constant wave velocity, the wavelength is inversely proportional to the frequency of the wave. Higher frequency waves have shorter wavelengths and lower frequency waves have longer wavelengths.

What is equilibrium?

Equilibrium, in physics, the state of a system when neither the state of motion nor the state of internal energy tends to change over time. A simple mechanical body is in equilibrium when it experiences neither linear nor angular acceleration. This state will continue indefinitely unless disturbed by an external force. Equilibrium occurs for a single particle when the vector sum of all forces acting on the particle is zero. A rigid body (which by definition differs from a particle by its properties of extension) is in equilibrium when, in addition to the states listed above for particles, the vector sum of all torques acting on the body is equal to zero, Its state of rotational motion remains constant. An equilibrium is said to be stable when a small externally induced displacement from that state produces a force opposing the displacement tending to return the body or particle to the equilibrium state. Examples include weights suspended from springs or bricks placed on a flat surface. Equilibrium is unstable when small deviations produce forces that tend to increase the displacement.

The results for the two fluids are so different because of the differences in their thermal and physical properties. Water has a much higher thermal conductivity than air, so it can transfer heat more quickly from the sphere to the fluid. Water also has a much higher density than air, so it can exert a greater drag force on the sphere.

What is atmospheric pressure?
The pressure within Earth's atmosphere is referred to as atmospheric pressure or barometric pressure (just after barometer). The definition of the standard atmosphere, or atm, is 101,325 Pa (1,013.25 hPa), which is equal to 1013.25 millibars, 760 mm Hg, 29,9212 inches Hg, or 14.696 psi. The Earth's average sea atmospheric pressure is roughly equivalent with one atm, or one atmosphere, and is measured in the atm unit. In most cases, the hydrostatic pressure brought on by the weight of the air just above measurement point is a close approximation of atmospheric pressure. Because there is less atmospheric mass at lower elevations, atmospheric pressure decreases as elevation rises.

(a) Drag Force:
The drag force on a sphere in water can be calculated using the drag equation:

F _ d = 0.5 * C _ d * ρ_f * V ^ 2 *A

Where C _ d is the drag coefficient for a sphere, ρ _ f is the fluid density, V is the fluid velocity, and A is the projected area of the sphere.

For water, C _ d = 0.47, ρ _ f = 1000 kg/m3, V = 2.5 m/s and A = 314.16 mm2.

Therefore, the drag force on the sphere is:
F _ d = 0.5 * 0.47 * 1000 * 2.5 ^ 2 * 314.16 = 371.2 N

Heat Rate:
The rate of heat transfer from the sphere to the fluid can be calculated using the following equation:
Q _ dot = h * A * ( T _ s - T _ f )

Where h is the heat transfer coefficient, A is the surface area of the sphere, T _ s is the temperature of the sphere, and T _ f is the temperature of the fluid.
For water, h = 4500 W/m2K.
Therefore, the rate of heat transfer is:
Q _ dot = 4500 * 314.16 * (60 - 30) = 4.4 x 10 ^ 6 W

(b) Drag Force:
The drag force on a sphere in air can be calculated using the same equation as for water:
F _ d = 0.5 * C _ d * ρ _ f * V ^ 2 * A

Where C _ d is the drag coefficient for a sphere, ρ _ f is the fluid density, V is the fluid velocity, and A is the projected area of the sphere.
For air, C _ d = 0.47, ρ _ f = 1.2 kg/m3, V = 2.5 m/s, and A = 314.16 mm2.

Therefore, the drag force on the sphere is:
F _ d = 0.5 * 0.47 * 1.2 * 2.5 ^ 2 * 314.16 = 31.2 N

Heat Rate:
The rate of heat transfer from the sphere to the fluid can be calculated using the same equation as for water:
Q _ dot = h * A *(T _ s - T _ f)

Where h is the heat transfer coefficient, A is the surface area of the sphere, T _ s is the temperature of the sphere, and T _ f is the temperature of the fluid.
For air, h = 30 W/m2K.

Therefore, the rate of heat transfer is:
