The net force on a crate sliding at an unchanging speed when pushed with a steady force of 75 n is zero.

The total of all forces exerted on an object is known as the net force. A mass can accelerate due to net force. A body is subject to another force whether it is at rest or in motion. When there are a lot of forces acting on a system, the term "net force" is employed.

The total force acting on an object is its net force. Newton's second law, which states that F = ma, where F represents the net force, can be used to compute the net force. The object's mass is given by m. Acceleration is a.

The vector sum of all forces acting on an object is known as the net force. As a result of the fact that a force is a vector and that two forces with identical magnitudes and opposing directions cancel each other out, the net force is the sum of all the forces, or put another way, the net force is the sum of all the forces.

Given:

Position vector r = 2i + 2j + 0k

Force vector F = √30i + 3j + 0k

To calculate the moment of the force, we need to find the cross product of the position vector and the force vector. The cross product is defined as follows:

r x F = (ry * Fz - rz * Fy)i + (rz * Fx - rx * Fz)j + (rx * Fy - ry * Fx)k

Substituting the given values:

r x F = (2 * 0 - 0 * 3)i + (0 * √30 - 2 * 0)j + (2 * 3 - 2 * √30)k

     = -6i + (6 - 2√30)k

The moment of the force is determined by the magnitude of the cross product, which can be calculated as follows:

|M| = √((-6)^2 + (6 - 2√30)^2)

    = √(36 + (36 - 24√30 + 120))

    = √(36 + 36 - 24√30 + 120)

    = √(192 - 24√30)

    = √24(8 - √30)

    = 2√6(2 - √30)

Therefore, the moment of the force about point O is 2√6(2 - √30) Nm.

To store 1.60 j of energy, the capacitor of 0.600 μf must be charged to a potential of 2.31 kV.

To find the potential needed to charge a 0.600 μF capacitor to store 1.60 J of energy, we can use the formula for the energy stored in a capacitor:

Energy (E) = (1/2) × Capacitance (C) × Voltage^2 (V²)

We are given the energy (E = 1.60 J) and the capacitance (C = 0.600 μF), and we need to find the voltage (V).

1. Rearrange the formula to solve for V:

V² = (2 × E) / C

2. Plug in the given values:
V² = (2 × 1.60 J) / (0.600 μF)

3. Calculate the result:
V² = 5.333... (rounded to the nearest thousandth)

4. Take the square root of both sides to find V:
V = √5.333...

5. Calculate the final value for V:
V = 2.31 kV (rounded to the nearest hundredth)

So, you should charge the 0.600 μF capacitor to a potential of 2.31 kV to store 1.60 J of energy.

The method that returns the length of an array is the `length` method. This method gives the length of an array, which is the number of components (or elements) in an array. The syntax for using this method is as follows: array.length.

The `length` method is a built-in method in Java, and it returns the size of the array. The length method provides the exact size of an array and is not restricted to any specific data type. The syntax for using this method is `array.length`. Using this method, we can check the size of an array, validate it, and also detect when it exceeds the maximum size. For example, if we have an array `int[] numbers = {2, 4, 6, 8, 10};`, then to get the length of the array, we simply write `int size = numbers.length;`. This would return 5 since there are 5 elements in the array. Similarly, if we have a string array `String[] fruits = {"apple", "banana", "orange"};`, then `int size = fruits.length;` would return 3 because there are 3 strings in the array. Therefore, the `length` method is a simple, built-in method in Java that provides the size of an array, and we can use it to check the size of an array, validate it, and detect when it exceeds the maximum size.

The speed at which waves travel depends on the medium through which they are moving. In general, waves travel fastest through solids, followed by liquids, and then gases. This is because the molecules in solids are tightly packed and can transmit the waves more efficiently. Therefore, in general, waves will travel the fastest through a medium that is solid rather than liquid or gas.

For example, seismic waves travel fastest through solid rock, which is why earthquakes can be detected hundreds of miles away from their epicenter. Similarly, sound waves travel faster through water than through air, which is why underwater creatures can communicate over long distances.

In terms of electromagnetic waves, such as light and radio waves, travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second. However, when passing through a medium such as water or glass, their speed is reduced due to interactions with the molecules in the medium.

Answer:

The period of a wave or an oscillating system is the time it takes for the system to complete one full cycle of its motion. In physics and engineering, the period of a wave is a fundamental concept used to describe the behavior of periodic signals and systems. The period can be used to calculate other parameters of the wave, such as its frequency, wavelength, and velocity.

In this case, the oscillator completes 30 cycles in 15 seconds, meaning it completes a cycle every 15 seconds / 30 cycles = 0.5 seconds. So the period of the oscillator is 0.5 seconds. The frequency of the oscillator can then be calculated as the reciprocal of its period, which is 1 / 0.5 seconds = 2 Hz.

In conclusion, the period of an oscillator is an important parameter that describes its behavior, and it is directly related to other parameters such as frequency, wavelength, and velocity.

The weight of a \(45 kg\) box is \(441.45 N\).

Weight refers to the measure of the force exerted on an object due to the gravitational pull of the Earth.

Given the mass of the box is \(m=45 kg\).

The weight of an object (\(W\)) can be found by multiplying the mass of the object (\(m\)) by the acceleration due to gravity (\(g\)).

So, \(W=mg\).

It is known that acceleration due to gravity, \(g=9.81 m/s^2\).

Hence, the weight of the box, \(W=(45kg)\times (9.81 m/s^2)\).

\(\Rightarrow W=441.45 (kg\cdot m/s^2)\\\Rightarrow W=441.45 N\)

Therefore, the weight of the box is \(441.45 N\).

Explanation:

The energy in the initial state i.e. when the rollercoaster is at the top is equal to the energy in the final state i.e. when it is at the bottom of the hill.

These states can be represented by means of the second equation.

\(E_{k1}+E_{p1}=E_{k2}\\160 + 2500 = E_{k2}\\E_{k2}=2660 [J]\)

Since the rollercoaster is located in the bottom of the hill where the potential energy level is zero, therefore there is only kinetic energy in the second state.

Electrons absorb energy from the flame and become excited Electrons absorb energy from the flame and become excited, which causes them to emit light.

Electrons absorb energy when they are excited from their ground state. This phenomenon is commonly observed in the study of atomic and molecular spectroscopy. When energy is absorbed by an atom or molecule, the electrons are pushed into an excited state with higher energy levels.

The amount of energy absorbed corresponds to the difference between the ground state and the excited state of the electrons. This absorbed energy can come in various forms, such as electromagnetic radiation or collisions with other particles. Once the electron is in an excited state, it can release the absorbed energy as light or heat, or it can be involved in chemical processes like bonding or reaction.
