The electric potential difference between two parallel plates with an electric field strength of 875 N/C and separated by 0.002 m is 1.75 volts.

The question asks about the electric potential difference between two parallel plates given the electric field magnitude. To find the electric potential difference (V) between the plates, we use the equation V = E × d, where E is the electric field strength and d is the distance between the plates.

In this case, the electric field (E) is 875 N/C, and the distance (d) is 0.002 m. Therefore, the electric potential difference is:

V = E × d = 875 N/C × 0.002 m = 1.75 V

The electric potential difference between the plates is 1.75 volts.

Answer: gaseous

Explanation:

The major states of matter are solid, gaseous, liquid and plasma. However, there numerous others continued to be discovered such as Bose-Einstein condensate due to continuous research.

Solid state of matter usually have shape and volume which is a major physical characteristic of solids, liquid state of matter do not have shape but have volume however, the tend to occupy the shape of the container with respect to their volume in the container. Gaseous state of matter do not shape or volume but just occupy space in the container.

In a closed circuit there is a battery and resistor, from ohm's law if the voltage in the battery increases then the current in the resistor will also increase.

The connection between current, voltage, and resistance is described by Ohm's law. The voltage or potential difference across numerous materials determines how much constant current flows through them. As a result, if the voltage V (measured in volts) across two ends of a wire made of one of these substances is tripled, the current I (measured in amps) also triples, and the ratio V/I stay the same.

The resistance, R, for a specific material is it's V/I ratio and is expressed in ohms. Over extremely wide voltage and current ranges, the resistance of substances for which Ohm's law is applicable remains constant. The mathematical model for Ohm's law is V/I = R.

Therefore, from the formula of ohm's law if the voltage in the circuit will increase then the current will also going to increase with it.

The couch will move in the direction of the larger force being applied, which is the side of the person pushing with a force of 4 N.

When two people push a couch from opposite sides with forces of 2 N and 4 N respectively, the couch will move in the direction of the larger force. In this instance, the person applying the 4 N force will cause the couch to move in their direction, assuming no other forces are at play (like friction from the floor or additional forces from other directions). The movement can be predicted using Newton's Second Law of Motion, which states that the acceleration of an object is directly proportional to the net force acting upon it and inversely proportional to its mass.

Answer:

1 hectopascal = 100 Pascal

Explanation:

Pressure exerted by an object is defined as the force acting on it per unit area. Mathematically, it is given by :

[tex]pressure=\dfrac{force}{area}[/tex]

The SI unit of  unit of pressure is pascal. It is equivalent to :

[tex]1\ Pa=N/m^2[/tex]

or

[tex]1\ Pa=kg\ m^{-1}s^{-2}[/tex]

1 hectopascal = 100 Pascal

So, one hectopascal equals 100 pa. Hence, the correct option is (c).

The best metric is a combination of volume, frequency, soil moisture, evapotranspiration rate, and plant growth and health observation.

When measuring the amount of water given to a plant, it's crucial to choose a metric that accurately reflects the plant's needs and ensures optimal growth. The best metric to use for this purpose is:

1. **Volume of Water**: Measure water in milliliters or liters to quantify the actual amount provided to the plant.

2. **Frequency**: Track how often water is given, whether daily, weekly, or based on the plant's specific requirements.

3. **Moisture Content**: Use a soil moisture meter to gauge the water content in the soil around the plant's roots.

4. **Evapotranspiration Rate**: Consider the rate at which water evaporates from the soil and is transpired by the plant. This can help determine the water loss and replenishment needed.

5. **Plant Growth and Health**: Ultimately, the best measure is the plant's response. Monitor its growth, foliage appearance, and overall health to adjust watering practices accordingly.

By combining these metrics, you can ensure the plant receives the appropriate amount of water for optimal growth and health.

The balloon when touched with the wall sticks to it because of force of attraction between balloon and wall. the wall must have the charge opposite to what the balloon has on it. we know that unlike charge attract hence the balloon sticks to the wall.

Final answer:

The most suitable sensor for analyzing signals from outer space is radio wave sensors due to their economical production cost and efficiency in transmitting through interstellar space and atmospheres, thus providing valuable information about the sources of the waves.

Explanation:

In analyzing signals from outer space, the best sensor to use among sound waves, radio waves, and seismic waves would be radio wave sensors. Radio waves are the lowest-frequency and lowest-energy band of the electromagnetic spectrum, making them not only inexpensive to produce but also adept at traveling through interstellar dust, gas, and planetary atmospheres without significant absorption.

This capability is crucial for receiving unimpeded signals from space. The information collected through radio waves can reveal the chemistry and physical conditions of their sources. Moreover, radio waves are already extensively used in various communication systems on Earth. Therefore, in the context of SETI (Search for Extraterrestrial Intelligence) or any other form of cosmic study, radio waves are the most suitable and effective for gathering data from outer space.

Based on the linear expansion of iron, the increase in area is 0.15cm²

Linear expansivity is the increase in length per unit length of a material for every degree rise in temperature.

The linear expansion of iron is α = 1 × 10⁻⁵/°C

Length edge of the iron cube is 5cm

the surface area of cube A = 6L²

Initial surface area = 6 * 5² = 150cm²

The edge length of cube, L₂ after being heated from

10°C to 60°C is calculated using the formula below:

where

dt = 60-10 = 50°C

L₂ = 5(1 + 1 × 10⁻⁵ * 50)

Explanation: Animals do contribute to natural erosion. Plants help in keeping the soil at place. Some animals burrow the soil to live and helps in moving of soil from one place to another( process called soil erosion). Some animals leads to rapid destruction of plants and leads to faster erosion of soil as plants helps to keep soil at place. Lesser the number of plants will lead to more soil erosion.

Explanation:

It is given that the atom has 7 protons this means that atomic number of the atom is 7.

As we know that atomic mass of an atom is the sum of total number of protons and neutrons present in the atom.

So,       atomic mass of the given atom = no. of protons + no. of neutrons

                                                                = 7 + 7

                                                                 = 14

Thus, we can conclude that the mass of given atom is 14 g/mol.  

The mass of an atom with seven protons, seven neutrons, and eight electrons is 14 g

Given the following information from the question

Number of protons = 7 protons

Number of neutrons = 7 neutrons

Number of electrons = 8 electrons

The mass number of an atom is the sum of its atomic number and neutron number.

Mass number = number of neutron + atomic number

Since the atomic number of an element is equal to the number of protons of such elements, hence;

Mass number = 7 + 7

Mass number = 14 g

Hence the mass of an atom with seven protons, seven neutrons, and eight electrons is 14 g

Answer:

A the first law

B the second law

C the third law

Explanation:

All three Newton laws are involved in this example. Let's see why:

1) First Law: "an object which has a zero net force acting on it stays at rest if it was at rest or continue to move at constant speed if it was already moving" --> this law applies to the first part of the problem, before the launch, when the rocket is not moving: since no forces are acting on it, it stays at rest.

2) Second law: "a net force F applied to an object of mass produces an acceleration a given by the relationship:

[tex]F=ma[/tex]"

This law applies when the rockets starts its motion: in fact, a force of 44 N is applied to the rocket of mass 2.9 kg, and its acceleration is a=15.3 m/s^2, and we see that these numbers satisfy the previous equation.

3) Third law: "when an object A exerts a force on object B, object B exerts an equal and opposite force on object A"

This law applies when the rocket is in motion: in fact, the rocket pushes the hot gases outside, so the hot gases pushes back on the rocket, accelerating it so it moves forward.
