In the peak of summer, it hasn't rained in a week, and the plants are looking rough, so watering the plants for an hour is a good idea.

However, the next day, you come back to the garden, and the plants look in worse shape than they did previously, as if none of that water made it to the plant. Plants absorb water through their roots. The root system of a plant is responsible for drawing water and nutrients from the soil. A plant's root system must be able to absorb water quickly in order for the plant to grow and thrive. When the soil around the root system is dry, the roots will stop growing and will not be able to absorb water.

It may even start to die. Watering plants during the peak of summer is important because it will help keep the soil moist and prevent the roots from drying out. However, watering a plant too much can be harmful. If a plant is overwatered, the water may not be able to penetrate the soil and reach the roots. Instead, it may just sit on top of the soil, causing the roots to rot and die. This can cause the plant to wilt and die.To summarize, if the soil around the plant is too dry, the roots may not be able to absorb the water you gave them, causing the plant to look worse than before. Conversely, overwatering can also be harmful because the water may not be able to penetrate the soil and reach the roots, causing the roots to rot and die.

Answer:

According to Newton's third law of motion, the reaction force is equal to the action force.

Explanation:

Newton's third law of motion states that for every action there is an equal and opposite reaction. This means that if one object exerts a force on a second object, the second object exerts an equal force in the opposite direction. When Plate X pushes on Plate Y with the action force (Fx), Plate Y must push back with an equal force (Fy).

Therefore, the best explanation is that according to Newton's third law of motion, the reaction force is equal to the action force.

For every action, there has equal and opposite reaction - this statement best describes the action and reaction forces on the plates.

As a result of this interaction, there are two forces: one from plate X and one from plate Y. The third law of motion of Newton deals with these two forces, which are referred to as action and reaction forces. Newton's third law is officially expressed as follows: There is an equal and opposite reaction to every action.

The implication of the statement is that there are always two forces acting on the two interacting objects. The force acting on the first object is equal in size to the force acting on the second. The force acting on the first object is acting in the opposite direction to the force acting on the second object. Force pairs—equal and opposing action-reaction force pairs—always exist in pairs.

The resistance of a circuit that contains two 50.0 Ω resistors connected in series with a 12.0 V battery is 100 Ω. The resistance of the circuit is equal to the sum of the individual resistors when they are connected in series.

In this case, two 50.0 Ω resistors are connected in series, resulting in a total resistance of 100 Ω. Resistance can be defined as the obstruction that electricity faces when it travels through a conductor. The greater the resistance, the less current is allowed to flow through the circuit. The following equation is used to calculate resistance: R = V / IWhere R is resistance, V is voltage, and I is current.

Resistance can also be calculated using Ohm's Law if we know the values of voltage and current. When resistors are connected in series, the total resistance of the circuit is equal to the sum of the individual resistors. This is expressed by the following equation:RT = R1 + R2 + ... + RNWhere RT is the total resistance of the circuit, and R1, R2, and RN are the individual resistors.

now moving onto the second row, the seismic station is now 'b' , the p-wave arrival time is 09:21:27 AM, the s-wave arrival time will be 09:22:27 AM, the S-P interval (in seconds) is 60, the distance to epicenter is 632,

now moving onto the third row, the seismic station is 'c', the p-wave arrival time is 09:21:49 AM, the s-wave arrival time is 09:23:05 AM, the S-P interval is 76, and the distance to epicenter is 806

The electric field intensity 10 cm away from the wire is 22.5 kV/m. The total flux through a closed surface around the wire is 0.45 Nm²/C. The electric force acting on an electron 10 cm away from the wire is 2.97 x 10⁻¹⁷ N.

The electric field intensity at a distance r from an infinitely long wire with charge density λ is given by the formula E = λ/ (2πε₀r), where ε₀ is the electric constant (8.85 x 10⁻¹² Nm²/C²). Substituting the given values, we get

E = (5 x 10⁻⁶ C/m) / (2π x 8.85 x 10⁻¹² Nm²/C² x 0.1 m)

   = 22.5 kV/m.

The total flux through a closed surface around the wire is given by the formula Φ = q/ε₀, where q is the total charge enclosed by the surface. In this case, the charge enclosed by a cylindrical surface with radius 0.1 m and length 2 m is q = λ x length = (5 x 10⁻⁶ C/m) x 2 m = 1 x 10⁻⁵ C. Substituting this value and ε₀ into the formula, we get

Φ = (1 x 10⁻⁵C) / (8.85 x 10⁻¹² Nm²/C²)

   = 0.45 Nm²/C.

The electric force acting on an electron placed 10 cm away from the wire is given by the formula F = qE, where q is the charge of the electron (-1.6 x 10⁻¹⁹ C) and E is the electric field intensity at that point. Substituting the given values, we get F = (-1.6 x 10⁻¹⁹ C) x (22.5 x 10³ V/m) = 2.97 x 10⁻¹⁷ N. Since the electron has a negative charge, the force is attractive and directed towards the wire.

The force which counteracts the thrust force for the flight is known as the drag force, as it opposes the flow.

Drag is a force that opposes an object's relative motion to a fluid environment in the field of fluid dynamics. It may be among two liquid film (or surfaces) or in between a liquid and a flat wall. The drag force is influenced by velocity, as opposed to other resistive forces like dry contact, which are essentially independent of it.

When a flow is moving at low or high speed, the drag force is equal to the speed for low pressure and to the square of the velocity for high-speed flow. Although viscous friction is what ultimately causes drag, turbulent drag is unaffected by viscosity.

A force in physics is an input that has the power to change an object's motion. A mass-containing object's velocity can vary, or accelerate, as a result of a force. Intuitively, a push or a pull can also be used to describe forces.

Answer:

Her altitude as she crosses the bar, h₂ is approximately 6.1 m

Explanation:

The given parameters of the motion of the pole vaulter are;

The mass of the pole vaulter, m = 57 kg

The speed with which the pole vaulter is running, u = 11 m/s

The speed of the pole vaulter when she crosses the bar, v = 1.1 m/s

The acceleration due to gravity, g = 9.8 m/s²

From the total mechanical energy, M.E. equation, we have;

M.E. = P.E. + K.E.

Where;

P.E. = The potential energy of the motion = m·g·h

K.E. = The kinetic energy of the motion = 1/2·m·v²

By the principle of conservation of energy, we have;

The change (loss) in kinetic energy, ΔK.E. = The change (gain) in potential energy, ΔP.E.

ΔK.E. = 1/2·m·(v² - u²)

ΔP.E. = m·g·(h₂ - h₁)

Where;

h₁ = The ground level = 0 m

h₂ = The altitude with which she crosses the bar

∴ 1/2·m·(v² - u²) = m·g·(h₂ - h₁)

(h₂ - h₁) = (v² - u²)/(2·g) = (11² - 1.1²)/(2·9.8) = 6.11173469388

h₂ = 6.11173469388 + h₁ = 6.11173469388 + 0 = 6.11173469388

h₂ = 6.11173469388

If a force F is applied to a block to move it up a frictionless incline at a 30-degree angle, the force required to overcome the gravitational component acting on the block is given by \(F_cos(30)\), where F is the applied force.

When a block is placed on an inclined plane, the force of gravity can be divided into two components: one parallel to the incline and one perpendicular to it. The force parallel to the incline, also known as the gravitational component, is given by \(F_g = mgsin(30)\), where m is the mass of the block and g is the acceleration due to gravity.

To move the block up the incline, an external force F must be applied in the opposite direction of the gravitational component. Since the incline is frictionless, the force required to overcome the gravitational component is equal to the applied force F. However, since the applied force is not acting directly against gravity but at an angle of 30 degrees, only the component of the applied force parallel to the incline contributes to overcoming gravity. This component is given by \(F_cos(30)\).
