Answer:

The trains will collide at a distance 1660 m from the station

Explanation:

Let the train traveling due north with a constant speed of 100 m/s be Train A.

Let the train traveling due south with a constant speed of 136 m/s be Train B.

From the question, Train B leaves a station 2,881 m away (that is 2,881 m away from Train A position).

Hence, the two trains would have traveled a total distance of 2,881 m by the time they collide.

∴ If train A has covered a distance \(x\) m by the time of collision, then train B would have traveled \((2881 - x)\) m.

Also,

At the position where the trains will collide, the two trains must have traveled for equal time, t.

That is, At the point of collision,

\(t_{A} = t_{B}\)

\(t_{A}\) is the time spent by train A

\(t_{B}\) is the time spent by train B

From,

\(Velocity = \frac{Distance }{Time }\\\)

\(Time = \frac{Distance}{Velocity}\)

Since the time spent by the two trains is equal,

Then,

\(\frac{Distance_{A} }{Velocity_{A} } = \frac{Distance_{B} }{Velocity_{B} }\)

\({Distance_{A} = x\) m

\({Distance_{B} = 2881 - x\) m

\({Velocity_{A} = 100\) m/s

\({Velocity_{B} = 136\) m/s

Hence,

\(\frac{x}{100} = \frac{2881 - x}{136}\)

\(136(x) = 100(2881 - x)\\136x = 288100 - 100x\\136x + 100x = 288100\\236x = 288100\\x = \frac{288100}{236} \\x = 1220.76m\\\)

\(x\)≅ 1,221 m

This is the distance covered by train A by the time of collision.

Hence, Train B would have covered (2881 - 1221)m = 1660 m

Train B would have covered 1660 m by the time of collision

Since it is train B that leaves a station,

∴ The trains will collide at a distance 1660 m from the station.

In science, variables are factors or conditions that change or affect the outcome of a study. They can be classified into three types: independent variables, dependent variables, and controlled variables. Dependent variables are those that researchers measure to assess the impact of independent variables.

In science, variables are factors or conditions that change or affect the outcome of a study. They can be classified into three types: independent variables, dependent variables, and controlled variables. Identifying variables is critical in any research, as they enable scientists to control the study's conditions, determine cause-and-effect relationships, and achieve accurate results.
Independent variables are those that researchers manipulate to investigate their effect on the dependent variable. They are also called explanatory or predictor variables.

For instance, in a study investigating the effect of different levels of fertilizer on plant growth, the independent variable is the level of fertilizer.
Dependent variables are those that researchers measure to assess the impact of independent variables.

They are also called response variables. In the plant growth study, the dependent variable is the growth rate or size of the plants.
Controlled variables are those that researchers hold constant throughout the study to reduce the impact of extraneous factors on the outcome.

They are also called confounding or intervening variables. In the plant growth study, controlled variables include the type of plant, the amount of water, the light exposure, and the temperature.
In conclusion, identifying variables is crucial in scientific research to achieve accurate results, establish cause-and-effect relationships, and control the study's conditions. Independent, dependent, and controlled variables are the three types of variables used in scientific studies.

Torque:-

\(\\ \rm\Rrightarrow \tau=0.25Nm\)

option B

Answer:

False

Explanation: not even light can escape through the event horizon from the black hole. At its center, each black hole is thought to have a singularity, a point of infinite density, and zero volume.

False. In the process of beginning an action potential, the threshold refers to a minimum membrane potential that needs to be reached to initiate the action potential. It is not related to the intensity of excitatory minus inhibitory stimulation.

The threshold is a critical level of depolarization that must be achieved in the neuronal membrane for an action potential to be triggered. When the membrane potential reaches the threshold, voltage-gated sodium channels open, allowing an influx of sodium ions into the cell. This causes a rapid depolarization and the initiation of the action potential.

The concept of excitatory and inhibitory stimulation is related to the overall balance of synaptic inputs received by a neuron, which can influence the likelihood of reaching the threshold. Excitatory inputs increase the chances of reaching the threshold, while inhibitory inputs decrease the likelihood. However, the threshold itself is not dependent on the intensity of excitatory minus inhibitory stimulation, but rather on the membrane potential reaching a specific level.

The equation PE = mgh relates gravitational potential energy to mass, acceleration due to gravity, and height, gravitational potential energy itself is a distinct concept representing the energy associated with an object's position in a gravitational field.

According to the equation PE = mgh, gravitational potential energy (PE) is the product of mass (m), acceleration due to gravity (g), and height (h). However, gravitational potential energy is not the same thing as any of these individual quantities.

Gravitational potential energy refers to the energy possessed by an object due to its position in a gravitational field. It represents the potential for the object to do work when it is released and allowed to fall or move under the influence of gravity.

Mass (m) represents the amount of matter an object contains, acceleration due to gravity (g) represents the strength of the gravitational field, and height (h) represents the vertical distance from a reference point to the object. These quantities are used together in the equation to calculate the gravitational potential energy of the object.

An e-contract, must meet the same basic requirements (agreement, consideration, contractual capacity, and legality) as a paper contract.

In today's digital age, e-contracts have become increasingly common and serve as legally binding agreements between parties. Like traditional paper contracts, e-contracts require mutual agreement, where both parties express their intent to be bound by the terms of the contract. Consideration, or the exchange of something of value, must be present for the contract to be valid. Additionally, the parties entering into the e-contract must have the contractual capacity, meaning they are of legal age and mentally competent to understand the terms and obligations involved. Lastly, the e-contract must comply with the laws and regulations governing contracts, ensuring that the agreement's subject matter and purpose are lawful.

The amount of such tangential velocity corresponds to the ladybug's rotational motion's tangential velocity.

If an item moves uniformly and moves for time t, it will have angular momentum of magnitude v, which is given by v = s/t, where period of motion T is the duration that it takes for one rotation to complete (in seconds), while frequency f would be the number of rotations per second (units: s–1 or Hz).

The amount of distance covered in a given amount of time is known as linear speed, or simply speed. A point farther from the centre of a merry-go-round as well as turntable travels much greater distance inside one full circle.

Tangential speed is defined as the speed in a circular path that is equal to the speed of a motion on a straight line. Circular motion requires the presence of another force (tension, friction, or normal force) to create the centripetal acceleration.

4.67 x 10⁻¹⁹ J  is the energy in joules if the wavelength of light detected is 431 nm.

The energy of a photon can be calculated using Planck's constant (h) and the frequency (v) of the light:

E = h * v,

where v is the frequency of the light and h is Planck's constant (h = 6.626 x 10⁻³⁴ J s).

The frequency of light can be calculated from its wavelength (λ) using the equation:

v = c / λ,

where c is the speed of light in a vacuum (c = 299,792,458 m/s).

So, for a wavelength of 431 nm (431 x 10⁻⁹ m), the frequency is:

v = c / λ = 299,792,458 m/s / (431 x 10⁻⁹ m) = 6.95 x 10¹⁴ Hz.

And finally, the energy of the photon can be calculated as:

E = h * v = 6.626 x 10⁻³⁴ J s * 6.95 x 10¹⁴ Hz = 4.67 x 10⁻¹⁹ J.
