= 100²(sin30°)²/10

= 10000(0.25)/10

= 1000(0.25)

= 250m

height(max)= 250m

(ii)time it takes to reach the height= using π°/g

= 100sin30°/10

= 10 × 0.5

= 5

t= 5s

(iii)time of flight, T= 2t

T= 2(5)= 10

T= 10s

(iv)horizontal distance=H= u²cosπ°/2g

It will take the time  to drain completely in minutes when The density of water conversion is 1000g/1L is 75.76 minutes.

To write a mass balance for this process, we need to consider the inflow of water into the tank and the outflow of water from the tank. The mass balance equation for this process can be written as follows:

dM/dt = Q_in - Q_out

where dM/dt is the rate of change of the mass of water in the tank over time, Q_in is the inflow of water into the tank, and Q_out is the outflow of water from the tank.

In this case, the inflow of water into the tank is 32 g/s, and the outflow of water from the tank is 10 g/s. The initial mass of water in the tank is 200L * 1000 g/L = 200,000 g, and the tank is half full, so the initial mass of water in the tank is 200,000 g/2 = 100,000 g.

Substituting these values into the mass balance equation, we get:

dM/dt = 32 g/s - 10 g/s = 22 g/s

To determine how long it will take the tank to drain completely, we can solve the mass balance equation for t. The mass of water in the tank at any time t is given by:

M(t) = M(0) + dM/dt * t

where M(0) is the initial mass of water in the tank and t is the time in seconds.

Substituting the values for M(0) and dM/dt, we get:

M(t) = 100,000 g + 22 g/s * t

To drain the tank completely, the mass of water in the tank must be zero, so we can set M(t) = 0 and solve for t:

0 = 100,000 g + 22 g/s * t

t = -100,000 g / 22 g/s

t = -4545.45 s

Since there are 60 seconds in a minute, the time it will take the tank to drain completely in minutes is t/60 = -4545.45 s / 60 s/min = 75.76 minutes.

Answer:

1. Unbalanced Force (If you increase force, the acceleration will increase)

2. Mass of Body (If you increase mass, the acceleration will decrease)

Explanation:

According to Newton's Second Law the acceleration produced in a body depends upon two variables. The law states that:

“When an unbalanced force is applied on a body then an acceleration is produced in it, in its own direction”

The magnitude of produced acceleration is directly proportional to the applied force and inversely proportional to the mass of body. Mathematically,

   a α F

and,    a α 1/m

where,

a = acceleration

F = Unbalanced Force

m = Mass of Body

So, the acceleration increases when the unbalanced force increase and vice versa.

And the acceleration decreases when the mass of body increase and vice versa.

combining above equations:

a α F/m

a = (Constant)F/m

here,

Constant = 1

therefore,

F = ma

The correct option provided is option C) 5.7 m/s^2

When the rope is holding the rock, the tension force in the rope opposes the weight of the rock and the net force acting on the rock is zero. When the rope breaks, the tension force becomes zero and the weight of the rock is the only force acting on it.

The weight of the rock can be resolved into two components, one parallel to the inclined plane and one perpendicular to it. The component parallel to the inclined plane will cause the rock to accelerate down the plane.

The magnitude of the component of the weight parallel to the inclined plane is given by Wsinθ, where W is the weight of the rock and θ is the angle of the inclined plane with respect to the horizontal.

a = (Wsinθ)/m

where m is the mass of the rock.

Substituting the values, we get:

a = (10 kg) * sin(30°)/10 kg = 5 m/s^2

Therefore, the magnitude of the acceleration of the rock down the inclined plane if the rope breaks is 5 m/s^2.

The closest option provided is option C) 5.7 m/s^2.

Moment of inertia, a quantitative measure of the rotational inertia of a body in physics. The resistance that a body exhibits to changing its rotational speed about its axis by the application of a torque (torque). Axes can be internal or external and can be fixed or unfixed. However, the moment of inertia (I) is always given about this axis and is defined as the sum of the products of the mass of each particle in a particular body multiplied by the square of its distance from the axis. In calculating the angular momentum of a rigid body, the moment of inertia is analogous to the mass of linear momentum. For linear momentum, the momentum p is equal to the mass m multiplied by the velocity v. For angular momentum, on the other hand, the angular momentum L is equal to the moment of inertia I multiplied by the angular velocity ω.

R₁ = 40 × 10

R₂ = 90 × 10

R₃ = 40 × 10

⇒Iₓₓ = I₂ + 2(I₁ + A₁y²)

Where, y = distance between centroid of rectangle 1 and whole figure

I₁ = I₃ = Moment of inertia of rectangle = 1

I₂ = Moment of inertia of rectangle 2

Also,

I₂ = 90(10)³/12

I₂ = 7500 mm⁴

I₁ = 10(40)³/12

I₁ = 53333.33 m⁴

⇒Iₓₓ = 7500 + 2(53333.33 + 400(25)²)

⇒Iₓₓ = 7500 + 510666.66

= 614166.67 mm⁴

We know,

I = A k²

Where, k = radius of gyration

A = 400 + 900 + 400

A = 1700 mm²

1. The frequency of a light wave with a wavelength of 569 nm is approximately 5.28 × 10^14 Hz.

2. The wavelength of an electromagnetic wave with a frequency of 312 MHz is approximately 959.68 meters.

3. The frequency of a wave with a wavelength of 82 dm is approximately 3.66 Hz. One mole of these photons will have an energy of approximately 1.81 × 10^(-18) J.

4. The visible light range of 400-700 nm corresponds to a range of 400-700 × 10^(-12) meters or 4000-7000 picometers. The color of light with the highest energy is violet, which has the shortest wavelength within the visible spectrum.

To solve the first problem, we can use the equation:

Speed of light = frequency × wavelength

Rearranging the equation to solve for frequency:

frequency = Speed of light / wavelength

The speed of light is approximately 3.00 × 10^8 meters per second. Substituting the wavelength of 569 nm (converted to meters by dividing by 10^9), we can calculate the frequency.

For the second problem, we can use the same equation to solve for wavelength:

wavelength = Speed of light / frequency

Given a frequency of 312 MHz (converted to Hz by multiplying by 10^6), we can calculate the wavelength.

The third problem follows the same principle. We convert the wavelength of 82 dm to meters by multiplying by 0.1. Then we use the equation to solve for frequency.

For the fourth problem, we convert the visible light range of 400-700 nm to picometers by multiplying by 10^12. The color of light with the highest energy is violet because it has the shortest wavelength within the visible spectrum.

Answer:

as explained that poles have more gravitational

force (9.83m/s^2) as the poles of earth is nearer to the center because it is flat at poles

but certainly at equator is having less gravitational force (9.78m/s^2) as it is Farr from centre of earth because it is bulgded at equator.

In a circuit, it is assumed that the current flows from the negative terminal of a battery to the positive terminal. This means that point A would be connected to the negative battery terminal.

To understand why point A is connected to the negative terminal, we need to look at how a circuit works. A circuit is a closed loop through which electricity can flow. When a battery is connected to a circuit, it creates a potential difference, or voltage, which causes the electric charges to move.

In the case of a battery, the positive terminal has a higher potential energy than the negative terminal. This creates an electric field that pushes the electrons, which carry the current, from the negative terminal to the positive terminal.

So, when we say that the current flows from the negative terminal to the positive terminal, we mean that the electrons are moving in that direction. This convention was established by Benjamin Franklin, who originally thought that the current flowed from positive to negative.

In conclusion, point A in a circuit would be connected to the negative battery terminal because the current flows from the negative terminal to the positive terminal. This convention helps us understand the direction of electron flow in a circuit.

The frequency of the G allele in the population is 0.4, the correct option is B. 0.4.

The frequency of beetles with glabrous elytra in a population of ground beetles is 0.36. The frequency of the G allele is to be calculated, assuming that the population is in Hardy-Weinberg equilibrium.

What is Hardy-Weinberg equilibrium? The Hardy-Weinberg equilibrium is a model that describes the genetic makeup of a non-evolving population.

This model postulates that the genetic variation in a population remains constant from generation to generation in the absence of disturbing influences such as mutation, migration, or natural selection.

According to the Hardy-Weinberg equilibrium, the frequency of alleles and genotypes remains constant if certain conditions are met.

The Hardy-Weinberg equilibrium is represented by the following equation:p2 + 2pq + q2 = 1 Where:p2 = frequency of homozygous individuals (GG)2pq = frequency of heterozygous individuals (Gg)q2 = frequency of homozygous recessive individuals (gg)p + q = 1Now let's move on to the calculation of the frequency of the G allele.

The frequency of individuals with the gg genotype can be obtained from the following equation:q2 = 0.36q2 = 0.36^(1/2)q = 0.6

The sum of the frequency of all genotypes must be equal to 1, which can be used to calculate the frequency of the G allele:p + q = 1p = 1 - qp = 1 - 0.6p = 0.4The frequency of the G allele in the population is 0.4.Therefore, the correct option is B. 0.4.

A defibrillator is a medical device used to deliver an electric shock to the heart in order to restore normal heart rhythm during a life-threatening condition called cardiac arrest. The power delivered by a defibrillator is typically expressed in terms of energy rather than power.

The defibrillator delivers a high-energy electric shock, measured in joules (J), to the body. The energy delivered during defibrillation is used to depolarize the heart muscles and allow the natural pacemaker of the heart to resume control over the heart rhythm.

The energy delivered by a defibrillator can vary depending on the specific device and the protocol being followed. Typically, the initial shock delivered by a defibrillator ranges from 120 to 200 joules. However, subsequent shocks may require higher energy levels.

It's important to note that the power of the defibrillator is determined by the rate at which energy is delivered. Power is the rate of energy transfer, measured in watts (W). The power delivered by a defibrillator is typically very high for a very short duration, allowing for the rapid delivery of the required energy to the heart.

Overall, while the defibrillator delivers a high-energy electric shock measured in joules, the power of the device depends on the rate at which the energy is delivered, and it is typically very high for a very short duration.
