Hello, yes it is possible to lift heavier load using small magnitude of force.

How? let's see.

Do you know on which principle does hydraulic machine work? Yes, it's Pascal's Principle. So in order to understand how hydraulic machine will lift heavier weight using small magnitude of force we will have to take a look at Pascal's law.

Pascal's law : It sates that in a closed container filled with fluid when pressure is applied to any point that intensity of pressure transfers in all direction equally.

Now look at diagram,

Consider the left piston as X and Right Piston as Y.

the area of piston X is small (A1) and applied force (F1) is also less and the resultant pressure is P.

\(P = \frac{F_1}{A_1}\)

This same amount of pressure will be exerted at Piston Y having area (A2) and resultant output force (F2)

\(P = \frac{F_2}{A_2}\)

So consider I have 5 N force and I have to lift a heavier rock weighing 50 N. take an example the area of Piston X is 1 m² & area of piston Y is 10 m²

So when I will apply 5 N force on piston X it will exert 50 N force on piston Y.

The magnitude of the second force acting on the 24 kg mass in the positive x direction is 611 N.

To solve this problem, we need to use Newton's Second Law of Motion, which states that the net force acting on an object is equal to the product of its mass and acceleration. We are given the mass of the object (24 kg) and its acceleration (28 m/s in the positive x direction), and we need to determine the magnitude of the second force acting on it.

Let F₁ be the magnitude of the force acting in the negative y direction and F₂ be the magnitude of the second force acting on the object in the positive x direction. The net force acting on the object can be represented as the vector sum of these two forces:

F = √(F₁² + F₂²)

We know that F = m * a, where m is the mass of the object and a is its acceleration.

Substituting the given values, we get:

F = 24 kg * 28 m/s = 672 N

Squaring both sides and substituting F, we get:

F₁² + F₂² = (672 N)²

Substituting the value of F₁ (260 N) and solving for F₂, we get:

F₂ = √((672 N)² - (260 N)²) = 611 N

The distance of closest approach between the proton and the alpha particle is determined by their initial speeds and masses.

Since both particles have the same initial speed of 0.007c, their kinetic energies are equal. The total energy (kinetic + potential) of the system is conserved; therefore, the potential energy of the two particles is equal and opposite, and is determined by the product of their charges and the inverse of the distance between them.

The distance of closest approach is then determined by solving for the distance between the two particles that produces equal and opposite potential energy.

Using the equation of energy conservation, the distance of closest approach between the two particles is given by: d=(2q^2)/E, where q is the charge of the alpha particle, q=+2e, and E is the total energy of the system.

Substituting the values for q and E yields d=(2*2^2)/(2*0.007c^2*3.0x10^8 m/s^2)=0.00044m. Therefore, the distance of closest approach between the proton and the alpha particle is 0.00044m.

"The force that can cause an object to rotate along an axis is measured as torque." Similar to how force accelerates an object in linear kinematics, torque accelerates a body in an angular direction.

Torque is a measure of the turning effect of an applied force about a specific point or axis. It is computed by multiplying the force exerted on a body by the separation between the point of rotation and the application of the force.

The torque increases as the force or distance from the centre of rotation increases. The unit of torque is typically Newton-meters (N·m) in the International System of Units (SI) or pound-feet (lb·ft) in the imperial system. In several fields, including physics, mechanics, engineering, and robotics, torque is important.

If two forces produce equal impulses, but the second force acts for a time twice that of the first force, then the first force is larger than the second force.

If two forces produce equal impulses, then we can say that the magnitudes of the impulses are equal. The impulse is defined as the force multiplied by the time for which the force acts. Mathematically, we can represent it as:

Impulse = Force x Time

Let's assume that the first force is F1 and it acts for a time t1, while the second force is F2 and it acts for a time 2t1. Therefore, we can write:

Impulse1 = F1 x t1

Impulse2 = F2 x 2t1

Since both impulses are equal, we can equate them:

Impulse1 = Impulse2

F1 x t1 = F2 x 2t1

We can simplify this equation to:

F1 = 2F2

This means that the magnitude of the second force is smaller than the first force by a factor of 2. Therefore, the first force is larger than the second force.

The coefficient of static friction is greater than the coefficient of kinetic friction because it must overcome the initial inertia and intermolecular forces keeping surfaces at rest together, whereas kinetic friction deals with the resistance to motion once the surfaces are already moving.

When two surfaces are at rest relative to each other, the coefficient of static friction comes into play. This frictional force resists the tendency of the surfaces to start moving.

The coefficient of static friction is higher because it needs to overcome the initial inertia and intermolecular forces holding the surfaces together. The irregularities and interlocking between the surfaces require more force to break them apart and initiate motion.

The clock is moving at approximately 0.866 times the speed of light.

To solve this, we need to consider the concept of relativistic length contraction. According to the theory of relativity, when an object moves at a high speed relative to an observer, its length in the direction of motion appears contracted. Let's use the given terms to answer the question:

1. The rectangular clock has a width of 24 cm and a height of 12 cm at rest.
2. When the clock moves parallel to its width with a certain speed, it appears as a square to an observer.

A square has equal sides, so when the clock appears as a square, its contracted width (W') will be equal to its height (H) which is 12 cm. We can use the length contraction formula to find the speed at which the clock is moving:

W' = W * sqrt(1 - v^2/c^2)

Where W' is the contracted width (12 cm), W is the original width (24 cm), v is the speed we're trying to find, and c is the speed of light (~3 x 10^8 m/s).

Rearranging the formula to solve for v:

v^2/c^2 = 1 - (W'/W)^2

Now, let's plug in the given values and solve for v:

v^2/c^2 = 1 - (12/24)^2
v^2/c^2 = 1 - 0.25
v^2/c^2 = 0.75

v^2 = 0.75 * c^2
v = sqrt(0.75) * c

Since we're only looking for the relative speed, we can leave the answer in terms of c:

v ≈ 0.866 * c

So, the clock is moving at approximately 0.866 times the speed of light.

Darcy's Law expresses the rate of groundwater flow as a function of hydraulic conductivity, hydraulic gradient, and the cross-sectional area through which the water is flowing.

Darcy's Law provides a fundamental understanding of how groundwater moves through porous media like soil and rock. Hydraulic conductivity, typically denoted by 'K,' is a measure of the ease with which water can move through a porous medium, and it depends on both the material's properties and the fluid's viscosity.  The hydraulic gradient, represented by 'dh/dl,' is the change in hydraulic head (water pressure) over a given distance, which is what drives the flow of groundwater.

The cross-sectional area, 'A,' refers to the area through which the water flows. Darcy's Law is often written as Q = -KA (dh/dl), where 'Q' is the discharge or flow rate. This equation shows the relationship between the flow rate and these three variables, highlighting the factors that influence groundwater movement. By understanding and applying Darcy's Law, we can predict the behavior of groundwater and its impact on various environmental and engineering processes. So therefore Darcy's Law expresses the rate of groundwater flow as a function of hydraulic conductivity, hydraulic gradient, and the cross-sectional area through which the water is flowing.

To find the current in the resistor, we can use Ohm's Law and the concept of equivalent resistance. Thus, option A is correct.

First, let's calculate the equivalent resistance of the three cells connected in parallel. When resistors are connected in parallel, the reciprocal of the equivalent resistance is equal to the sum of the reciprocals of the individual resistances:

1/Req = 1/R1 + 1/R2 + 1/R3

Given that R1 = R2 = R3 = 22 Ω (internal resistance of each cell), we can substitute the values:

1/Req = 1/22 + 1/22 + 1/22

1/Req = 3/22

Taking the reciprocal of both sides, we find:

Req = 22/3 Ω

Now we can use Ohm's Law to calculate the current (I) in the resistor. Ohm's Law states that the current flowing through a resistor is equal to the voltage across it divided by its resistance:

I = V/R

Given that V = 1.1 V (emf of each cell) and R = 32 Ω (resistance), we can substitute the values:

I = 1.1/32

Calculating this value, we find:

I ≈ 0.034375 A
