What is the SI unit of length 6 Mcq?.

1 Nm (Newton-meter) is a unit of torque, which is a measure of the twisting force applied to an object, such as a shaft or a nut.

It is defined as the amount of force required to rotate an object around an axis by one radian (about 57.3 degrees). In other words, one Nm of torque is equal to the force of one Newton (N) acting at a distance of one meter (m) from the axis of rotation. It is a common unit of torque used in the field of mechanics and engineering, particularly in the design and operation of machines and vehicles. Torque is also related to the angular velocity of an object, and the rotational energy, which is calculated by multiplying the torque by the angle through which the object rotates. In a mechanical system, torque is often controlled by adjusting the position of the mechanical load or by applying a force to a lever to generate torque.

The three points like 2i +3j - 4k, 1i - 2j + 3k, and - 7j + 10k are collinear in terms of their position vectors.

If three or more points fall along a single straight line, they are said to be collinear. An axis is a term used to describe a line on which points are located, particularly if that line is connected to a triangle or other geometric shape. Since two points determine a line, two points are trivially collinear.

It is not always possible for the three spots to coincide. This indicates that depending on where these points are located in a plane, they may be collinear or noncollinear. If the slope between any two pairs of points is equal, three points are said to be collinear.

Three pairs of points can be created from the three points R, S, and T.

Assume A=2i+3j-4k.

B=i-2j+3k

C=-7j+10k

AB's current position vector is (i-2j+3k) - (i+3j-4k).

= -i-5j+7k

Now, BC's p.v. equals (-7j+10k) minus (i-2j+3k).

= -i-5j+7k

The p.v. of AB and BC are same. Therefore, the points are parallel and collinear.

Mass depends on several factors, including the force of gravity, the density of the object, and the volume of the object.

The force of gravity affects the mass of an object by determining the amount of force that acts on it. A greater gravitational force will result in a greater mass. The density of an object will also affect its mass; an object with a higher density will have a greater mass than an object with a lower density.

Finally, the volume of an object will also affect its mass; a larger object will have a greater mass than a smaller object. All three of these factors must be considered when determining the mass of an object.

Through ATP synthase, the hydrogen ions return down the gradient of their concentration. This causes the subunits to spin and generates the energy required for the fusion of ADP and inorganic phosphate to produce ATP.

In order to move hydrogen ions from the matrix into the intermembrane gap via the mitochondrial inner membrane during electron transport, energy is required. Through the action of ATP synthase, hydrogen ions move back across the mitochondrial membrane and into the matrix as a result of a chemiosmotic gradient, producing ATP.

A H+ accumulation occurs in the inner membrane space of the mitochondria as a result of the electrons from NADH and FADH2 moving through the electron transport chain.

Answer: You can not see it!

Explanation:

Newton's first law states that an object will continue to move unless a force acts on it. The second law states that force equals mass times acceleration.

Newton's first law, also known as the law of inertia, states that a body at rest will remain at rest and a body in motion will continue to move at a constant speed unless acted upon by an external force. I'm here. This means that the object will maintain its current state of motion unless a net force acts on it.

Newton's Second Law, also known as the Law of Acceleration or the Law of Force, states that the acceleration of a body is directly proportional to the net force acting on it and inversely proportional to its mass. This means that the force on an object is equal to its mass multiplied by its acceleration.

Newton's Third Law, also known as the "Law of Action and Reaction" or "The Law of Reciprocity", states that for all actions there are equal and opposite reactions. This means that when one object exerts a force on her second object, the second object exerts an equal and opposite force on the first object.

An active pendulum has the most kinetic energy at the bottom of its swing when the weight moves fastest. An ideal pendulum system always contains a steady amount of mechanical energy, the sum of kinetic and potential energy.

When the pendulum swings, it moves back and forth between its equilibrium or rest positions. The pendulum has kinetic energy except at the tipping point of the system where the pendulum velocity is zero. Pendulums also have potential energy associated with their height from the equilibrium position.

Answer:  A big Yes

Explanation: Viscosity depends strongly on temperature. In liquids, it usually decreases with increasing temperature, whereas, in most gases, Viscosity increases with increasing temperature.

As temperature increases, the average kinetic energy of the molecules also increases; it more easily overcomes the attractive forces between molecules. Therefore, Viscosity decreases with increasing temperature.

For example, when syrup is cold it has a high viscosity and can be difficult to pour. When heated in a microwave, the viscosity decreases and the syrup flows more freely. Similarly, Honey and oil tend to flow better at higher temperatures.

Both cohesion and molecular interchange contribute to liquid viscosity.  With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same.

When a liquid is heated, the kinetic energy of its molecules increases and the intermolecular attraction becomes weaker. Hence, the viscosity of a liquid decreases with an increase in its temperature.

The specific heat capacity of the metal is 0.17 J/g*C.

To determine the specific heat capacity of the metal, we can use the formula:

Q = mcΔT

Where Q is the heat absorbed or released, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature.

We know that the heat absorbed by the metal is equal to the heat lost by the water:

Qmetal = Qwater

We know the mass of the water, the initial and final temperature of the water, and the mass of the metal and the initial and final temperature of the metal. We can use this information to calculate the heat absorbed by the water and the heat absorbed by the metal.

Qwater = mwater * cwater * ΔTwater

Qmetal = mmetal * cmetal * ΔTmetal

We know that the heat absorbed by the metal is equal to the heat lost by the water, so we can set the two equations equal to each other:

mwater * cwater * ΔTwater = mmetal * cmetal * ΔTmetal

And we know that the specific heat of water is 4.18 J/g*C and the mass and the initial and final temperature of the water and the mass and the initial and final temperature of the metal

cmetal = mwater * cwater * ΔTwater / mmetal * ΔTmetal

cmetal = (140.0 g * 4.18 J/gC * (24.6 - 25.0)°C ) / (120.9 g * (24.6 - 100)) = 0.17 J/gC
