A resistor carries 0.40 a when connected to a 9.0-v battery. what is theresistance of the resistor?

The average rate of disappearance of i - between 1200.0s and 1600.0s

is 2.0 × 10⁻⁵ m/s.

To determine the slope of a graphed function, use the average rate of change formula. Divide the change in y-values by the change in x-values to determine the average rate of change.

The rate of disappearance for reactants is a positive (+) value. Because products are being made rather than disappearing, their rate of disappearance (-) is negative.

The average rate of reaction = Change in concentration

Time rate ( r ) = Δx Δt.

Sign of average rate of reaction: The average rate falls as the rate of reactant concentration increases.

There will be a bad response. The average rate of reaction will be positive as the rate of product concentration rises.

The average rate of disappearance of i - between 1200.0s and 1600.0s

is 2.0 × 10⁻⁵ m/s.

Therefore, the correct answer is option C) 2.0 × 10⁻⁵

Proton is an elementary particle that is identical to the nucleus of the hydrogen atom, along with the neutron is a constituent of all other atomic nuclei, that carries a positive charge numerically equal to the charge of an electron, and has a mass of 1.673 × 10−27 kilogram

nonrelativistic equation for the magnitude of the momentum of the proton is p = m * v

Then: p = m * v

Then Let's calculate its value

            After that p = 1.67 * 10⁻²⁷ * 0.99 * 3 * 10⁸

            Now, p = 4.96 * 10⁻¹⁹ kg m / s

65 mi/h would be the relative velocity between you and the truck.

Speed is the directional speed of an item moving as a sign of its pace of progress ready as seen from a specific casing of reference and as estimated by a specific norm of time. Speed is a principal idea in kinematics, the part of traditional mechanics that depicts the movement of bodies. It could sound convoluted, yet speed is fundamentally speeding in a particular course. It is a vector amount, and that implies we want both extent (speed) and bearing to characterize speed. The SI unit of it is meter each second (ms-1 ). In the event that there is a shift in extent or the course in the speed of a body the body is supposed to speed up.

The stream has a mass flow rate of 1.666 g/sec and a volumetric flow rate of 1.666 ml/sec.

The dimensionless quantity mass is used to represent the amount of matter contained in a particle or object (symbolized m). The kilogram is the chosen unit of mass according to the International System (SI) (kg).

The following equation can be used to determine mass = volume * density. It is possible to gauge the gravitational force acting on a mass by determining its weight. The Newton (N) is the SI unit of weight (N).

t= 30 sec

V= 50ml

Volumetric flow rate = V/t

                                  = 50ml/30sec

                                  = 1.666 ml/sec

We know density of water= 1g/cm³

                                           = 1 g/ml

So, mass flow rate = V/t

                                = 1g/ml * 50ml/30sec

Answer:

The friction between the crate and the floor is the same amount as your pushing force when you push a crate across a level floor at constant velocity.

Explanation:

Remember that the force produced by two surfaces coming into contact and sliding against one another is frictional force. This is expressed by the direct relationship between frictional force and normal force.

f=μN

Where

f = frictional force

µ = coefficient of friction

N = Normal force

By dry friction, two solid surfaces in touch are opposed to one another's relative lateral motion. Dry friction is further separated into kinetic friction between moving surfaces and static friction (sometimes known as "stiction") between non-moving surfaces. Additionally, dry friction is typically caused by the interaction of surface characteristics, particularly rough surfaces.

[tex]LD(111) = 1.646 nm^{-1}[/tex]

Linear Density = No of atom centered on the direction vector / Length of direction vector.

[tex]LD(100) = \frac{1 atom}{2R\sqrt{2} }\\LD(111) = \frac{1 atom}{2R\sqrt{6} }[/tex]

[tex]R = 0.124 nm[/tex]

So, it becomes,

[tex]LD(100) = \frac{1}{2 * 0.124 \sqrt{2} } \\= > 2.851 nm^{-1}[/tex]

[tex]LD(111) = \frac{1}{2 * 0.124\sqrt{6} } \\ = > 1.646 nm^{-1}[/tex]

Hence, the linear density of iron 110 is 2.851nm⁻¹ and the linear density of iron 111 is 1.646nm⁻¹.

If a material has a non-uniform cross section, the linear mass density is a constant term that allows us to calculate the mass of the material at any given length between x = 0 and x = L. The cgs unit is g/cm whereas the SI unit for linear mass density is kg/m.
