If a car moves with a uniform speed of 2m/s in a circle of radius 0.4m, what is its angular speed?

Answer:

The y-axis should be labelled as W in Newtons (kg·m/s²)

Explanation:

The given data is presented here as follows;

Mass (kg)            [tex]{}[/tex]        Newtons (kg·m/s²)

3.2                      [tex]{}[/tex]           31.381

4.6             [tex]{}[/tex]                    45.1111

6.1              [tex]{}[/tex]                    59.821

7.4              [tex]{}[/tex]                    72.569

9                [tex]{}[/tex]                     89.241

10.4              [tex]{}[/tex]                   101.989

10.9              [tex]{}[/tex]                  106.892

From the table, it can be seen that there is a nearly linear relationship between the  amount of Newtons and the  mass, as the slope of the data has a relatively constant slope

Therefore, the data can be said to be a function of Weight in Newtons to the mass in kilograms such that the weight depends on the mass as follows;

W(m) in Newtons = Mass, m in kg × g

Where;

g is the constant of proportionality

Therefore, the y-axis component which is the dependent variable is the function, W(m) = Weight of the body while the x-axis component which is the independent variable is the mass. m

The graph of the data is created with Microsoft Excel give the slope which is the constant of proportionality, g = 9.8379, which is the acceleration due to gravity g ≈ 9.8 m/s²

We therefore label the y-axis as W in Newtons (kg·m/s²)

The question is incomplete, the complete question is;

The ionization energy of an atom is the energy required to remove an electron from the atom. In the Bohr model, the ionization energy equals the energy difference between the lowest energy level n = 1 , In which the electron is closest to the nucleus, and the energy level n oo, which has an infinite radius. Compared to the ionization energy of hydrogen, the energy required to remove the electron from singly ionized helium is O two times greater. O four times greater. eight times greater. O one-half as great. O one-fourth as great.

Answer:

four times greater

Explanation:

For a hydrogen atom, an ionization energy of 13.6 electron volts is required to eject its single electron from the lowest energy level all the way out of the atom.

The helium ground state contains only two 1s electrons. When one of these is removed, He^+ looks quite similar to H^+.

The energy required to remove the remaining helium electron should be; 4×(13.6eV)=54.4eV since the energy depends on the square of the nuclear charge.

The answer is B.) Motion.

- Chilio

Answer:

2 and 0.6 ohms = 1.8A

4ohms = 1.08A

6 ohms = 0.72 ohms

Explanation:

With the help of the given diagram calculate the current through each resistor.​

According to ohms law

E = IRt

E is the electromotive force = 9V

I is the total current in the circuit

Rt is the total equivalent resistance

Get Rt

1/R = (1/4+1/6)  (parallel resistors)

1/R = 3+2/12

1/R = 5/12

R = 12/5

R = 2.4 ohms

Rt = 2 + 0.6 + 2.4

Rt = 5 ohms

Get the total current

I = E/Rt

I = 9/5

I = 1.8A

Since same current flows in a series connected resistors

Current in the 2 and 0.6 ohms resistors will be 1.8A

For the 4 and 6 ohms resistor:

Voltage across them is expressed as:

V = IR

V = 1.8(2.4)

V = 4.32Volts

The current in 4 ohms resistor

I = 4.32/4

I = 1.08A

The current in 6 ohms resistor

I = 4.32/6

I = 0.72A

Answer:

wet farts, JK its condensation.

Answer: Acceleration

Answer:

Explanation: CONVERT km/h TO m/s

WE GET 16.67 M/S

THEN,

USE : speed= distance / time

          16.67 = x / 3000

           ∴x = 50,000 m

or

           ∴x = 50 km
