How can three resistors of resistances 2 ohm 3 ohm and 6 ohm be connected to give a total resistance

Answers

Answer 1
Answer:

Explanation:

Three resistors of resistances 2ohm,3ohm, and 6ohm respectively.

Let R1=2Ω

⇒R2=3Ω

⇒R2=6Ω

● A total resistance of 4Ω from three resistors of given resistances. Firstly, connect the two resistors of 3Ω and 6Ω in parallel to get a total resistance of 2Ω which is less than the lowest individual resistance.

●When R 2 and R 3 are connected in parallel with

R1 in series we get

⇒1/R=1/R2+1/R3

⇒1/R=1/3+1/6

⇒1/R=1/2

⇒R=2Ω

Hence, the total resistance of the circuit is 4Ω.

What was the main effect of the Equal Employment Opportunity Act of 1972?A. It prohibited discrimination based on age.
B. It extended the provisions of the Pregnancy Discrimination Act.
C. It extended the provisions of Title VII to previously exempt
employers.
OD. It prohibited different wages for men and women performing the
same work.

Answers

The main effect of the Equal Employment Opportunity Act of 1972 was option C: It extended the provisions of Title VII to previously exempt employers. This act expanded the coverage of Title VII of the Civil Rights Act of 1964 to include state and local governments, public educational institutions, and some private and public employment agencies. It aimed to address and prohibit employment discrimination based on race, color, religion, sex, or national origin by a wider range of employers and entities.

Final answer:

The main effect of the Equal Employment Opportunity Act of 1972 was C. It extended the provisions of Title VII to previously exempt

employers.

Explanation:

The main effect of the Equal Employment Opportunity Act of 1972 (EEOA) was to extend the coverage of Title VII of the Civil Rights Act of 1964 to previously exempt employers. Before the EEOA, Title VII applied only to employers with 25 or more employees, leaving smaller employers unaffected. The EEOA expanded the reach of Title VII to include employers with 15 or more employees.

This significant change aimed to combat employment discrimination on the basis of race, color, religion, gender, or national origin more comprehensively by ensuring that a broader range of employers adhered to anti-discrimination measures.

Ann (mass 50 kg) is standing at the left end of a 15-m-long, 500 kg cart that has frictionless wheels and rolls on a frictionless track. Initially both Ann and the cart are at rest. Suddenly, Ann starts running along the cart at a speed of 5.0m/srelative to the cart.How far will Ann have run relative to the ground when she reaches the right end of the cart?
Express your answer with the appropriate units.

Answers

Answer:

13.5 m

Explanation:

M = Mass of cart = 500 kg

m = Ann's mass = 50 kg

v_m = Velocity of Ann relative to cart = 5 m/s

v_M = Velocity of Cart relative to Ann

As the linear momentum of the system is conserved

Mv_M+mv_m=0\n\Rightarrow v_M=-(mv_m)/(M)\n\Rightarrow v_M=-(50* 5)/(500)\n\Rightarrow v_M=-0.5\ m/s

Time taken to reach the right end by Ann

Time=(Distance)/(Speed)\n\Rightarrow Time=(15)/(5)=3\ s

Distance the cart will move in the 3 seconds

Distance=Speed* Time\n\Rightarrow Distance=-0.5* 3=-1.5\ m

The negative sign indicates opposite direction

Movement of Ann will be the sum of the distances

15+(-1.5)=13.5\ m

The net movement of Ann is 13.5 m

Calculate the Energy (E) in joules for that wavelength and record it in the table below. Remember that E = HF, where h the Planck constant (6.6 *10^-34 j*s)

Answers


In that formula for Energy, 'F' is the frequency of the photon.
But Frequency = (speed)/(wavelength), so we can write the
Energy formula as
                                 E = h c / (wavelength) .

So the energy, in joules, of a photon with that wavelength, is . . .

                                 E = (6.6 x 10⁻³⁴) x (3 x10⁸) / (that wavelength)

                                    = (1.989 x 10⁻²⁵) / (that wavelength, in meters) .

A physical science test book has a mass of 2.2 kg what is the weight on mars??? please help

Answers

Weight is defined as a body's mass multiplied by its acceleration due to gravity.

Test Book's weight on mars = 8.1 N.

What is different between mass and weight?

  • The distinction between Mass and Weight is Weight is a measure of force, while mass is a measure of inertia. Many people use these two terms interchangeably.
  • The mass of a body is the amount of matter contained within it, whereas the weight of a body is the force acting on it as a result of gravity's acceleration. In chemistry, this is the primary distinction between mass and weight.
  • Weight is defined as a body's mass multiplied by its acceleration due to gravity.

Weight = (mass) x (gravity)

            = (2.2 kg) x (3.7 m/s^2)

              = 8.1 newtons
