Answer:

Radius 20 m.

Explanation:

Given:

aₙ = 1.4 m/s²

V = 5.3 m/s

___________

R - ?

Centripetal acceleration:

aₙ = V² / R

Radius:

R = V² / aₙ

R = 5.3² / 1.4 ≈ 20 m

A country is deciding what to do about pollution given off by power plants.
ale4655 [162]

Answer:

The correct option is B

B) Scientists can measure how much pollution is given off.

Explanation:

A) To determine what kind of plants do people want, a polling or a survey is carried out. It is not the job of a scientist to carry that out.

B) Scientist have derived various techniques to measure different kinds of pollution. For example, air pollution can be derived from the Air Quality Index, which measure the quality of the air. The higher the value of Air Quality Index, more is the pollution.

C) Scientists are not allowed to pass any laws regarding pollution. Any kind of laws, including those related to pollution are passed by the Congress.

D) Most of the powerplants in US are owned by private business, while some are under control of the government.

two resistors of resistance 6 ohm and 3 ohm are connected in series and then in parallel .calculate the equivalent series resist
Nutka1998 [239]

Answer:

a. RT = 9 Ohms

b. RT = 0.5 Ohms

Explanation:

Let the two resistors be A and B.

Let RT be equivalent resistance.

Given the following data;

Resistor A = 6ohms

Resistor B = 3ohms

a. To find the equivalent series resistance;

RT = RA + RB

RT = 6 + 3

RT = 9 Ohms

b. To find the equivalent parallel resistance;

RT = 1/RA + 1/RB

Substituting into the equation, we have

RT = 1/6 + 1/3

RT = 3/6

RT = 0.5 Ohms

Vlad1618 [11]
Energy: the capacity for vigorous activity; available power.
Kinetic Energy: the energy of a body or a system with respect to the motion of the body or of the particles in the system.
Law of Conservation of Energy: energy cannot be created or destroyed, but it can be transferred or transformed from one form to another.
Potential Energy: the energy of a body or a system with respect to the position of the body or the arrangement of the particles of the system.
Transfer: to move energy from one to another.
Transform: to change in form, appearance, or structure; metamorphose.

next time you need definitions quickly looking up a dictionary would be faster, anyways hopefully this can be helpful.
