Air pollution is an example of a. The underground economy. B. An external shock. C. A nonmarket activity. D. A negative external
devlian [24]

Answer:

D. A negative externality.

Explanation:

Particulate pollution is a form of pollution that is responsible for the degradation of the environment.

Particulate matter is also referred to as particle pollution or atmospheric aerosol particles and it can be defined as a complex microscopic mixture of liquid droplets and solid particles that are suspended in air.

An externality is typically an unwarranted cost or benefit by a manufacturer or producer of goods and services that affects a third party.

In Economics, an externality could either be positive or negative depending on its effect on a third party.

A negative externality arises when the production or consumption of a finished product or service has negative impact (cost) on a third party.

In conclusion, air pollution is an example of a negative externality because it causes harm to a third party.

La tierra aplica una fuerza de atracción de 1000 N sobre un satélite de comunicaciones. La masa del satélite es más de un millón
vaieri [72.5K]

Answer:

La magnitud de la fuerza aplicada por el satélite sobre la Tierra es de 1000 N

Explanation:

De acuerdo con la tercera ley del movimiento de Newton, tenemos que para cada acción (fuerza), aplicada en el universo, existe una fuerza de reacción igual y opuesta

Por lo que un objeto A ejerce una cantidad de fuerza sobre otro objeto B, entonces la fuerza ejercida por el objeto B sobre A es igual en magnitud y opuesta en dirección a la fuerza que proviene del objeto A

Por lo tanto, dado que la Tierra ejerce una fuerza de 1000 N sobre el satélite, entonces la magnitud de la fuerza que el satélite también ejerce sobre la Tierra = 1000 N

758 j of heat are added to 0.750 kg of copper. how much does its temperature change?(unit=degrees c) PLEASE HELPPPPPPP MEEEEEE
Basile [38]

Answer:

2.6^{\circ}C

Explanation:

When a certain amount of heat energy is supplied to a substance, the temperature of the substance increases according to:

Q=mC\Delta T

where

Q is the amount of heat energy supplied

m is the mass of the substance

C is the specific heat capacity of the substance

\Delta T is the change in temperature

In this problem:

Q = 758 J is the heat supplied

m = 0.750 kg is the mass

C=385kg/JC is the specific heat of copper

Solving for \Delta T, we find the increase in temperature:

\Delta T=\frac{Q}{mC}=\frac{758}{(0.750)(385)}=2.6^{\circ}C
