Describe the gases that are emitting from a volcanic eruption. What affect do they have on the atmosphere and planet?

Physics

torisob [31]3 years ago

The types of gas expelled from a volcanic eruption include water vapor (the most abundant of volcanic gas), carbon dioxide, hydrogen sulfide, hydrogen halides and sulfur dioxide.  When volcanoes erupt, they have a negative effect on the atmosphere and planet because all of the gases emitted (except water vapor) are hazardous to people, animals, plants, and property.  These gases can add to the Greenhouse Effect by causing an increase in temperature.  Some particles such as ash and sulfur dioxide act as an exact opposite by creating a cooling effect, reflecting sunlight away from Earth.  There is also evidence that proves these eruptions can affect short-term weather.

What is the acceleration of a car that moves at a steady velocity of 100 km/h for 100 seconds? Explain your answer.
RUDIKE [14]

Answer:

a = 0 m/s²

Explanation:

given,

car moving at steady velocity = 100 Km/h

         1 km/h = 0.278 m/s

      100 Km/h = 27.8 m/s

time of acceleration = 100 s

acceleration is equal to change in velocity per unit time.

 a=\dfrac{dv}{dt}

change in velocity of the car is 27.8 - 27.8 = 0

 a=\dfrac{0}{100}

        a = 0 m/s²

If the car is moving with steady velocity then acceleration of the car is zero.

Hence, the acceleration of the car is equal to a = 0 m/s²

The component that allows a car to execute complex maneuvers is __________ .
Charra [1.4K]
The anti-lock braking system (ABS) is a car component that enables the driver to execute complex maneuvers. Furthermore, it allows shifting the position of your car when driving on highways because of its ability to "maintain traction." It also can decrease the kinetic energy of your car when you want to make it decelerated.

A satellite of mass m is in a circular orbit of radius R2 around a spherical planet of radius R1 made of a material with density
Anit [1.1K]

Answer: The gravitational force Fg exerted on the orbit by the planet is Fg = G 4/3πr3rhom/ (R1 + d+ R2)^2

Explanation:

Gravitational Force Fg = GMm/r2----1

Where G is gravitational constant

M Mass of the planet, m mass of the orbit and r is the distance between the masses.

Since the circular orbit move around the planet, it means they do not touch each other.

The distance between two points on the circumference of the two massesb is given by d, while the distance from the radius of each mass to the circumferences are R1 and R2 from the question.

Total distance r= (R1 + d + R2)^2---2

Recall, density rho =

Mass M/Volume V

Hence, mass of planet = rho × V

But volume of a sphere is 4/3πr3

Therefore,

Mass M of planet = rho × 4/3πr3

=4/3πr3rho in kg

From equation 1 and 2

Fg = G 4/3πr3rhom/ (R1 + d+ R2)^2
