Answer: creating electricity from wind

Explanation:

The abundance of greenhouse gases in the atmosphere is increasing due to human activities like deforestation, burning of fossil fuels, and others. The natural factors like volcanic eruption also contribute to this increase. The greenhouse gases like carbon dioxide, carbon monoxide, methane, nitrous oxide and others are added up to the atmosphere. These gases increases the global temperatures hence, are responsible for the phenomena of global warming.

Creating electricity from wind is an energy generation process which does not emit greenhouse gases into the atmosphere. As wind is a renewable source of energy. It is abundantly available in nature. The high speed wind currents are utilized to move the wind turbine which is further used for the  generation of electricity without emitting any kind of poisonous gas in the atmosphere.

Diferencia entre transferencia y transformación de energía. Da ejemplos de cada caso.
Firdavs [7]

Answer:

La transformación de energía es un proceso en el que la energía se intercambia entre un sistema y el medio ambiente en al menos dos formas de energía diferentes entre sí. Por ejemplo, un panel solar convierte la energía lumínica en energía eléctrica.

En cambio, en la transferencia de energía, esta no cambia su forma sino que es transmitida de un cuerpo a otro. El ejemplo más claro es el de la fogata, que transmite calor al medio ambiente a través de radiación.

15.One girl was involved in a bus crash. She told the police that she was seated in the last line of seats and that when the bus
Alona [7]

Answer: It is not likely.

Explanation:

When the bus is moving forward, all the objects inside of it also are moving forward.

Now, as the objects inside the buss are not fixed to the bus, if the bus suddenly stops the objects inside of it will keep moving forward, because of the conservation of the momentum, defined as the quantity of motion (Similar to when you are in a car and it suddenly stops, you can feel the forward impulse).

Then is not likely that, in a case where the bus stops suddenly, an object inside the bus flies backward in opposite direction to the previous movement of the bus.

How much force is needed to accelerate a bicycle and rider with a total mass of 50 kg at a rate of 2.0 m/s2 ?
True [87]

Answer:

The answer is D 100 newton

Explanation:

2.0m/s2 is d acceleration while the 50kg is the mass. Force = mass x acceleration. So f=50x2.so force is 100 newton

If someone throws a 3 gram fry accelerating at 5 meter/second2, what is the fry’s force?
Alex

Answer:

0.015 m/s2

Explanation:

Using Newtons 2nd law.

F = ma where F = Force applied, m = mass of the object and a = acceleration acquired.

So substitute the values in SI units.

m = \frac{3}{1000} kg

Therefore F = 0.003×5 = 0.015 m/s2
