Answer:
B. They get their energy from the sun
Explanation:
Plants are producers because they produce their own food by getting energy from the sun. A consumer gets food by consuming other organisms.
Hope this helps friend.
Answer:
the rocket average speed is 12 kilometers per second
Explanation:
Given that
The distance is 1140 km
And, the time is 95 seconds
We need to determine the average speed in kilometers per second (km/s)
So as we know that
Speed = distance ÷ time
= 1,140 km ÷ 95 seconds
= 12 kilometers per second
hence, the rocket average speed is 12 kilometers per second
Weather is a complex phenomena. in order to solve engineering problems such as the prediction of weather, we utilize degrees of freedom (DoF)... weather is one of the many elements that need millions of DoF and still cannot accurately predict it. mainly it's a vector analysis much akin to finite element analysis where each micro degree of freedom or say molecule of air is represented as one point interconnected in a web of points and each point's properties are altered relatively (similar principles how autonomous mini drones coordinate synchoronously) to each other.
many factors are considered: pressure, temperature and density of the air for sure. friction factors. drag factors. rotation of the earth. and that's the natural phenomena. include the heat given off the land, the radiation from the sun, airplanes, people, etc... its highly complicated. having done a weather station project, it's fair to say that there isn't a simple answer to your simple question. we measured wind direction, wind current, temp and humidity, visibility, pressure, etc... and we couls measure these things, but can't really say why say the wind went east or west... except tell you that its because of millions of degrees of freedom interacting with each other simultaneously and some things like weather are just like that.
C is the answer. Hope this helps.
