Term specifically describes small chunks of rocks and debris in space that burn up in Earth’s atmosphere is :
Meteors
Explanation:
- A meteor is a meteoroid or a particle broken off an asteroid or comet orbiting the Sun – that burns up as it enters the Earth's atmosphere, creating the effect of a "shooting star".
- Meteoroids that reach the Earth's surface without disintegrating are called meteorites.
- Due to Earth's escape velocity, the minimum impact velocity is 11 km/s with asteroid impacts averaging around 17 km/s on the Earth. The most probable impact angle is 45 degrees.
- Meteoroids have a pretty big size range. They include any space debris bigger than a molecule and smaller than about 330 feet space debris bigger than this is considered an asteroid.
- But most of the debris the Earth comes in contact with is "dust" shed by comets traveling through the solar system.
- The surface of a meteorite is generally very smooth and featureless, but often has shallow depressions and deep cavities resembling clearly visible thumbprints
- Most iron meteorites, like the example at right, have well-developed regmaglypts all over their surface.
Answer:
Ensure that all material and energy inputs and outputs are as inherently safe and benign as possible. Minimize the depletion of natural resources. Prevent waste. Develop and apply engineering solutions while being cognizant of local geography, aspirations, and cultures.Green engineering is the design, commercialization, and use of processes and products that minimize pollution, promote sustainability, and protect human health without sacrificing economic viability and efficiency.The goal of environmental engineering is to ensure that societal development and the use of water, land and air resources are sustainable. This goal is achieved by managing these resources so that environmental pollution and degradation is minimized.

Answer:
The power of force F is 115.2 W
Explanation:
Use following formula
Power = F x V
= F cos0
= (30) x 4/5
= 24N
Now Calculate V using following formula
V =
+ at
= 0
a =
/ m
a = 24N / 20 kg
a = 1.2m / 
no place value in the formula of V
V = 0 + (1.2)(4)
V = 4.8 m/s
So,
Power =
x V
Power = 24 x 4.8
Power = 115.2 W
This is true. Anything the government does has a positive or negative effect on anything including businesses.
Answer:
6.4 m/s
Explanation:
From the equation of continuity
A1V1=A2V2 where A1 and V1 are area and velocity of inlet respectively while A2 and V2 are the area and velocity of outlet respectively


where r1 and r2 are radius of inlet and outlet respectively
v1 is given as 1.6 m/s
Therefore
