Answer:
science is define as the study of physics, chemistry, biology, geology and astronomy. science is very important in our daily life.we study science for knowing the knowledge about biological and chemical and many other aspects.without science it is impossible to live our daily life.science is used in each and every steps.
Explanation:
There are many more benefits that we are getting and going to get . Science has already discovered many things ,that we didn't expect efore.And also in progress to discover new things.Science has developed a new type of antivirus that protect us from different virus.Has made different medicine that recover a people. So it is very useful in our life.
Description of an object in projectile motion is;
- Gravity acts to pull the object down.
- The object’s inertia carries it forward.
- The path of the object is curved.
Explanation:
The path of the projectile is usually curved, and NOT straight, due to the influence of gravity on it which is teh only force acting on it-, causing it motion path to fall towards the earth. Most projectiles follow a parabolic path. The projectile, even though it was launched, its motion is then only due to its own inertia – tendency to stay in motion in a straight line, or rest, unless an external force is acting on it - such as drag or friction. An example of such projectile motion is of ballistic missiles.
Answer: 43.58 min
Explanation:
Knowing the volume of a rectangular object is length x width x height, we have two volumes:
And we know it takes a time of 4 minutes to fill 
.
If we want to know how long will it take the same hose to fill another tank with volume 
, we can use the <u>Rule of three</u>, which is a mathematical rule to find out an amount that is with another quantity given in the same relation as other two also known:
---- 
---- 
Finally:
Answer:Silk emitted by the silkworm consists of two main proteins, sericin and fibroin, fibroin being the structural center of the silk, and serecin being the sticky material surrounding it. Fibroin is made up of the amino acids Gly-Ser-Gly-Ala-Gly-Ala and forms beta pleated sheets.

Objects accelerate at ~9.8 Meters per second per second (9.8 Meters peer sec^2. (or ~32 feet per sec^2 for you non metric guys) As they gain speed they will reach a maximum velocity limited by atmospheric resistance, when the resistance vector equals the gravity vector and all acceleration will cease. In a vacuum the object will continue to accelerate.
