A tuna fish is streamlined to
reduce friction which describes the type of of friction the fish must overcome
drag force. Drag force affects the fall of a tuna fish because the area of a
body has an increase in surface area and hinders the flow of the molecules
around it thus increasing the drag force.
Liquids have definite volume and indefinite shape.
Answer:
About 133 db.
Explanation:
Sound Intensity Level in db (SIL db) is equal to 10log (base 10) times the ratio of the sound intensity at 200 watts (I) relative to the sound intensity of the reference sound intensity (I sub 0), which by default is equal to 10⁻¹² W/m² or 0 dB.
I = 200 w / 10 m^2 = 20 w per square meter
I sub 0 = 10^-12 w per square meter
SIL = 10log ( I / I sub o) = 20 / 10^-12 = 10log ( 20^12) = 10 ( 13.3 ) = 133 db
Hope I typed this part correctly. Hard to get it in without being able to do exponents, etc. :D
Answer: An owl cause it is a organism
Explanation:
1. it`s due to the gravitational pull of earth which causes Moon to orbit the Earth.
2. No,it`s not always noticeable.You must have heard that earth pulls apple so it falls downward but the fact is apple also pulls earth but the pull isn`t noticeable.
3. I have only one thing that is the distance between the masses.
4. The quantity of matter contained in a body is called it`s mass whereas weight of an object is the force of attraction with which it is attracted towards the centre of a planet.Mass of an object is constant everywhere bt weight of an object varies from place to place.Mass is measured by beam balance whereas Weight is measured by spring balance.
5. You will fall back on the surface of earth.It happens because of the force of gravity of the earth.
6. If u jump on the moon u will float away(I guess).
7. Weightlessness is a condition where weight of an object is experienced to be zero.The mass doesn`t change as it remains constant everywhere.I will add an image for this one which may help you.
