Passengers in an aircraft are subject to the Normal and Gravity Force acting on them at a low 'orbit', so tiny that it can be many times compared to the same surface of the earth when speaking in general terms.
In a high orbit space vehicle or in the same space, said force decreases considerably or simply disappears, generating the sensation of weightlessness.
Remember that the Force of Gravity is given under the principle
Where,
G = Gravitational Universal constant
M = Mass of the planet
m = mass of the object
r = Distance from center of the planet
When the radius grows considerably the gravitational force begins to decrease.
Answer:
500 N
Explanation:
Natural bouyency will keep the diver in the same place, no matter what the mass of gfs. This means if the diver is displacing with a weight of 500 N, the upthrust will also be 500 N.
How many mL is an espresso?
One shot of espresso is generally about 30–50 ml (1–1.75 oz), and contains about 63 mg of caffeine (3). Important point: The “golden ratio” for espresso is this: a single shot is 30 to 44 mL (1 to 1.5 ounces) of water and 7 grams of coffee
Six centimeters equal to about two inches
Answer:
A.3.64 m
Explanation:
Because
- v=(fλ)
- (1382)=(380)λ
- λ=3.637m~3.64m
<em>where</em><em> </em><em>,</em><em>v</em><em>=</em><em>velocity</em>
<em>f</em><em>=</em><em>frequency</em><em> </em>
<em>λ</em><em>=</em><em>wave</em><em> </em><em>length</em><em> </em>
