Answer:
f = 8 %
Explanation:
given,
density of body of fish = 1080 kg/m³
density of air = 1.2 Kg/m³
density of water = 1000 kg/m²
to protect the fish from sinking volume should increased by the factor f
density of fish + density of water x increase factor = volume changes in water
1080 +f x 1.2 =(1 + f ) x 1000
1080 + f x 1.2 = 1000 + 1000 f
998.8 f = 80
f = 0.0800
f = 8 %
the volume increase factor of fish will be equal to f = 8 %
The answer is B. They can only go through solid NOT liquid
Answer:
FA / FB = 100
Explanation:
given two identical cars
let their initial speed be U m/s
for car 1 let it deaccelerates with a1
0 = U² - 2*a1*(10cm)
a1 = U² / (2*(0.1))
car2 deaccelerates with a2
0 = U² - 2*a2*(10)
a2 = U² / (2*(10))
FA = m*a1
FB = m*a2
FA/FB = a1 / a2
= 10/0.1
= 100
FA/FB = 100
Answer:
Planet Y
Rx = 1.587 Ry
Explanation:
Tx = 290 days
Ty = 145 days
Let the semi major axis of planet X is Rx and of plant Y is Ry.
According to the Kepler's third law of planetary motion
Rx = 1.587 Ry
So, planet Y is closest to star.
