I think the answer is 25J
Answer:
A) F = -9.8 N
, B) F = 18.62 N
Explanation:
The Archimedes principle states that the thrust force is equal to the liquid farts dislodged by the body.
Let's apply Newton's equations
F = B –W
Thrust force is
B = ρ_water g V
Let's reduce volumes to the SI system
V = 14.3 L (1 m³ / 1000 L) = 14.3 10⁻³ m³
A) Tank full of air
m = 12.4 +2.9 = 15.3 kg
F = ρ_water g V - mg
F = 1 10³ 9.8 14.3 10⁻³ - 15.3 9.8
F = 140.14 -149.94
F = -9.8 N
The negative sign indicates that the force is descending
B) Empty tank
m = 12.4 kg
F = 1 103 9.8 14.3 10⁻³ - 12.4 9.8
F = 140.14 - 121.52
F = 18.62 N
Force is up
Answer:
the weight of alien is 200 newtons
Explanation:
The computation of the alien weight is shown below:
Given that
Acceleration = 20m/sec^2
And, the mass is 10 kg
So, the weight of alien is
= 20 × 10
= 200 newtons
hence, the weight of alien is 200 newtons
