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
16,000 m/s
Since it’s speed, and the distance is unknown. Gravity isn’t applying a noticeable force too on the rocket, as if it were, then the rocket would be accelerating negatively.
Answer:
See the answers below.
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
y - yo = Fall distance [m]
Vo = initial velocity = 0 (dropped)
t = time = 6.5 [s]
g = gravity acceleration = 9.8 [m/s²]
Now replacing:
The question is related to the distance between the points where the ball was dropped and the ground.
The variables used are gravitational acceleration, time, fall distance, initial velocity.
Answer:
Since Force is a vector quantity, It depends on both magnitude and direction.
So, the resultant depends also on the direction.
Answer:
"Synthesizers have always had a well-established presence in standard ensembles."
Explanation:
This is an opinion. Not a true statement.
