Answer:
The pressure is
Explanation:
From the question we are told that
The gauge pressure at the mouth is
The radius of the column is
The speed of the liquid outside the body is
The area of the column is
The area inside the mouth
Generally according to continuity equation
=>
=>
=>
So
=>
=>
substituting values
Now the height of inside the mouth is
Now the height of the column is
Generally according to Bernoulli's equation
Now which is the density of water
is the gauge pressure of the atmosphere which is zero
So
Answer:
10N
Explanation:
Equation: ΣF = ma
Fapp = ma
Fapp = (2kg)(5m/s^2) (im guessing you mean 5.00 m/s^2 not m/s)
Fapp = 10*kg*m/s^2
Fapp = 10N
it is important so you can discover new materials or inhabitle planets in case anything happens to earth
The point of science is to disprove wrong theories, and continue our knowledge forward that way. it's a lot easier to disprove something than to prove something as a rule has to fail once to be wrong, while you would have to prove and show that the rule works on every possible scenario for it to be proven, which is impossible. as such, a scientist should question current theories for faults, and confirm ( not prove) or disprove them.
Answer:
26.6 m/s
Explanation:
Given:
Δy = 2.1 m
t = 5.35 s
a = -9.8 m/s²
Find: v₀
Δy = v₀ t + ½ at²
(2.1 m) = v₀ (5.35 s) + ½ (-9.8 m/s²) (5.35 s)²
v₀ = 26.6 m/s
