Ok this is hard but I think the answer is 34
Answer:
The work done by the force on the particle is 29.85 J.
Explanation:
The work is given by:
Where:
x₁: is the lower limit = 0 m
x₂: is the upper limit = 1.9 m
Fₓ: is the force in the horizontal direction = (4.5 + 13.7x - 1.5x²)N
Therefore, the work done by the force on the particle is 29.85 J.
I hope it helps you!
Answer:
v = 17.71 m / s
Explanation:
We can work this exercise with the kinematics equations. In general the body is released so that its initial velocity is zero, the acceleration of the acceleration of gravity
v² = v₀² - 2 g (y -y₀)
v² = 0 - 2g (y -y₀)
when it hits the stone the height is zero and part of the height of the seagull I
v² = 2g y₀
v = Ra (2g i)
let's calculate
v =√ (2 9.8 16)
v = 17.71 m / s
Answer:
The current is 0.951 A
Solution:
As per the question:
Capacitance of the capacitor, C =
Resistance of the circuit, R = 14.0
Voltage of the battery, V = 10.0 V
Now, when the charge become one-fourth of its initial value, the amount of current flowing is given by:
(1)
where
q' =
Now,
The current is given by:
(2)
Also,
Now, using the value of I = 0.714 A
Answer:
The controlled variable is the correct answer.
