Answer:
The causes of this resistive force are molecular adhesion, surface roughness, and deformations.
Explanation:
Adhesion is the molecular force resulting when two materials are brought into close contact with each other.

Answer:
Amplitude = 4.725 mm
Explanation:
We have got the following values :
T = 98.4 N
T is the wire tension
v = 406 m/s
v is the transverse waves speed
f = 60.5 Hz
f is the frequency
ΔU = 0.391 W
ΔU is the average power carried by the wave
If μ is the mass per unit length of the wire ⇒ μ =
If ω is the angular frequency of the wire ⇒ ω = 2π.f
So ω = 2π(60.5 Hz) and ω units are
The equation that relates all is :
ΔU = (1/2).(T/v^2).(ω^2).(A^2).v
Where A is the wave amplitude
This will give us A in meters
Answer:
B
Explanation:
You would have rain. You would have clouds, precipitation, and strong winds.
Answer:
(a) (1) -32ft/s
(2) -25.6ft/s
(3) -24.8ft/s
(4) -24.16ft/s
(b) -24 ft/s
Explanation:
First of all, we need the position for every instant mentioned in order to calculate average velocities:
Y(2) = 2 ft
Y(2.5) = 0 ft
Y(2.1) = 13.44 ft
Y(2.05) = 14.76 ft
Y(2.01) = 15.7584 ft
Let's now calculate average velocities:
Now, for the instantaneous velocity, we derive the expression for y:
V(t) = 40 - 32t For t=2s V(2) = -24ft/s
For an automobile spring using a 25 kg car battery, the spring constant is mathematically given as
K=4.08.3N/m
<h3>What is the spring constant?</h3>
Question Parameter(s):
a 25 kg car battery
The springs are pulled out by 0.06 meters
Generally, the equation for the Force is mathematically given as
F=mg
Therefore
F=(25*9.8)
(25*9.8)=K(0.06)
K=4.08.3N/m
In conclusion, the spring constant
K=4.08.3N/m
