Opening the valve allows more of the pressurized material out. If the area is decreased, less of the pressurized material is released, and its force ends up more spread out, reducing the pressure. Opening the valve will increase volume of transfer of your liquid.
Answer:
Peak current = 16.9 A
Explanation:
Given that
RMS voltage = 120 Volts
AC is connected across resistance
now by ohm's law
now peak value of current will be given as
Answer:
3.2 m/s
Explanation:
Given:
Δx = 1000 m
v₀ = 23 m/s
a = -0.26 m/s²
t = 76 s
Find: v
This problem is over-defined. We only need 3 pieces of information, and we're given 4. There are several equations we can use. For example:
v = at + v₀
v = (-0.26 m/s²) (76 s) + (23 m/s)
v = 3.2 m/s
Or:
Δx = ½ (v + v₀) t
(1000 m) = ½ (v + 23 m/s) (76 s)
v = 3.3 m/s
Or:
v² = v₀² + 2aΔx
v² = (23 m/s)² + 2(-0.26 m/s²)(1000 m)
v = 3.0 m/s
Or:
Δx = vt − ½ at²
(1000 m) = v (76 s) − ½ (-0.26 m/s²) (76 s)²
v = 3.3 m/s
As you can see, you get slightly different answers depending on which variables you use. Since 1000 m has 1 significant figure, compared to the other variables which have 2 significant figures, I recommend using the first equation.
Condition for diffraction
Where
a = Distance between slits
m = Order of the fringes
= Wavelength
= At the angle between the ray of light and the projected distance perpendicular between the two objects
For small angles
Where
Where L is the distance between the slits and Y the length of the light.
Replacing we have
The distance between slits d can be expressed also as 
Where N is the number of the fringes, then
Similarly when there is added a new Fringe we have the change of the distance would be :
Linear distance between fringes is
Therefore the answer is
Answer:
101 J
Explanation:
The kinetic energy of an object is given by
where
m is the mass of the object
v is its speed
For the baseball in this problem,
m = 0.140 kg
v = 38.0 m/s
Substituting into the equation, we find the kinetic energy of the ball:
