Answer:
the speed of the fluid in the wider section of the pipe is 1m/s.
Explanation:
By equation of continuity we can write (for ideal (non-viscous, in-compressible).
A_1,A_2 are areas of the pipe at inlet and outlet of the pipe.
_1
Here, d_1 , d_2 are diameters of inlet and outlet, also v_1, v_2 are velocities at inlet and outlet.
putting values we get
solving we get
Answer
given,
y(x,t)= 2.20 mm cos[( 7.02 rad/m )x+( 743 rad/s )t]
length of the rope = 1.33 m
mass of the rope = 3.31 g
comparing the given equation from the general wave equation
y(x,t)= A cos[k x+ω t]
A is amplitude
now on comparing
a) Amplitude = 2.20 mm
b) frequency =
f = 118.25 Hz
c) wavelength
d) speed
v = 105.84 m/s
e) direction of the motion will be in negative x-direction
f) tension
T = 27.87 N
g) Power transmitted by the wave
P = 0.438 W
Answer:
Tides on our planet are caused by the gravitational pull of the Moon and Sun. Earth's oceans "bulge out" because the Moon's gravity pulls a little harder on one side of our planet (the side closer to the Moon) than it does on the other. The Sun's gravity raises tides, too, but lunar tides are twice as big.
What we must know to determine the direction of the magnetic force on a charge are;
- The direction of the magnetic field.
- The velocity of the charge.
<h3>How to find the direction of magnetic force?</h3>
The magnetic force is the force of attraction or repulsion that emerges between electrically charged particles since of their movement.
From right hand rule, to determine the direction of the magnetic force on a charge, we must know;
- The direction of the magnetic field.
- The velocity of the charge.
