Answer:
increase
Explanation:
think of climbing a mountain. the higher you go the harder it is to breathe. its because air pressure is increasing
Given:
Horizontal distance between two boats = x = 14 m
One boat is at trough, the other is at crest.
As there is no crests between them meaning the boat are next to each other.
Wavelength is the distance between two consecutive crests/troughs = w
The distance between a crest and a trough next to it = w/2
Complete cycles = c = 5
Time taken for c cycles = t = 15 s
Vertical distance between two boats = y = 2.4 m
To find:
wavelength = w = 2x = 28 m
Amplitude = A = Displacement from mean to extreme position = y/2 = 1.2 m
Time period for one cycle = T = t/c = 15/5 = 3 s/cycle
frequency = 1/T = 1/3 = 0.33 hertz
speed = wavelength/Period = w/T = 28/3 = 9.33 m/s
Electric current can be generated by moving a metal wire through a magnetic field It is also different than static electricity, which is the accumulation of charges on a surface. Electric generators rotate a coil of wires through a magnetic field.
<h2>
Tension in ropes are 333.33 N and 566.67 N.</h2>
Explanation:
Refer the given figure showing the arrangement.
For having stability we have torque at A and B are zero.
Sum of Torques at A = 0
700 x 1 + 200 x 1.5 - Q x 3 = 0
3Q = 1000
Q = 333.33 N
Sum of Torques at B = 0
200 x 1.5 + 700 x 2 - P x 3 = 0
3P = 1700
P = 566.67 N
Tension in ropes are 333.33 N and 566.67 N.
