Explanation:
wavelength =200cm=2m
frequency is reciprocal of wavelength
f=1/2
f=0.5Hz or 1/s
Answer:
Dog
Explanation:
(Mass)(velocity) > (Mass delta) (velocity delta)
When the engine is near the governed RPMand the transmission is in the lower gears, the braking effect of the engine is at its greatest .
It is specified that the legal requirements for the braking system that:
A reasonable distance should be practiced in stopping your vehicle.
Adjournment from the jar or shudder should be smooth and free.
A good braking system’s other necessities are:
Unaffected by heat, water, road grit, dust etc.
Constant continued application while moving downwards from a hill should not decrease its effectiveness and it must have good anti fade characteristics
Adequate durability with economical maintenance and adjustment Its durability must be enough and must have proper adjustment and maintenance.
Answer:
Minimum angular spread (in rad) = 547.45 x 10⁻⁶ rad
Explanation:
GIven;
Wavelength of manganese vapor laser beam = 534 nm = 534 x 10⁻⁹ m
Diameter = 1.19 mm = 1.19 x 10⁻³ m
Find:
Minimum angular spread (in rad)
Computation:
Minimum angular spread (in rad) = 1.22[Wavelength / Diameter]
Minimum angular spread (in rad) = 1.222[(534 x 10⁻⁹) / (1.19 x 10⁻³)]
Minimum angular spread (in rad) = 2[448.73 x 10⁻⁶]
Minimum angular spread (in rad) = 547.45 x 10⁻⁶ rad
Answer:
amplitude is 8.92 cm
speed of block is 44.11 cm/s
Explanation:
given data
mass = 0.650 kg
spring constant = 18 N/m
speed = 47 cm/s = 0.44 m/s
speed at x point = 0.350 A
to find out
amplitude of subsequent oscillation
solution
we know here conservation of energy
maximum kinetic energy = maximum potential energy
here we know k is spring constant and m is mass and A is amplitude and v is velocity
so solve it we get
A =
put here all these value
A =
A = 0.08931 m
so amplitude is 8.92 cm
and
by conservation of energy
initial energy = final energy
=
solve we gey V
V =
put here value Vm = 0.47 , and x = 0.350
V =
V = 0.4411 m/s
so speed of block is 44.11 cm/s
