Answer:
Frequency = 2Hz
Explanation:
In simple harmonic motion,
Frequency is given by the formula;
f = (1/2π)√(k/m))
Where,
k is spring constant and
m is mass
Now, the question says there are 4 suspension springs with each having a spring constant of 47100 N/m. Thus, the total amount of spring constant will be;
K_total = 4 x 47100 N/m = 188,400 N/m
Thus, let's now find the frequency since we have m = 1190kg
f = (1/2π)√(k/m)
f = (1/2π)√(188400/1190)
f = (1/2π) x 12.5825
f = 0.159149 x 12.5825 = 2 Hz
(1).....opaque -object that not allow light to pass through it
we can't look through opaque objects
ex..wall
translucent... objects that all some light to pass through it
we can partially see through it
ex...coloured glass window
transparent... objects that wholly allow light to pass through it
we can clearly see through it
ex...glass of specs
(2)..the bouncing back of light from a smooth polished surface is called reflection of light
(3)/.....there must be a solid ,opaque to block light
there must be a source of light
there must be a surface to have shadow on it..
(6)...reflected images r formed by light reflection from a smooth polished surface while shadows are formed by blockage of light by an solid,opaque object...
Answer:
Maximum weight that can be lifted = 18,000 N
Explanation:
Given:
Cross-sectional area of input (A1) = 0.004 m²
Cross-sectional area of the output (A2) = 1.2 m
²
Force (F) = 60 N
Computation:
Pressure on input piston (P1) = F / A1
Assume,
Maximum weight lifted by piston = W
Pressure on output piston (P2) = W / A2
We, know that
P1 = P2
[F / A1] = [W / A2]
[60 / 0.004] = [W / 1.2]
150,00 = W / 1.2
Weight = 18,000 N
Maximum weight that can be lifted = 18,000 N
Answer:
180 degrees
Explanation:
if the waves are in phase this means that their frequency is doubled or amplitude is doubled
Answer:
Fusion is the change of phase from: solid to liquid.
Explanation:
Fusion is defined as change of of a substance from solid state to liquid state.Also known as melting.
Solid → liquid (Fusion)
Vaporization is defined as change of of a substance from liquid state to gaseous state.
liquid → gas (vaporization)
Freezing is defined as change of of a substance from liquid state to solid state.
liquid → solid (solidification)
Deposition is defined as change of of a substance from gaseous state to solid state.Also known as melting.
Gas→ solid (deposition)
Sublimation is defined as change of of a substance from solid state to gaseous state.Also known as melting.
Solid → gas (sublimation)
Condensation is defined as change of of a substance from gaseous state to solid state.Also known as melting.
Gas→ liquid (Condensation)
