Answer:
The maximum acceleration amplitude is 40.28 g.s.
Explanation:
Given that,
Full scale suspension = 25 mm
Frequency = 20 Hz
We need to calculate the maximum frequency
Using formula of maximum frequency
Put the value into the formula
We need to calculate the maximum acceleration amplitude
Using restoring force
Using equation of S.H.M
On differentiating
On differentiating again
Maximum acceleration =ω²A
Which is at the maximum amplitude
Hence, The maximum acceleration amplitude is 40.28 g.s.
Answer:
-2.25
Real and inverted image
Explanation:
u = Object distance = 16 cm
v = Image distance = 36 cm
f = Focal length
Lens Equation
Focal length of the lens is 11.07 cm. Positive value indicates the lens is a convex lens
Magnification
Since magnification is negative the image inverted
Answer:
The object in a uniform motion covers same distances in an equal time period. Objects in a non-uniform motion cover dissimilar distances in an equal time period.
Explanation:
The speed of the object traveling in uniform motion is constant, the actual speed and the average speed of the moving body is same.
26,000 years is approximately how long it takes for the earths revolution to change
Answer:
North Hemisphere
Explanation:
It is called "Cancer" because in ancient times when the summer solstice was held in the Northern Hemisphere, the sun was in the constellation of cancer; although this is currently in the constellation of Gemini, near the edge that separates it from Taurus.
This parallel is currently located at a latitude of 23 ° 26'16 "north of Ecuador and travels at a rate of almost half a second per year to the south.
This imaginary line delimits the northernmost points where the sun shines, something that happens between June 20 and 21 every year, this is called the June solstice.
