Answer:
Explanation:
The frequency equation for waves is
where f is the frequency, v is the velocity, and lambda is the wavelength. Filling in:
so
v = .26(25) and
v = 6.5 meters/second
Answer:
0.0016 cm
Explanation:
= Thermal coefficient of expansion of brass =
= Thermal coefficient of expansion of glass =
= Change in temperature =
= Initial radius = 4 cm
Change in radius of material is given by
Difference in radii of the lid and jar
The size of the gap is 0.0016 cm or 0.000016 m
Answer:
5.234 m/s^2
Explanation:
Weight (force due to gravity) is proportional to the acceleration due to gravity. For some g' on MPAW, the relation is ...
g'/g = (2714 N)/(5185 N)
g' = g(2714/5185) = (10 m/s^2)(2714/5185)
g' ≈ 5.234 m/s^2
