Answer:
The required amplitud is 0.11cm
Explanation:
To solve this problem it is necessary to apply the concepts related to simple harmonic motion, where displacement is given by
Where,
A = Amplitude
f = Frequency
t = time
If we derivate the expression we can obtain the Acceleration, there
x would be A for the minimum amplite of vibration, then
Replacing with out values,
Therefore the required amplitud is 0.1146cm
B
when hurricanes hit land, it weakens them
Answer:
no. the moon has less of a gravitational pull. therefore it would weigh less than 40n.
Explanation:
Answer:
A. Period is halved
Explanation:
The period of a pendulum swing, T, is given in terms of mass as:
where I = moment of inertia
m = mass of the pendulum
g = acceleration due to gravity
h = Length of string
If the mass is increased by a factor of 4, that means:
M = 4m
(M = new mass)
The new period of the pendulum, , will now be:
Hence, the period is halved.
Answer: 144 g
the mol of the oxygen gas is 64/16 = 4 (mol)
we have:
2H2 + O2 => 2H2O
4 ------> 8
=> the mol of H2O is 8 mol
=> m(H2O) = 8.(2 + 16) = 8.18 = 144 (g)
