I got you kid It’s A- 2.5m/sb
Answer:
The frequency as calculated is 0.79 Hz
Solution:
As per the question:
Mass of the beam, m = 225 kg
Mass of the sack, m' = 175 kg
Amplitude, A = 40.0 cm = 0.4 m
Frequency, f = 0.6 Hz
Now,
(A) To calculate the frequency of the SHM:
The total mass, M = m + m' = 225 + 175 = 400 kg
With the help of the eqn:
where
k = spring constant
Thus
Squaring both sides, we get:
k = 5684.89 N/m
Now, after the gravel has fallen:
m = 275 kg
Now,
The frequency of the SHM can be calculated as:
2nd class leaver refers to such leaver in which load lies between effort and fulcrum.In a nut cracker too load is in between effort and fulcrum.Thus, nut cracker is a 2nd class leaver.......
An externality, sometimes called a spillover, occurs when an exchange between a buyer and seller has an impact on a third party who is not part of the exchange. Externalities can be positive or negative
<h3>What are Externalities?</h3>
Externalities refers to situations when the effect of production or consumption of goods and services imposes costs or benefits on others which are not reflected in the prices charged for the goods and services being provided.
Externalities Private markets offer an efficient way to put buyers and sellers together and determine what goods are produced, how they are produced, and who gets them. The principle that voluntary exchange benefits both buyers and sellers is a fundamental building block of the economic way of thinking. But what happens when a voluntary exchange affects a third party who is neither the buyer nor the seller?
Externalities can be negative or positive. If you hate country music, then having it waft into your house every night would be a negative externality. If you love country music, then what amounts to a series of free concerts would be a positive externality.
