Answer:
roughly 2.2 atm
Explanation:
using Boyle's law (P1V1=P2V2),
73×1.3=43×x
x= 2.21 or 2.2 atm
Answer:
See answer below
Explanation:
Hi there,
To get started, recall the Center of Mass formula for two masses:
where m is mass and x is displacement <em>from the center of the shape.</em>
Since masses at the center of a geometric shape have a displacement (x) value of 0, as the mass is already of the center, and does not affect Xcm. So, we can disregard the central mass, hence we use the above formula for two masses.
We can arbitrarily define left to be a negative (-) displacement, and vice versa for right direction. We proceed with the formula:
Since we defined left (-) and right (+), we notice the center of mass is (+) value. This makes sense, as there is slightly more mass on the right side. Hence, you should place a support 1/6 of the rod's length away from the rod's center.
Study well and persevere.

Pitch is related to frequency
Answer:3.96 m/s
Explanation:
Given
Rock is thrown to a height of 0.8 m
We know that energy is conserved
Total Energy=kinetic Energy+Potential Energy
At bottom Kinetic Energy is maximum and Potential energy is minimum while at the top potential Energy is maximum and kinetic energy is minimum
Energy at Bottom 
Energy at Top 
Thus





All the feelings of balance, or of losing it or falling or being dizzy, come from the "semi-circular canals" deep in the inner ear.
