Suppose you are taking a walk one day when you see a tree branch snap at its base and begin to rotate downward with the break ne
ar the trunk of the tree as a pivot point. You estimate the length of the branch to be about 3 meters. Estimate the initial angular acceleration of the branch in rad/s2. Can you estimate the mass of the tree branch from this information? Why or why not?
1 answer:
Answer:
α = 3.27 rad/s²
No
Explanation:
Given that
L= 3 m
Lets take mass of tree = m kg
The torque to mass m = m g .L
The mass moment of inertia of tree ,I
I = mL² kg.m²
We know that
τ = I α
m g .L = mL² .α
α= g/L
Now by putting the value
α = 3.27 rad/s²
No we can find the mass of the from the above information because angular acceleration is not depend on the mass of tree.

Explanation:
The magnitude of force required to pull the lid off the box by air pressure.
We know that Pressure, P= Force(F)/Area(A)
Force, F= P×A
Given: A=
P=.
Therefore, F=.
F=
Explanation:
It is given that the number of electrons passing through the cross-sectional area in 1 s is . Also, we know that charge on an electron is
, then negative charge crossing to the left per second is as follows.
I- =
I- = 0.544 A
As it is given that the number of protons crossing per second is , as the charge on the proton is
, then positive charge crossing to the right per second is calculated as follows.
I+ =
I+ = 0.224 A
I = l I+ l + l I- l
So, I = 0.544 + 0.224
= 0.768 A
Thus, we can conclude that the current in given hydrogen discharge tube is 0.768 A.
