I'm not understanding how to
find the inertia of these objects. Any help would be great.
Thanks!

I'm a bit confused on how to
go about this question. Any help would be great, thank you!
The resistivity of gold is 2.44x10-8 •m at room temperature. A gold wire that is 0.7 mm in diameter and 41 cm long carries a current of 140 mA. What is the electric field in the wire? 2.2x10-2 V/m 1.1x10-2 V/m 7.0x10-3 V/m 2.2x10-3 V/m 8.9x10-3 V/m
I'm stuck on these questions guys. Any help is appreciated 1) How great is the terminal voltage on a battery while measuring its maximum current? 2) How great is the current delivered by a battery while measuring its EMF? 3) What would happen if you alter the polarity of one of the batteries in a circuit containing 2 batteries in series? 4) How many batteries are needed in order to increase both EMF and the maximum current (in a circuit...

Question 13 of 20 > Consider a titration of 50.0mL sample of 0.500 M HCl (a strong acid, which contains 0.0250 moles H:07) with 0.400 M NaOH (a strong base). Determine the pH of the solution after 15.0 mL of NaOH (0.00600 moles of OH) is added.
I'm having some trouble with this question. Not sure how to go
about solving it. Any help would be appreciated. Thanks.
An object is made up of a disk (M=7.0kg, R=2.0m) and two point
masses (m1=3.0kg and m2=4.0kg). The
arrangement of the disk and the point masses are shown in the
figure and the dimensions are d1=1.0m,
d2=1.5m, d3=0.5m, d4=1.0m, and
t=0.3m.
A. What is the x-coordinate of the center of mass of the
object?
B. What is the z-coordinate...
I'm having a lot of trouble understanding how this is written.
Do they mean "uncompressed length of the spring"? But then, L would
be the length of the bar, not the compressed spring. Please help
me. Thanks
The unstretched length of the string is Lo. Show that when the system is in equilibrium the angle α satisfies the relation sin a 2(Lo - 2F/k)/L. 4
Lost on this question, any help would be great.

3. Draw the major products of the following reactions:
Hi, I'm not sure how to answer this question, any help is appreciated thanks! Why is it more convenient to use sheet resistance to model interconnect? Thanks!
I’m a bit lost on how to approach this question. Any help would
be great, thank you!
Which of the following have the configuration? CH2CH3 CH2CH3 --CH3 CH,CH -CH=CH2 H3C OHH CH3 CH(CH3)2 only 1 only 1 and 2 only 2 1, 2 and 3
I have two questions I'm having trouble understanding. I greatly
appreciate any help you all can give me! I'm not great at physics
so the more details the better.
THANKS!!!
In the RC circuit of Figure WG32.6, the emf of the AC source is given by 'E = Emax sin ω| t. The emf amplitude is Emax = 10 V, and the angular frequency is ω,-100 s-1 when the angular frequency is changed to a new value ω2, the time...
How does Newton’s concept of inertia help us understand why massive objects don’t accelerate faster than smaller ones in a gravitational field?
