Why can you see the moon and the sun sometimes in a clear sky during the day. I have seen this in the mornings when i have my 'fresh air' break at work!

A 173 g object is attached to the end of an unstressed vertical spring (of constant 32.8 N/m) and then dropped. Acceleration of gravity is 9.8 m/s^2.

1. How far does it drop before coming to rest momentarily (in units of m)?

2. What is the maximum speed (in units of m/s)?

Have block B on table weight=711 N, coefficient of static friction is 0.25. Have cord attatched horizontally to B, goes to knot. Another cord is attatched to knot at 30 deg. from horizontal and is attatched to wall. Another cord from knot is vertical, and is attatched to block A. What is the maximum weight of A that will allow the system to remain stationary?

how to make a metal air battery ?
I want to know that how can i make a "Metal Air Battery" for a science project and it should be a working model ???
thats means a working model of "MEtal AIr Battery".

I have seen and heard all about the northern lights..but I never have heard anything about the South Pole...does it have electromagnetic activity similar to the North ?? Does it have Aurora Borealis displays ?? Would the South Pole be the + or - pole ??

1. There are 3 resisitors: R1 (103mA) is attached to a circuit that flows to the right into a node which splits into 2 additional resistors (which are in parallel). R2 (77.5mA) is on the top branch. R3, has an unknown current, which I believe is 22.5mA (If I am using the Kirchoff's Law appropriately - if not please let me know).

2. If the resistance on R3 =4.70kOhms, what is the voltage drop across R2 using Kirchoff's Voltage Law?

3. What is the resistance of R2?

4. If the EMF applied to the circuit is 225V, what is the voltage drop across R1?

5. What is the resistance of R1?

I WILL PICK A BEST ANSWER!!!

Thanks in advance :-)

From the following heats of reaction,

2C (graphite) + H2 (g) --> C2H2 (g) H = 227 kJ

6C (graphite) + 3H2 (g) --> C6H6 (l) H = 49 kJ

calculate the heat for the reaction

3C2H2 (g) --> C6H6 (l)
