Newton's law of action/reaction

The force would be the same is the answer

In any collision, there are always four quantities which are the same for both objects involved in the collision. Each object experiences the same force (Newton's third law) for the same amount of time, leading to the same impulse, and subsequently the same momentum change. Only the acceleration and the velocity change can differ for the two objects. The object with the least mass always receives the greatest velocity change and acceleration.

You brought back memories from when I was in college at UNC

### Need to mo we an electrical power point in a brick wall in my apartment

Brick wall is inside apartment... what is on other side of wall?
Open existing electrical box. Drill through back of box and drill through wall until you come out on other side of wall. Install new box #1 on wall where drill comes out. Run conduit over to another new box#2. Drill through wall again until you come out on inside brick wall where you want to relocate original box. Install new surface-mount box#3 on brick wall. Then run wiring from original box. Original box cannot be bricked over or covered with building materials since it is a junction box where wires connect.
Other option is to install extension ring on top of existing electric box. Run conduit across face of brick wall. Install new box#1 where you need outlet.
Other option is to chisel away the brick and mortar from existing electric box down to floor level (or over to door frame). This will allow recessed conduit that can be concealed with matching mortar. Then run conduit across to new location. Cover conduit along floor with baseboard, or chisel out brick along floorline to accommodate conduit, then mortar over conduit. Or simply paint conduit to match brick. You must use conduit since wires cannot be run openly.

### I bought a board game called knock out by Milton Bradley. There were no instructions on how to play. Do you know the rules on how to play?

The wiki for the game has the rules ill post them here for convenience:

Before the game begins, a wall of 24 bricks (plus one "Knockout" brick) is constructed. A template is provided to assist where the bricks should be placed in the wall. These bricks can be 1, 2, or, 3 blocks wide. The bricks are made of clear colored plastic. The 25th brick, also known as the "Knockout" brick (colored solid black in the Milton Bradley version and solid blue in the Hasbro version) is three blocks wide, and is placed on the top of the wall, directly in the middle. The template shows exactly where to place this brick as well.

Players first must roll a special die that has four colors on it and two stars. If a color is rolled, the player must knock out a brick of that color, out of the wall. If the player rolls a star, the player may knock out any brick they wish (with a few exceptions, see below). Players take turns using a motorized hammer known as the "Rammer Hammer", in an attempt to knock out the specified brick out of the wall, without making the wall collapse, OR making the "Knockout" brick fall off the wall. If a player is successful in knocking out the brick, without the wall collapsing, or the "Knockout" brick falling off the wall, they must put the brick back, on the top of the wall. Each player thereafter must accomplish the same task.

The rules for hammering are:

• A player cannot touch the wall in any way, except with the hammer
• Once you begin to hammer a brick out of the wall, a player cannot change their mind, even if it becomes obvious that hammering the brick any further will make the wall collapse.
• A player cannot hammer any brick on the same row or a row higher than the "Knockout" brick

A player is allowed an attempt to make the wall more stable by using the hammer to stabilize the wall before they commit to hammering out a brick, but once a player starts to hammer a brick out of the wall, they can not change their mind.

If at any time during a player's turn, the wall collapses, or the "Knockout" brick falls off the wall, that player is eliminated from the game, the wall is rebuilt, and play starts again with the next player in line.

If only one player remains, they win the game.

### The power brick on my xbox 360 is red and is not overheating yet i smaell burning plastic from my xbox 360 console anyone have any tips?

A red light on the xbox 360 power brick usually indicates the Xbox 360 console has a short circuit. Here is how to be sure:

1. Try unplugging the power brick from the wall and from the xbox 360.
2. Wait about 30 seconds and plug the power brick into the wall power outlet.
3. Make sure the indicator light on the power brick is orange. ( If it's not orange then get yourself a new power brick and try again ).
4. Plug the power brick into the Xbox 360 console and try to power it on.
If your power brick turns red or you get an immediate three red ring error than you will need to have the console professionally repaired.
If your warranty with Microsoft has expired; the company I work for GATpro Repairs offers this service at a low flat rate and we pay for the return shipping.
Good Luck and I hope this has helped!

### How do I fix my Endurance Treadmill TF3i Err7 problem? I stopped during operation.

Unplug unit remove motor shroud check connections on lower board (incline board). I believe their is a 3 amp fuse in circuit check with multi meter to see if open replace fuse power up unit and if it blows the fuse then replace incline motor and if not, then use engine mode press stop then Incline + or - to force incline up to max incline then bring it down to 0 then turn off power then wait 10 seconds then hit power on then if error does not appear then hit start and resume using unit. If the procedure above does not activate unit then replace board.

### I have an extension in my house where the bricks are flaking and crumbling. its not rising damp as the bricks are very dry. the worst affected areas are just under the window sills. Please help Vladimir

Check all round the window and ensure a good seal with the brick and sill [use silicon sealant at the joint between the window frame and the brick & sill and brick] and that the sill has a drip bar [ridge or channel under the sill running sideways at the furthest away from the wall] If not put one on the underside. Almost anything will do [sounds silly but an elastic band will do temporary or even a line of the silicon] so long as it collects the drips from the sill. also ensure that the sill slopes downward & away from the wall
How old is the extension ?? I ask because if it is 50+ yrs you may have lime mortar which lets the bricks breath and if this has been re-pointed later with non- lime mortar [i.e. portland cement mortar] any water which gets in above will not escape out through the lime mortar below.
Secondly, if this is a north or east facing wall getting little sun and if the bricks were originally not good, frost & freezing will cause the flaking.
Bricks - has the wall been built with facings or commons. commons will spoil [flaking] sooner.
Do your bricks have a frog. That is a hollow in the middle [& looks a bit like a cake which has sunk in the middle] The frog should be facing down otherwise water will collect You can only check this by taking a brick out [applies mainly to modern bricks ]

### Missing key

Once back inside the temple, the first three floors will be basically the same,
with a few minor exceptions. When you get to B1, head up to the switch you
went to the first time, but instead of hitting it, bomb the rocks to the left
for a shortcut to the key. Grab it and run to the door, saving you a lot of
time.

For the second floor of the temple, you will still need to hit the two switches
to drop the key down, but instead of pulling the lever behind the Phantom, you
can bomb the wall directly south of the entrance for another shortcut. Grab
the key, then proceed the same way as the first time, through the blue and red
blocks. Head for the locked door, but this time stop at the safe zone for a
bit, and head just west of there and bomb the wall, revealing a 30 second bonus
to your Hourglass. Then you may proceed downstairs.

The third floor follows an almost identical procedure as the previous run.
First, grab the Force Shard in the northwest corner and take it to the
pedastal. Once that's taken care of, head east and bomb the rocks for an
additional 30 seconds. Then, head just south and use the Boomerang to hit the
switch, stopping the nearby spikes. Then, head to the southeast corner, grab
hit the switch to lower the fires, you can use the shovel to reveal a rising
wind that will carry you to the top platform so that you can get the key.
Kill the Phantom, grab the key, and head to the locked door. Grab the last
Force Shard and return it to its pedastal, then proceed through to the next
room. Run to the far left side of the room, grab the 30 seconds, then head
back to the Door of Wisdom and proceed through and down the stairs.
