When does your heart work the hardest


Work is often defined as how much volume or weight is carried, for how far in a given period of time. Examples: Move 1000 Lbs 10 feet in 10 minutes, Now move it 20 feet in 10 min - you've done twice the work. Or, 2000 lbs 10 feet in 10 minutes = twice the work. 1000 lbs, 10 feet in 5 minutes = twice the work.

So, a good measure for a heart would be how much blood is pumped in a period of time. The amount of blood in each beat doesn't really change, this distance is always the same, so how often it happens is a pretty good indicator. Simplified, you could say that the heart does the most work when it beats the fastest. Run for 130 beats per minute is 4 times the work of say, sleeping at 30 beats in a minute. Anything that raises yur heart rate to the highest would be the most work.

My Velodyne DPS-10 subwoofer hums when you plug in the RCA cable. The hum increases in volume when you touch the rear metal panel.


hi,
You have to check the RCA cable to the sub woofer. The RCA cabe have two connections inside it, one is for gain and the other is for ground sheild. If the ground sheild is broken then there will be hum from the sub woofer and it will increase if you touch the ground (rear metal pannel is connected to the ground). Replace the cable and check it again.
ok

it sounds like a bad sub woofer amplifer, as the unit heats up the capacitors start to leak and the amp will try to shut down. it would depend on how hard you are driving it, (heavy bass versus light bass) that would cause it to fail sooner than later. You need to replace the internal amp
