Is it true you work better in a mild climate than a humid climate?

yes it is true because mild climate gives you a chance to kinda work more effectively, while humid climate gives you more of a hot and tiring work approach.


Do enzymes work better on larger foods or smaller foods?

Enzymes do not necessarily work better on smaller or larger foods. Enzymes work better when food is broken up or chewed and the enzymes are allowed to circulate freely around the food.


If only external force can change the velocity of a body how can the internal force of the brakes bring a car to rest?

It is not the force of the brakes that is stopping the car but rather external force of friction between tires and the road. Notice that no matter what the force at the brakes is, the car won't stop if there is no friction there(ie. the road is slippery). This is an excellent question. Consider the NASA space shuttle. It has brakes, yet the brakes work only on the ground - only while the shuttle is landing. Why? In space, the brakes have nothing to react against. So, as the questioner suspects, the internal forces of the brakes alone are not sufficient to change the velocity of the space shuttle. But once the shuttle lands, and is rolling down the runway, applying the brakes creates friction between the wheels and the runway. And it is the external force of the runway pushing back against the braking wheels that causes the shuttle to slow down.

Brakes work going backwards better than going forwards?

If your brakes work going backwards better than forwards, you should replace your front brakes. You can get your rotors turned to save time, as well.


Do drum brakes work better than disk brakes?

No, they are inferior to disc brakes. Drum brakes were used from the beginning of the auto up until the late 60s. Drum brakes are more prone to overheating than disc brakes. Disc brakes also shed water much better than drum brakes which improves stopping distance in wet conditions. Disc brakes apply pressure more evenly than drum brakes thus improving stopping distance. Disc brakes are superior in every way.

When are drum brakes better than disc brakes?

Disc brakes tend to dissipate heat better and do not collect nearly as much dust as drum brakes (which traps the brake dust in the drum with nowhere to go), so disc brakes will work better as a rule. Pad wear tends to be more even. Also, the rear wheel cylinders do not rust out and fail as often as with drum brakes.The drawbacks are with discs are:1) When using metal-based pads (common these days), disc rotors tend to warp far more often, especially on the front. They will tend to squeal more unless anti-squeal shims are fitted to the back of the pads.2) Drum brakes warm up faster in very cold weather.3) Loose gravel stones wedged between the rotor and calipers will cause damage.4) When driving through wheel-deep water, disc brakes (especially with metal-based pads) do not work as well as drums until the rotors spin the water off.5) When used as a parking brake, rear drums tend to work better.There is no situation they are better. Disc brakes are superior in every way.When used as a parking brake the drums tend to work better.

yes, but the brakes work slightly differently than a standard passenger car. they use different pressure on each corner of the wheel to compensate for the track theyre on


On a 1997 Saturn Car brakes work fine then hard to push?

S-series brakes are notorious for being much different than any other cars brakes. They have alot more "Feel" to them and seem harder than other vehicles. This is normal. As long as they dont loose pressure they are fine
