◦
980 N

◦
200 N

◦
98 N

◦
49 N

◦
Some value other than those given above.


Question 2

When a car goes around a circular curve on a level road without slipping,

◦
no frictional force is needed because the car simply follows the road.

◦
the frictional force of the road on the car increases when the car's speed decreases.

◦
the frictional force of the road on the car increases when the car's speed increases.

◦
the frictional force of the road on the car increases when the car moves to the outside of the curve.

Addicts to opiates often avoid treatment because they are afraid of withdrawal. Though unpleasant, with proper management, withdrawal is rarely fatal and passes relatively quickly.

Did you know?

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).

Did you know?

Certain topical medications such as clotrimazole and betamethasone are not approved for use in children younger than 12 years of age. They must be used very cautiously, as directed by a doctor, to treat any child. Children have a much greater response to topical steroid medications.

Did you know?

Lower drug doses for elderly patients should be used first, with titrations of the dose as tolerated to prevent unwanted drug-related pharmacodynamic effects.
