One gram of carbohydrate, protein, fat and alcohol provide calories as follows

A 24-hour dietary recall, a food record and a food frequency questionnaire represent the ________ type of assessment

The primary determinant of most consumers’ decisions on whether to consume a food is:

How much work must be done by frictional forces in slowing a 1000.0 kg car from 21 m/s to rest?

The figure shows two forces of equal magnitude acting on an object. If the common magnitude of the forces is 1.2 N and the angle between them is 41°, what third force will cause the object to be in equilibrium?

A 1000.0 kg automobile is moving at 35 m/s at a height of 5.0 m above the bottom of a hill when it runs out of gasoline. The car coasts down the hill and then continues coasting up the other side until it comes to rest. Ignore frictional forces and air resistance.  What is the height h (see figure), where the car comes to rest?  

An astronaut applies a force of 500 N to an asteroid, and it accelerates at 7.00 m/s2. What is the asteroid’s mass?  

A 1000.0 kg automobile is moving at 25 m/s at a height of 5.0 m above the bottom of a hill when it runs out of gasoline. The car coasts down the hill and then continues coasting up the other side until it comes to rest. Ignore frictional forces and air resistance.  What is the height h (see figure), where the car comes to rest?  

How much force does it take to stretch a 10.0 m long, 1.0 cm diameter steel cable by 6.0 mm ? The Young’ s modulus of steel is 2.0×1011 N/m2.  

How much force does it take to stretch a 5.0 m long, 1.0 cm diameter steel cable by 3.0 mm ? The Young’ s modulus of steel is 2.0×1011 N/m2.
