Which of the following is the best reason to rest muscle groups between workouts?
vovangra [49]

Answer;

It allows the muscles time to heal.

Explanation;

-It is very important to rest muscles between workouts. In fact, resistance training breaks down muscles causing microscopic tears. It is only during rest when the muscle-building process is stimulated and the regeneration of new tissue occurs.

-But when muscles are not allowed adequate rest and recover time, the regeneration process cannot occur. This can have several side effects such as increased soreness, decreased strength and performance, and may lead to injury.

If the volume of a sample of gas is reduced at constant temperature, the average velocity of the molecules _______, the average
VLD [36.1K]

Answer:

Explanation:

If the volume of a sample of gas is reduced at constant temperature, the average velocity of the molecules increases, the average force of an individual collision increases, and the average number of collisions with the wall, per unit area, per second increases.

As volume is reduced, the gas molecules come closer together, which increases the number of collisions between them and their collisions with the container walls. Also, since the distance traveled by each molecule between successive collision decreases, the molecule velocity doesn't decrease much within collisions as a result of which, the average velocity is higher compared to when the gas is stored in a larger volume. Finally, due to constant collisions, the direction of molecule travel changes rapidly owing to which the acceleration of molecules increases.

Please help guyss!!!
Savatey [412]

Explanation:

The distance traveled north ward  = 2 miles

       distance traveled south ward  = 3miles

 Displacement is the distance traveled in a specific direction. So, it depend on the start and finish point.

       The displacement  = 3 miles  - 2miles  = 1mile southward

Distance is the total length of path;

        Distance  = 3 miles + 2 miles = 5miles
