A 5.00-kg box slides 5.50 m across the floor before coming to rest. What is the coefficient of kinetic friction between the floo
Stels [109]

Answer:

μk = 0.08

Explanation:

  • Applying the work-energy theorem, we know that the change in kinetic energy of the box, is equal to the total work done on it.
  • The only force acting on the box capable of doing work, is the dynamic friction force.
  • This force is just the product of  the coefficient of kinetic friction, and the normal force.
  • In this case, if the floor is level, the normal force is equal and opposite to the gravity force, Fg.
  • So we can write the following expression:

       \Delta K = -\frac{1}{2} * m* v_{0} ^{2} = \mu_{k} *m*g* cos (180\º)

  • Replacing by the givens, we can solve for μk, as follows:

       \mu_{k} = \frac{v_{0}^{2} }{2*g*d} = \frac{9 (m/s)2}{2*9.8 m/s2*5.50m} = 0.08

Montesquieu believed that in order for one person not to have all the power government should
IrinaVladis [17]

Answer:

Montesquieu called the idea of dividing government power into three branches the "separation of powers." He thought it most important to create separate branches of government with equal but different powers. That way, the government would avoid placing too much power with one individual or group of individuals.

What adaptation of a cactus protects it from predators? a round cactus with many spines Broad leaves Sharp spines Thick stems Ye
Alex_Xolod [135]

A round cactus with many spines is the adaptation of a cactus that protects it from predators.

A cactus, unlike other plants, has unique adaptations in its roots, leaves, and stems that allow it to flourish in hot and dry surroundings.

The one adaptation that protects the cactus from predators is spines.

A cactus does not have any parts that resemble leaves if you could look at one closely.

Instead, the leaves are transformed into spines, which protrude from the plant's tiny bumps known as areoles.

Herbivores that live in the desert may be enticed to eat the cactus. The spines prevent these predators by modifying leaves into spines.

Other than protection, Spines perform many functions like

1) Since evaporation is a problem in a desert since water is scarce, the spines prevent excessive evaporation.

2)  The spines also impede airflow and prevent evaporation by trapping air.

3) <u>Collecting dew</u> from the early-morning fog is another crucial job that the spines do.

The gathered dew turned into liquid water and ran down to the earth below. The plant then absorbs this water.

Hence, the adaptation of a cactus that protects it from predators is round cactus with many spines.
