Answer:

The five components of physical fitness are cardiovascular endurance, muscular strength, muscular endurance, flexibility and body composition, according to Fit Day.

cardiovascular endurance:

Cardiorespiratory endurance:

is the level at which your heart, lungs, and muscles work together when you're exercising for an extended period of time. This shows how efficiently your cardiorespiratory system functions, and is an indicator of how physically fit and healthy you are.

muscular strength:

Muscular strength is defined as the maximum amount of force that a muscle can exert against some form of resistance in a single effort.

muscular endurance:

Muscular endurance is the ability of your muscle or muscle groups to withstand repeated contractions for an extended period.

flexibility and body composition:

Stretching before and after activities will help to improve flexibility. The sit-and-reach and the trunk lift are two tests used to measure flexibility. Body Composition is the percentage of body weight that is fat compared to other body tissue, such as bone and muscle.

5. A 4.00 kg object slides down a frictionless inclined plane with an acceleration of 3.00 m/s2. What is the angle of the inclin
Kazeer [188]

Answer:

The angle of the incline above horizontal is 17.81 degrees.

Explanation:

Given that,

Mass of the object, m = 4 kg

Acceleration of the object above the incline, a=3\ m/s^2

We need to find the angle of the incline above horizontal. The net force acting on the object along the incline is given by :

F_{net}=mg\ sin\theta

ma=mg\ sin\theta

a=g\ sin\theta

sin\theta=\dfrac{a}{g}

sin\theta=\dfrac{3}{9.8}

\theta=17.81^{\circ}

So, the angle of the incline above horizontal is 17.81 degrees. Hence, this is the required solution.

I need help please only way to put my grade up !!!!!! Would appreciate it !!! Someone who’s good at this
motikmotik

Answer:

Total energy = 1000J

KE = 500J

PE = 500J

Explanation:

As you may know, the equation for gravitational potential energy is mgh (weight x height)

If the skateboard is halfway down, that means it is at half the height. As the skateboard speeds up (as it goes downward), the potential energy becomes kinetic energy. Since it has 500J of kinetic energy at half way down, it means it had double that amount of Potential energy at the top (1000J). Since half of that became kinetic energy, there is only 500J of PE left.

Total energy = KE + PE = 1000J

KE = 500J

PE = 500J

What are hot clouds of gaseous elements and compounds that act as nurseries for stars
Aleks04 [339]
Interstellar gas clouds are common in many galaxy, like the Orion nebulae which many young stars are being born. A typical nebula is many light years in diameter and contains enough material mass to make several thousand stars the size of our sun. The majority of the gas in nebulae consist of molecules of hydrogen and helium-but most nebulae also contain atoms of other elements. All known element in our periodic table is also being made inside this crucible of this immense hot gas. The source of the organic molecules is still a mystery. Irregularities in the density of the gas causes a net gravitational force that pull the gas molecules close together.

The “turning effect of a force” (T = F * r) is:
Doss [256]

Answer:

b and e

Explanation:

r x F is the formula for torque.

The "turning effect" or torque happens when concentric forces rotate an object along said center.

a) False because T = Fr = Ia (a = angular acceleration)

b) True

c) False. L = Iw (w = angular velocity), which does not equal Ia

d) False. It is torque, not the product of torque and something else

e) True.
