4. An 85 kg object has 2.16 x 10 J of kinetic energy. What is the object's velocity?​
RUDIKE [14]

Answer:

v = 0.713[m/s]

Explanation:

Kinetic energy is defined as the product of mass by the squared velocity of a body. In this way with the following expression we can have the kinetic energy as a function of velocity.

E_{kin}=0.5*m*v^{2}

where:

m = mass = 85 [kg]

v = velocity [m/s]

Ekin = kinetic energy = 2.16*10 [J]

2.16*10 = 0.5*85*v^{2}\\v =\sqrt{0.508} \\v= 0.713[m/s]

compare and contrast the medical understanding of death (that you have read about and learned about in this chapter) and the pop
mixer [17]

The medical understanding of death is related to the scientific approach, and the popular understanding is related to the inclusive spiritual and cultural approaches.

<h3 /><h3>What is death for science?</h3>

Death occurs when an individual's cardiorespiratory and brain functions cease due to some factor, thus ending his life.

Popular understanding, on the other hand, is aligned with scientific knowledge, but it is also encompassing cultural and religious teachings, which define topics not proven by science, such as life after death for example.

Therefore, death is a delicate topic for society, and spirituality is the basis found for greater emotional comfort in individuals who suffer significant losses of loved ones.

- A particular light source gives off light waves with a measured wavelength of
skad [1K]

Answer:

f = 1.5 x 10¹⁵ Hz

Explanation:

Light is an electromagnetic wave and we know that the speed of light is a constant which is 

3 x 10⁸ m/s.

Knowing this; v = λ x f

λ = wavelength

f= frequency of light

v = seed of light

f = v/λ

f =  3 x 10⁸m/s / 2.0 x 10-⁷ m

f = 1.5 x 10¹⁵ Hz

Which best describes the weak nuclear force? It is weaker than the gravitational force, with a greater range than the weak nucle
labwork [276]

Weak nuclear force is weaker than the strong nuclear force with a smaller range than the electromagnetic force.

It acts between fermions with spin 1/2 basically quarks and leptons. It has a range of 10⁻¹⁸ meters.

Option 1 is incorrect. It is stronger than the gravitational force.

Option 2 is incorrect. It is weaker than the electromagnetic force.

Option 3 is incorrect. It has a smaller range than the strong nuclear force.
