<em>Quantities that determine the kinetic energy of a body are its </em><em>mass and velocity </em>

Answer:  <em>mass and velocity </em>

Explanation:

The kinetic energy of a body is the energy possessed by an object by virtue of its motion. It is given by the equation

                                       k= \frac{1}{2}mv^2

Where m represents mass of the body and v represents its velocity.

Two bodies of equal velocity but different mass the heavier body will have greater kinetic energy. When an object is at rest its velocity is equal to zero. Thus its kinetic energy will be zero. Hence it can be concluded that only moving bodies have kinetic energy.

Stationary objects placed at a height possess potential energy which is the energy by virtue of their position or configuration. The total mechanical energy of a system is the sum of potential and kinetic energy.

katrin [286]

Answer:

a = 0.8 m/s^2

Explanation:

Force equation: F = ma

F = ma -> a = F/m = 2.8*10^3 N / 3.5*10^3 kg = 0.8 m/s^2

Light from a laser with wavelength 400 nm passed through two small openings and produces an interference pattern on a screen 1 m
alexira [117]

To solve this problem we will apply the concepts related to destructive interference from double-slit experiments. For this purpose we will define the path difference as,

\text{Path difference}= dsin\theta = (2n-1)\frac{\lambda}{2}

Here,

\lambda = Wavelength

\theta = Angle when occurs the interference point of destructive interference

Our values are given as,

\text{Wavelength} = \lambda = 400nm = 4*10^{-7}m

\text{Distance of Screen} = D = 1m

Using the previous expression we have,

d \times \theta = \frac{\lambda}{2}

d \times (0.1) = \frac{4*10^{-7}}{2}

d = 2*10^{-6} m

d = 2\mu md = 2\mu m

Therefore the distance between the two openings is 2\mu m

On a cosmic calendar, in which the history of the universe is compressed into one year, how long is the average human life span?
netineya [11]

Answer:

If one were to use 5 billion years as the age of the universe and 75 years as the average human life span then

T = 75 / 5 E9 = 1.5E-8

The number of seconds in a year is 3600 * 24 * 365 = 3.2E7

If t = N * T   seconds in a year * fraction of human life span

t = 1.5E-8 * 3.2E7 = .48

A human life span is about 1/2 second compared to the life of the universe if the universe were compressed to a single year
