What is the difference between kinetic and potential energy?
Evgen [1.6K]

Answer:

Difference Between Kinetic Energy and Potential Energy. Energy implies as the object's capability to perform work. ... While kinetic energy is the energy which an object contains because of a particular motion. On the other hand, potential energy is the stored energy, because of its state of rest.

On what scale is the explosivity of a volcano measured?
never [62]

Answer: 1 to 8

The Volcanic Explosivity Index (VEI) is a measure of the explosiveness of volcanic eruptions. It was devised by Chris Newhall of the United States Geological Survey and Stephen Self at the University of Hawaii in 1982. The index is based on a scale of 1 to 8, 1 being very small, and 8 being huge and very rare.

a car of mass 800 kg is travelling at 12m/s the car accelerates over a distance of 240 m there force causing this acceleration i
alisha [4.7K]

Answer:

See below

Explanation:

Force X distance = work

 200 N * 240 m = 48 000 N-m = 48 000 j

F = ma

200 = 800 a

a = 1/4 m/s^2

d = v t  + 1/2 a t^2

12 m/s t  + 1/2  1/4 m/s^2  t^2 = 240

                shows t = 17 sec  (via Quadratic Formula)

final velocity = 12 + at = 12 + 1/4(17) = 16.26 m/s

A slit of width 0.01 mm has light of wavelength 600 nm passing through it onto a screen 60 cm away. how wide (in cm) is the cent
liubo4ka [24]

A slit of width 0.01 mm has light of wavelength 600 nm passing through it onto a screen 60 cm away.  The central maximum will be 7.2 cm .

The central maximum is the brightest central portion of the diffraction pattern. The central maximum is the widest and has the maximum intensity.

The diffraction pattern involves a central bright fringe, also known as the central maxima. Furthermore, central maxima is surrounded by dark and bright lines known as the secondary minima and maxima.

Given

slit width = 0.01 mm = .01 * 10^{-3} m

wavelength = 600 nm = 600 * 10^{-9} m

distance from screen = 60 cm = 60 * 10^{-2} m

width of central maxima = (2 * lambda * D) / d

                                        = 2 * 600 * 10^{-9} * 60 * 10^{-2}  / .01 * 10^{-3}

                                        = 7.2 * 10^{2} m
