Is potential energy that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system
(a)
The work done on the projectile is 9375 joule.
The work on the projectile is calculated as
W=F×d
=1250×7.5
=9375 joule
(b)
The speed of the projectile after 7.5 m is 27.38 m/s
First we need to find out the acceleration of the projectile
F=m×a
1250=25×a
a=50 m/
Now the velocity of the projectile after 7.5 m is calculated as
v^2=u^2+2a×s
v^2=0+2×50*7.5
v=27.38 m/s
Answer: Explanation:
Plants and animals each produce the gases that the other needs to live. Plants need carbon dioxide—people and other animals exhale carbon dioxide as a waste product. People and other animals need oxygen—plants produce oxygen during an important process called photosynthesis, which turns the sun's energy into nutrients.
No electron with a de Broglie wavelength of 2 μm can not pass through a slit that is 1 μm wide
When studying quantum mechanics, the de Broglie wavelength is a key idea. De Broglie wavelength is the wavelength () that is connected to an item in relation to its momentum and mass. Typically, a particle's force is inversely proportional to its de Broglie wavelength.
Where "h" is the Plank constant, momentum has the formula = h m v = h. The de Broglie equation and de Broglie wavelength are terms used to describe the relationship between a particle's momentum and wavelength. The probability density of locating an object at a specific location in the configuration space is determined by the De Broglie wavelength, which is a wavelength present in all quantum mechanical objects. A particle's momentum and de Broglie wavelength are inversely related.
