A) Vi= 60 m/s
a= -9.81 m/s^2
Vf= 0m/s^2
d=?
Vf^2=Vi^2+2ad
(0m/s)^2=(60m/s)^2+2(-9.81m/s^2)d
0=3600+(-19.62)d
-3600=(-19.62)d
(-3600)/(-19.62)=(-19.62)d/(-19.62)
d=183.5m
c) Vi= 60 m/s
a= -9.81 m/s^2
Vf= 0m/s^2
t=10s
d=?
d=Vi*t+(1/2)a*t^2
d=60m/s(10s)+(1/2)(-9.81m/s^2)(10s)^2
d=600+(-4.905)(100)
d=600+(-490.5)
d=108.5m
Answer:
adaptive optics.
Explanation:
Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.
A lens can be defined as a transparent optical instrument that refracts rays of light to produce a real image.
A telescope can be defined as an optical instrument or device which comprises of a curved mirror and lenses used for viewing distant objects i.e objects that are very far away such as stars and other planetary bodies.
The technique called adaptive optics uses a high-speed computer to monitor atmospheric distortion and adjust the optics of a telescope to partially compensate for the seeing.
Basically, adaptive optics is used by astronomers to correct the distortions caused by the turbulence of the atmospheric conditions of the Earth in real-time, so as to have an image that is as sharp as anyone taken in space.
We can't tell from the information in the question.
Weight = (mass) x (acceleration of gravity).
In order to find any of those quantities, we need to know
the other TWO things.
We can't answer the question until we know either the mass
of the book, or its weight on some other planet other than Venus.
Time in the universe vs the population
Answer:
<em>the mass of the original unstable particle is</em><em> 1115.08 MeV/c²</em>
Explanation:
The momentum of a particle is determined by:
p = e B R
where
- B is the magnetic field
- R is the radius of curvature
- e is the energy of the particle
Therefore,
p = e B R kg · m/s
We can transform the units to MeV/c and we do that by taking:
e = 0.511 MeV and
c = 3 × 10⁸ m/s
Therefore,
p = 300 B R MeV/c
p = 300(0.250 T)(1.33 m) MeV/c
p = 99.75 MeV/c
The energy of the unstable decayed particle is determined as:
E = √ [m²c⁴ + p²c²]
where
- m is the mass of the particle
- c is the speed of light
- p is the particle's momentum
Therefore,
E = E_p + E_(π⁻)
E = √[ (938.3)² + (99.75)² ] + √[ (139.5)² + (99.75)² ]
E = 1115.08 MeV
Since the particle was initially at rest, its energy is only rest-mass energy so its <em>mass will be 1115.08 MeV/c²</em>
