Answer:
the magnitude of the velocity of one particle relative to the other is 0.9988c
Explanation:
Given the data in the question;
Velocities of the two particles = 0.9520c
Using Lorentz transformation
Let relative velocity be W, so
v
= ( u + v ) / ( 1 + ( uv / c²) )
since each particle travels with the same speed,
u = v
so
v
= ( u + u ) / ( 1 + ( u×u / c²) )
v
= 2(0.9520c) / ( 1 + ( 0.9520c )² / c²) )
we substitute
v
= 1.904c / ( 1 + ( (0.906304 × c² ) / c²) )
v
= 1.904c / ( 1 + 0.906304 )
v
= 1.904c / 1.906304
v
= 0.9988c
Therefore, the magnitude of the velocity of one particle relative to the other is 0.9988c
High frequency , it is because wavelength is inversely proportional to frequency
F=MA
F=(8 kg)(9.8 m/s)
F= 78.4 N
W=FD
W=(78.4 N)(7 m)
W=548.8 J

Answer:
meter, kilogram
Explanation:
Here we want to know how big the tiger is. This means that we want to measure its size and possibly its mass.
The size is actually a measure of the length of the tiger, and length is measured in meters.
The mass of an object, instead, is a measure of the "amount of matter" in the substance, and it is measured in kilograms.
The other options are wrong because:
- The second is the unit of time
- The candela is the unit of the luminous intensity
- The mole is the unit of the amount of substance, and it is used for gases
- The ampere is the unit of the current
