Answer:
The electron’s velocity is 0.9999 c m/s.
Explanation:
Given that,
Rest mass energy of muon = 105.7 MeV
We know the rest mass of electron = 0.511 Mev
We need to calculate the value of γ
Using formula of energy
Put the value into the formula
We need to calculate the electron’s velocity
Using formula of velocity
Put the value into the formula
Hence, The electron’s velocity is 0.9999 c m/s.
Personality theorists often focus on differences in individuals.
Answer: Option A
<u>Explanation:
</u>
According to the personality psychology, personality scientists study personality and its variations amongst the individuals. They often focus on the thoughts, judgements and social behaviour of the individuals that they exhibit over time. With these observations, they form a report which better conclude their mental and emotional state.
By studying different types of personalities and respective behaviour, personality theorists are able to predict the diversity in human nature and that whether a person is mentally and emotionally healthy. If not, theorists conduct therapies to get them in order and hence, lead a more meaningful and healthy life.
Answer:
Zero gravity
Explanation:
Astronauts around the earth either in spaceship, a space station or on a space walk appear to be weightless because of the zero gravity in such environment.
Weight is a function of the mass and acceleration due to gravity a body has.
Weight = mass x acceleration due to gravity
In a place where acceleration due to gravity is 0, the weight would be zero and a person would appear to be weightless.
<span>To get that, find the time when slope equals to 0, use the derivate theory from calculus.
s = 8 cos t + 9 sin t, t ≥ 0
s' = -8 sin t + 9 cos t (this is slope)
0 = -8 sin t + 9 cos t
8 sin t = 9 cos t
tan t = 9/8
t = 48.37 seconds</span>
