Answer:
Consistency paradox is the observation that a human being’s personality tends to remain the same over time, while their behavior can change in different situations.
Many personality characteristics are relatively constant throughout a person's life, but people can act in all sorts of ways (even ones that seem to be opposite of their personality) in different situations. For instance, even the most even-tempered and easy-going person can be driven to violence when put under enough stress or pressure.
Answer:
2.57 seconds
Explanation:
The motion of the ball on the two axis is;
x(t) = Vo Cos θt
y(t) = h + Vo sin θt - 1/2gt²
Where; h is the initial height from which the ball was thrown.
Vo is the initial speed of the ball, 22 m/s , θ is the angle, 35° and g is the gravitational acceleration, 9.81 m/s²
We want to find the time t at which y(t) = h
Therefore;
y(t) = h + Vo sin θt - 1/2gt²
Whose solutions are, t = 0, at the beginning of the motion, and
t = 2 Vo sinθ/g
= (2 × 22 × sin 35°)/9.81
= 2.57 seconds
Answer:
Explanation:
By conservation of energy, the sum of the kinetic and gravitational potential energies at the surface of the Earth must be equal than their sum at infinity, so we have:
Where 
is the gravitational constant,
and 
are the mass and radius of the Earth, <em>m </em>is the mass of the particle, 
its velocity at the surface of the Earth (which would be its escape velocity) and 
and 
are the velocities and distance at infinity, which would be null and infinity respectively, so the right hand side of our equation is 0J, which leaves us with:
Also, since the force the molecule experiments is the force of gravity (disregarding drag), we can write its weight in terms of Newton's Law of Gravitation:
Which means that:
So finally putting all together we can write:

Answer:
Explanation:
When we do multiple trials of the same experiment, we can make sure that our results are consistent and not altered by random events. Multiple trials can be done at one time. If we were testing a new fertilizer, we could test it on lots of individual plants at the same time.
