The answer is the first option "true." According to social exchange theory, altruistic behaviors benefit the individual who performs them is a true statement. That is because the word Altruism means doing acts to benefit themselves.
Hope this helps.
The acceleration of the particle as a function of time t is
The velocity of the particle at time t is the integral of the acceleration:
where the constant C can be found by requiring that the velocity at time t=0 is v=3:
and we find
so the velocity is
The position of the particle at time t is the integral of the velocity:
where D can be found by requiring that the initial position at time t=0 is zero:
x(0)=0
from which we find D=0, so
To solve the problem, now we just have to substitute t=5 into x(t) and v(t) to find the position and the velocity of the particle at t=5.
The position is:
and the velocity is:
Answer:
ocean wave
Explanation:
ocean waves are not a wavelength but produced from the pull of the moons gravitational pull
Answer
Newton's third law is used for the impact test on the vehicle.
In the frontal collision of the vehicle, the impact of the vehicle is made against the concrete wall then the impact on the passengers and driver is calculated.
In the impact test time of the opening of the airbag is also calculated.
Similar tests also take place when the impact is sideways.
