Answer:
The neuron is the basic working unit of the brain, a specialized cell designed to transmit information to other nerve cells, muscle, or gland cells. Neurons are cells within the nervous system that transmit information to other nerve cells, muscle, or gland cells. Most neurons have a cell body, an axon, and dendrites.
Blood group antigens. Blood is classified into different groups according to the presence or absence of molecules called antigens on the surface of every red blood cell in a person's body. Antigens determine blood type and can either be proteins or complexes of sugar molecules (polysaccharides).
Answer:
Acceleration,
Explanation:
It is given that,
Initial speed of the jetliner, u = 69 m/s
Final speed of the jetliner, v = 6.1 m/s
Distance covered, s = 750 m
We need to find the average acceleration of the jetliner. It can be calculated using third equation of motion as :
So, the average acceleration of the plane during landing is . Hence, this is the required solution.
If the vector sum (net value) of the forces on an object is not zero, then it must be accelerating.
Answer:
(a) 3.5 s
(b) 28.6 m/s
(c) 34.34 m/s
(d) 44.64 m/s
Explanation:
(a)
where is initial velocity which is zero hence
where t is time and g is acceleration due to gravity taken as 9.81 m/s2
Making t the subject,
Substituting y for -60 m and g as -9.81 m/s2
and rounding off
t=3.5 s
(b)
Let be horizontal component of velocity
Since the range then making the subject
and substituting R for 100m, t for 3.5 s then
and rounding off
(c)
The vertical component of velocity before hitting ground
but is zero hence
and substituting g for -9.81 m/s2 and t for 3.5 s
rounded off as -34.34 m/s
(d)
The velocity before it hits the ground will be
