Answer:
D. hypothalamus
Explanation:
The autonomic nervous system (ANS) is a component of the peripheral nervous system that is in charge of the involuntary functions, this means it regulates the flight-or-fight response, heart and respiratory rate, sexual arousal, urination, etc.<em> The hypothalamus is the integrator of these functions, it receives the information from the nervous system and responds to it.</em>
I hope you find this information useful and interesting! Good luck!
Time is being measured in days here so if you want to calculate the rate of increase after one day, substitute 1 for t in your rate equation:
dB/dt = 0.677598 cos(1.232(1))
dB/dt = 0.22
<h2>The option ( c ) is correct</h2>
Explanation:
When we apply the force on any body , the inertia comes into play . It is the tenancy of the the body to oppose the force which tends to change its state .
In first case the train tries to change its state from rest to motion . Thus the inertia of rest opposes this tendency.
In the second case , the train tries to come from motion to the state of rest . Thus again , inertia opposes it .
Therefore inertia is the factor which creates difficulty in both case . Hence option ( c ) is correct
Answer:
A=60.06 x 10⁻⁵ m²
Explanation:
Given that
Weight of the person = 864 N
Weight of the bike = 85 N
The total weight ,car + bike ,Wt= 864 + 85 N
Wt = 949 N
2 p = 949 N
The weight on the each tire(F) = 474.5 N
P = 7.9 x 10 ⁵ Pa
We know that
Force = Pressure x Area
F= P A
By putting the values
474.5 = 7.9 x 10 ⁵ A
A=60.06 x 10⁻⁵ m²
Therefore area of contact A
A=60.06 x 10⁻⁵ m²
