Answer:

$v = 10.89\ m/s$

Explanation:

given,

radius of loop = 12.1 m

to find the minimum speed transverse by the rider to not to fall out upside down

centripetal force = $\dfrac{mv^2}{r}$

gravitational force = m g

computing both the equation]

$mg = \dfrac{mv^2}{r}$

$v = \sqrt{rg}$

$v = \sqrt{12.1 \times 9.8}$

$v = \sqrt{118.58}$

$v = 10.89\ m/s$

Which of the following is responsible for the overall integration of the autonomic nervous system (ANS)?

Dafna1 [17]

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. The hypothalamus is the integrator of these functions, it receives the information from the nervous system and responds to it.

I hope you find this information useful and interesting! Good luck!

During a circus act, a performer thrills the crowd by catching a cannon ball shot at him. The cannon ball has a mass of m1 = 8.5

lbvjy [14]

Answer:

$v = 0.92 m/s$

Explanation:

As we know that there is no external horizontal force on the cannon ball + performer

So here total momentum of the system must be conserved

so we will have

$m_1v_1 = (m_1 + m_2) v_f$

$m_1 = 8.5 kg$

$v_1 = 8.1 m/s$

$m_2 = 66 kg$

now from above equation we have

$8.5 \times 8.1 = (8.5 + 66) v$

$v = 0.92 m/s$

Various singly-ionized atomic nuclei of the same speed are directed into a magnetic field in a mass spectrometerwhere they are d

ki77a [65]

Answer:

a) least mass

Explanation:

According to the Newton's first law of motion, more the mass of a body the greater is its inertia, and inertia is the tendency of a body to resist any change to its state of rest or uniform motion.

Greater is the mass of charge least is its deflection under the influence of magnetic field.

This can be explained well by the mathematical equations relating the centripetal force and the magnetic force on a charged mass moving in a magnetic field perpendicular to the velocity:

$m.\frac{v^2}{r} =q.v.B$

where:

m = mass of the charged particle

v = velocity of projection of the charged mass into the magnetic field

r = radius of curvature of path of charged mass under the magnetic force

q = magnitude of charge on the particle of mass 'm'

B = intensity of magnetic field normal to 'v'

$\Rightarrow v=\frac{q.B.r}{m}$

$\Rightarrow v\propto \frac{1}{m}$

i.e.

Speed of the charge is higher when its mass is lesser and according to the Fleming's left hand rule we known that the charge continuously faces a magnetic force while moving in the field.

& also,

$\Rightarrow m\propto \frac{1}{r}$

Which indicates that more is the mass of charge larger is the radius of its trajectory of motion which means lesser is its deviation.
