Answer: Thermal energy transfer involves the transfer of internal energy. The three types of thermal energy transfer are conduction, convection and radiation. Conduction involves direct contact of atoms, convection involves the movement of warm particles and radiation involves the movement of electromagnetic waves.
Explanation:
Answer:
100
Explanation:
= Resistivity of axon
r = Radius of axon
t = Thickness of the membrane
= Resistivity of the axoplasm
Speed of pulse is given by

So, radius is given by

If radius is increased by a factor of 10 new radius will be

So, The radius will increase by a factor of 100.
Answer:
19,551 J!
Explanation:
The formula is PE = ham (h=height, a= acceleration or 9.8, m= mass)
PE = (95)(9.8)(21)
PE = 19,551 Joules
Energy that transfers through the medium
Answer:
The y-component of the car's position vector is 670m/s.
The x-component of the acceleration vector is -3, and the y-component is 40.
Explanation:
The displacement vector of the car with velocity

is the integral of the velocity.
Integrating
we get the displacement vector
:

Now if the initial position if the car is

then the displacement of the car at time
is


Now at
, we have

The y-component of the car's position vector is 670m/s.
The acceleration vector is the derivative of the velocity vector:

and at
it is

The x-component of the acceleration vector is -3, and the y-component is 40.
