Answer:

A simple depolarization can be defined as any change that occurs in a neuron that results to it being more positive than resting potential, but an action potential happens only when the simple depolarization reaches the threshold or optimum level.

What is the energy of a photon with a frequency of 3.6 × 1015 Hz? Planck’s constant is 6.63 × 10–34 J•s.

zloy xaker [14]

Frequency =v=3.6×10^15Hz

We know

$\boxed{\sf E=hv}$

$\\ \sf\longmapsto E=6.63\times 10^{-34}J\times 3.6\times 10^5s^{-1}$

$\\ \sf\longmapsto E=23.86\times 10^{-29}J$

$\\ \sf\longmapsto E=2.3\times 10^{-28}J$

New York and Los Angeles are about 3000 mi apart, the time difference between these two cities is 3 h. Calculate the circumferen

satela [25.4K]

Answer:

circumference of earth = 24000 miles

Explanation:

given data

New York and Los Angeles distance = 3000 mi

time difference = 3 h

to find out

circumference of the Earth

solution

we find speed first that is

speed = $\frac{distance }{time}$

speed = $\frac{3000}{3}$

speed = 1000 mph

now we know speed of earth is

speed = $\frac{circumference of earth}{time of rotation}$

circumference = speed × time of rotation

and we know earth take 24 hours to rotate at its axis

circumference of earth = 1000 × 24

circumference of earth = 24000 miles

While goofing off at the ice skating rink, a student takes off her shoes and places each of them on the ice. Her friend, a hocke

sukhopar [10]

Answer:

Right shoe

Explanation:

Let the mass and velocity of incoming puck be m and v respectively.

Momentum of the colliding puck will be mv

In case of first case , the momentum of puck becomes zero so change in momentum after collision with left shoe

= mv - 0 = mv

If time duration of collision be t

rate of change of momentum

= mv / t

This is the force exerted by puck on the left shoe .

Now let us consider collision with right shoe

momentum after collision with right shoe

- mv

change in momentum

= mv - ( - mv ) = 2mv

If time duration of collision be t

rate of change of momentum

= 2mv / t

This is the force exerted by puck on the right shoe .

Since the force on the right shoe is more , this shoe will have greater speed

after collision.
