I cannot fully answer this question because you have not specifically defined who Clark is. If I knew his full name I might be able to help you more
Acceleration = (change in speed) / (time for the change)
<em>Acceleration = -- (speed as you crossed the finish line) / (10 seconds)</em>
We can answer this problem by dimensional analysis. As we can see, the units of the electric field strength is newtons per coulomb. If we multiply a value with units of coulomb we will obtain newtons which is a units of force.
Force = 9.4x10^7 N / C (8.1 x10^-9 C)
Force = 0.7614 N
B. An ear squeeze occurs when the pressure inside the middle ear space is less than ambient (surrounding) pressure.
<h3>When external ear squeeze occurs</h3>
External ear squeeze occurs when gas trapped in the external ear canal remains at atmospheric pressure while the external water pressure increases during descent.
Thus, we can conclude that, an ear squeeze occurs when the pressure inside the middle ear space is less than ambient (surrounding) pressure.

<h3>Which factors affect the critical angle for a given pair of media?</h3>
The factors which affect the critical angle are
(a) The colour (or wavelength) of light
(b) The temperature
(i) Effect of colour of light: The critical angle for a pair of media is less for the violet light and more for the red light. Thus the critical angle increases with the increase in wavelength of light.
(ii) Effect of temperature: The critical angle increases with increase in temperature because on increasing temperature of medium, its refractive index decreases.
According to the question,
μ 1 sinCR =1
μ 2 sinCY =1
μ 3 sinCB =1
μ 1 > μ 2 and μ 2 > μ 3
⟹μ 1 > μ 2 > μ 3
CR < CY < CB
Thus,
The critical angle increases with the increase in wavelength of light.
