At the lowest point in a vertical dive (radius = 0.58 km), an airplane has a speed of 300 km/h which is not changing. Determine

murzikaleks [220]

Answer:

The centripetal acceleration is $a = 11.97 \ m/s^2$

Explanation:

From the question we are told that

The radius is $r = 0.58 \ km = 0.58 * 1000 = 580 \ m$

The speed is $v = 300\ km /hr = \frac{300 *1000}{1 * 3600 } = 83.33 \ m/s$

The centripetal acceleration of the pilot is mathematically represented as

$a = \frac{v^2 }{r}$

substituting values

$a = \frac{(83.33)^2 }{580}$

$a = 11.97 \ m/s^2$

If the electrons are attracted more by the nucleus because of an additional proton, what would happen to it?

Rus_ich [418]

Answer:

orbital speed of the electrons in their orbit will increase

Explanation:

As we know that centripetal force for electrons will be due to electrostatic attraction force of electron.

So it is given as

$F_e = F_c$

so we have

$\frac{(Ze)(e)}{4\pi \epsilon_0 r^2} = \frac{mv^2}{r}$

now on the left side if the force of attraction will increase and hence there must be the change in that part of equation

So here at the same position the speed of the electron

So we can say that correct answer will be

orbital speed of the electrons in their orbit will increase
