Answer:

84

Explanation:

From the question given above, it is evident that 222 86Rn is emitting alpha particle since the daughter nuclei produced has a mass number lesser than 4 when compared to parent element.

Therefore, the miss value in the equation is 84.

A fan blade rotates with angular velocity given by ωz(t)= γ − β t2, where γ = 5.20 rad/s and β = 0.810 rad/s3 . calculate the an
Gnesinka [82]

Answer : The angular acceleration is \alpha=-\beta t=-0.810\text{ t}

Solution : Given,

\gamma=5.20rad/s

\beta=0.810rad/s^3

The given angular velocity equation is,

\omega_z(t)=\gamma-\beta t^2

At t = 0,    \omega_z(0)=\gamma

At t = t,      \omega_z(t)=\gamma-\beta t^2

Angular acceleration : It is defined as the rate of change of angular velocity with respect to time.

Formula used for angular acceleration :

\alpha=\frac{\omega_z(t)-\omega_z(0)}{t}

where,

\alpha = angular acceleration

\omega_z(t) = angular velocity at time 't'

\omega_z(0) = angular velocity at time '0'

t = time

Now put all the given values in this formula, we get the angular acceleration.

\alpha=\frac{(\gamma)-(\gamma-\beta t^2)}{t}

\alpha=-\beta t=-0.810\text{ t}

Therefore, the angular acceleration is \alpha=-\beta t=-0.810\text{ t}

Lotions applied during winter season moisturize the skin very quickly. What could be the reason for this?
irina1246 [14]
I think the correct answer from the choices listed above is option C. Lotions applied during winter season moisturize the skin very quickly. This is because the oils in the lotion enter the skin cells by means of facilitated diffusion. Hope this answers the question.
