Which description explains how inertia changes the effects of gravity on objects in the solar system?
natita [175]

The answer is; D

Inertia is the tendency of an object to resist change to its velocity and direction.  The bigger the mass of an object the higher its inertia. In space, the celestial bodies with a bigger mass have more inertia and have a higher gravitation pull (because they bend space-time more than smaller objects). The gravitational force of bigger objects influences on other celestial bodies and beats their inertia force by causing them to change direction and speed.

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}

Convert 4 x 10^-3 dL to cm^3 <br><br> Please give the work and the answer in scientific notation.
Serhud [2]

4 x  10^{-3 in dL will be 4 x  10^{-1}  cm^3

<h3>Conversion from dL to cm^3</h3>

Recall that:

Deci = 10^{-1}

Centi = 10^{-2}

Thus, 1 dl = 100 ml

This means that converting from dl to  cm^3 requires multiplying by 10^2.

Applying this principle, 4 x 10^{-3 in dL to  cm^3 will be:

4 x 10^{-3 x  10^2 cm^3 = 4 x  10^{-1}  cm^3

Therefore,  4 x 10^{-3 dl will be 4 x  10^{-1}  cm^3
