Which statement best define percent error? check all that apply.
Art [367]

Percent error is the difference between the experimental value and theoretical value and measures the accuracy of the result found. The larger the error, lesser is the accuracy and vice versa.

Solution:

It is a mathematical way of showing accuracy

The higher the percent error, the less accurate the data set,

What is the definition of reflection of light?​
Savatey [412]

Answer: Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves.

the moon revolves around the earth in a nearly circular orbit kept by gravitational force exerted by the earth work done will be
rodikova [14]

Answer:

Zero because the applied force is perpendicular to the motion of the object.

No work is done on an object moving is a circular path about a central attractive force.

Any work done in such a case would result in a change in the orbit.

At any angular speed, a certain uniform solid sphere of diameter D has half as much rotational kinetic energy as a certain unifo
Trava [24]

Answer:

d. 6/5 M.

Explanation:

let the angular velocity =  \omega

the radius of sphere (r) = \frac{D}{2}

moment of inertia of solid sphere I_s = 2/5 M(\frac{D}{2})^2

rotational K.E of solid sphere= \frac{1}{2}* I_s* \omega ^2

=  \frac{1}{2} * 2/5 M(\frac{D}{2})^2 * \omega^2

we represent the mass of hallow sphere= M_{hs}

moment of inertia of solid sphereI_{ss} = 2/3 M_{hs}(\frac{D}{2})^2

rotational K.E of hollow sphere= \frac{1}{2}* I_{ss} * \omega^2

= 1/2 *2/3 M_{hs}(\frac{D}{2})^2* \omega^2

NOW,the kinetic energy of solid sphere= 1/2 kinetic energy of hallow sphere

=1/2 [2/5 M(D/2)^2 ]\omega^2= 1/2 (1/2 (2/3 M_{hs}(D/2)^2 )\omega^2 }

2/5M= 1/3 M_{hs}

M_{hs} = 3(2/5M)

M_{hs} = 6/5 M
