No animations are applied when showing or hiding the content.

None

13.

To delay the start of an animation.

None

14.

What must be set to disable default animations in the parent AnimatedVisibility instance?

EnterTransition.None and ExitTransition.None

scaleIn() with a value of zero

tween() duration to zero

animationSpec to null

None

15.

What is the default alpha value for the fadeIn() function?

2.0

1.0

0.5

None

16.

Which of the following is a predefined animation easing option in Jetpack Compose?

None

17.

What does the expandVertically() animation effect do?

Expands the content into view vertically.

Shrinks the content vertically before disappearing.

Fades the content out of view.

Slides the content into view horizontally.

None

18.

What is the purpose of the targetState parameter in the Crossfade composable?

It sets the duration of the fade.

It specifies which composable should be visible.

It controls the size of the fade area.

It defines the background color of the fade.

None

19.

What is the role of the 'targetState' in MutableTransitionState?

It modifies the color of the animated component.

It adjusts the speed of the animation.

It determines the end state of the animation.

It sets the initial size of the animation.

None

20.

What does the expandIn() function do?

Fades content in without resizing it.

Reveals content using both horizontal and vertical clipping.

Shrinks content from view along both axes.

Crossfade()

tween()

animateContentSize()

expandVertically()

None

22.

When using AnimatedVisibility, how can you control the easing effect of an animation?

By adding a delay parameter to the animation.

By setting the visible parameter to true.

By using the fadeIn() function.

By passing an easing value to the tween() function.

None

23.

What does the tween() function allow you to do?

Modify the layout of a composable.

Control animation duration and easing.

Set a specific position for animations.

Repeat animations indefinitely.

None

24.

What is the purpose of the AnimatedVisibility composable in Jetpack Compose?

To perform animations on list scrolling behavior.

To create custom animations for any composable.

To adjust the padding of a composable.

To animate the visibility of a composable when it appears or disappears.

None

25.

What is the function of the 'enter' parameter in the AnimatedVisibility composable?
