B. Both physical and chemical changes occur when you make pizza from scratch.
C. Only chemical changes occur when you cook a frozen pizza and only physical changes occur when you make pizza from scratch.
D. You cause chemical changes in vegetables by cutting them into small pieces
Both physical and chemical changes occur when you make pizza from scratch.
The correct statement from the given options is: Both physical and chemical changes occur when you make pizza from scratch. When you make pizza from scratch, physical changes occur when you mix and shape the ingredients, while chemical changes occur during the process of baking the pizza dough and melting the cheese. These changes involve the breaking and forming of chemical bonds, resulting in the creation of new substances with different properties.
Additionally, cheese undergoes a chemical change as it melts, proteins denature, and Maillard reactions occur, resulting in the development of new flavors and textures.
Thus, making pizza from scratch is a dynamic process that encompasses both physical and chemical changes, highlighting the fascinating chemistry and physics behind this delicious culinary endeavor.

fulcrum to get the correct mechanical advantage?
Answer:
The distance of load from fulcrum is 5 m.
Explanation:
Given:
Mechanical advantage, MA = 0.4
Distance of force from fulcrum is,
Distance of load from fulcrum is,
We know that, Mechanical advantage of a machine is the ratio of the effort arm and load arm.
So, Mechanical advantage is given as:
Therefore, the distance of load from fulcrum is 5 m.
when was slate found
It was one of the earliest times the concept of crustal motion had been presented to the scientific world, and it lay the foundation for the creation of current plate tectonics, even if Wegener's "continental drift" hypothesis was eventually refuted.
In order to comprehend mountain-building processes, volcanic eruptions, earthquakes, the evolution of the Earth's surface, and rebuild the continents and oceans that once covered it, plate tectonics, a theory about the dynamics of the lithosphere, revolutionized Earth sciences.
In the 1960s, the theory of tectonics was developed. The lithosphere, which really is typically 100 km thick and sits on top of the asthenosphere, a plastic layer, is said to be Earth's outermost, unyielding layer.
The lithosphere is divided into several small plates, six to eight medium-sized local plates, and seven extremely massive continental and oceanic plates.

The speed of the ball is 27.4 m/s
Explanation:
The speed of an object is given by:
where
d is the distance covered
t is the time taken
In this problem, we have:
d = 300 yards is the distance covered by the golf ball
t = 10 s is the time taken
Keeping in mind that
1 yard = 0.914 m
We can convert the distance from yards to meters:
And substituting into the equation, we find the speed of the ball:

330 m
990 m
0.5 m
Answer:
The wavelength of the sound wave traveling at 330 m/s is 0.5 m.
Explanation:
Given:
Speed of sound wave is,
Frequency of the sound wave is,
Speed of a sound wave is related to its frequency and wavelength as:
, where, is the wavelength.
Now, plug in 330 for , 660 for and solve for . This gives,
Therefore, the wavelength of the sound wave traveling at 330 m/s is 0.5 m.
