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.

Answer:
Yes
Explanation:
The truck has momentum since it is moving and momentum is a product of mass and velocity. After impact, part of momentum that the truck had is transferred to the car hence the car initially at rest moves a significant diatance. Here, we utilize the formula MV= (m+M)v where M and V represent mass and velocity of the truck while m is the mass of car, v is the common velocity. Note that some letters are capital while others small, don't confuse these.
Given: Length of rod (L) = 80 cm
Weight of rod (W) =2.0 N
From the attached pictorial diagram,
XY = 80 cm,,XC = 40 cm, XA = 20 cm, AC = 20 cm
Let AB = z cm
Apply the principle of moment about the thread,
5.0 N × AX = (6.0 N × AB) + (2.0 N ×AC)
or, 5.0 N × 20 cm = (6.0 N × z cm) + (2.0 N ×20 cm)
or. AB = z = 10 cm
Now, distance XB = XA + AB = 20 cm + 10 cm = 30 cm
Hence, 6.0 N weight should be suspended from X end at distance of 30 cm
6.0 N weight must be placed 0.30 meters (or 30 cm) from end X to keep the rod in equilibrium.
To find the distance of the 6.0 N weight from end X that will keep the rod in equilibrium, you can use the principle of moments (also known as the law of torques). In equilibrium, the sum of the clockwise moments (torques) must be equal to the sum of the counterclockwise moments (torques).
Let's consider the moments (torques) about the point where the rod is suspended:
The 2.0 N weight (the rod's weight) is acting at the midpoint of the rod, which is 40 cm from the suspension point. The moment due to this weight is 2.0 N * 0.40 m = 0.80 N·m in the counterclockwise direction.
The 5.0 N weight at end X is acting at a distance of 20 cm (0.20 m) from the suspension point. The moment due to this weight is 5.0 N * 0.20 m = 1.00 N·m in the counterclockwise direction.
The 6.0 N weight hanging on the rod at an unknown distance "d" from end X creates a moment in the clockwise direction. So, the moment due to this weight is 6.0 N * d m in the clockwise direction.
In equilibrium, the sum of the counterclockwise moments must equal the sum of the clockwise moments:
0.80 N·m + 1.00 N·m = 6.0 N * d m
Now, solve for "d":
1.80 N·m = 6.0 N * d m
Divide both sides by 6.0 N:
d m = 1.80 N·m / 6.0 N = 0.30 m
So, the 6.0 N weight must be placed 0.30 meters (or 30 cm) from end X to keep the rod in equilibrium.
