Theo mixes cake batter and places it in the oven at 350°F for 45 minutes. Explain what type of reaction baking a cake represents in terms of energy.
Answer:
Baking a cake requires heat to be applied to the batter in order for it to cook and chemically change into cake. The energy or heat applied is absorbed by the ingredients, so this represents an endothermic reaction.
Explanation:
that's the sample answer, hope it helps
The batter needs to be heated in order to cook and chemically transform into a cake when it is baked. An endothermic reaction is taking place because the energy or heat applied is being absorbed by the constituents.
What is energy?The quantitative characteristic that is transferred to a body or a physical system in physics is referred to as energy. It manifests itself as heat and light, as well as the act of doing work. Energy is a resource that is conserved; it can only be changed from one form to another and cannot be created or destroyed, according to the law of conservation of energy. The SI unit of energy measurement is the joule (J).
According to the question, there are various types of reactions two of which are endothermic reactions and exothermic reactions.
In an endothermic lot of energy is absorbed and in opposition to the exothermic reaction lot of energy is released.

What is 1.0147 rounded to the nearest thousandths place?
Answer:
1.0147 rounded to the nearest thousandths place is 1.015
Answer:
1.015
Explanation:
If you put the number in place value, you have 1 in the ones place, 0 in the tenths place, 1 in the hundreds place, 4 in the thousandths place, and 7 in the ten thousandths place. In order to know how to round 4, you must look at the number directly after it. Since 7 is greater than five, round up to ten. This increases 4 by 1 which would give you the answer 1.015.

Imagine that Yusef had a diet with absolutely no fat. What impact would this have on his overall health?
OPTIONS:
A.
He would have absolutely no energy.
B.
He would more easily absorb nutrients.
C.
He would be unable to absorb vitamins.
D.
He would have a compromised immune system.
PLEASE NO LINKS
Answer:
A.
Explanation:
In addition to helping you lose weight by using calories on more filling foods, following a low-fat diet can help you ward off serious medical conditions, including heart disease, high cholesterol, and diabetes. The body needs some fat to function properly.
If Yusef had a diet with absolutely no fat then He would have absolutely no energy. Hence A is correct option.
What fat do to your body?Fat aids in the body's absorption of vitamins A, D, and E. These vitamins are only absorbed with the aid of lipids because they are fat-soluble. Body fat is created from any fat that is not utilized by the body's cells or transformed into energy.
According to research, the majority of fat cells in adipose tissue are produced by cells that line the blood vessels. This realization might inspire fresh methods for treating and preventing obesity. Our metabolism, reproduction, and life lengths are all regulated by white adiposity, or fat, tissue.
Hence option A is correct.

Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.
Explanation:
have a beautiful day ahead
Magnetic fields can be mapped out using small plotting compasses : place the plotting compass near the magnet on a piece of paper. move the plotting compass to many different positions in the magnetic field, marking the needle direction each time. join the points to show the field lines.

Measure a pencil, end to end. Draw a sketch of the pencil and show your measurements. If you were to balance the pencil horizontally on your finger, where do you think it would be balanced? Note this on your sketch, and write down your hypothesis (distance from each end) and your prediction.
Now test your hypothesis. Balance the pencil on your finger horizontally. When it is balanced, your finger is at the center of gravity. Note and make a mark where your finger is in relation to each end of the pencil.
Measure from one end of the pencil to where your finger balanced it. Show this on your sketch, and record the data it in your chart.
Repeat steps b-c a second time for the pencil.
Repeat steps a - d using a pen and crayon as well.
What are your results? Compare your results with your hypothesis and then write an explanation in a conclusion. Which item has a center of gravity closer to the actual center that you measure?
Answer:
my pencil is about and 1/2 inches
i think it would be in the middle about 1 inch away

Explanation:
How does that motion change for the object if the forces on the object are unbalanced?
When the forces on the object are unbalanced, the object will move in the direction of the greater force.
What is Newton's first law of motion?Newton's first law of motion states that an object at rest or uniform motion in a straight line will continue in that path unless acted upon by an external force and the object will tend to move in the direction of the applied force.
What is Newton's second law of motion?Newton's second law of motion states that the force applied to a body is directly proportional to the acceleration of the body.
F = ma
Unbalanced forces on a bodyIf the net force acting on a body is greater than zero, the body will tend to move in the direction of the greater force.
Thus, when the forces on the object are unbalanced, the object will move in the direction of the greater force.

an audi car advertisement states its car can accelerate from a starting velocity of rest to an ending velocity of 70m/s in 35 seconds. what is the car acceleration?
Answer:
279 m/s
Explanation:
Answer:
2m/s^2
Explanation:
A=(u-v)/t
where u=final velocity and v=initial velocity and t=time
therefore u =70 and v=0 because the question said velocity of rest and finally t=35
so, (70-0)/35= 70/35=2

a box has a length of .5 m and a width of .1m. if the box exerts a force of 10 N on the floor, what is the pressure of the box on the floor
Answer:
The pressure of the box on the floor is 200 Pa
Explanation:
Given,
Length of the box=0.5m
Width of the box= 0.1m
∴Area of the box, A= (0.5 X 0.1) sq.m
= 0.05 sq.m
We know,
Pressure, P= F/A
= 10/0.05 Pa
= 200 Pa
∴The pressure of the box on the floor is 200 Pa
