Answer:
88N
Explanation:
If the force of gravity acting on the box is 88N, then the normal force on the box is also 88N;
The force of gravity is the vertical pull of gravity on a body.
The normal force is the force a surface impresses on an object to prevent it from passing through.The normal force is equal to the gravitational force pull on a body.
So the solution is 88N

Which idea did Ptolemy’s model use to explain why the planets appeared to move backward as they moved in their orbits?
The planets spun in epicycles.
The planets rotated on their axes.
The planets revolved around the Sun.
The planets were made of different materials.
Answer:
The planets spun in epicycles.
Explanation:
Ptolemy's model used to explain that the planets spun in epicycles.
What is Ptolemy's model? How it was explained?
Ptolemy placed the Earth at the center of the geocentric model. The system of planetary motions according to which the earth is at the center with the sun, moon, and planets revolving around it and each orbit except for the sun and moon is composed of a principal circle upon which moves a smaller circle carrying the planet. As he knows about the planetary motions and ideas about the universe was a set of spheres that surrounds the earth. He also believed that the moon has the orbit which is closest to the earth, the Mercury , the Venus and the sun.
According to Ptolemy he considered and mentioned completely about 48 constellations.
Hence, Option A is the correct answer.

Neutral atoms of oxygen with a mass of 15 are frequently used in brain imaging technology. Could the atom symbol below be used in this process? Why or why not?
Answer: No, because the atomic number shown in the symbol (Z = 15) is not the atomic number of oxygen (Z = 8)
Explanation:
When we have an atom, the number in the top left is the mass number A, is equal to the sum between the number of neutrons and protons in the atom.
In this case, between protons and neutrons, we have 32.
The number at the bottom left is the atomic number Z, which is equal to the number of protons in the atom.
Particularly, this number is different for every element. For example, for the oxygen we would have Z = 8, this means that the oxygen has 8 protons.
In the image, we can see Z = 15, then the atom has 15 protons, this means that it can not be oxygen (Z = 15 is for phosphorus, then this atom would be phosphorrs). Then the symbol can not be used, because that is not oxygen.

Which is a possible result of rising ocean temperatures caused by global warming?
formation of dust bowls
increase in strength of hurricanes
rapid evaporation of water in soil
decrease in population due to health threats
Answer:
Increase in strength of hurricanes
Explanation:
A possible result of rising ocean temperatures caused by global warming is increase in strength of hurricanes.
What is global warming?Global warming is an environmental concern characterized by the gradual increase in the Earth's atmospheric temperature.
Global warming can lead to the rise of temperature in air and oceans as well.
One consequence of an increase in ocean temperature is that the strength of hurricanes, which is strong wind accompanied by rain, will be increased.
Therefore, a possible result of rising ocean temperatures caused by global warming is increase in strength of hurricanes.

Look at photo D. Explain how the fountains help to keep the gardens cool.
Answer with Explanation:
Spain is known to have hot summers, thus, it is very easy for water to evaporate once exposed to direct heat source (such as the sun).
A fountain is being used in order to keep the garden's surrounding air temperature low by allowing the evaporation of water. One factor that speeds up the evaporation of water is the surface area. The water coming out of a fountain is in small quantities; however, it meets up with hot air in a large surface area. This allows faster evaporation, leading to an even greater cooling effect because heat is being transported immediately from the liquid state to the gaseous state. This is the reason why people often meet up in places where there's a fountain. It is not only aesthetically appealing but also provides comfort from the heat.

What is the acceleration for an object moving with constant speed? Explain your answer
Answer:
What is the acceleration of an object moving at a constant speed?
The Meaning of Constant Acceleration
The data table above show an object changing its velocity by 10 m/s in each consecutive second. This is referred to as a constant acceleration since the velocity is changing by a constant amount each second.
Answer:
there is no acceleration for an object moving with constant speed
Explanation:
it is because acceleration is change in velocity and constant means same or without any change so there is no acceleration for an object which is moving with same speed

Determine the gradient of a slope that starts at an elevation of 85 meters and ends 15 km away at an elevation of 10 m.
Answer:
Explanation:
To calculate the gradient we can use the equation for it, which is:
change in field value / distance = gradient
Since we already know the values, we can directly go with the calculation. The change in field value is 55 m - 15 m = 40 m, and we will need to convert the 20 km into meters, so we will have 20,000 m.
40 / 20,000 = 0.002
So the gradient of the suggest slope will be only symbolic 0.002 degrees.
For questions A, B, C, and D. Determine if the Kinetic Energy will increase, decrease or stay the same based on the directions of their force and velocity vectors.
Explanation:
KE = 1/2*m*v^2
mass won't change
but velocity is
A: the force is pushing against the direction of the object, so velocity is decreasing, so KE is decreasing
B: the F net line is pretty much straight up, which means there is no net force pushing to the left, but velocity is still increasing
Why? Because if you use the pythagorean theorem, the hypotenuse is always longer than the legs.
Note: velocity only ever stays the same if there is no net force (or 0 acceleration), so all four of these are either decreasing or increasing
C: there is a net force to the right, so velocity is increasing
D: There is a net force to the right but velocity is to the left, so velocity is decreasing
Hope I got these right

What is the relationship between Earth’s mass and its atmosphere?
Answer:
Mass is proportional to gravity and gravity is necessary to hold an atmosphere, therefore mass would seem to be very important for the ability for a body to have an atmosphere. However there are quite a few examples that show that it doesn't require that much mass to get an atmosphere.
Explanation:
Answer + Explanation : Mass is proportional to gravity and gravity is necessary to hold an atmosphere, therefore mass would seem to be very important for the ability for a body to have an atmosphere.

mass (m):
200 N = m (3.5 %)
Answer:
5714.29
Explanation:
The given expression is:
200 = m(3.5% )
To solve this problem, we use the concept of multiplicative inverse;
The multiplicative inverse involves using the reciprocal of 3.5% to multiply both side of the expression;
200 = m x [tex]\frac{3.5}{100}[/tex]
m = [tex]\frac{100}{3.5}[/tex] x 200 = 5714.29
