Describe the general relationship between the weight of adult men and the average number of Calories needed daily to maintain a steady weight.
Answer:
The average number of calories needed daily represents the average quantity of calories eliminated by human body due to metabolism and must be compensated by eating and drinking.
The amount of calories contained in the food we eat every day must represent the amount of calories eliminated by the body in that time to have a steady weight.
Explanation:
The average number of calories needed daily represents the average quantity of calories eliminated by human body due to metabolism and must be compensated by eating and drinking. If total quantity of calories in the food we consume every day is higher that the average number of calories needed daily, then weight increases by fat accumulation.

If two lines in a system of linear equations have the same slope and same y-intercept, how many solutions will the system have?
Answer:
We will have infinite solutions to the system of linear equations.
Explanation:
Well, when we have two lines with the same slopes and the same y-interception, both of them are overlapped, so we will have infinite solutions to the system of linear equations.
This kind of system is called dependent system.

An iron atom (Fe) has 26 protons in it. If the atom has 20 electrons in it, explain what type of charge it has and how you can tell.
Answer:
The iron atom has a positive charge, making it a cation.
Explanation:
The atom has a nucleus, where the protons and neutrons, which are the subatomic particles with the highest mass, are located. Practically all the mass of the atom is concentrated in the nucleus.Protons have a positive electrical charge, while neutrons have no charge.
Electrons move around the nucleus with other negatively charged particles.
An iron atom (Fe) has 26 protons and 20 electrons in it. That is, there are 6 more protons than electrons. As mentioned, protons are positively charged. So the iron atom has a positive charge, making it a cation.

Researchers have found that the larvae of all North American firefly species glow as a warning sign to ward off predators. However, the presence and use of lighting organs in adult fireflies vary greatly. Some species use glowing or light flashes as mating signals, while other species produce pheromones as mating signals and do not glow at all. Discuss how the physical characteristics and mating behavior of North American fireflies support the theory of speciation. In your discussion, provide a hypothesis to explain the driving force behind the differences in mating signals among the species.
Explanation:
The theory of speciation confirms what happens with fireflies, only fireflies that are part of the same species can reproduce among themselves, which means that fireflies that use pheromones as mating signals will attract fireflies that use that same form or mechanism of reproduction.
Some mechanisms that allow this type of differentiation or speciation to occur are: seasonal or geographic isolation and sexual isolation due to behavior or conduct.
Speciation allows the formation of new populations of organisms that share the same physiological and genetic characteristics. Therefore, the adult fireflies that shine as a mating signal are possibly found in the same geographical position and their physiological and genetic characteristics are compatible with those of his own species.
A sphere of mass m1 is attached to an ideal spring, then pulled downward from its equilibrium position and released from rest. A sphere of mass m2 is hung from a massless string of length L, pulled to the right from its equilibrium position, and released from rest. If both spheres have the same period of oscillation, then what is the spring constant of the spring attached to m1
Answer:
k = [tex]\frac{g \ m_1}{L}[/tex]
Explanation:
In this exercise the two cases presented are a simple harmonic motion, with angular velocity
spring - mass w² = k / m₁
simple pendulum (string- mass m₂) w² = g / L
angular velocity and period are related
w = 2π/ T
since they indicate that the two periods are equal, the angular velocities are also equal, therefore we can equal the two equations
[tex]\frac{k}{m1} = \frac{g}{L}[/tex]
k = [tex]\frac{g \ m_1}{L}[/tex]

Water rockets are very different from fuel powered rockets for many reasons. Explain some of the differences between them and why rockets that are launched into space require more power and thrust that water rockets?
Answer:
How is a water rocket different than a compressed air rocket?
Usually the rocket is made from a 2-liter soda pop bottle. Before launch, the bottle is filled with some amount of water, which acts as the "propellant" for the launch. Since water is about 100 times heavier than air, the expelled water produces more thrust than compressed air alone.

If there is a negative sign in front of the Hooke's Law equation, what does the force, F, represent?
Answer:
Hooke's law, given by [tex]F=-kx[/tex] is denoted with a negative sign to regard that the direction of restoring force that occurs opposite in direction of the force that caused the displacement [tex]x[/tex]. F represents the force required to create a spring displacement of [tex]x[/tex].
Explanation:
As with many things in physics, the negative sign represents direction. In this case, after a spring is displaced a distance of [tex]x[/tex] from equilibrium, the restoring force created by the spring will be in opposite direction of the force applied to move the spring there, represented by F.

Pam is running in a race at 3.3 m/s and accelerates at a rate of 3 m/s for the last 15 meters. How fast is she running when she crosses the finish line?
Answer:
Pam's velocity when she crosses the finish line is 10 m/s.
Explanation:
Given;
initial velocity of Pam, u = 3.3 m/s
acceleration of Pam, a = 3 m/s²
last distance covered, d = 15 m
let her final velocity = v
Apply the following kinematic equation to determine Pam's final velocity;
v² = u² + 2ad
v² = 3.3² + 2(3)(15)
v² = 10.89 + 90
v² = 100.89
v = √100.89
v = 10 m/s
Therefore, Pam's velocity when she crosses the finish line is 10 m/s.
Find the current flowing out of the battery.
Answer:
0.36 A.
Explanation:
We'll begin by calculating the equivalent resistance between 35 Ω and 20 Ω resistor. This is illustrated below:
Resistor 1 (R₁) = 35 Ω
Resistor 2 (R₂) = 20 Ω
Equivalent Resistance (Rₑq) =?
Since, the two resistors are in parallel connections, their equivalence can be obtained as follow:
Rₑq = (R₁ × R₂) / (R₁ + R₂)
Rₑq = (35 × 20) / (35 + 20)
Rₑq = 700 / 55
Rₑq = 12.73 Ω
Next, we shall determine the total resistance in the circuit. This can be obtained as follow:
Equivalent resistance between 35 Ω and 20 Ω (Rₑq) = 12.73 Ω
Resistor 3 (R₃) = 15 Ω
Total resistance (R) in the circuit =?
R = Rₑq + R₃ (they are in series connection)
R = 12.73 + 15
R = 27.73 Ω
Finally, we shall determine the current. This can be obtained as follow:
Total resistance (R) = 27.73 Ω
Voltage (V) = 10 V
Current (I) =?
V = IR
10 = I × 27.73
Divide both side by 27.73
I = 10 / 27.73
I = 0.36 A
Therefore, the current is 0.36 A.

According to the law of universal gravitation, any two objects are attracted to each other. The strength of the gravitational force depends on the masses of the objects and their distance from each other.
Many stars have planets around them. If there were no gravity attracting a planet to its star, the planet's motion would carry it away from the star. However, when this motion is balanced by the gravitational attraction to the star, the planet orbits the star.
Two solar systems each have a planet the same distance from the star. The planets have the same mass, but Planet A orbits a more massive star than Planet B.
Which of the following statements is true about the planets?
A.
Planet B will keep orbiting its star longer than Planet A.
B.
Planet B is more attracted to its star than Planet A.
C.
Planet A orbits its star faster than Planet B.
D.
Planet A has a longer year than Planet B.
C. Planet A orbits its star faster than Planet B.
Explanation:
since Planet A is closer to the star due to its gravitational force, it will orbit its star faster than planet B
