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.

Continental Drift Research HW(12 Sentences)
Answer:
Here it is lol
Explanation:
Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have 'drifted' across the ocean bed. The theory of continental drift is most associated with the scientist Alfred Wegener. In the early 20th century, Wegener published a paper explaining his assumption that the continental landmasses were drifting across the planet, sometimes plowing through oceans and into each other. He called this movement Continental drift. Many people did not believe the theory and he received criticism for it because it was incomplete and flawed, and he could not fully explain what drove the continental drift to occur. You can best see this in the quote by Geologist R. Thomas Chamberlain. “If we are to believe in Wegener’s hypothesis we must forget everything which has been learned in the past 70 years and start all over again.”The idea of Continental drift includes the theory of plate tectonics, which explains the cause of the continents drifting. The earth’s outer shell composed of plates moves a little bit every year. The heat coming from the interior of the earth triggers this movement to occur through convection currents inside the mantle. And that all of the Earth's continents were once part of an enormous, single landmass called Pangaea.
As part of his hypothesis of a mega continent, he discovered research papers on fossils supporting his theory that Africa and South America had once been connected. These studies indicated evidence of fossils of identical land animals that had lived in both areas simultaneously hundreds of millions of years ago. One fossilized land organism that added credibility to Wegener’s theory was that of the Mesosaurus, a small, freshwater aquatic reptile from the Permian period about 260 million years ago in what is now Easternsouth America and Southwestern Africa. Wegener asserted that South America and Africa must have been joined during that period of history because fossils of Mesosaurus are limited to those regions, and if Mesosaurus had been able to make the long journey across the South Atlantic, its fossils would likely be more widely distributed.

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.

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 sled drops 50 meters in height on a hill. The mass of the rider and sled is 70 kg and the sled is going 10 m/s at the bottom of the hill. What is the efficiency of energy conversion from potential to kinetic?
Answer:
Efficiency = 10.2 %
Explanation:
Given the following data;
Mass = 70 kg
Height = 50 m
Velocity = 10 m/s
We know that acceleration due to gravity is equal to 9.8 m/s².
To find the efficiency of energy conversion from potential to kinetic;
First of all, we would determine the potential energy;
P.E = mgh
P.E = 70 * 9.8 * 50
P.E = 34300 J
For the kinetic energy;
K.E = ½mv²
K.E = ½ * 70 * 10²
K.E = 35 * 100
K.E = 3500
Therefore, Input energy, I = 34300 J
Output energy, O = 3500 J
Next, we find the efficiency;
Efficiency = O/I * 100
Substituting into the formula, we have;
Efficiency = 3500/34300 * 100
Efficiency = 0.1020 * 100
Efficiency = 10.2 %
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.
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

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.

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.

A girl pushes her little brother on his sled with a force of 200. N for 850. m. How much work is this iſ the fored
of friction acting on the sled is (a) 200. N. (b) 300. N?
Explanation:
Given that,
A girl pushes her little brother on his sled with a force of 200. N for 850. m
We need to find the work done by the force of friction acting on the sled. The force of friction is 200 N
Net force = 200 N - 200 N = 0
Work done = 0
If force of friction is 300 N.
Net force = 300 N - 200 N = 100 N
The work done by a force is given by :
W = Fd
Put values,
W = 100 × 850
W = 85000 J
Hence, this is the required solution.
