Oil is a powerful source of energy used for cars, machines, and many other purposes. While studying sources of energy that could replace the use of oil, a student thinks about solar power, wind power, nuclear power, and electric batteries. The students asks,"Which type of source will waste the least energy and provide the most energy in all situations?"
Which best describes why a scientist would ask a different question than this one?
O The question asks about subjective personal preferences regarding energy.
O The question focuses on the objective measurements of amounts of energy.
O The question has too wide of a focus, as though all situations can be studied at once.
O The question is focused on the future and finding new answers about changing needs.
Answers
Answer:
C
Explanation:
scientists usually focus on one specific problem, rather than a whole range. so the answer would be that it's too wide a focus.

At which type of boundary do lithospheric plates collide?
This is Earth science
Answers
Answer:
convergent boundary
Explanation:
A convergent boundary is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other causing a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone.
hope this help
2. what happens to a convergent boundary?
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.

What is the other-feeders and self-feeders for paramecia?
Write your response below
Answers
Answer:
Paramecium (also Paramoecium, is a genus of unicellular ciliates, commonly studied as a representative of the ciliate group. Paramecia are widespread in freshwater, brackish, and marine environments and are often very abundant in stagnant basins and ponds. Because some species are readily cultivated and easily induced to conjugate and divide, it has been widely used in classrooms and laboratories to study biological processes. Its usefulness as a model organism has caused one ciliate researcher to characterize it as the "white rat" of the phylum Ciliophora

A graph titled Position versus time for 2 cars with horizontal axis time (seconds) and vertical axis position (meters). An orange line labeled A has a sharp upward slope. A blue line B has a slight downward slope. Which statements best describe the motion of Car A and Car B? Check all that apply. Car A and Car B are both moving toward the origin. Car A and Car B are moving in opposite directions. Car A is moving faster than Car B. Car A and Car B started at the same location. Car A and Car B pass each other at the crossover point on the graph.
Answers
Answer:
B- Car A and Car B are moving in opposite directions.
C- Car A is moving faster than Car B.
E- Car A and Car B pass each other at the crossover point on the graph.
The statements best describe the motion of Car A and Car B are Car A and Car B are moving in opposite directions, Car A is moving faster than Car B, Car A and Car B pass each other at the crossover point on the graph. Therefore, option B, C and E are correct.
What do you mean by motion of car ?Periodic motion is a type of motion in which the body follows the same path over and over again. In the preceding question, we are told that vehicles travel on a straight road. So, the motion it performs is rectilinear.
The frictional force between the road and the tire causes the tire to "push" off the road, propelling the car forward.
Motion is defined as a change in position over time or with respect to a fixed point. If we are sitting in a moving car, we are moving to someone outside the car.
Thus, option B, C and E are correct.

One reactant and one product needs the coefficient 2.
The products both need a 3 coefficient.
The reactants both need a 2 coefficient.
Atoms in the equation are already in balance.

The statement that best explains how to balance the equation: ZnSO4 + Li2CO3 → ZnCO3 + Li2SO4 is: atoms in the equation are already in balance.
HOW TO BALANCE A CHEMICAL EQUATION:
A chemical equation is said to be balanced if the number of atoms of each element in the reactant side is equal to that on the product side.In the equation given in this question as follows:
ZnSO4 + Li2CO3 → ZnCO3 + Li2SO4
There are:1 atom of Zn on both sides of the equation1 atom of sulfur on both sides of the equation7 atoms of oxygen on both sides of the equation2 atoms of lithium on both sides of the equation. Since the number of atoms of each element on both sides of the equation are the same, hence, the equation is said to be balanced.
