Answer:
It's the last graph D.
Explanation:
A student builds a series circuit with four 1.5-volt batteries, a 5-ohm resistor, and two 1-ohm resistors. What is the total resistance in the circuit, and what is the value of its current?
(no explanation needed, i just need the answers)
Answer: The total resistance in the circuit is 7 ohms.
The value of the current in the circuit is 0.21 amperes.
there no explanation comment for other questions (:

Heat always moves from warmer objects to cooler objects.
True
False
Answer:
True
Explanation:
It's a basic law of science, that heat moves from a warmer object to a colder object. For example:
- hotter air moving into ice cube, making it melt
- hot iron warmth moving from iron to the air, slowly cooling down the iron.
I believe that's true but I could be wrong
Which one is goes with the option below Radiation Convection or Conduction.
Melting of a snowman
Answer:
It's definitely convection
Which of these statements best represents the law of conservation of energy?
A: Potential energy can be completely converted to kinetic energy.
B: The total energy in a system decreases over time.
C: Energy is being created in the universe every day
D: The energy created by machines can be lost.
A student builds a series circuit using three 1-ohm resistors. The current in the circuit is 1.5 amps. What is the voltage drop across each resistor?
(no explanation is needed! i just need the answer)
ANSWER:
Charge flows together through the external circuit at a rate that is everywhere the same. The current is no greater at one location as it is at another location. The actual amount of current varies inversely with the amount of overall resistance. There is a clear relationship between the resistance of the individual resistors and the overall resistance of the collection of resistors. As far as the battery that is pumping the charge is concerned, the presence of two 6-Ω ;resistors in series would be equivalent to having one 12-Ω resistor in the circuit. The presence of three 6-Ω resistors in series would be equivalent to having one 18-Ω resistor in the circuit. And the presence of four 6-Ω resistors in series would be equivalent to having one 24-Ω resistor in the circuit.

The three vehicles shown below are driving down the street at a constant velocity of 5 m/s. The blue car has a mass of 700 kg. The red car has a mass of 1800 kg. The silver pickup truck has a mass of 3500 kg. Annie-Drew wants to make a line graph showing the relationship between the kinetic energy and mass of the cars traveling at a constant velocity. What would the graph look like? Pls pick one of the line pictures and be specific.

the others make no sense
How will the total energy change as the car moves from point A to B to C? Assume that none of the energy is lost as friction or heat energy.
A The total energy will increase as the kinetic changes to potential and back again.
B Kinetic energy will change into potential energy and back again, but the total energy will stay the same.
C The total energy will decrease because the potential energy will change into kinetic energy.
D The total energy will decrease since it is losing potential energy at point E.
