a resistance of 60ohms allows 0.4 amps of current to flow when it is connected across a battery. what is the voltage of the battery?
Answer:
V = 24 [V]
Explanation:
To solve this problem we must use ohm's law, which tells us that the voltage is equal to the product of resistance by the current.
V = I*R
where:
V = voltage [V]
I = current [amp]
R = resistance [ohm]
Therefore:
V = 0.4*60
V = 24 [V]

A student wants to shorten the ripening time for tomatoes. He predicts that the more water the seedlings receive, the faster the tomatoes will ripen. He grows 20 tomato plants in a garden with full sunlight that has dry soil and 20 tomato plants in the same garden where there is more moisture in the soil. He records the time it takes for fruit to develop and ripen on the plants in each location. What is the test variable (independent variable) in this experiment?
Answer:
Moisture
Explanation:
The independent variable, in this case, would be the moisture levels of the soils.
The independent variable is the variable being tested. It is the only variable that is altered in the course of an experiment and which has a direct effect on the actual variable that is the main aim of the experiment. All other variables are kept constant while the independent variable is manipulated.
The tomato plants in the two groups were under the same conditions except that a group had more moisture in the soil. Hence, the independent variable is the moisture.

A car accelerates uniformly from rest to a speed of 6.6 m/s in 6.5 s. Find the acceleration the car presents during this time?
Answer:
1.02 m/s²
Explanation:
The following data were obtained from the question:
Initial velocity (u) = 0 m/s
Final velocity (v) = 6.6 m/s
Time (t) = 6.5 s
Acceleration (a) =.?
Acceleration can simply be defined as the change of velocity with time. Mathematically, it can be expressed as:
a = (v – u) / t
Where:
a is the acceleration.
v is the final velocity.
u is the initial velocity.
t is the time.
With the above formula, we can obtain the acceleration of the car as follow:
Initial velocity (u) = 0 m/s
Final velocity (v) = 6.6 m/s
Time (t) = 6.5 s
Acceleration (a) =.?
a = (v – u) / t
a = (6.6 – 0) / 6.5
a = 6.6 / 6.5
a = 1.02 m/s²
Therefore, the acceleration of the car is 1.02 m/s²

What forces are included on a free-body diagram for a chosen object?
a.all the forces exerted on or by the object.
b.all the forces exerted by the object, but not on it
c. all the forces exerted on the object, but not by it
d. all forces that exist within the neighborhood of the object
Answer:
C
Explanation:
A free-body diagram shows all the forces exerted or applied on an object.
A free-body diagram includes all the forces exerted on or by the object. Hence, option A is correct.
What is a free-body diagram?A free-body diagram is a diagrammatic representation of a single body or a group of bodies that are separated from their surroundings and display all the forces acting on them. A free-body diagram (FBD; sometimes known as a force diagram) is a graphical representation used in physics and engineering to show the applied forces, moments, and consequent reactions on a body under a specific condition.
It shows a body or group of connected bodies along with all the applied forces, times, and reactions that the body experiences. The body could be compact or comprise several interior pieces (like a truss) (such as a beam). To answer difficult problems, a series of free bodies and other diagrams may be required.
Hence, all the forces exerted on or by the object are included in the free-body diagram.

An object with a mass of 2kg accelerates 10m/s2 when an unknown force is applied to it, What is the amount of the force?
Answer: the awnser is 19k
Explanation:
Answer:
hope the answer helped you. pls mark as brainliest
Explanation:
Newton's second law states that the acceleration an object experiences due to a given force is inversely proportional to its mass, that is --
a=Fm
If the acceleration is 10m/s2 and the object's mass is 2kg , we can use Newton's second law to find that:
10m/s2=F2kg
F=20kg m/s2 , or 20N .
Molten (melted) iron and carbon monoxide are produced in a blast furnace by the reaction of iron(III) oxide and pure carbon. Fe2O3 + 3C ---> 2Fe + 3CO If 4 moles of Fe2O3 are used, how many moles of Carbon Monoxide (CO) can be produced?
Answer:
Explanation:
Fe₂O₃ + 3C ---> 2Fe + 3CO
1 mole 3 moles
From the balanced equation above , we see that , 1 mole of Fe₂O₃ reacts with carbon to form 3 moles of CO .
So , 4 moles of Fe₂O₃ will react with carbon to form 3 x 4 moles of CO .
moles of CO formed = 3 x 4 moles = 12 moles.

What is the best description of temperature?
Answer
An object's temperature is the best approximation of the kinetic energy of the particles. When we measure an object's temperature, we measure the average kinetic energy of the particles in the object. The higher the temperature, the faster the molecules of the substance move, on the average
The measure of the warmth or coldness of a substance or an object with reference to some standard value is termed as temperature.
TemperatureIt is a measure of the coldness or hotness expressed in terms of any of the many arbitrary scales and suggesting the direction in which the heat energy will flow spontaneously, that is, from a hotter body to a colder body.
Similar to pressure or density, temperature is an intensive property, which is independent of the quantity of matter being considered.
Thus, temperature refers to a physical quantity, which expresses the extent of coldness or hotness of a substance.

If a 3.1g ring is heated using 10.0 J, its temperature rises 19.7°C. Calculate
the specific heat capacity of the ring.
Answer:
Since 10 J / 4.19 J /cal = 2.39 cal is the heat absorbed by the ring
Q = Cs * m * (T2 - T1) heat absorbed by ring
Cs = 2.39 cal / (3.1 g * 19.7 deg C) = .039 cal / (gm deg C)
10 J / 4.19 J /cal = 2.39 cal is the heat absorbed by the ring, Q = Cs * m * (T2 - T1) heat absorbed by ring. Cs = 2.39 cal / (3.1 g * 19.7 deg C) = .039 cal / (gm deg C).
What is Specific heat capacity?The amount of heat required to raise the temperature per unit mass is known as specific heat capacity. The heat in Joules required to increase the temperature of 1 gram of sample by 1 Kelvin or degree Celsius is typically stated.
Water is an excellent temperature regulator because it has a very high specific heat capacity.
The amount of heat in joules needed to raise 1 gram of a substance by 1 Kelvin is known as the specific heat capacity (symbol: c). It could also be written as J/kgK. Molar heat capacity, measured in J/mol K, and volumetric heat capacity, measured in J/m3 K, are comparable values.
Therefore, 10 J / 4.19 J /cal = 2.39 cal is the heat absorbed by the ring, Q = Cs * m * (T2 - T1) heat absorbed by ring. Cs = 2.39 cal / (3.1 g * 19.7 deg C) = .039 cal / (gm deg C).
