Answer:
D
The toy car would travel farther because more potential energy would be transferred into kinetic energy
Explanation:
Increase in angle will lead to increase in height.
Since potential energy = mgh
Definitely potential energy will also increase.
According to conservative of energy, the maximum potential energy is equal to the maximum kinetic energy. Therefore, the toy car would travel farther because more potential energy would be transferred into kinetic energy.
Answer:
Validity
Explanation:
Validity or construct validity is the sufficiency of the operational meaning of factors.. It measures the extent to which the the operational meaning of a variable really mirrors the genuine hypothetical importance of the variable.
Validity alludes to how much deductions can authentically be produced using the operationalizations in your investigation to the hypothetical builds on which those operationalizations were made.
validity is identified with generalization.
Energy/power is not gained or lost going through a (ideal) transformer.
So the transformer in this problem really doesn't matter. If the lamp is using energy at the rate of 60 watts, then the whole contraption is getting 60 watts of power from the wall outlet.
Power = (voltage) x (current)
60 watts = (120 v) x (current)
Current = (60 watts) / (120 v)
<em>Current = 0.5 Ampere</em>
The tank can hold 0.0088 gallons of propane when filled to 60% of its capacity.
What is capacity?
The maximum output that a business can maintain while producing a good or offering a service is known as capacity. Management must acknowledge production process limitations in order to plan for capacity.
Capacity can refer to the a production process, the distribution of human resources, technical thresholds, or a number of other related ideas depending on the type of business. No system can sustain full operation for an extended period of time; delays and inefficiencies prevent long-term output from reaching a theoretical level.
The volume of a spherical propane tank can be calculated using the formula:
Volume = (4/3)*π*r^3
where r is the radius of the tank.
The radius of the tank is equal to half its diameter, which in this case is 4/2 = 2 cm.
Therefore, the volume of the tank is (4/3)*π*2^3 = 33.51 cubic centimeters.
Now, we can convert this volume to gallons. 1 gallon is equivalent to 3785.41 cubic centimeters.
Therefore, the number of gallons of propane the tank can hold is 33.51/3785.41 = 0.0088 gallons.
Finally, the tank can hold 0.0088 gallons of propane when filled to 60% of its capacity.
