Answer:
Is a Series Circuit
Explanation:
The circuit shown in the image is a series circuit, is considered as a closed circuit meaning that only has one path for the current to flow with all light bulbs in a row, the voltage applied to the circuit is equal to each voltage drop in the light bulb, if any light bulbs blow out, the current will not flow because the circuit is broken and the remaining light bulb would turn off.
Answer:
no because the car is in the rest so this not a acceleration
Answer:
D. Test a cell phone's reception in the exact same location under various atmospheric conditions
Explanation:
Components of an experiment:
Independent variable:
A manipulated variable, in an experiment or study, whose presence or degree incurs a change in the dependent variable.
Dependent variable:
A variable which is being studied in the experiment and is supposed to change with respect to the independent variable.
Control variable:
Control variable includes the variables which are of no concern in the experiment and must be constant so that they do not interfere with the results of the experiment. Change in control variable might affect the results of an experiment.
In Anna's experiment, the independent variable is the atmospheric conditions. The dependent variable is cell phone reception that will change according to the atmospheric conditions. All other things related to the experiment are control variables like cellphone, location of the cell phone. Both of these must stay constant to collect the best data.
Hence, the best option is D.
B. A safe landing on the station on earth
hope this helps :D
to get weight multiply Mass by 9.8
weight =9.8x15=147N
