Answer:
B. Voltage
Explanation:
Ohm's law: current times resistance equals voltage.
V = IR
If you are being tailgated and need to make a stop, you should:
B. flash your brake lights ahead of time.
C. slow sooner to make a gradual stop.
<h3>What is tailgating?</h3>
Tailgating can be defined as an act which typically involves a tailgater driving dangerously close behind another vehicle that is in front.
This ultimately implies that, a tailgating vehicle is a hazard to any driver because when he or she brakes suddenly, it may result in the tailgater hitting him or her from the rear.
In this context, we can infer and logically deduce that if you are being tailgated and need to make a stop, you should flash your brake lights ahead of time and slow sooner to make a gradual stop.

Answer:
I think the answer is B. Black
Answer:
A complex system is a system composed of many components which may interact with each other.
ADVANTAGES
Structs are marginally faster at runtime than classes, due to optimisations done by the compiler. You can enforce full immutability. If you declare a struct instance as let, you will not be able to change its properties.
DISADVANTAGES
A complex corporate structure makes communication more difficult. For instance, when workers must interact with several supervisors, the various directives might work at cross purposes. Also, messages might get lost in the shuffle if there is no simple way to communicate within the organization.
Answer:
Mass of earth will be 
Explanation:
We have given acceleration due to gravity 
Radius of earth = 6370 km =
Gravitational constant 
We know that acceleration due to gravity is given by
, here G is gravitational constant, M is mass of earth and R is radius of earth
So 
So mass of earth will be
