Answer:
bears = {"Grizzly":"angry", "Brown":"friendly", "Polar":"friendly"}
for bear in bears:
if bears[bear] == "friendly":
print("Hello, "+bear+" bear!")
else:
print("odd")
Explanation:
A dictionary called bears is given. A dictionary consists of key-value pairs.
You need to check each key-value pairs in bears and find the ones that have "friendly" as value using a for loop and if-else structure. In order to access the values of the dictionary, use the dictionary name and the key (inside the loop, the key is represented as bear variable). If a key has a value of "friendly", print the greeting. Otherwise, print "odd".
Answer: Information
Explanation: Information flows consist of data related to demand, shipments, orders, returns, and schedules, as well as changes in any of these data.
Answer:
great enough to overcome.
Explanation:
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
Where, K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
A conductor can be defined as any material or object that allows the free flow of current or electrons (charge) in one or more directions in an electrical circuit. Some examples of a conductor are metals, copper, aluminum, graphite, etc.
When heating a substance, a phase change will start to occur when the kinetic energy of the particles is great enough to overcome the attractive forces between the particles.
Basically, the phase change includes solid, liquid and gas.
The correct answer is C. The split phase motor has two windings on the stator.
A split phase AC induction motor runs on a single phase and splits the phase into two windings, a run winding, and a start winding, on the stator. The start winding axes is 90 degrees electrically to the run winding. This helps to produce a rotating magnetic field at startup and gets the motor spinning. This secondary 'start' winding on the stator is a key feature of split phase motors.
