Answer:
The correct answer is option 'c':Convection.
Explanation:
When we ignite a campfire the heat produced by combustion heats the air above the fire. As we know that if a gases gains heat it expands thus it's density decreases and hence it rises, if we hold our hands directly above the fire this rising hot air comes in contact with our hands thus warming them.
The situation is different if we are at some distance from the campfire laterally. Since the rising air cannot move laterally the only means the heat of the fire reaches our body is radiation.
But in the given situation the correct answer is convection.
Answer:
True

Many chickens lay eggs of that size and eggs from chickens are the most commonly used
Answer:
304.13 mph
Explanation:
Data provided in the question :
The Speed of the flying aircraft = 300 mph
Tailwind of the true airspeed = 50 mph
Now,
The ground speed will be calculated as:
ground speed =
or
The ground speed =
or
The ground speed = 304.13 mph
Hence, the ground speed is 304.13 mph
Answer:
current ia = 50 mA
Explanation:
given data
mesh-current analysis
current source in circuit = 50 mA
to find out
value of the current ( ia )
solution
we know here that in mesh-current analysis with independent or dependent current or contain only here one current source then
there value of the current will be
value of the current ( ia) = 50 mA
because value of current source is self indicated mesg current
so ia = 50 mA
