Answer:
speed in km/min:
0.3km/min
speed in km/h:
18km/h
speed in m/s:
5m/s
Explanation:
the average speed is defined as:
where 
is the speed, 
is the distance traveled, and 
is the time
according to the statement:
and
(10 minutes are equal to a sixth of an hour which is 600 seconds)
Because the units in which the speed is required are not indicated, here are some options for the answer:
Depending on the units in which you need the speed, are the quantities you should use.
Speed in km / h (kilometers per hour):
speed in m / s (meters per second):
or the speed in km/min (kilometers per minute)
Answer:
option C
multiplication factor n = 1 when volume change to half and pressure become double
Explanation:
we know by Ideal Gas law:
P1V1 = nRT1
P2V2 = nRT2
according to the question
pressure is doubled and volume is reduced to half
so we have
new pressure = 2*P1
new volume = V1/2
hence,
(2P1) * (V1/2) = nRT2
P1V1 = nRT2
we have now
nRT1 = nRT2
we get
T1 = T2
thus no change in temperature
we know that internal energy is given as
internal energy = nCvT,
since temperature is directly proportional to internal energy and since temperature remains constant therefore internal energy remains constant
So there is no change in internal energy
thus, multiplication factor n = 1 when volume change to half and pressure change to double
During both the Vernal Equinox and Autumnal equinox, there is an equal amount of night and day
Vernal Equinox marks the beginning of Spring and Autumnal Equinox marks the beginning of Fall
hope this helps
Explanation:
observation is something what you could observe from your organs like eyes ears etc and also it is what you observed during an event for an experiment but inference is what you decide to do after observation or an event.
the act of inferring (to derive by reasoning). Observation = an act or instance of noticing or perceiving.

Answer:
C. Up, equal to the can's weight
Explanation:
You are camping in the breathtaking mountains if Colorado. You spy an unopened diet soda can floating motionless below the surface of a lake. What is the direction and amount of force the water exerts on it?
A. Zero
B. Down, equal to the can's weight
C. Up, equal to the can's weight
D. Not enough information is given
from the principle of flotation which states that a
When a body displaces a weight of water equal to its own weight, it floats. : A floating object displaces a weight of fluid equal to its own weight. ... Archimedes' principle equates the buoyant force to the weight of the fluid displaced.
the upthrust (this is the upward vertical force exerted on an object in fluid)in the water equals the weight of the body in water it floats.
