A chemical property of gasoline is that it will burn in air. Gasoline is a substance that is used to power automobiles. Gasoline will oxidize
in air which means that it reacts with oxygen in air. Hope this answers the question. Have a nice day.
The combination of decay processes that would convert U-239 into PU- 239 is beta decay followed by another beta decay. There are two different types of beta decay (positive and negative beta decays) they both occur simultaneously in order to move the atoms towards stability.
Explanation:
Heat flow = conductivity × area × change in temperature / thickness
q' = kAΔT/t
13.3 W = k (1.56 m²) (7.8°C) / (0.0234 m)
k = 0.0256 W/m/°C
Heat lost by water = heat gained by ice
-mCΔT = mL + mCΔT
-(1000 g) (1 cal/g/°C) (12°C − 37°C) = m (79.7 cal/g) + m (1 cal/g/°C) (12°C − 0°C)
25,000 cal = (91.7 cal/g) m
m = 272.6 g
Answer:
Explanation:
Given that,
The blade of a windshield wiper moves through an angle of 90.0° in 0.397 s
The radius of the circlular path is 0.376 m
We need to find the magnitude of the centripetal acceleration of the tip of the blade. Let it is a. The formula of the centripetal acceleration is given by :
v is velocity, 
It moves through an angle of 90 degrees, it means 
So,
So, the magnitude of the centripetal acceleration of the tip of the blade is 
.
Answer:
Object in motion: By the Newton's first law about inertia, an object in motion tends to keep in motion, unless an external force act on it.
Object at rest: By the Newton's first law about inertia, an object at rest tends to keep at rest, unless an external force act on it.
