Answer:
24300000K
Explanation:
Q=mc(change in temperature)
900X2.0=1800.0
1800.0X13500= 24300K
Total distance/total time is average speed. Total distance is 480miles. Total time is 5 hrs. 480/5=90mph
Answer: 8m/s^2
Explanation:
By Newton's second law we have that.
F = m*a
Where F is force, m is mass and a is acceleration.
We know that m = 50kg and F = 400N
400N = 50kg*a
a = (400/50) m/s^2 = 8m/s^2
The reason a car traveling in the opposite direction of the way you're traveling is simple. if you are going one way, and cars are passing you on the other, it appears that they are going much faster than they are. the combination of your relative speeds means that those cars might appear to be doing 60mph, rather than 30mph.
