The height of the tower and the distance from its base form a right angle triangle. Thus,
tan(∅) = height / base
tan(28.81) = height / 1,000 m
height = 549.98 meters
Some one already asked this question and you can copy paste and google it but I believe it is c you may want to double check
Answer:
Explanation:
According to Charles Law
=> 
Where 
= 0.0279 m³, 
= 280 K and 
= 320 K
=> 
=> 
= 0.03189 m³
Answer:
0.41
Explanation:
A 49 N block has a mass of 5 kg:
49/9.8
A horizontal force of 50 N giving it an acceleration of 6 m/s^2 means that 30 N is taken up by the acceleration
This leaves 20 N to take care for friction. so the coefficient of friction is:
20/49 = 0.41.
