Low boiling point is covalent.
Answer:
Explanation:
Remark
The only thing that might trip you up is what to do with the angle. The vertical component of the 15 degrees does no work against anything. So the 15 degrees limits the horizontal force.
The formula is
Work = F * d * cos(15)
The givens are
F = 2000 N
d = 30 m
Cos(15) = 0.9659
Solution
Work = 2000 * 30 * cos(15)
Work = 57,955
Rounded to two places would be 5.8 * 10^4
C
Answer:
4.75 m/s^2
Explanation:
The rate of change of velocity is called acceleration.
initial velocity, u = 15 m/s along east
Final velocity, v = 40 m /s along north
time, t = 9 s
Change in velocity,
Acceleration,
Magnitude of acceleration
= 4.75 m/s^2
