Answer:
0.65812
Explanation:
m = Mass of suitcase = 16 kg
= Incline angle = 40°
g = Acceleration due to gravity = 9.81 m/s²
a = Acceleration of the block = 1.36 m/s²
f = Frictional force
The normal force is given by

In x direction

Frictional force is given by

The coefficient of kinetic friction between the suitcase and the ramp is 0.65812
Answer:
The density of balsa wood is about 170 kg/m^3.

Both
in the domestic and international guidelines tell that when two power-driven
vessels are crossing so as to contain risk of collision, the vessel which has
the other on her starboard side (the give-way vessel) must keep out of the way.
If
you are the give-way vessel, it is your responsibility to avoid a collision. Normally,
this means you must change speed or direction to cross behind the other vessel
which is the stand-on vessel.
At
evening, when you perceive a red light crossing right-to-left in front of you,
you need to change your course. But if you perceive a green light crossing from
left-to-right, you are the stand-on vessel, and should maintain course and
speed.
The leading situations of collision risk are meeting head-on, overtaking, and crossing. When one of two vessels is to keep out of the way (give-way vessel), the other, the stand-on vessel, must uphold course and speed.
Answer:
False
Explanation:
A compass can be used to determine relative direction but not absolute direction.
By knowing the solar. And the sun disk.
