Answer:
B) 40 km West
Explanation:
Let position of B is origin so with respect of City B the position of A is given as
south of city B
now Bus starts from City A and travels a distance of 50 km at 37 degree North of East to reach city C
so it is
now the position of C is given with respect to A
in order to find the position of C with respect to B we can say
so in order to reach at city B from city C bus has to travel 40 km towards West
Answer:
42.99°
Explanation:
= Kinetic friction force
= Pulling force at angle
= Weight of the box = 150 N
Kinetic friction force
Pulling force at angle
N = Pulling force
According to question
Applying Newton's second law in the vertical direction we get
The angle is 42.99°
freezing
During freezing, the temperature of a substance remains constant while the particles in the liquid form a crystalline solid. Because particles in a liquid have more energy than particles in a solid, energy is released during freezing. This energy is released into the surroundings.
