Answer:
7 miles northeast is the because it has both magnitude and direction .
Explanation:
Waste management (or waste disposal) includes the processes and actions required to manage waste from its inception to its final disposal.[1] This includes the collection, transport, treatment and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, economic mechanisms. Proper management of waste is important for building sustainable and liveable cities, but it remains a challenge for many developing countries and cities. A report found that effective waste management is relatively expensive, usually comprising 20%–50% of municipal budgets. Operating this essential municipal service requires integrated systems that are efficient, sustainable, and socially supported.[6] A large portion of waste management practices deal with municipal solid waste (MSW) which is the bulk of the waste that is created by household, industrial, and commercial activity.[7] Measures of waste management include measures for integrated techno-economic mechanisms[8] of a circular economy, effective disposal facilities, export and import control[9][10] and optimal sustainable design of products that are produced.
Answer:
166 kg *m/s
44 N upward
39 m/s east
Explanation:
The short answer: If it has direction, it's a vector.
The long answer:
Vectors, unlike scalars, have direction. The first one, 166 kg*m/s is momentum, since momentum is velocity*mass, and velocity is a vector, momentum must be a vector.
44 Newtons is a vector since it has direction, in this case, upward. Force is acceleration*mass, and since acceleration is a vector, force must be a vector.
39 m/s is velocity, velocity has a direction, therefore it's a vector.
13.7 grams is mass since mass doesn't change with direction, it's a scalar, the opposite of a vector.
86 miles per hour has speed, but speed has no direction, therefore it's a scalar.
12 meters is distance, distance has no direction, therefore it's a scalar.
Answer:
18s
Explanation:
Given parameters:
Work done by hamster = 180J
Power of hamster = 10W
Uknown:
Time taken for the hamster to generate the work = ?
Solution:
Power can be defined as the rate at which work is being done by a body. It is related to both work done and time by the expression below;
Power = 
Time taken = 
Time taken =
= 18s
