Answer:
Food accounts for 10-30% of a household's carbon footprint, typically a higher portion in lower-income households. Production accounts for 68% of food emissions, while transportation accounts for 5%.
Explanation:
Answer:
7 mm per year
Explanation:
It is given that :
The Pacific plate is moving towards north at = 29 mm per year
The Pacific plate is moving towards west at = 20 mm per year
We have to calculate the total relative motion towards the northwest.
So we have to find the resultant of the two motions.
Since the two movements are perpendicular, therefore the angle between the two motions is 90 degree.
Therefore, finding their resultant,


R = 7
Therefore, total relative motion towards the northwest is 7 mm per year.
Answer:
See the answers below
Explanation:
In this problem, we must be clear about the concept of weight. Weight is defined as the product of mass by gravitational acceleration.
We must be clear that the mass is always preserved, that is, the mass of 15 [kg] will always be the same regardless of the planet where they are.

where:
W = weight [N] (units of Newtons)
m = mass = 15 [kg]
g = gravity acceleration [m/s²]
Since we have 9 places with different gravitational acceleration, then we calculate the weight in each of these nine places.
