Answer:
living in rural areas or places most affected by climate change (like communities along the coast) relying on surrounding environment and natural resources for food, cultural practices, and income. coping with higher levels of existing health risks when compared to other groups.
Explanation:
Answer: He must drive at 58.8mi/hr
{3 significant figure}
Explanation: The original speed of the car to complete the journey normally is = 550mile/10hr
= 55mi/hr
The normal time to cover 120 mile with that speed is
t = distance/speed
= 120/55
=2hr, 0.18*60=11mins
= 2hr11mins.
But the driver found out he was 30mins behind at this distance, so he spent
2hr 11min +30min= 2hr41mins
For him to meet up the original schedule time 10hrs, he has
(10-2.41)hrs = 7hr19mins to cover the remaining distance of
{550-120}=430mile.
First, 7hr19mins= {7*(19/60)}hr
= {439/60}hr
Now let's find the speed at which the driver must move for him to cover for his initial delay
Speed= distance/time
= 430/{439/60}
This is same as writing
Speed = 430/439/60
Using the law of reciprocal,
Speed = (430*60)/439
= 25800/439
= 58.7699mi/hr
But we were asked to leave our answer in 3 significant figure. Therefore,
Speed = 58.8mi/hr
Answer: The velocity magnitude or the velocity direction chages.
Explanation:
According to Newton's second law of motion, the acceleration of a system moved in same direction and is also directly proportional to the external force which acts on it while inversely proportional to the mass. The formula is: a = F/m
Based on the question, since the object obtains acceleration, then it can be infered that there will be changes in the velocity magnitude or the direction as a result of the motion.
Answer:
Control Variable
Explanation:
This is because time has to be the same for both materials throughout the experiment (an hour in this case).
