Answer:
a. 10 hours
b. Approximately 4.03 km/h to shore
Explanation:
The width of the English Channel at the narrowest point = 35 km
The speed of the current across the English Channel across the narrowest point = 2 km/h
a. The relative velocity of the swimmer north to south = 3 km/h
Therefore, the the time it would take the swimmer to swim north to south will be given as follows;
Time = Distance/Velocity = 35 km/(3.5 km/h) =10 hours
The time it would take = 10 hours
It would take 10 hours for her to cross the 35 km distance
b. Given that she has a relative velocity of 3 km/h north to south, we have;
The magnitude of her relative velocity to shore = √((Her relative velocity north to south)² + (The velocity of the English Channel east to west)²)
∴ The magnitude of her relative velocity to shore = √(3.5² + 2²) = (√65)/2 km/h
The magnitude of her relative velocity to shore ≈ 4.03 km/h
What is intensive physical property of matter?
PLEASE HELP
Answer:
Explanation:
An intensive property is a property of matter that does not change as the amount of matter changes. It is a bulk property, which means it is a physical property that is not dependent on the size or mass of a sample. In contrast, an extensive property is one that does depend on sample size.

Which of the following is NOT a major factor in understanding climate?
a water
b clouds
c mountains
d altitude
Answer:
The Answer is CExplanation:
Bc its not part of a Question and you can know now The mountains is not right and climesand this much be the answer i dont know tho so this got to be Its ok now b yc. mountains is not a major factor in understanding climate.
Water is a major factor which can affect the climatic condition the high water content in the atmosphere is responsible for rain where as low or less content in atmosphere makes the climate hot and dry. Clouds when are dense cause rain and when there are few clouds and less denser then it is indicative of a hot day. Places situated on high altitude have cool climate as compared to the places located on plains.Mountains do not affect the climatic condition of a region. Instead the altitude with which the mountain is associated will help in understanding the climatic condition.Hence, c. mountain is the correct option.

What is Otter's average velocity over his entire trip when it takes him 2 minutes to walk 100 meters north and another 1 minute to walk 70 meters south?Express your answer using the proper SI units. Round your answer to two decimal places, and include a direction if necessary.
Answer:
0.50m/s
Explanation:
Average velocity is the change in displacement of a body with respect to time.
Velocity = ∆S/∆t
∆S = 100m - 70m
∆S = 30m
∆t = 2min - 1 min
∆t = 1min = 60secs
Substitute the given parameters into the formula for velocity
Velocity = 30m/60s
Velocity = 1/2 m/s
Average Velocity = 0.5m/s
