Answer:
the answer will be C. 4 degrees C
Explanation:
you subtract base meters from peak meters to get 4 meters; then Multiply 6.5 by 4.
Then subtract that total from 30 degrees C
***as altitude increases, temperature decreases***
Answer:
Exposure to the Atmosphere
Composition of Rock
Surface area of the rock
Climate
Time
Explanation:
Exposure to the Atmosphere - how much of the rock mass is exposed to the environment affects how quickly the rock will be weathered by that very environment
Composition of Rock - what kind of minerals the rock is made of, how easy it is for those minerals to disintegrate and how quickly the react with water and air.
Surface area of the rock - a rick that has a wider surface or smaller pieces is more exposed than one that is a lump. A larger surface area increases the rate of weathering
Climate - if a rock is an area where there are high temperatures or very low temperatures, the rate of weathering is likely to increase. A similar point can be made about a region that experiences a lot of rain.
Time - the longer the rock is exposed to harsh conditions, the more it will experience weathering
Answer:
3.36 Joules
Explanation:
Work done= Force × distance
F=4.2 N
distance= 0.8 m
work done= 4.2 × 0.8
work done= 3.36 Joules
Answer:
-2.79 m/s²
Explanation:
Given:
v₀ = 20 m/s
v = 11 m/s
Δx = 50 m
Find: a
v² = v₀² + 2aΔx
(11 m/s)² = (20 m/s)² + 2a (50 m)
a = -2.79 m/s²
Round as needed.
Answer: counterclockwise
Explanation:
As the area of the loop decreases steadily, the flux through the loop also decreases. By Lenz’s law, any induced current will tend to oppose the decrease. Using Flemming right hand rule (Fleming's right-hand rule which shows the direction of induced current) we know that magnetic field inside the loop due to a counterclockwise current comes out of the plane. Therefore a counterclockwise current will create a stronger magnetic field inside
the loop, tending to increase the flux.
When a wire loop is moved in the direction of the current or a wire loop is being pulled through a uniform magnetic field there would be no induced current ( current loop is said to be zero)
