Answer:
The coastal regions are affected by abrasion due to large volumes of water and increased winds. This can become more severe especially with storms that hit coastal regions.
Explanation:
Abrasion is physical weathering caused by water, wind and gravity. Hope it worked, I love geography! Can you mark mine as the brainliest please! Also can you give me a thanks and a 5 star vote!
d.) a and b only
This is because sound needs a medium to travel. It can travel in a solid (the fastest) and air for example. Sound waves cannot propagate through a vacuum and since space is a vacuum the answer is a and b only.
Answer:
Explanation:
Given that
F=ax^3/2. a is a constant
The force does a work of
W=2.01KJ from x=0 to x=15.2m
We need to find a
Work is give as,
W=∫F.ds
But this is in x direction only then,
W=∫Fdx. from x=0 to x=15.2m
W=∫ax^3/2dx from x=0 to x=15.2m
W=ax^(3/2+1)/(3/2+1).
W=ax^(5/2)/5/2
W=ax^(2/5)/2.5 from x=0 to x=15.2m
Cross multiply
2.5W=ax^2.5. from x=0 to x=15.2m
2.5W= a (15.2^2.5-0)
W=2.01KJ=2010J
2.5×2010=a×900.76
Therefore,
a=5.56
Answer:
31.96362 °C
Explanation:
= Mass of air in the room = 947 kg
= Mass of air entering the room = 62.4 kg
= Temperature in the room = 33.2°C
= Temperature air entering the room = 13.2°C
T = Equilibrium temperature
c = Specific heat of air = 1006 J/kg °C
In the case of thermal equilibrium we have the relation
The temperature of thermal equilibrium is 31.96362 °C
