Answer:
D
The answer cannot be found until it is known whether q is greater than, less than, or equal to 45°.
Explanation:
Since block moves with constant speed
So, frictional force
f = FCosq
Work done by friction
W = - fd
W = - fd Cos q
The answer may be greater or less than - fdSinq. It depends on the value of q which is less than, or equal to 45°.
Winter and Summer happen every year, pretty much on schedule.
When they happen, the 'weather' changes, but the 'climate' doesn't.
If you live in the right place, then you might get several blizzards every
Winter. They're changes in the 'weather' but not in the 'climate'.
If the temperature where you live stays well below zero for a hundred
years, then you might be entering an ice age.
Or let's say your town has had blizzards every Winter for the past 20 years
but it never had one for 100 years before that.
Either of these would be a climatic change.
