Answer:
Explanation:
Below is an attachment containing the solution to the question.
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.
Answer: 
Explanation:
In the image attached with this answer are shown the given options from which only one is correct.
The correct expression is:
Because, if we derive velocity 
with respect to time 
we will have acceleration 
, hence:
Where 
is the mass with units of kilograms (
) and with units of meter per square seconds 
, having as a result 
The other expressions are incorrect, let’s prove it:
This result has units of 
This result has units of
This result has units of 
and 
is a constant
This result has units of
This result has units of
This result has units of 
and is a constant
This result has units of 
and is a constant
because 
is a constant in this derivation respect to
This result has units of 
and is a constant
Answer: The correct answer is Image B.
Explanation: For an object to accelerate, there should be unbalanced forces present. An object will move in the direction of net force.
Balanced forces are defined as the forces acting on the same object which are equal in magnitude but act in opposite direction. The net forces are 0.
Unbalanced forces are defined as the forces acting on the same object which are unequal in magnitude. The net force is non-zero.
For the given images:
Image A: This box will accelerate easily because the net force is non-zero and is moving in right direction.
Image B: This box will not accelerate because the net force is zero as all the forces are balancing one another. Hence, the object will stay at rest.
Image C: This box will accelerate easily because the net force is non-zero and is acting in between the normal and applied force.
Image D: This box will accelerate easily because the net force is non-zero and is moving in right direction.
Hence, the correct option is Image B.
