An article in a magazine denies that Earth is warming and climate change is occurring. The writer reports that this season was the snowiest winter on record for the Northeast, with lower than average temperatures for the region. Because of the low temperatures, the writer concludes that climate change cannot possibly be occurring. What question should you ask the writer to clarify whether his stance on climate change is scientifically sound?(A) Did the snowstorms cause extensive damage?(B) Was this the coldest month on record for this region?(C) Were the snowfall totals of each storm larger or smaller than last year?(D) Were long-term temperature changes investigated in addition to short-term change?

The gravitational force of two objects, by definition, is given by:
Where,
G: gravitational constant
m1: mass of object number 1.
m2: mass of object number 2.
d: distance between both objects.
Therefore, according to the given equation, a change that always results in an increase in gravitational force is:
Increase in the mass of the objects and decrease in the distance between them.
Answer:
A change that will always result in an increase in the gravitational force between two objects is:
Increase in the mass of the objects and decrease in the distance between them.

"When The motional emf generated between the ends of the wire is e = 17745.1 V".
What is Motional emf generated?
When Motional EMFs in the Earth’s weak magnetic occupation are not ordinarily very large, we would notice voltage along metal rods, Than such as a screwdriver, during ordinary motions. For illustration, a simple computation of the motional emf of a 1 m rod moving at 3. 0 m/s perpendiculars to the Earth’s field gives emf is = Bℓv
Then Length, l is = 4.32 x 10^4 m
Then speed, v is = 7.07 x 10^3 m/s
Now the magnetic field, B is = 5.81 x 10^-5 T
Now, The formula for the motion emf is given by
e is = B x v x l
e is = 5.81 x 10^-5 x 7.07 x 10^3 x 4.32 x 10^4
Therefore, e = 17745.1 V
Find more information about Motional emf generated here:
Answer:
Explanation:
Length, l = 4.32 x 10^4 m
speed, v = 7.07 x 10^3 m/s
magnetic field, B = 5.81 x 10^-5 T
The formula for the motion emf is given by
e = B x v x l
e = 5.81 x 10^-5 x 7.07 x 10^3 x 4.32 x 10^4
e = 17745.1 V

Humans impact the environment, which can, in turn, have an effect on human health. Pollution is caused by human activity, and it also affects human health. Air pollution can cause respiratory problems and water pollution can lead to digestive problems. As human health is affected by these issues, concern increases and policies are enacted that address the causes of the issues. These policies do benefit the environment, but are, in part, brought about by concerns over human health.

Explanation:
When a magnet is placed at the centre of the paper, and the nails are sprinkled on the paper, what will happen to the nails is that, the nails will form a pattern on the paper according to the magnetic field of the bar magnetic pole.
Other phenomena you can observe are:
1.) The nails will align themselves and show some lines of forces which is equivalent to the magnetic field lines
2.) The direction of the line of forces
3.) The strength of the magnetic field pole.
