Ben is exercising his pony on a large, oval track. The pony is trotting at a constant speed of 10 m/s around the track. Which statement can be made about the pony's acceleration? A) The pony is decelerating. B) The rate of acceleration varies. C) The pony is accelerating around the track. D) The pony is not accelerating around the track.

Answers

Answer 1
Answer:

Answer: Hello mate!

The velocity of the pony is constant in magnitude, so you may think that the pony is not acelerating, but you need to notice that the track has an ocal shape.

This means that the direction of the velocity is changing all the times, this mean that there is an "acceleration" changing the direction of the velocity, this is called centripetal acceleration, then the pony is accelerating around the track.

The right answer is C.

To increase the amount of electricity produced in the U.S., we could place what on top of all Wal-Mart stores?Turbines

Biomass incinerators

Wind farms

Solar panels

Answers


That's a great idea !  A wind turbine (windmill) or solar panels
on the roof of every WalMart, but don't stop there.  Let K-Mart,
Target, Sears, Macy's, 7-11, McDonald's, and Subway in on it too. 

In fact, why not place them on the roof of every house and
apartment building too ?

Just one question:  Who's going to pay for them ?
_________________________________________________

The biggest single year-round residential use of energy in the
USA is to heat up and keep a ready supply of hot water.  So the
single biggest residential use of energy could be eliminated with
a simple solar water heater on the roof of every house.  From my
own personal observation, I know that Israel is there now, but here
in the USA, it's apparently not worth the time, effort, or expense ! ? !

The question will be looking for Solar Panels, as they are flat, non-intrusive, and reasonably low maintenance ie the most sensible choice.

However I mean in theory you could stick windmills on top of big Wal-Mart stores as wind turbines are placed on roofs regularly, so you can tell whoever set you that question that it is vague ;)

Magnesium is a metal that is commonly used in products that needed to be light weight. Suppose a 2.00kg piece of magnesium has 8160 j of entertainment added to it it's temperature increases 4K what is the specific heat of magnesium

Answers

Given that,

Mass of magnesium, m = 2 kg

Heat added to it, Q = 8160 J

Increase in temperature, \Delta T=4\ K

To find,

The specific heat of magnesium.

Solution,

Th formula that is used to find the heat required to raise the temperature in terms of specific heat is given by :

Q=mc\Delta T\n\nc=(Q)/(m\Delta T)\n\nc=(8160\ J)/(2\ kg* 2\ K)\n\nc=2040\ J/kg-K

So, the specific heat of magnesium is 2040\ J/kg-K.
