Looters break a statue into pieces. how do you expect the weathering of pieces of rock to change

This definitely has to do with erosion. We can expect that the statue will weather faster because of more surface area.I hope this is what you were looking for

A hailstone traveling with a velocity of 43 meters/second comes to a virtual stop 0.28 seconds after hitting water. What is the

lisabon 2012 [21]

Magnitude of acceleration = (change in speed) / (time for the change) .

Change in speed = (ending speed) - (starting speed)

= zero    - (43 m/s)

=    -43 m/s .

Magnitude of acceleration = (-43 m/sec) / (0.28 sec)

      = (-43 / 0.28) (m/sec) / sec

      =    153.57... m/s²

      = 1.5... x 10² m/s² .

(1) Electric current is defined as the rate of charge flow past a given point in an electric circuit. It is measured in Coulombs/second, also called Amperes. In DC electric circuits, it can be assumed that the resistance to current flow is a constant so that the current in the circuit is related to voltage and resistance by Ohm's law, which is:

V = I*R
Where V = Voltage
I = Current
R = Resistance

(4) Renewable energy is the energy which is generated from the natural sources i.e. sun, tides, wind etc. Examples are: Solar Energy, Wind energy( windmill) etc. for electricity generation.
Advantages of Renewable Energy:
1) It is available in abundant quantity.
2) It is free to use.
3) It has low carbon emissions, therefore it is considered as green and environment friendly.
Disadvantages of Renewable Energy:
1) It is not easy to setup plants and machinery for renewable energy.
2) Initial costs for setting up those plants and machinery is quite high.
3) The energy from the natural sources is not available 24/7. In Solar energy case, energy can be used during the day time and not during night or rainy season etc.

Non-Renewable energy is energy which is taken from the sources that are available on the earth in limited quantity. Sources may be fossil fuels, natural gas, oil and coal etc.
Advantages of Non-Renewable Energy Sources:
1) They are easy to use.
2) They are cheap.

Disadvantages:
1) They will expire some day (as they are limited).
2) The speed at which such resources are being used can have serious environmental changes.
3) They release toxic gases in the air when burnt which are the major cause for global warming.
4) Since these sources are going to expire soon, prices of these sources are proliferating day by day.

Now you should judge all by yourself which is the better energy source.
