gold is the piece of metal which have larger mass.
Explanation:
because it is reactive in nature than copper
Because gold has a greater density than copper therefore 1 cm3 of gold is equal to a mass of 19.3 g while 1 cm3 of copper is 8.9 g

How much energy is required to completely melt a 250 gram ice cube that is already at 0 degrees Celsius? Show your work & units. Expected Answer = 83,500 J
Answers
Answer:
Q = 83500J
Explanation:
[tex]Q = L_{ice} *m[/tex]
[tex]L_{ice} = 3.34*10^{5} \frac{J}{kg}[/tex]
[tex]m = 250g = 0.25kg[/tex]
[tex]Q = (3.34*10^{5} \frac{J}{kg})*(0.25kg)[/tex]
[tex]Q = 83500J[/tex]

A pitcher throws a softball toward home plate. When the ball hits the catcher’s mitt, its horizontal velocity is 32 meters/second. The softball’s velocity goes to 0 meters/second in 0.8 seconds when caught. If the softball has a mass of 0.2 kilograms, what’s the force of the impact? Use F = ma, where .
Answers
Answer:
To calculate the force of impact F, first lets calculate the acceleration a of the ball:
a=v/t where v is the velocity of the ball and t is time
a=32/0.8=40 m/s²
To get the force F we need the Newtons second law:
F=m*a where m is the mass of the ball and a is the acceleration.
F=m*a= 0.2*40 = 8 N
So the impact force is F= 8 N.

How do water, wind, and thermal energy from the sun move about the earth's surface?
Answers
Molecules move more quickly because the sun's light energy transforms into heat energy on the planet. While cooler polar air and water travel away from the poles and towards the equator, warm air and water molecules rise and move in the opposite direction.
What is light energy ?The capacity to make different forms of light visible to human sight makes light energy a sort of kinetic energy. Light is referred to as an electromagnetic radiation that is produced by hot things like the sun, lasers, and lightbulbs. Photons, which are tiny energy packets, are present in light.
Water temperature, biological activities and plant photosynthesis and development are all impacted by light energy.
The air is heated by the sun, and warm air rises. The colder air from the surroundings is forced to enter to replace the rising heated air. The result of this is the wind. Ocean currents function similarly.
Thus, Molecules move more quickly because the sun's light energy transforms into heat energy on the planet.
