Acopper sphere was moving at 40 m/s when it hit another object. this caused all of the ke to be converted into thermal energy for the copper sphere. if the specific heat capacity of copper is 387 j/(kg ⋅ c°), what was the increase in temperature?

0.23 c°
0.81 c°
1.3 c°
2.1 c°

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
