The Earth can be approximated as a sphere of uniform density, rotating on its axis once a day. The mass of the Earth is 5.97 x 10²⁴ kg , the radius of the Earth is 6.38 x 10⁶ m , and the period of rotation for the Earth is 24.0 hrs .
What is the rotational kinetic energy of the Earth?

What do you think car designers do if the damage caused by a crash test is too severe?

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.

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
