Answer:
Explanation:
KE = ½mv² = ½(6.8)8² = 217.6 J
round as appropriate because that result is way too much precision for the inputs provided. Arguably should be 200 J based on the single significant digit of the velocity.

Answer: The field lines bend away from the second positive charge
Explanation: opposite attracts, same repulse
Answer:
Its internal energy decreases by 40 J.
Explanation:
The energy supplied to the metal block causes the temperature of the block to rise. Therefore,

Now, we will use this value of mC to find out the energy change of block:

It shows that when the temperature of the metal block falls by 10°C,
<u>Its internal energy decreases by 40 J.</u>
Answer:
7: C 8:All of These
Explanation:
Im almost 100% sure on both of these. Feedback is like critism and you'll get nowhere focusing on all good and no bad. You can't go to the doctor on your own if you're a child for technically it's both yours and your parents.
