It’s the gravity pull of the sun that makes them spin around 360 degrees
It’s all so why they say In a billion years the sun will smash into the sun
-facts :)
The correct answer is
<span> 4. protons are positively charged.
In fact, the direction of the electric field of a charged particle depends on the sign of the charge of the particle. While a negatively charged particle (such as the electron) produces an electric field that points toward the charge, a positively charged particle (like a proton) produces an electric field that points away from the charge. This can be proofed by using a positive test charge: if we put a positive test charge near a proton, this test charge will move away from the proton (because it is repelled from it, since they have same charge), and the direction of its motion gives the direction of the electric field generated by the proton, so away from it.</span>
Answer:
Explanation:
Given:
- mass of aluminium,
- initial temperature of the aluminium cylinder,
- mass of coffee,
- initial temperature of coffee,
- specific heat of coffee (assuming water),
- specific heat of aluminium,
When the coffee and the aluminium cylinder come in contact then heat released by the coffee is equal to the heat gained by the aluminium.
<u>Mathematically:</u>
is the final temperature of agreement.
Answer:
the answer is b
Explanation:
gravity pulls you down so on a scale you will weigh more. less gravity you will weigh less.
