Answer:
The normal force will be lower than the gravitational force acting on the car. Therefore the answer is N < mg, which is <em>option B</em>.
Explanation:
Over a round hill, the centripetal force acting toward the the radius of the hill supports the gravitational force (mg) of the car. This notion can be expressed mathematically as follows:
At the top of a round hill
At the foot of a round hill
Answer:
1. C: 31/14 Si becomes 31/15 because a nuetron
2. A: 238 92U because the very long half-life means a very small rate of decay
3. D: Charge conservation is not satisfied
4. B: of the four nuclear decay processes only the α-decay changes the baryon number and does so in increments of four

I just took the quick check. Enjoy the answers I did not get to have
When Debbie pushes the first cart she is using an applied force. An applied force is created when someone or something pushes another thing using, of course, an applied force. Now, when the second cart is being pushed by the first cart, this is also an applied force. You can tell because the first cart is being pushed using forced and this causes the second cart to be pushed using some of the force that is being transmitted to the first cart.
Debbie exerts applied force on the first cart. The first cart exert applied force on the second cart.

Sodium and potassium are positively charged ions called cations, and chloride and phosphate form negatively charged ions called anions. is true!
Answer:
Earth pulls the sun towards itself with a force equal to the ratio of the mass of the sun to the mass of Earth
