Answer:
Only there will be a change in density of sun.
Explanation:
As your question says only the radius of sun is decreased and there is no change in the mass. So it means that the center of gravity will be the same and as a result the gravitational force remains the same. Only the density of sun changes as it shrinks.
Responder:
18.75 atmósferas
Explicación:
Paso uno:
datos dados
volumen inicial V1 = 25L
Presión inicial P1 = 7.5 atm
volumen final V2 = 10L
presión final P2 = ??
Segundo paso:
Aplicando la expresión de gas que relaciona el volumen y la presión, es decir
P1V1 = P2V2
sustituyendo nuestros datos tenemos
7.5 * 25 = P2 * 10
187.5 = P2 * 10
divide ambos lados por 10
P2 = 187.5 / 10
P2 = 18.75 atmósferas
<em><u>La presión final es de 18.75 atm.</u></em>
Answer:
Sorry this isn’t going to be any help. You don’t have any statement that I’m able to see.
Explanation:
A concave mirror is a curved mirror that bulges inward. Objects reflected in concave mirrors often appear bigger than they really are, although the specifics of how the image appears depends upon the object's distance from the mirror. Concave mirrors are used in car headlights, in dentist's offices and in makeup mirrors.
Explanation:
The force on the passenger will be F = ma
Here, m does not change, but a is the variable.
If the cars slows down very fast, the acceleration will be higher, and thus the force will be higher.
If the acceleration is lower, the force will be lower as well, which would be the most desirable scenario for the passenger.
