Mass is the amount of matter present in an object, it also determines the strength of the mutual gravitational force of an object to another object. Volume is the amount of space that the object occupies. Meanwhile, density is the amount of mass per volume of an object, with that formula, we can say that density is directly proportional to the mass but indirectly proportional to the volume.
Answer:
Answer:
15.67 seconds
Explanation:
Using first equation of Motion
Final Velocity= Initial Velocity + (Acceleration * Time)
v= u + at
v=3
u=50
a= - 4 (negative acceleration or deceleration)
3= 50 +( -4 * t)
-47/-4 = t
Time = 15.67 seconds
Answer:
La velocidad angular del niño y del carrusel cuando se mueven juntos es 0.208 radianes por segundo.
Explanation:
Asumamos que tanto el niño como el carrusel no tienen carga externa aplicada sobre aquellos, de modo que se puede aplicar el Principio de Conservación de la Cantidad de Movimiento Angular:
(1)
Donde:
- Masa del niño, medida en kilogramos.
- Velocidad lineal inicial del niño, medida en metros por segundo.
- Radio máximo del carrusel, medida en metros.
- Momento de inercia del carrusel, medida en kilogramo-metros cuadrados.
- Velocidad angular final del sistema niño-carrusel, medida en radianes por segundo.
Si sabemos que 
, 
, 
y 
, tenemos que la velocidad angular final es:
La velocidad angular del niño y del carrusel cuando se mueven juntos es 0.208 radianes por segundo.
Answer:
<h2>
The potential difference increases </h2>
Explanation:
from the relation 
where E= electric field (force per coulomb)
V= voltage
d= distance
Hence the voltage is going to be V= E×d.
Therefore this means that increasing the distance increases the voltage.
Answer: 49.92 m
Explanation:
In this situation the following equation will be useful:
Where:
is the final velocity of the car, when it finally stops
is the initial velocity of the car
is the constant acceleration of the car after the driver slams on the brakes
is the stopping distance
