Responder:
39200 J
Explicación:
Dado:
Masa de Tamara (m) = 50 kg
Altura a la que se encuentra Tamara (h) = 80 m
Aceleración debido a la gravedad (g) = 9.8 m / s²
La energía potencial de un objeto de masa 'm' ubicada a una altura 'h' sobre el suelo se da como:
![U=mgh](https://tex.z-dn.net/?f=U%3Dmgh)
Ahora, conecte los valores dados y resuelva la energía potencial. Esto da,
![U=50\times 9.8\times 80\\\\U=39200\ J](https://tex.z-dn.net/?f=U%3D50%5Ctimes%209.8%5Ctimes%2080%5C%5C%5C%5CU%3D39200%5C%20J)
Por lo tanto, la energía potencial de Tamara ubicada a una altura de 80 m es 39200 J.
The three units used to express pressure are pascal (Pa), atmosphere (atm), and Hg (torr).
The electrical forces pulls nucleus apart
Answer:
Mass on the moon: 5 Kg
Explanation:
Mass will stay the same. Mass of an object does not depend on gravitational force as it is the quantity on matter possessed by a body.
Answer:
D. Meters/Seconds
Explanation:
The time period of a wave is measured in seconds.
A typical wave involves both time and distance. Consider a sound wave, which is basically a periodic modulation of the local air pressure. We "hear" the sound because our ears respond to the variations of pressure.
The most common metric of a sound wave is frequency. This is the rate at which the change in pressure occurs, and is measured in cycles per second, formally known as "hertz". The period is the inverse of frequency andl has the units of seconds per cycle, commonly stated simply as seconds.
