Hello!
The potential energy of a 25 kg bicycle resting at the top of a 3 m high hill is _______ J
If: 1 Joule = 1 kg.m²/s²
We have the following data:
GPE (Gravitational Potential Energy) = ? (in J)
m (mass) = 25 kg
g (gravity) ≈ 9.81 m/s²
h (height) = 3 m
We apply the data to the formula of the gravitational potential energy, we have:
Answer:
735.75 J

Elements of weather
Explanation:
Weather can be defined as the atmospheric conditions of a particular area over a short period of time.
Air pressure, humidity, clouds and temperature are all called elements of weather. The other elements of weather are;
- Wind
- Precipitation.
Air pressure, humidity, clouds, and temperature are all part of weather and climate studies. They represent the weight of air above a point on the earth's surface, the amount of water vapor in the atmosphere, collections of airborne water droplets or ice crystals, and the heat energy in the atmosphere, respectively.
Air pressure, humidity, clouds, and temperature are all components of weather and climate studies, key elements of geography and meteorology. Air pressure is the force exerted by the weight of air above any given point on Earth's surface. Humidity refers to the amount of water vapor in the atmosphere. Clouds are collections of water droplets or ice crystals that form in the Earth's atmosphere when water vapor condenses. Temperature is a measure of the amount of heat energy in the atmosphere, usually expressed in degrees Celsius or Fahrenheit. The combination of all these factors form different weather patterns and influence the Earth's overall climate.

Answer:
DE HECHO EL SONIDO DÍ PUEDE ATRAVESAR LAS PAREDES, PERO
CUANDO ENTRA EN LA PARED, EL SONIDO VIAJA MÁS RÁPIDO QUE EN EL
AIRE Y CUANDO SALE DEL OTRO LADO, EL SONIDO VA A UNA
VELOCIDAD ALTA, POR ESTO LSA VOCES SE ESCUCHAN AUNQUE NO
MUY CLARAS.
Explanation:
Sonny's average speed in the race
Speed = Distance/Time
=> Speed = 100m/16s
=> Speed = 6.25m/s
=> Speed = 6.25 ms^-1
