Answer:
El peso es de 882 newton.
Explicación:
El helicóptero se detiene a la altura en la que volaba para dejar caer una caja de 90 kg al suelo, el peso de la caja llega hasta los 882 Newton porque el peso es una fuerza dirigida hacia el centro de la tierra y depende de la gravedad. La fórmula del peso es multiplicar la masa por la gravedad, de modo que cuando se multiplican 90 kg de masa por 9,8 metros / seg2, obtenemos el peso del objeto que es 882 newton.
Answer:
A circuit which has a battery in it will not allow electricity to flow through it. A device called a switch can be used to complete a circuit so that other devices can be switched on or off.

Answer:
Explanation:
It is given that,
Area of cross section of the pipe, 
Area of cross section of the another pipe, 
Speed of water in first pipe, 
To find,
Speed of the water flowing in the second pipe.
Solve,
Let 
is the speed of water flowing in the second pipe. The relation between the area of cross section and the velocity is given by the continuity equation. It is given by :
Therefore, the water is flowing in the second pipe at the rate of 8 m/s.
The cell division occurs during the mitotic phase.
When a gas is compressed rapidly, temperature increases because temperature and volume of gas are inversely proportional to each other according to gas laws. When a gas is compressed rapidly, its volume decreases leading to increase in temperature.
Also the pressure increase which also increases the randomness of the gas molecules which start to collide more frequently and thus the temperature rises .
just to make you understand what randomness affects - you would have noticed that you often sweat in a small room filled with people but it’s cooler if the same number of people are there in a bigger room.
hope it helps you
