Opening the valve allows more of the pressurized material out. If the area is decreased, less of the pressurized material is released, and its force ends up more spread out, reducing the pressure. Opening the valve will increase volume of transfer of your liquid.
Answer:
El observador verá correr al perro sobre la cubierta del barco a una velocidad de 40 kilómetros por hora.
Explanation:
Para determinar la velocidad del perro con respecto al observador sentado desde la playa a través del concepto de velocidad relativa, descrito en la siguiente fórmula:
(1)
Donde:
- Velocidad del perro relativo al barco, en kilómetros por hora.
- Velocidad del perro con respecto al observador, en kilómetros por hora.
- Velocidad del barco con respecto al observador, en kilómetros por hora.
Si sabemos que
y
, entonces la velocidad del perro con respecto al observador es:



El observador verá correr al perro sobre la cubierta del barco a una velocidad de 40 kilómetros por hora.
Can you give us a picture or something please!!
Answer:
A. less
Explanation:
The momentum of an object is directly proportional to it mass and velocity. It is the product of mass and velocity of the object. Given as

So the momentum of car,

Momentum of truck,

We know that, mass of car is less than that of truck and velocity of the two are same. It is implied that, momentum of car will be less than that of truck.
The centripetal force experienced by the towel is 55 N.
The given parameters;
- angular speed of the washing machine, ω = 200 rpm
- radius of the machine' drum, r = 0.5 m
- mass of the towel, m = 0.25 kg
The centripetal force experienced by the towel spinning along the walls of the drum is calculated as follows;
Fc = mrω²
where;
<em>Fc is the centripetal force</em>
<em>ω is angular speed in rad/s</em>
The angular speed in rad/s is calculate as;

The centripetal force experienced by the towel is calculated as;

Thus, the centripetal force experienced by the towel is 55 N.
