The normal force is 2820.48N in the negative y direction.

<h3>According to Newton's second law of motion, </h3>

Force = mass × acceleration

F = m×A

Note that rocket takes off from Earth's surface, accelerating straight up at 31.2 m/s² .

The rocket accelerates upwards, hence the acceleration will be negative because it defies gravity's law (it keeps going into space without coming down)

Acceleration of the rocket = -31.2m/s²

Mass of the astronaut = 90.4kg

Normal force acting on the astronaut = -31.2 × 90.4kg

                                                                 = -2820.48N

Therefore, the normal force is 2820.48N in the negative y direction.

The flow control circuit design that can best control an overrunning load is the ____ circuit.
lara31 [8.8K]

The meter out circuit is the flow control circuit design that can most effectively control an overrunning load.

The meter-out circuit can be very accurate, but are not efficient. The meter-out circuit can control overrunning as well as opposing loads while the other one method must be used with opposing loads only. The choice of flown control valve method and the location of the flow control in the circuit are dependent on the type of application being controlled.

<h3>What is a Circuit ?</h3>

In electronics, a circuit is a complete circular conduit through which electricity flows. A simple circuit consists of conductors, a load, and a current source. The term "circuit" broadly refers to any continuous path via which electricity, data, or a signal might flow.

  • The directional valve shifts, causing the actuator to move faster than pump flow can fill it due to an overrunning load. Oil is leaking from one side, whereas there is none on the other.

Hence, flow control circuit design that can best control an overrunning load is the opposing circuit

The half-life of a certain isotope is 15 minutes. How much of a 400 g sample will remain after 90 minutes?12.5 g6.25 g26.7 g66.7
Virty [35]

There is a total of 6 half lives that need to take place.


ONE HALF LIFE = 200

TWO HALF LIFES = 100

THREE HALF LIFES  = 50

FOUR HALF LIFES = 25

FIVE HALF LIFES = 12.5

SIX HALF LIFES = 6.25


The answer is 6.25g

hallar un numero de dos cifras sabiendo que la suma de las cifras es 12 y que la primera de ellas es el triple de la segunda
Natali [406]

Answer:

93 o 39.

Explanation:

Hola.

En este caso, podemos resolver este problema por medio del planteamiento de las siguientes ecuaciones:

1. Definimos <em>x</em> como el primer dígito y <em>y</em> como el segundo, por lo tanto, como su suma es 12, escribimos:

<em>x</em> + <em>y</em> = 12

2. Ahora, dado que el primer dígito, x es el triple del segundo, escribimos:

<em>x</em> = 3 <em>y</em>

De este modo, podemos resolver para <em>y</em>:

3 <em>y</em> + <em>y</em> = 12

4 <em>y</em> = 12

<em>y</em> = 12 / 4

<em>y</em> = 3

Y para <em>x</em>:

<em>x</em> = 3 <em>y</em>

<em>x</em> = 3 * 3

<em>x</em> = 9

Así, el número puede ser 93 o 39.

¡Saludos!

A wheel on a watermill turns halfway every 4.0 s. What is the wheel's angular velocity?
Doss [256]
A revolution equals 2*pi radians.
 As the wheel rotates half every 4 seconds, then it means that it rotates half revolution.
 Thus, the angular velocity of the wheel is given by:
 w = (pi) / (4) = 0.79 rad / sec
 answer
 The wheel's angular velocity is 0.79 rad / sec
