A water jet that leaves a nozzle at 60 m/s at a flow rate of 120 kg/s is to be used to generate power by striking the buckets lo

Answer:

d

Explanation:

Answer:

1. The force applied by the shelf supporting the book.

Explanation:

The free body diagram for the book is represented as follows:

1 - The weight of the book acting downward

2 - The normal force exerted by the shelf upward on the book.

As the book remains stationary, these two forces balance each other, and in accordance with Newton's Third Law, the reactive force equivalent to gravity is opposite and equal to the weight of the book. This reaction force prevents the book from falling off the shelf.

<span>Conclusion: The door's weight results in a CCW torque which can be calculated as Tccw = 145 N*3.13 m / 2. You require a CW torque that balances this Tcw = F*2.5 m*sin20</span>

Answer:

b. 9.5°C

Explanation:

= Ice mass = 50 g

= Initial temperature of water and aluminum = 30°C

= Latent heat of fusion =

= Water mass = 200 g

= Water's specific heat = 4186 J/kg⋅°C

= Aluminum mass = 80 g

= Aluminum's specific heat = 900 J/kg⋅°C

The equation governing heat exchange in the system is presented by

The final equilibrium temperature calculates to 9.50022°C

Vf=Vi+at=15m/s+(3.5m/s^2)(11s)=53.5m/s
