You redo the primitive yo yo experiment (Figure 1), but instead of holding the free end of the string stationary, you move your

hand vertically so that the tension in the string equals 2M /3. What is the vertical acceleration of the yo yo's cena of mass? Does it accelerate upward or downward? Express your answer to three significant figures and include the appropriate units. Enter positive value of the acceleration is directed upward and negative value if the acceleration is directed downward.

The vertical acceleration of the yo yo cent  of mass is 0.66 m/s².

We know that, T = M*a

And T is given as 2M/3

2M/3 = M*a

So, a = 0.66 m/s²

What is Acceleration ?

Acceleration is the general term for any process where the velocity changes. There are only two ways to accelerate either by increasing the speed or decreasing direction, or both. The reason for this is that velocity includes both a speed and a direction.

You cannot possibly be accelerating if you don't also change you direction and speed, regardless of how swiftly you are travelling. Due to this, a jet experiences no acceleration even when it is moving at a high speed. In this case, 800 miles per hour, because its velocity is constant.

When it lands, the jet will accelerate as it slows down and quickly come to a stop.

A industrial (large) pressure cooker operates at 275 kPa. Initially there is 10 kg of water at 20°C, the cooker is operated unt
alex41 [277]

Answer:

Q_{in} = 25349.92\,kJ

Explanation:

Let establish a control volume in the industrial pressure cooker, which is a transient state system. From the First Law of Thermodynamics, the heating process is modelled:

Q_{in} + m_{1}\cdot h_{1} - m_{2}\cdot h_{2} = (m_{1}-m_{2})\cdot u_{2} - m_{1}\cdot u_{1}

The heat transfered to the cooker is:

Q_{in} = m_{2}\cdot h_{2} - m_{1}\cdot h_{1} + (m_{1}-m_{2})\cdot u_{2}-m_{1}\cdot u_{1}

Properties at each state are described below:

State 1

u_{1} = 83.913\,\frac{kJ}{kg}

h_{1} = 83.915\,\frac{kJ}{kg}

State 2

u_{2} = 2540.1\,\frac{kJ}{kg}

h_{2} = 2720.9\,\frac{kJ}{kg}

The heat transfered to the cooker is:

Q_{in} = (9\,kg)\cdot (2720.9\,\frac{kJ}{kg} ) - (10\,kg)\cdot (83.915\,\frac{kJ}{kg} ) + (1\,kg) \cdot (2540.1\,\frac{kJ}{kg} )-(10\,kg)\cdot (83.913\,\frac{kJ}{kg} )

Q_{in} = 25349.92\,kJ

densk [106]

Answer:

Minutes can provide us the continuous data as we can have the values between the two minutes, in fraction. So if we consider minutes there will be a complete continuous data for the analysis. However the number of cars, trucks, pedestrians, bicyclists, food trucks etc will be in integers as they can not be described in terms of fractions. So for continuous data option (E) is correct.

The number of minutes for a car to get from the intersection to the administration building.
