Answer:

Explanation:
Given that:
- moment of inertia of tucked body,

- rotational speed of the body,

- i.e.

- moment of inertia of the straightened body,

<u>Now using the law of conservation of angular momentum:</u>
angular momentum of tucked body=angular momentum of straight body



Answer with Explanation:
We are given that
Power of toaster=
Power of electric frying pan=
Power of lamp=
Current in circuit=15 A
Potential difference= V=120 V
We know that
Current=
Using the formula
Current drawn by toaster=
Current drawn by electric frying pan=
Current drawn by lamp=
The equal velocity approach for duct size assumes that the air velocity in each duct segment is the same.
How fast is the air moving through a duct?
The most common unit of air velocity (distance traveled in a unit of time) is feet per minute (FPM). The amount of air passing past a location in the duct per period of time may be calculated by multiplying the airflow by the area of the duct. The standard unit for volume flow is cubic feet per minute (CFM).
What happens when the size of ducts changes to the airflow?
- Result for an image The equal velocity technique for duct size makes the assumption that air velocity is constant across the entire duct system.
- The main lesson to be learned from this is that when air goes from a bigger to a narrower duct, its velocity rises. The velocity drops when it transitions from a shorter to a bigger duct. The flow rate or the amount of air passing through the duct in cubic feet per minute is the same in all scenarios.

Answer:
Speed = 10.24 m/s.
Explanation:
<u>Given the following data;</u>
Distance = 100m
Time = 9.77
To find her speed;
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;

Substituting into the equation, we have;

<em>Speed = 10.24 meter per seconds. </em>
whether or whether the conclusions apply to people whose location and circumstances differ from those of the study's participants need to asked to ensure both the external and internal validity of your results
<h3>How can external validity be guaranteed?</h3>
Broad inclusion criteria that produce a study group that more closely mimics real-life patients and, in the case of clinical trials, selecting interventions that are practical to implement can both boost external validity.
<h3>What steps would you take to make sure your study is reliable and valid?</h3>
The development of a solid study design, the selection of suitable methodologies and samples, and the meticulous and consistent execution of the research are all necessary for the reliability and validity of your findings.
