Answer:
464.3 N
Explanation:
Given parameters are:
I = 0.065 
L = 0.025 m
R = 0.28 m
= 0 m/s
= 5 m/s
t = 0.1 s
Hence, 
We must connect two torque equations to find the answer.
Where 
Hence, 
Thus, 
N
Answer:
The longest wavelength of light is 209 nm.
Explanation:
Given that,
Spring constant = 74 N/m
Mass of electron 
Speed of light 
We need to calculate the frequency
Using formula of frequency
Where, k= spring constant
m = mass of the particle
Put the value into the formula
We need to calculate the longest wavelength that the electron can absorb
Where, c = speed of light
f = frequency
Put the value into the formula
Hence, The longest wavelength of light is 209 nm.
THE answer the table is holding the book up would be a normal force
This question is incomplete because the options are not given; here is the complete question:
Cardiorespiratory fitness improves the efficiency of the cardiovascular and the respiratory systems in delivering oxygen to the body.
Please select the best answer from the choices provided.
True
False
The correct answer to this question is True
Explanation:
The cardiorespiratory system (cardiovascular and respiratory system) includes structures and organs such as the heart, the lungs, the veins, etc. that are involved in the process of oxygenation of the body. This process can be less or more efficient depending on different factors. One of these is the cardiorespiratory fitness or the ability of the body to work effectively in terms of oxygenation during exercise or effort.
In this context, a higher cardiorespiratory fitness means the cardiorespiratory system will work more efficiently, while low fitness implies less efficient oxygenation. Additionally, this fitness can be improved through activities such as running, hiking, among others. Therefore, cardiorespiratory fitness improves efficiency in the process of oxygenation, which makes the statement true.
