Answer:
there are 5 main aspects of personal health: physical, emotional,social,spiritual, and intellectual.
physical weelness indicates a high levelnof endurance, flexibility and strength. it incorporates daily exercise through cardiovascular and muscular activities.
mental or emotional wellness focuses on an acceptance and afreement with one's emotions and feelings. A person need to reach a high level of self-respect and dignoty.
lifestyle wellness doesn't have a definite, agreed upon route or direction for accomplishment. lifestyle wellness incoporates many different dimentions of wellness. but deals mostly with having a balanced lifestyle. every person has a different idea of what a balanced idea includes.
intellectual wellness encourages us to engage in creative and mentallu-stimulating activities. these activities should expand ur knowledge and skills while allowing you to share ur knowledge and skills with others. intellectual knowledge includes learning. its important to explore new ideas and understanding in order to become more mindful and better-rounded. having an optimal level of intellectual wellness inspires exploration. also stimulates curiosity.
Answer:
d=1.07m
Explanation:
Calculate Initial Kinetic Energy:
KE = 1/2*m*v^2
KE= 0.5*(10.3kg)*(1.64m/s)^2 = 13.85J
Calculate work overcoming friction:
W = F*d = mu*m*g*d
W = (0.128)*(10.3kg)*9.80m/s^2)*d
W = 12.92*d
Equate the two since all of the kinetic energy is used up in working against friction:
W = KE
12.92d = 13.851J
Solve for d:
d= (13.851J)/(12.92) = 1.07 m
<u>Answer:</u> The specific heat of ice is 2.11 J/g°C
<u>Explanation:</u>
When ice is mixed with water, the amount of heat released by water will be equal to the amount of heat absorbed by ice.
The equation used to calculate heat released or absorbed follows:
![m_1\times c_1\times (T_{final}-T_1)=-[m_2\times c_2\times (T_{final}-T_2)]](https://tex.z-dn.net/?f=m_1%5Ctimes%20c_1%5Ctimes%20%28T_%7Bfinal%7D-T_1%29%3D-%5Bm_2%5Ctimes%20c_2%5Ctimes%20%28T_%7Bfinal%7D-T_2%29%5D)
......(1)
where,
q = heat absorbed or released
= mass of ice = 12.5 g
= mass of water = 85.0 g
= final temperature = 22.24°C
= initial temperature of ice = -15.00°C
= initial temperature of water = 25.00°C
= specific heat of ice = ?
= specific heat of water = 4.186 J/g°C
Putting values in equation 1, we get:
![12.5\times c_1\times (22.24-(-15))=-[85.0\times 4.186\times (22.24-25)]](https://tex.z-dn.net/?f=12.5%5Ctimes%20c_1%5Ctimes%20%2822.24-%28-15%29%29%3D-%5B85.0%5Ctimes%204.186%5Ctimes%20%2822.24-25%29%5D)
Hence, the specific heat of ice is 2.11 J/g°C
Answer:
The correct answer will be-
1. Allows scientists to replicate experiments
2. Tests only one variable at a time
3. Plans how to record data so they can be published
Explanation:
A scientific experiment is performed to test the hypothesis which represents the limited explanation of the phenomenon.
The experiment is designed in a way that it test one variable at a time like the growth of plants. The experiment must be designed in a way that it can be replicated to reduce the error and repeated by other scientific persons to support the experiment. The design includes the plan for recording the results as it is one of the steps of the scientific method.
Thus, the selected options are the correct answer.
Controlled experiment is the type of experiment that involves changing only one variable at a time. Controlled experiment is subtly defined as an experiment which holds everything constant except one particular variable. This type of experiment allows only one variable to ever change at a given time
