The net force on the sled is 6.6 N pointing backwards, opposite to the direction it's sliding. That's why it's slowing down, and will eventually stop.
Answer:
See the answers below.
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
Vf = final velocity = 10 [m/s]
Vo = initial velocity = 40 [m/s]
t = time = 5 [s]
a = acceleration [m/s²]
Now replacing:
![10=40-a*5\\40-10=a*5\\30=5*a\\a=6[m/s^{2}]](https://tex.z-dn.net/?f=10%3D40-a%2A5%5C%5C40-10%3Da%2A5%5C%5C30%3D5%2Aa%5C%5Ca%3D6%5Bm%2Fs%5E%7B2%7D%5D)
Note: The negative sign in the above equation means that the velecity is decreasing.
2)
To solve this second part we must use the following equation of kinematics.
where:
x = distance [m]
![(10)^{2} =(40)^{2} -2*6*x\\100=1600-12*x\\12*x=1600-100\\12*x=1500\\x=125[m]](https://tex.z-dn.net/?f=%2810%29%5E%7B2%7D%20%3D%2840%29%5E%7B2%7D%20-2%2A6%2Ax%5C%5C100%3D1600-12%2Ax%5C%5C12%2Ax%3D1600-100%5C%5C12%2Ax%3D1500%5C%5Cx%3D125%5Bm%5D)
Answer:
The thyroid is a butterfly-shaped gland that sits low on the front of the neck.It plays a major role in the metabolism, growth and development of the human body
Explanation:
The physiologic function affected by altered thyroid function are:
1. It is likely that all cells in the body are targets for thyroid hormones
2. It stimulates diverse metabolic activities most tissues, leading to an increase in basal metabolic rate
3. Thyroid hormones are clearly necessary for normal growth
Thyroid hormones increases heart rate, cardiac contractility and cardiac output. They also promote vasodilation (widening of blood vessels), which leads to enhanced blood flow to many organs. Central nervous system: Both decreased and increased concentrations of thyroid hormones lead to alterations in mental state.
There do not seem to be organs and tissues that are not affected by thyroid hormones
Answer:
11.75 ohms
Explanation:
since its series connection
R equivalent = R1 + R2 = 7.25 + 4.5
