F=ma (Newton's second law of motion).
Then,
a = F/m = Uk*mg/m = Uk*g = 0.0751*9.81 = 0.737 m/s^2 (should be negative since a deceleration is expected).
v = Sqrt (u^2-2ad), Where v = final velocity, u=initial velocity, a = acceleration, d = distance moved.
Therefore,
v^2-u^2 = -2ad => d = (v^2-u^2)/-2a = (2^2-3.18^2)/-2*0.737 = 4.15 m
Drinking water helps maintain nearly all processes of the human body and <em>homeostasis. </em>Further, drinking water helps,
- Digestion
- Absorption
- Circulation
- Saliva and mucus production
- Thermoregulation/homeostasis
- Lubrication of joints
- Boosts integumentary health.
- Helps in excretory systems
- Prevents dehydration of cells
- Reduces chance of hangover from alcoholic drinks.
- etc,
Succinctly, it is VERY important to drink water! Water is the source of human life and without water, we cannot survive.
Answer:
3743.489 kg
Explanation:
F_g = 591 N
G = 6.674x10^-11 constant of gravity
m_1 = 95 kg
m_2 = unknown
r = 4990*1000 =
F_g = G[(m_1*m_2)/r^2]
591 N = 6.674x10^-11[(95*m_2)/4990^2]
8.855 = [(95*m_2)/4990^2]
355631.472 = 95*m_2
m_2 = 3743.489 kg
Answer:
(a) 
(b) 
Solution:
As per the question:
Mass of the object, m = 1.30 kg
Length of the rod, L = 0.780 m
Angular speed, 
Now,
(a) To calculate the rotational inertia of the system about the axis of rotation:
Since, the rod is mass less, the moment of inertia of the rotating system and that of the object about the rotation axis will be equal:
(b) To calculate the applied torque required for the system to rotate at constant speed:
Drag Force, F =
