Explanation:
The given data is as follows.
= 57 kg, 
= 79 kg
= 6.5 m, 
= (6.5 - 1.9) m = 4.6 m
(a) The sum of torque ends about far end is as follows.
= 0
= 0
T = 828 N
Therefore, 828 N is the tension in the cable closer to the painter.
(b) Now, we will calculate the sum about close ends as follows.
= 0
T= 506 N
Therefore, 506 N is the tension in the cable further from the painter.
Answer:
A) True. The droplets will move in parabolic arcs.
Explanation:
When the dog shakes the drops that leave the fur they leave with a speed and an angle; These are now subject to the out of gravity that accelerates them in the vertical axis and has no outside the horizontal axis, so they must describe a parabolic movement.
Pair to describe a central force that changes its speed, but this force does not exist once they leave the dog
Let's check the answers
A) True. You agree with the analysis
B) False. There is an outside on the axis and therefore the line is deviating
C) False. There is no radial force that creates this movement
Answer:
Explanation:
The tension in a cable is given by:
Where 
is the mass density of the cable and v is the speed of the cable's pulse. These values are defined as:
The pulse makes four trips down and back along the cable, so 
Replacing (2) and (3) in (1), we calculate the tension in the cable:
It seems reasonable to assume that the car is standing still while the sand is pouring in. Since its speed is zero, it has no momentum, and that won't change until it starts moving, no matter how much sand has been loaded onto it.
