Answer:
T = 4.905[N]
Explanation:
In order to solve this problem we must perform a sum of forces on the vertical axis.
∑Fy = 0
We have two forces acting only, the weight of the body down and the tension force T up, as the body does not move we can say that it is system is in static equilibrium, therefore the sum of forces is equal to zero.
A B
input force the force exerted on a machine
work input the work done on a machine as the input force acts through the input distance
output distance the distance an output force acts through a machine
mechanical advantage the number of times that a machine increases an input force
Answer:
Explanation:
average speed is distance traveled over time
v = (50 + 30(1.5)) / (2 + 1.5) = 27.1428571...
v = 27 km/hr
Power = voltage x current. Voltage = Power/current = 100/0.8 = 125volts.
Answer: A gland is an organ which produces and releases substances that perform a specific function in the body.
Explanation: <em>A gland is an organ which produces and releases substances that perform a specific function in the body. There are two types of gland. Endocrine glands are ductless glands and release the substances that they make (hormones) directly into the bloodstream.</em>
