2.392 hector liters is equal to 239.2 liters
In a simple pendulum with no friction, mechanical energy is conserved. Total mechanical energy is a combination of kinetic energy and gravitational potential energy. As the pendulum swings back and forth, there is a constant exchange between kinetic energy and gravitational potential energy.
Answer:
Explanation:Digestive juices secreted by various organs such as salivary glands in the mouth, stomach, liver and pancreas help in the process of digestion of food. Saliva secreted by the salivary glands in the mouth aids in the breakdown of starch present in the food to simple sugar
Answer: 18.81m/s^2
Explanation:
Given the following :
Height of building = 0. 1 km = 100m
Horizontal distance = 85m
Using the equation :
S = 1/2gt^2
And S = 100, g = 9.8m/s^2
100 = 0.5(9.8)(t^2)
100 = 4.9(t^2)
t^2 = (100 / 4.9)
t^2 = 20.408
t = 4.5175214
t = 4.52s
Therefore, initial velocity of ball in horizontal direction;
Using the equation:
S = ut + 0.5at^2
a in horizontal direction = 0
Therefore,
S = ut
85 = u × 4.52
u = (85 / 4.52)
u = 18.805
u = 18.81m/s
