Answer:
The majority of chemical digestion occurs in the small intestine. Digested chyme from the stomach passes through the pylorus and into the duodenum.
The maximum height reached by the water before it starts coming back down is 40 m.
<h3>
Maximum height reached by the water</h3>
The maximum height reached by the water before it starts coming back down is calculated by applying the principle of conservation of energy.
P.E = K.E
mgh = ¹/₂mv²
gh = ¹/₂v²
h = (v²)/(2g)
h = (28²)/(2 x 9.8)
h = 40 m

Answer:
Electric potential, 
Explanation:
It is given that,
The magnitude of electric field, 
Distance between automobile engines that consists of metal conductors, 
Let V is the magnitude of the potential difference between the conductors. The relation between the electric field and the electric potential is given by:
So, the magnitude of the potential difference between the conductors is 
. Hence, this is the required solution.
A stationary charge is located between the poles of a horseshoe magnet. The magnetic force exerted by the charge is zero.
<h3>What is charge?</h3>
Charge is the physical property of matter which cause a particle to attract or repel when placed in its field.
A stationary charged particle does not interact with a static magnetic field. A charge placed in a magnetic field experiences a magnetic force. There will be no magnetic force acting on a stationary charge. The charge must be moving in order to have magnetic force on it.
Thus, the magnetic force exerted by the charge is zero.
