Answer:
Explanation:
a = 4ms⁻², Vf = 180 m/s & Vi = 140m/s
a =
4 = 
t = 40/4
t = 10sec
To Measure Distance Use third Equation of Motion:
2aS = Vf²-Vi²
S = 
S = 12800/8 = 1600m

i hope this helps!
Answer:
Explanation:stop it cause the sun don't shine that long unless if it's summer cause the summer time is very hot it may be 100 degrees or lower
Explanation:
The Coulomb's law states that the force acting on two charges is directly proportional to the product of charges and inversely proportional to the square of distance between them . Mathematically, it is given by

Where
k is the electrostatic constant
q₁ and q₂ are charges
r is the distance between them.
The SI unit of electric force is Newton. It can be attractive or repulsive. The attraction or repulsion depend on charges. If both charges are positive, the force is repulsive and if both are opposite charges, the force is attractive.
Answer:
HCI creates an acidic environment, which promotes the process of pepsin.
When that happens, pepsin is maximally active and works on a fully digestion of the presented protein.
On the other hand HCI prevents the activeness of the amylase, thereby only a small part of starch is digested.
Explanation:
The physiological significance of these effects are: salivary glands found in the mouth which has a neutral pH environment segregates amylase, meanwhile pepsinogen becomes pepsin thanks to the compatibility with this environment.
While pepsin is widely active at a lower pH inside the stomach, amylase activity, on the other hand decreases at lower pH environment.
