I looked it up but got perihelion so I don't know if that will help at all but try um.... I don't know try L
Explanation:
The momentum of an object is given by:
p = mv
m is the object's mass and v is its velocity.
Given values:
m = 15kg
v = 25m/s
Plug in the values and solve for p:
p = 15*25
p = 375kg×m/s
Answer:
the answer is A
Explanation: The vertical temperature line indicates no change in temperature at those altitudes.
The correct choice is Buffers.
Buffers contains both acids and bases in equilibrium.when base is added to buffers, they adjust the pH value by releasing hydrogen ions.when acid is added to buffers, they adjust the pH value by consuming hydrogen ions. hence these substances resist any change in their pH value by releasing or absorbing hydrogen ions.This process keeps the pH value constant.
