A spontaneous reaction is a term that is best describe to a type of reaction wherein it is started without even with the help of an outside force. In addition to that, this kind of reaction is commonly driven by the forces of enthalpy and entropy which are essential concepts to thermodynamics.
<span>Adenosine triphosphate (ATP) consists of an adenosine molecule bonded to three phophate groups in a row. In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. This occurs when a molecule of adenosine diphosphate (ADP) uses the energy released during cellular respiration to bond with a third phosphate group, becoming a molecule of ATP. So the energy from cellular respiration is stored in the bond between the 2nd and 3rd phosphate groups of ATP. When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work. Now its back to being ADP and is ready to store the energy from respiration by bonding with a 3rd phosphate group. ADP and ATP constantly convert back and forth in this manner.

Answer:
the power of the gravitational force depends on the factors
mass and the distance
Explanation:
Answer:
Option d is correct.
The magnitude of the resultant force upon the piling = 2930 lbs.
Explanation:
Resultant of a group of forces = vector sum of the forces.
Force 1 = (-1250î) lbs
Force 2 = (2650j) lbs
Resultant = (-1250î + 2650j) lbs
The magnitude of the resultant = √[(-1250)² + (2650)²] = 2930 lbs.
Or in visualization method, the two forces presented form a right angled triangle with the resultant of the two forces.
Hence, using Pythagoras theorem,
F₁² + F₂² = R²
(1250)² + (2650)² = R²
R = √[(1250)² + (2650)²] = 2930 lbs.
Answer:
2960 N
Explanation:
Convert rev/min to rad/s:
150 rev/min × (2π rad/rev) × (1 min / 60 s) = 50π rad/s
Sum of forces in the centripetal direction:
∑F = ma
T = m v² / r
T = m ω² r
T = (0.2 kg) (50π rad/s)² (0.6 m)
T = 2960 N
