Answer:
4752 ft/min.
Explanation:
The following data were obtained from the question:
Speed (in mph) = 54 mph
1 mile = 5280 feet
1 hour = 60 minutes
Speed ( in ft/min) =?
Next, we shall convert 54 mph to ft/h. This can be obtained as follow:
1 mph = 5280 ft/h
Therefore,
54 mph = 54 mph × 5280 ft/h / 1 mph
54 mph = 285120 ft/h
Finally, we shall convert 285120 ft/h to ft/min. This can be obtained as follow:
1 ft/h = 1/60 ft/min
Therefore,
285120 ft/h = 285120 ft/h × 1/60 ft/min / 1 ft/h
285120 ft/h = 4752 ft/min
From the calculations made above, 54 mph is equivalent to 4752 ft/min.
Answer:
The formulas that will be used are:
Situation one:
The moon will be experiencing gravitational force in the form of centripetal force, so we equate the two formulas.
Gravitational force = GMm /r²
Centripetal force = mv²/r
Equating,
GMm/r² = mv²/r
v² = GM/r
The first scenario will use the formula v² = GM/r
Situation 2:
The second situation will use the simple distance over time formula for velocity, where the distance will be the circumference and the time will be in seconds.
v = 2rπ/t

Answer:
C. Chemical Bonds are broken
Explanation:
A chemical reaction occurs when chemical bonds are broken.
Chemical reactions occur when chemical bonds between atoms are formed or broken.
Hope this helps :)
In an atom, the nucleus is composed of positive charged particles called protons and neutrons that have zero charge. Most of the mass of the atom is in the nucleus. The atom is surrounded by orbits of electrons that are mobile and are negatively charged.
