The magnitude of the Earth's acceleration is 
Explanation:
First of all, we start by calculating the magnitude of the force exerted by the apple on the Earth. According to Newton's third law, this is equal to the force exerted by the Earth on the apple, which is the weight of the apple, given by:
where
m = 0.43 kg is the mass of the apple
is the acceleration of gravity
Substituting,
Now we can find the Earth's acceleration by applying Newton's second law:
where:
F = 4.2 N is the net force exerted by the apple on the Earth
is the mass of the Earth
a is the Earth's acceleration
And solving for a, we find:

Answer : The mass of cereal in two units are, 34.815 oz and 978.075 grams respectively.
Explanation :
As there are two systems for measuring the units which are English and Metric system.
The Metric System measured the things in meters, grams, liters, etc and adds prefixes like kilo, milli and centi to the count orders of the magnitude.
The English system measured the things in feet, inches, pounds, mile, etc.
As we are given the mass of cereal in 978 grams that means 987 grams is in metric unit. Now we have to convert metric unit into English unit.
Conversion factor used : (1 oz = 28.350 g)
As, 28.350 grams = 1 oz
So, 987 grams = 
= 34.815 oz
As we are given the mass of cereal in 34.5 oz that means 34.5 oz is in metric unit. Now we have to convert metric unit into English unit.
Conversion factor used : (1 oz = 28.350 g)
As, 1 oz = 28.350 grams
So, 34.5 oz = 
= 978.075 grams
Therefore, the mass of cereal in two units are, 34.815 oz and 978.075 grams respectively.
Sum of the individual forces
Answer:
Nuclear Reaction
Explanation:
Technically fusion and fission should be included, but a nuclear reaction includes both fusion and fission, so it must be the answer.
