When the child jumps onto the merry-go-around the moment of inertia of the system changes. If we consider the child to be point-like mass then its moment of inertia would be:
We get the new moment of inertia by simply adding the child's moment of inertia to the old moment of inertia.
Since there is no force mention we must assume that angular momentum is conserved.
When we plug in all the numbers we get:
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.
A) Experiments. Opinion polls are used to study people, intuition and imagination are not official studies. Would appreciate brainliest!
Answer:
5
Explanation:
electrons can be more than det
Answer:
464.69 m
Explanation:
First car
Second car
Distance = Speed × Time
Here, the time taken and the distance traveled will be the same
Equating the two equations
So, the first would have to move 
in order to overtake the second car.
