Answer:
The bowling ball
Explanation:
The kinetic energy of an object is given by:
where
m is the mass of the object
v is its speed
In the problem, all the balls have same speed v: so their difference in kinetic energy will depend on their mass only.
We don't know the exact masses of the balls, however we can assume that the bowling ball has the largest mass among them: therefore, the bowling ball will also have the greatest kinetic energy.
Answer:
The area of the portion of the wall that will be painted is 105 square feet
Explanation:
Total area of wall = 12 × 10 = 120 ft²
The area of the wall that will not be painted = area of the blackboard = 5 × 3 = 15 ft²
So, the area of the wall to be painted = Total area of wall - Area of the wall that will not be painted = 120 - 15 = 105 ft²
Answer:1=C 2=A 3=B 4=E 5=G 6=G 7=A 8=E 9=C 10=A
Explanation:
A. The IV is the temperature of gas in the balloon.
B. The DV is the volume of the balloon.
This is because the temperature of the gas is the variable being manipulated in the experiment (Independent) and the volume is changing based on the shifts of the temperature (thus volume is Dependent).
