Explanation:
Mrs. Lynn's art class is making pencil holders out of soup cans
These soup cans are definitely in cylindrical forms.
Each student is first covering a can with felt.
A felt is a type of material that is used for covering other objects. Here a felt is used to cover soup cans.
So if the diameter of the bottom of the can is 8 cm (i.e d = 8cm)
What will the circumference of the piece of felt need to be in order to cover the bottom of the can?
The felt will also take the circumference of a cylinder; and which is given by the expression
C = 2 πr
since diameter (d) = 8 cm
radius (r) = 
r = 
r = 4 cm
C = 2 × π × 4 cm
C = 2 × 3.142 × 4 cm
C = 25.13 cm
∴ the circumference of the piece of felt need to be 25.13 cm in order to cover the bottom of the can.
The flower absorbs all light but purple, making it appear, purple!
The correct answer is B. 24 N.
To figure out the exact force the cart exerts on the woman, we have to use Newton's third law of motion. Newton's third law of motion states that every action has an equal and opposite reaction. This means that if object 1 exerts a force on object 2 , object 2 will exert an equal but opposite force on object 1.
This law allows us to ignore the masses of the chart and the women and focus on the pairs of forces the woman and the chart apply to each other. Since the woman exerts a force of 24 N on the chart, the chart will exert a force of 24 N on the woman.
The correct answer is B. 24 N.
Answer:
Explanation:
The two major defects of simple electric cells causes current supplied to be for short time. These defects are: polarization and local action.
a. Polarization: This is a defect caused by an accumulation of hydrogen bubbles at the positive electrode of the cell. It can be prevented by the use of vent, using a hydrogen absorbing material or the use of a depolarizer.
b. Local Action: This is the gradual wearing away of the electrode due to impurities in the zinc plate. It can be controlled by the amalgamation of the zinc plate before it is used.
