The circumference of a circle with a diameter of 10 cm is 31.4cm.
The circumference of a circle is its edge or the measurement of its entire arc.
The circumference of a circle with radius 
is 
.
The circle in question has a diameter of 10 cm.
The radius of a circle's diameter is equal to its length divided by two. Consequently, the given circle's radius is 5 cm.
If we assume that π=3.14, then the given circle's circumference will be equal to 2×π×5. Consequently, 31.4 cm is the required circumference.
As a result, a circle with a diameter of 10 cm has a 31.4 cm circumference and it has been expressed in three significant figures.

The correct answer would be A. The forces are equal.
When liquid cools, both its density and volume increases. Therefore the answer to your question are #s 1 and 5. This is due to the fact that molecules which are compacted or pressed against each other form a solid, and when they start to cool-down the molecules start to break free from each other increasing the density of a liquid and the space that it occupies.
Answer:
Explanation:
simple, just use F = ma
assume that the acceleration is any positive value <em>a</em>
The force F must accelerate both sleds
F = (2m + m)<em>a</em>
The force T must accelerate the rear sled
T = m<em>a</em>
T/F = m<em>a</em>/3m<em>a</em> = 1/3
Answer:
9.44 eV
Explanation:
q = Amount of charge = 86.3 μC = 86.3 x 10⁻⁶ C (Since 1 μC = 10⁻⁶ C)
V = Electric potential of the charge = 17.5 Volts
U = Amount of electric potential energy carried by charge
Amount of electric potential energy carried by charge is given as
U = q V
Inserting the values
U = (86.3 x 10⁻⁶) (17.5)
U = 0.00151 J
U = 
U = 9.44 eV
KE = Kinetic energy the charge could have
Using conservation of energy
KE = U
KE = 9.44 eV
