Answer:
Scenario 1 will cause the sound of the drumstick hitting the metal bar to reach your ears in the least amount of time.
Explanation:
The sound wave will travel faster in the metal bar than through the air because the speed of sound waves in solids is faster than it is in gases.

Therefore if two objects were held at the same height, the object with more mass(the heavier object) will fall faster because it's gravitational potential energy is greater than that of the lighter object

The cross-sectional area of the copper wire is which has 1.3 ohm at 20 degree Celsius during laboratory experiment by student is 7.9×10⁻⁸ ohm.
What is the resistance?
Resistance is obstacle for the current flow in the circuit. It is the measure of reverse act to current flow in through a material. It can be given as,
Here, (ρ) is the specific resistance (l) is the length of the wire and (A) is the cross-sectional area of the wire.
During a laboratory experiment, the student finds that at 20° Celsius, a 6.0-meter length of copper wire has a resistance of 1.3 ohms.
The value of resistivity of copper wire is 1.72×10⁻⁸ ohm-m. Put these values in the above formula as,
Thus, the cross-sectional area of the copper wire is which has 1.3 ohm at 20 degree Celsius during laboratory experiment by student is 7.9×10⁻⁸ ohm.
Learn more about the resistance here;
ρ = resistivity of copper at 20 °C = 1.72 x 10⁻⁸ ohm-m
R = resistance of the copper wire = 1.3 ohm
L = length of the copper wire = 6 meter
A = area of cross-section of the copper wire = ?
Resistivity of copper wire is given as
R = ρL/A
inserting the values in the above equation
1.3 = (1.72 x 10⁻⁸) (6)/A
A = 7.9 x 10⁻⁸ m²
Hence the correct choice is
(1) 7.9 x 10⁻⁸ m²
B. the rate of evaporation of a fluid
C. how much energy it takes to warm a fluid
D. the density of a fluid
E. a fluid's resistance to flowing
Answers
Answer:
E. a fluid's resistance to flowing
Explanation:
Viscosity, also known as "thickness" is a rheological property that describes a fluid's resistance to flowing, fluids of low viscosity, like water, flow more easily while high viscosity fluids, like mud, are harder to move through. It is an important property because it determines the energy required to make a certain fluid flow.

Glare are usually light vibrations in all directions, but the filter reduces the glare by allowing only light vibrations in a particular direction to pass through it, and hence cutting off other vibrations. Hence the glare becomes reduced.
