Sound travels through all mediums solid, liquid, and gas. Because sound is a vibration it will travel fastest through solids. This is because the vibrations that make up sound are carried from one place to another by neighboring molecules vibrating against one another. The density of the solid is higher than liquid and gas which means the molecules are more tightly packed and the vibration can pass from one to the next more quickly.
Answer:
C. L
Explanation:
Given that
Displacement of the object is given as
x = A sin(2 n f t)
We know that
Quantity Dimensions
Length/Amplitude L
Distance /Displacement L
Time T
Velocity LT⁻¹
Acceleration LT⁻²
Area L²
Mass M
Frequency T⁻¹
Given that x is the displacement that is why the dimensions of the displacement will be L.
Now by balancing the dimensions both sides ,the dimensions of the A will be L.
C. L
7200 grams is what equivalen to 7.s kilograms
Answer:
15N downwards
Explanation:
Net force is the sum of all forces acting on an object.
Taking upwards as positive and downwards as negative,
Net Force = 10N + (-25N)
= -15N
Hence <u>Net Force is 15N downwards</u>.
Answer:
Biotic factors are the living component of an environment while abiotic factors are the non living component of an environment.
Biotic factors of Mono lake include plants, animals, fungi, algae and bacteria
Abiotic factors of Mono lake include sunlight, temperature, moisture, wind or water currents, soil type, and nutrient availability.
While the biotic and abiotic factors on Land inhabited by humans including Me are :
Biotic factors-Plants ,animals, bacteria
Abiotic factors-Sunlight, heat/ temperature, Climate, weather, water sources.
