Answer:
Concrete
Explanation:
The speed at which sound propagates is medium dependent. As one of the forms of mechanical waves, sound requires a material medium for propagation from place to place.
- Sound travels with the least speed in air because air particles are far apart and they are randomized.
- Sound travels with the greatest speed in solids. Concrete is the only solid material given in the choice.
The speed of sound increases from air to liquid and to solid.
In normal cells, the cell cycle is controlled by a complex series of signaling pathways by which a cell grows, replicates its DNA and divides.
In cancer, as a result of genetic mutations, this regulatory process malfunctions, resulting in uncontrolled cell proliferation.
What statement best describes what it means to maximize your efforts in sports?

Answer:
The horizontal distance d does the ball travel before landing is 1.72 m.
Explanation:
Given that,
Height of ramp 
Height of bottom of ramp 
Diameter = 0.17 m
Suppose we need to calculate the horizontal distance d does the ball travel before landing?
We need to calculate the time
Using equation of motion




We need to calculate the velocity of the ball
Using formula of kinetic energy



Using conservation of energy



Put the value into the formula


We need to calculate the horizontal distance d does the ball travel before landing
Using formula of distance

Where. d = distance
t = time
v = velocity
Put the value into the formula


Hence, The horizontal distance d does the ball travel before landing is 1.72 m.
This is one method of how infectious diseases like skin infections spread. Keeping the gym clean is essential to maintaining everyone's health and safety.
<h3>Which skin illness is the worst?</h3>
Necrotising fasciitis is just a severe infection of the skin, including tissue beneath the skin, and the fascia (the fibrous tissue that divides muscles and organs), which causes necrosis, or the death of tissue. If not identified and treated promptly, the infection spreads quickly, is lethal.
<h3>A skin infection: how do you treat it?</h3>
Depending on the infection's origin and intensity, different treatments are available. It may take days or weeks for some viral skin infections to heal on their own. Antibiotics taken orally or administered topically to the skin are frequently used to treat bacterial infections.
