Explanation:

TRUE

Your eyes detect electromagnetic waves that are roughly the size of a virus. Your brain interprets the various energies of visible light as different colors, ranging from red to violet. ... On the other end of the spectrum are gamma rays, with wavelengths billions of times smaller than those of visible light

Teeth are an example of which type of simple machine? lever wedge inclined plane pulley
andreev551 [17]

Answer: Teeth is an example of a wedge.

Explanation :

the machines that make our work easier are called simple machines. Some machines can be compound because they are a combination of more than two simple machines. For example, stapler.

Teeth are an example of a wedge. It is a simple machine which consists of two inclined planes. It is used to split apart objects.  

The mechanical advantage of a wedge is more than 1.

So, the correct option is (b) " Wedge".

The time taken for the tiny saliva to travel is 0.55 second.

The  horizontal distance traveled at speed of 4 m/s is 2.2 m.

The horizontal distance traveled at speed of 20 m/s is 11 m.

<h3>Time of motion of the tiny saliva</h3>

The time taken for the tiny saliva to travel is calculated as follows;

h = vt + ¹/₂gt²

where;

  • v is initial vertical velocity  = 0
  • g is the acceleration due to gravity

h = 0 + ¹/₂gt²

h = ¹/₂gt²

2h = gt²

t² = 2h/g

t = √(2h/g)

Substitute the given parameters and solve for time of motion;

t = √(2 x 1.5 / 10)

t = 0.55 second

<h3>Horizontal distance traveled at speed of 4 m/s</h3>

X = Vx(t)

X = (4 m/s)(0.55)

X = 2.2 m

<h3>Horizontal distance traveled at speed of 20 m/s</h3>

X = (20)(0.55)

X = 11 m

Which is true regarding diffusion and osmosis? Question 3 options:
Scilla [17]

Answer:

Option (A)

Explanation:

Diffusion is defined as the transfer of particles such as ions or molecules from a higher concentration region to a lower concentration region.

Osmosis is a special type of diffusion in which the solvents such as water are allowed to move from a region of higher to a lower concentration through a layer of a semi-permeable membrane. This is an energy-independent process and occurs along the concentration gradient.

Thus, the correct answer is option (A) that is true for both osmosis and diffusion.

What is the difference in PE
Blababa [14]

Answer:

831.4 J

Explanation:

Info given:

mass adult: 82.5kg

mass child: 14.7kg

height of wall: 1.25m

g = 9.81m/s^2

PE = mgh

For adult:

mgh = (82.5kg)(9.81m/s^2)(1.25m) = 1011.65 J

For child:

mgh = (14.7kg)(9.81m/s^2)(1.25m) = 180.25 J

Difference in PE: 1011.65 J - 180.25 J = 831.4 J
