A CREEP METER employs a weight and a wire to detect horizontal movement.

Explanation:

A creep meter is an apparatus utilized to measure ground above an existing fault line has gradually shifted in a horizontal orientation. A creep meter operates by utilizing a wire extended across a fault line. As the ground shifts in a horizontal orientation, the creep meter measures the difference.

A ray of light strikes the midpoint of one face of an equiangular crown glass prism (n=1.52) at an angle of incidence of 30.0.

NikAS [45]

Answer:

Angle of reflection at plane surface of prism = 30°

Explanation:

Angle of reflection = angle of incidence at any surface plane or curved .

Here angle of incidence at plane surface of prism = 30°

Angle of reflection at plane surface of prism = 30°

If i be the angle of incidence and r be angle of refraction

sin i / sin r = refractive index

= 1.52

sin r = sin i / 1.52

= sin 30 / 1.52

= .5 / 1.52

= .3289

r = 19.2 °

HACTEHA [7]

Answer:

C. Sturdy stems

Explanation:

Sturdy stems is the adaptation that enables water hyacinth to get nutrients directly from the water because there is no roots are present for the absorption of nutrients from water. The hollow bulbous stem below each leaf of water hyacinth allows the plant to get nutrients from the water. This hollow bulbous stem allow the plants to float on the water surface, keeping the leaves and flowers above the water so they don't rot.

PLEASE HELP. GRAVITY QUESTION, WRITTEN RESPONSE.

Rina8888 [55]

1) Forces acting on your body: force of gravity and normal reaction

2) Due to Newton's second law, N = mg

Explanation:

When you sit on the computer, there are only two forces acting on you:

The force of gravity, acting downward, of magnitude $W=mg$ , where m is your mass and $g=9.8 m/s^2$ is the acceleration due to gravity, downward
The normal reaction exerted by the chair on you, $N$ , acting upward

Your body is in equilibrium (it doesn't move), this means that the two forces balance each other, therefore:

$N-mg=0\\N=mg$

We can now apply Newton's second law of motion to this situation; this law states that the net force acting on a body is equal to the product between its mass and its acceleration. Mathematically,

$\sum F = ma$
