A twenty-acre park was created to give residents a place to hike, bike, and enjoy other recreational activities. Kathy was hired

to design a map that would show residents how they could easily access different areas of the park. Sean was hired to monitor the number of visitors they have per month and analyze the park’s popularity for funding possibilities. Joan was hired to offer assistance and teach residents about the plants and animals they may encounter while at the park.
Which best describes the tasks Kathy, Sean, and Joan perform?

Kathy and Joan perform tasks common to the Engineering and Technology pathway and Sean performs tasks common to the Science and Math pathway.

Make a general statement about what happens to light as it enters a different medium.
Aleksandr-060686 [28]

Answer:

Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. The wavelength decreases as the light enters the medium and the light wave changes direction.

A golf ball (m = 46.0 g) is struck with a force that makes an angle of 44.4° with the horizontal. the ball lands 193 m away on a
LenKa [72]

Using the formula for bodies in projectile motion, we can calculate for the velocity v:

 d = (v^2) * (sin2theta) / g 

Substituting the given values:

193 m = (v^2) * (sin(2*44.4)) / (9.8 m/s^2)

v= 50.5 m/s

 

Calculating for the impulse I,

I = mf * vf – mi * vi

since mf = mi and vi = 0 (the golf ball starts form rest)

I = m * vf

I = 0.046 kg * 50.5 m/s

I = 2.323 kg m/s

 

Calculating for the force of impact:

I = F t

<span>F = (2.323 kg m/s) / (6.92 x 10^-3 s)
</span>

<span>F =335.7 kg m/s^2 = 335.7 N</span>

The force of gravity acts on all apples on an apple tree. Some apples are twice as far from the ground as others. For the same m
EleoNora [17]

Answer:

c) paractically the same weight

Explanation:

The force of gravity acts on all apples on an apple tree. Some apples are twice as far from the ground as others. For the same mass these twice-as-high apples have _________.a) 1/4 weightb) 1/2 weightc) paractically the same weigh

from newton's law of motion

states that

the rate of  change in momentum of  a body is directly proportional to the force applied on the body

f\alpha=mdv/dt

dv/dt=a

f=kma

f=ma, where k is constant and equal to 1

a=g since the body is falling under gravity

acceleration of the apples become acceleration due to gravity

W=mg

since they all have equal mass, then the weight on the body will be practically and obviously  the same
