Which of the following is not a response?only one

Aa tree turning its leaves towards the sun
Ba mushroom appearing wet in the rain
Ca protozoa contracting when touched
Dyour stomach rumbling when you smell food

B. A mushroom appearing wet in the rain.

Explanation:

Responses are like a cause and effect sequence.

A. A tree will turn its leaves to the sun because it needs the sun to produce energy.

C. Protozoa will contract when touched becasuse it is a very sensitive organisim

D. You stumach will start to rumble when you smell something becasue that is your brain telling you, you need to eat something

The correct answer will be B.

a mushroom will only appear wet when it rains so no.

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
