I need help with dis hard stuff, you just need to make a thing on Constructing a Device to Regulate the Release of Energy

Explanation:.the device controlled the activation as shown by the water holding room temperature for 15 seconds until activation by crushing the pills. The temperature rose 30° over two minutes, showing a measurable exothermic reaction from the Calcium Chloride dissolving in the water. Pour 5mL water in a quart bag Place Thermometer in the bag to make contact Fill two gelatin 000 capsules with 1 gram of Calcium Chloride Place capsules into the bag Wait 15 seconds to crush the capsules while they are submerged in the water Temperatures - 0 Seconds 75° 15 Seconds - Activation 75° 30 Seconds 85° 60 Seconds 95° 90 Seconds 104° 120 Seconds 105° Test #2 For this trial, the variables of the water Calcium Chloride will be increased by the factor of one.

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
