Answer:
<h2>5,142.86</h2>
Explanation:
The kinetic energy possessed by the block when sliding will be equal to the energy needed to compress the string.
Kinetic energy = 1/2 mv² and energy stored in the spring = 1/2 ke²
m = mass of the block (in kg) = 2.8 kg
v = speed of the block (in m/s) = 2.4 m/s
k = force constant of the spring
e = extension (in metres) = 0.056m
Since KE = energy stored in the spring
1/2 mv² = 1/2 ke²
mv² = ke²
2.8(2.4)² = k(0.056)²
16.128 = 0.003136k
k = 16.128/0.003136
k = 5,142.86
The force constant of the spring is 5,236.36
Answer:
hope this helps u dud have a great rest of ur day(⌐■_■)
Explanation:
1. A toaster transforms electrical energy into thermal energy.
2. A blender transforms electrical energy into mechanical energy.
3. The sun transforms nuclear energy into ultraviolet, infrared, and gamma energy all forms of electromagnetic energy.
4. Our bodies convert chemical energy from food into mechanical and electrical energy to allow us to move.
5. A natural gas stove converts chemical energy from burning into thermal energy used to cook food.
Disregarding that the cities are 120 miles apart in an absolute straight line, because no road is straight,
<span>One can assume that velocity = distance / time </span>
<span>V = 200 miles / 4 Hours </span>
<span>V = 50 Miles / Hour</span>

Answer:
o to increase the frequency of sound waves. It increases the sound waves to a level of frequency that humans cannot hear so you won't be able to hear many things though the wall other then low noises like pounding.
Explanation:
I am in construction class as well as a student teacher for other construction type programs trust me :D
Brainiest would be appreciated
