</span><span>Efficiency is the
measure of how efficient a process is. It is used to assess the ability of a
process in avoiding waste energy, materials, money and time in doing a
desirable output. It is calculated as;
Efficiency = useful energy ouput / total energy input</span>
<span>.40 = useful work / 200</span>
<span>useful work = 80 joules</span>
A. Insulator paper is a good insulator of heat
<u>Answer: </u>
Balloon powered car works on the principle of Newtons III law. Escaping air from the balloon, the car accelerates forward. The reaction is the air behind the car, pushing against it, and with the same force car moves forward is the action.
<em>Some scientific questions are:</em>
1. What is the energy stored in the balloon?
Ans: Potential energy (Potential energy is stored in elastic balloon)
2. Which energy is used in balloon-powered car?
Ans: Kinetic energy. (Whenever the balloon escapes the air, potential energy is converted into Kinetic energy)
3. What is the principle involved in balloon powered car?
Ans: Newtons III law.
Answer:
Explanation:
Torque produced = tangential force x radius
= 290 x .33
= 95.7 N.m
angular acceleration = Torque / moment of inertia
.816 = 95.7 / moment of inertia
moment of inertia = 95.7 / .816
= 117.28 kgm².
Answer:
Galactic Zone Grounds
Located in the employees only area by some dumpsters and a body. Located at the top of the Arcjet Tower. After exiting Nuka-Galaxy, check behind the gate for a star core. After you've turned the power on in Power Play, take the elevator in Starport Nuka to the top floor to find a star core.
