Answer:
Explanation:
A ball is thrown vertically upward with a certain Kinetic Energy in the absence of air resistance and while returning it experiences air resistance.
Air resistance causes the ball to lose its kinetic energy as it provides resistance which will convert some of its kinetic energy to heat energy.
So in a way total energy is conserved but not kinetic energy as some portion of it is lost in the form of heat.
Answer:
1) Skid
2)<u> </u>Rocking
3) Oversteer situation
4) Controlled breaking
5) Overdriving headlights
6) Hydroplaning
7) Understeer situation
Explanation:
1) A <u>skid</u> results when a vehicle loses part or all of its grip on the road
2)<u> Rocking</u> is a technique that can be applied when trying to move your vehicle out of deep snow
3) The action of vehicle's rear end sliding out to a side is called an <u>oversteer situation</u>
4) <u>Controlled breaking</u> is a technique of reducing your speed as quick as possible while maintaining control of your vehicle
5) Driving at a speed where the stopping distance of your vehicle is longer than the distance you can see with your headlights is called <u>overdriving headlights</u>
6) <u>Hydroplaning</u> occurs when a tire loses road surface contact and rises on top of water
7) It is an <u>understeer situation</u> when your front tires begin to plow and your vehicle is not responding or not responding as quickly as it should, to a steering point
At resonance, a driven rlcrlc circuit has vcvc = 5. 0 vv , vrvr = 8. 0 vv , and vlvl = 5. 0 vv having a peak voltage across the entire circuit
For any voltage waveform, the peak voltage is the highest point or voltage value. When Pulse Width Modulation (PWM) devices, like variable frequency drives, are added to a power system with a peak voltage that is equal to the square root of two times the RMS voltage, a power quality problem results.
Find the peak voltage, for instance, if the RMS voltage is 85 V. The average voltage and maximum voltage of AC power coming from the wall are both about 110 V. Therefore, the real peak voltage is 120/0.707 = 170 V. The sinusoid's amplitude is divided in half by this. Peak-to-peak voltage (Vp-p), also known as the total amplitude, is 340 V, or twice the peak voltage.
