Answer:
The acceleration is -9.8 m/s²
Explanation:
Hi there!!
When you throw a ball upward, there is a downward acceleration that makes the ball return to your hand. This acceleration is produced by gravity.
The average acceleration is calculated as the variation of the speed over time. In this case, we know the time and the initial and final speed. Then:
acceleration = final speed - initial speed/ elapsed time
acceleration = -4.3 m/s - 4.3 m/s / 0.88 s
acceleration = -9.8 m/s²
An increase in average speed of 1 km/h typi- cally results in a 3% higher risk of a crash involving injury, with a 4–5% increase for crashes that result in fatalities. — Speed also contributes to the severity of the impact when a collision does occur. Hope this helps!
Answer:
19 800 lbm of carbon dioxide more.
Explanation:
<u>Taurus</u>
Amount of gasoline used in 5 years = 650 ga/year * 5 years = 3250 ga
amount of carbon dioxide released = 19.8 lbm/ga * 3250 ga = 64 350 lbm
<u>Explorer</u>
Amount of gasoline used in 5 years = 850 ga/year * 5 years = 4250 ga
amount of carbon dioxide released = 19.8 lbm/ga * 4250 ga = 84 150 lbm
Extra amount of CO2 released = 84 150 lbm - 64 350 lbm = 19 800 lbm
Answer:
1.0639 A
Explanation:
We have given rms voltage V = 44 volt
Resistance = 60 ohm
According to ohm's law 
So 
this is the rms current but we have to find the maximum current
So maximum current 
It's <em>chemical energy</em>.
It started out as energy carried in solar radiation. It was absorbed by plants, and they stored it as chemical energy in their stems and leaves. The plants got cut down, washed off, and delivered to the supermarket. Your mom brought them home, camouflaged them so they wouldn't look like veggies, and put them on your plate while you weren't looking. Eventually, some of them got into your body, got digested, and their energy got stored in your cells as glucose and fat. When you needed some energy to do something physical or mental, you grabbed some of that energy that you had stored as chemical energy, and used it to operate your muscles and your brain. You used the glucose (blood sugar) first, and if you ever reached the point where that was running low, you started to use the fat that you have stored around in many places.
