Answer:
while(x>=0)
{
<em>loop execution that manipulates x</em>
}
Explanation:
A while loop keep iterating as long as the condition inside is true. The necessary element to remember is to make your the condition variable is altered from within the loop. Otherwise, the loop will become an infinite loop.
The condition state that as long as the variable x is greater than or equal to 0, the loop will continue. If x becomes negative, the loop will terminate.
Answer:
a. There is a force on Jupiter toward the center of the orbit.
d. Jupiter is accelerating toward the center of the orbit.
Explanation:
Let us look at each of the choices one by one:
a. There is a force on Jupiter toward the center of the orbit.
True. The sun being at the center of Jupiter's orbit, pulls the planet towards it (providing the centripetal force), therefore, there exists a force on Jupiter toward the center of the orbit.
b. There is a force on Jupiter pulling it out from the center of the orbit.
Nope. The centripetal force due to gravity acts towards the center of the orbit.
c. There is a force on Jupiter in the direction of its motion.
Nope. There exists only the centripetal force acting towards the center of the orbit,
d. Jupiter is accelerating toward the center of the orbit.
Yes. Because of the centripetal force gravity provides, Jupiter is accelerating towards the center of the orbit, but it does not fall in because it has velocity perpendicular to the direction of its acceleration.

1.Energy efficiency saves you money.
2.Energy efficiency improves the economy.
3.Energy efficiency is good for the environment.
4.Energy efficiency improves national security.
5.Energy efficiency enhances quality of life.
Explanation:
Using,
S = vi*t + 1/2*a*tr^2
vi = initial velocity = 0 m/s
S = 1/2 * 9.8 * tr^2
= 4.9tr^2.
S = vf * (ta - tr)
4.9tr^2 = 330 * (9.3 - tr)
4.9tr^2 - 3069 + 300 * tr)
Using general quadratic equation,
tr = 8.93 s.
S = 4.9 * (8.93)
= 390.75 m.
B.
Therefore,
S = 4.9 * (9.3)^2
= 423.8 m.
