<h2>Answer</h2>
Radius is 421 m.
<u>Explanation </u>
A car with a mass of 1,500 kg requires a centripetal force of 640 N to safely follow a circular curve in the road at 13.4 m/s. Therefore, for radius we use formula which is Fc = mv ^ 2 / r,
As mass = m = 1500kg,
Centripetal force = Fc = 640N,
Velocity = v = 13.4 m / s
By putting values, Fc = mv ^ 2 / r,
r = mv ^ 2 / Fc,
=> r = ( 1500kg ) . ( 13.4 m / s) ^ 2 / 640,
=> r = ( 1500kg ) . ( 179.56 ) / 640,
r = 269340 / 640,
=> r = 420.84 m.
Radius is 421 m.
Melting. Water freezes at 0 degrees celsius or 32 degrees fahrenheit and therefore water freezes at that temperature or ice melts back to its liquid state at those temperatures.
Answer:
At the very bottom, whnere the sag is the greatest, Jay’s acceleration is upward.
Explanation:
As Jay lands on the trampoline, Jay’s motion was dowward, the trampoline was opposing his motion and hence, caused him to reach an initial halt position. Afterwards, the trampoline causes Jay to move back into the air and therefore, the change in velocity vector act in upward direction. The acceleration vector is always align towards the change in velocity vector's direction.
Answer:
<em>1.49 x </em>
<em></em>
<em></em>
Explanation:
Kepler's third law states that <em>The square of the orbital period of a planet is directly proportional to the cube of its orbit.</em>
Mathematically, this can be stated as
∝ 
<em>to remove the proportionality sign we introduce a constant</em>
= k
k = 
Where T is the orbital period,
and R is the orbit around the sun.
For mars,
T = 687 days
R = 2.279 x
for mars, constant k will be
k = 
= 3.987 x 
For Earth, orbital period T is 365 days, therefore
= 3.987 x x
= 3.34 x 
R =<em> 1.49 x </em><em></em>
