Answer:
planets move in elliptical orbit.
Explanation:
this is because planets are formed closer to the sun while the comets are formed further.

Answer:
A. 260 mm
B. - 18
C. 175
Explanation:
A
The expression for the lens equation is



v = 259 mm
= 260 mm or 26 cm (to 2 s.f)

Answer:
circuito paralelo
Explanation:
Siempre el circuito en paralelo dara una resistencia menor. Recuerda que las resistencias se suman en el circuito en serie, an cambio en el circuito en paralelo, la corriente se bifurca de manera de circular con mayor intensidad por las ramas que tengan menos resistencia, y tal situacion llevara siempre a producir una menor resistencia equivalente.
Answer:
<em>Answer: D. Only R</em>
Explanation:
<u>The Principle Of Conservation Of Mechanical Energy</u>
In the absence of friction, the total mechanical energy is conserved. That means that
Em=U+K is constant, being U the potential energy and K the kinetic energy.
At the top of the path (point Q), Joshua is at rest but his height is at a maximum. Thus his kinetic energy is zero.
At point P, Joshua is at the minimum level (potential energy zero) and his speed is at a maximum.
At point R, Joshua has some height and some speed which means he has both types of energy.
Answer: D. Only R
