Slope=∆rise/∆run

A=∆velocity/∆time

A=slope of velocity

Slope=12/6

Slope=2

A=2m/s²

Slope=0

A=0m/s²

Slope=4/4

Slope=1

A=1m/s²

æ:

Slope=-16/4

Slope=-4

A=-4m/s²

An object that has linear kinetic energy must be __________.

stich3 [128]

Answer:

option B

Explanation:

An Object that has linear Kinetic energy so, it must be moving.

Expression of Kinetic energy

$K.E. = \dfrac{1}{2}mv^2$

From the expression above we can clearly see that Kinetic energy is directly proportional to velocity of the object.

If the body has kinetic energy so, it must be moving with certain velocity.

Hence, the correct answer is option B

An exoplanet is in an elliptical orbit around a distant star. At its closest approach, the exoplanet is 0.540 AU from the star a

atroni [7]

Answer:

0.71121 km/s

Explanation:

$v_1$ = Velocity of planet initially = 54 km/s

$r_1$ = Distance from star = 0.54 AU

$v_2$ = Final velocity of planet

$r_2$ = Final distance from star = 41 AU

As the angular momentum of the system is conserved

$mv_1r_1=mv_2r_2\\\Rightarrow v_1r_1=v_2r_2\\\Rightarrow v_2=\frac{v_1r_1}{r_2}\\\Rightarrow v_2=\frac{54\times 0.54}{41}\\\Rightarrow v_2=0.71121\ km/s$

When the exoplanet is at its farthest distance from the star the speed is 0.71121 km/s.
