3 0

Answer:

40KJ

Explanation:

m=200g

V=20m/s

Ek=?

Ek=(m*V²)/2

Ek=(200*20²)/2

Ek=(200*400)/2

Ek=80 000/2

Ek=40 000 J =40KJ

mariarad [96]

Answer:

3. µs g /7

Explanation:

The largest Force appear when the maximal friction Force is required.

Second Newton law for the small block:

F_friction=u_s*N=u_s*(mg)

F-F_friction=ma

F-u_s*(mg)=ma

Second Newton law for the Big Block:

F_friction=7ma

u_s*(mg)=7ma

a=u_s*g/7

3) venus and earth are nearly the same size and distance from the sun. what are the main differences in the geology of the two p
MissTica

Venus has a surrounding that is approximately one hundred instances thicker than Earth's and has surface temperatures that are extraordinarily hot. Venus no longer has life or water oceans as Earth does.

Venus additionally rotates backward in comparison to Earth and the alternative planets. The geology of Earth is dominated by plate tectonics, Venus has "blob tectonics," wherein the growing of hot material from inside performs a dominant position in sculpting its surface. Venus is also one-of-a-kind from Earth in having miles decrease stage of erosion, because no precipitation and surface wind speeds are very low.

Venus is often called "Earth's dual" because they're similar in size and structure, but Venus has severe floor heat and a dense, poisonous environment. If the sun have been as tall as a typical front door, Earth and Venus could never be about the scale of a nickel.
