Some of the early planetesimals that formed the solar system still survive today. Where would you find such planetesimals
madam [21]

Some of the early planetesimals that formed the solar system still survive in the asteroid and Kuiper belts.

Asteroids are the rocky leftover planetesimals of the internal solar device. Planetesimals shape in protoplanetary disks, many develop into big planets, whilst others do no longer get that possibility. in the solar gadget, remnant planetesimals and minor planets inhabit the asteroid belt, Kuiper belt, Oort cloud, and different solid niches.

After the planets had been shaped, their gravity hurled most of the last planetesimals into the solar or into remote orbits around it. Phobos and Deimos are believed to be planetesimals that were captured through Mars gravity and became satellites. many of Jupiter's moons are believed to be planetesimals as well. Planetesimals are very precious to scientists because they are able to offer information approximately the introduction of our solar gadget

A planetesimal is small our bodies from which a planet originated in the early stages of formation of the solar system. Protoplanets are while planetesimals join together thru collisions and via the force of gravity to form larger our bodies

Zone between each team's blue line and goal line in ice hocky​
Aleksandr [31]

Answer:Each goal line is 11 feet (3.4 m) from the end boards. NHL blue lines are 75 feet (22.9 m) from the end boards and 50 feet (15.2 m) apart.

Explanation:When the other team is on the attack, the defensive zone is the area between your goal line and your blue line. The central ice area between the two blue lines (neither the defending nor the attacking zone). When the your team is on the attack, the offensive zone is the area between blue line and your opponents goal.

The question ask:
abruzzese [7]

Answer:

\theta=28.07^{\circ}

Explanation:

Speed of van, v = 28 m/s

Radius of unbanked curve, r = 150 m

Let \theta is the angle with the vertical. In case of banking of road,

T\ cos\theta=mg.............(1)

And

T\ sin\theta=\dfrac{mv^2}{r}..........(2)

From equation (1) and (2) :

tan\theta=\dfrac{v^2}{rg}

tan\theta=\dfrac{(28)^2}{150\times 9.8}

\theta=28.07^{\circ}

So, the string makes an angle of 28.07 degrees with the vertical. Hence, this is the required solution.
