The time for the collision is 3.6S.

<h3>What is collision?</h3>

The collision is an encounter between particles resulting in exchange or transformation of energy.

According to the question,

Force,

F = 5 N

Mass,

m = 3 kg

Velocity,

v₁ = 9 m/s and v₂ = 3 m/s

As we know,

F=m*(v/t)

so,

5=3*(9-3/t)

T=3*6/5

T=18/5

hence, the time for the collision is

T= 3.6S.

What are two reasons why the terrestrial planets formed closer to the Sun after the supernova event that initiated the formation
RideAnS [48]

The correct answers are:

- They are made of denser objects, which can condense at relatively high temperatures;

- They are made of heavier elements, which have a stronger gravitational attraction to the Sun;

All the planets in the Solar system formed from the solar nebula. The conditions though were different for the formation of the planets. The gas giants were not able to form closer to the Sun because of the high temperatures, and those temperatures were not allowing the lighter mater to condensate. On the other hand, those same high temperatures enabled the heavier, denser materials to be able to condensate, thus giving rise to the terrestrial planets.

A bag contains only blue and red marbles.Asman takes 1 marbles at random out of a bag. Probability that she takes a red marble o
Amiraneli [1.4K]
At first situation, ratio = x/y = 1/5
5x = y  -------Equation (i)
Now, after adding 5 more red, it is = x + 5 / y+5 = 1/3
y+5 = 3(x + 5)
y + 5 = 3x + 15
y - 3x = 15 - 5

Substitute the value of y from equation (1), 
5x - 3x = 15 - 5
2x = 10
x = 10/2
x = 5

Originally, There were 5 red marbles in the bag

Hope this helps!

Find the exact volume of this cylinder in terms of π. refer to your staar 8th grade math reference sheet for the appropriate for
lakkis [162]

The exact volume of this cylinder is equal to 225π cubic centimeters.

<h3>How to calculate the volume of a cylinder.</h3>

Mathematically, the volume of a cylinder is given by this formula:

V = \pi r^2h

<u>Where:</u>

  • h is the height.
  • r is the radius.

<u>Given the following data:</u>

Height of cylinder = 9 cm.

Diameter of cylinder = 10 cm.

Radius = \frac{diameter}{2} =\frac{10}{2} =5\;cm

Substituting the given parameters into the formula, we have;

V = \pi \times 5^2 \times 9\\\\V = \pi \times 225

Volume = 225\;cm^3
