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.

Hi Daralava,
How does the troposphere differ from the stratosphere?
There are 2 major difference between the troposphere and the stratosphere, which is that the stratosphere is higher located than the troposphere, also the stratosphere is also warmer becase it receives more solar radiation the the troposphere.
The three (3) security goals that would align and prioritize security efforts to the business goals of an organization are:
1. Confidentiality
2. Integrity
3. Availability
A security goal can be defined as both the short-term and long-term strategic objectives that detects and protects the assets of a business organization from theft or misappropriation by any internal or external party.
This ultimately implies that, it is very important that security goals of a business organization are aligned with its business goals.
Generally, there are three (3) main security goals for all business organizations and these include:
- <u>Confidentiality:</u> the confidentiality of all data and assets should be well protected.
- <u>Integrity:</u> the integrity of all data and assets should be preserved.
- <u>Availability:</u> all data and assets should be provided for authorized use only.

Answer:
A) Cm = 2.232 s/mm²
B) Time taken to solidify = 74.3 seconds
Explanation:
(A) Since a side is 50mm and all sides of a cube are equal, thus, Volume of the cube is;V = 50 x 50 x 50 = 125,000 mm³
There are 6 faces of the cube, thus Surface Area A = 6 x (50 x 50) = 15,000 mm²
So, Volume/Area = (V/A) = 125,000/15,000 = 8.333 mm
Cm is given by the formula; Cm =[Tts] /(V/A)² where Tts is time taken to solidify and it's 155 seconds in the question. Thus;
Cm = 155/(8.333)²= 2.232 s/mm²
(B) For;Cylindrical casting with D = 30 mm and L = 50 mm.;
Volume of cylinder is;
V = (πD²L) /4
So,V = (π x 30² x 50)/4 = 35,343mm³
Surface area of cylinder is;
A = (2πD²)/4 + (πDL)
Thus, A = ((π x 30²)/2) + (π x 30 x 50) = 6126 mm²
Volume/Area is;
V/A = 35,343/6126 = 5.77 mm
Same alloy and mold type was hsed as in a above, thus, Cm is still 2.232 s/mm²
Since Cm =[Tts] /(V/A)²
Making Tts the subject, we have;
Tts =Cm x (V/A)²
Tts = 2.232 x (5.77)² = 74.3 seconds
Answer:
True
Explanation:
well I agree somehow though
