Answer:
The resultant of the vector is 6.63 km
Explanation:
Given;
vector A = 2.3 km 45°
vector B = 4.8 km 90°
The vectors in the x - direction is given by;
Aₓ = 2.3 km Cos 45° = 1.6263 km
Bₓ = 4.8 km Cos 90° = 0
The sum of the vectors in x -direction is given by;
∑X = 1.6263 km + 0 = 1.6263 km
The vectors in the y - direction is given by;
Ay = 2.3 km Sin 45 = 1.6263 km
By = 4.8 km Sin 90° = 4.8 km
The sum of the vectors in y -direction is given by;
∑Y = 1.6263 km + 4.8 km = 6.4263 km
The resultant vector is given by;
R = √(X² + Y²)
R = √[(1.6263)² + (6.4263)²]
R = 6.63 km
Therefore, the resultant of the vector is 6.63 km
Intially, we have:
Pressure P1 = 400KPa
Temperature T1= 110Kelvin
When,
Temperature T2= 235 Kelvin
Pressure P2= ?
We have gas equation:
PV= nRT
P/T= nR/V
Considering nR/T as constant, we have:
P1/T1 = P2/T2
400/110= P2/235
P2= 854.5 KPa
So the new temperature will be 854.5 KPa

Answer:
Answer
Explanation:
The very first generation of star systems in the universe probably consisted only of hydrogen and helium. This means that,
There were no comets or asteroids in these first-generation star systems. As the comets and asteroids were the only soruce of elements other than Hydrogen and Heliums ( As starts mainly consists of helium and hydrogen).
