Answer:
is called <em>matter</em> :)
Explanation:
I'd have to say that the list of choices doesn't go far enough.
Advances in Astronomy have been occurring for at least the past two millennia (2000 years). Maybe longer.
Answer:
he density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. The symbol most often used for density is ρ
Explanation:
Answer: Crude oil
Explanation: Crude oil is a liquid consisting of hydrocarbons found beneath the Earth's surface. Its refining yields several refined and more useful forms like petrol, diesel, kerosene, etc. All of them are hydrocarbons with different molecular weights. Hydrogen is the odd one out as it is an element and not among the end products of refining.
Solution:
The magnitude of A vector is 84.9 m in the positive y-axis direction.
So the X component of A =0
the Y component of A = 84.9 m
Now the magnitude of B vector is 195 m and it makes an angle of 41° in the direction from the positive x-axis direction.
So the X component of B = B cos 41°
= 195 x cos 41°
= 195 x 0.75 = 146.25 m
the Y component of B = B sin 41°
= 195 x sin 41°
= 195 x 0.65 = 126.75 m
Now it is given that vector C has a magnitude of 126.2 m and it makes a direction towards the positive x-axis.
So the X component of C =126.2 m
the Y component of C = 0
Comparing all these, we get
1. B vector has the largest X component
2. B vector has the largest Y component
