Answer:
4.78 m/s^2
Explanation:
A)From he FBD
we can write
Tcosθ= mg
Tsinθ= ma
dividing we get tanθ= a/g
a= g tanθ
a= 9.81 tan26°= 4.78 m/s^2
Displacement vectors of 6 km South 2 km North, 7 km South, and 5 km North combine to a total displacement of 6 km South.
Answer: Option A
<u>Explanation:</u>
The displacement vector represents the location change: the distance of separation from the start point to the end point is the displacement vector’ magnitude, and travelled direction denotes the displacement vector’ direction.
In figure, the illustration shows a new vector for the entire journey from beginning to end. In other words, C = A + B. The C vector is called the sum, or resultant vectors. When applying this concept to the given question, we can find the total displacement vector value. It is as follows:
Given:
6 km South 2 km North, 7 km South, and 5 km North
Total displacement, s = 6 km South - 2 km North + 7 km South - 5 km North
North and south lie in an opposite direction. Therefore, when combining all distances negative sign mentioned to denote the direction.
Total displacement, s = 13 km South - 7 km North
Total displacement, s = 6 km South
14 g is the solubility per 100 g water, since it is difficult to read the graph.
<span>Then, in 130 g H20 the solubility would be 14 g KNO3/100 g H2O x 130 g H2O = 18 g KNO3 </span>
<span>The question asks how much crystallizes. </span>
<span>Initial 34.0 g minus 18.0 g still dissolved = 16.0 g crystallizes.</span>
Answer:
Reactance of the capacitor is 0.01 ohms.
Explanation:
It is given that,
Capacitance of the capacitor is 0.5 F
Peak voltage of the battery is 2 V
Angular frequency is 200 rad/s
We need to find the capacitive reactance. The capacitive reactance is due to the capacitor in the circuit. It is given by :
So, the reactance is 0.01 ohms.
