Answer:
Explanation:
a)Magnitude =
84=
x= +50.67 or -50.67 units
b) We are given that the resultant is entirely in the -ve x direction which means that the y-component of the resultant is 0; It means that the y-component of the next vector = -ve of the y component of the initial vector i.e 67.
To make the magnitude 80 units in the negative x direction where the y component is 0, the x component must be -130.67(-50.67 - 80) as the x component is + 50.67units.
Magnitude = = 146.85 units
c) The direction vector = 67/146.85 i - 130.67/146.85 j where i corresponds to the vector in y direction and j corresponds to the vector in x direction. Or this vector is at an angle of 180 - i.e 152.85 degrees from the +ve x-axis.
Answer:
2292W
Explanation:
Use the formula for energy first:
Where E = Energy || D = Distance || M = Mass.
Solve that equation:
E = 5 * 5500 ==> 27500J
To find power, divide energy per time:
27500J / 12s =~ 2292W

Answer:
Patm or the presion at the top is equal to 110977.28[Pa]
Explanation:
First we must define the absolute pressure value, which is equal to the sum of the atmospheric pressure plus the manometrial pressure.
Now we can find the manometric pressure.
Therefore:
