In our Solar System there are nine Planets, It's realy
Answer:
A, the amount of charge stored per volt
Explanation:
Capacitance is defined below:
C = Q/V
Therefore capacitance is charge per volt which gets the unit farad.
Answer:
Q = 40.1 degrees
Explanation:
Given:
- The weight of the timber W = 670 N
- Water surface level from pivot y = 2.1 m
- The specific density of water Y = 9810 N / m^3
- Dimension of timber = (0.15 x 0.15 x 0.0036) m
Find:
- The angle of inclination Q that the timber makes with the horizontal.
Solution:
- Calculate the Flamboyant Force F_b acting upwards at a distance x along the timber, which is unknown:
F_b = Y * V_timber
F_b = 9810*0.15*0.15*x
F_b = 226.7*x N
- Take static equilibrium conditions for the timber, and take moments about the pivot:
(M)_p = 0
W*0.5*3.6*cos(Q) - x/2 * F_b*cos(Q) = 0
- Plug values in:
670*0.5*3.6 - x^2 * 0.5*226.7 = 0
x^2 = 1206 / 113.35
x = 3.26 m
- Now use the value of x and vertical height y to compute the angle of inclination to be:
sin(Q) = y / x
sin(Q) = 2.1 / 3.26
Q = sin^-1 (0.6441718)
Q = 40.1 degrees
Answer:
12kWhr
Explanation:
Energy = Power * Time
Power = 4kW
Time = 3hrs
Substitute into the formula
Energy used up = 4kW * 3hrs
Energy used up = 12kWhr
Answer:
Magnetic field, B = 0.05 T
Explanation:
It is given that,
In magnetic force on a current carrying wire" experiment using the data for force (y-axis, in Newton) versus length in meters, someone obtained a linear curve fit count
y = 0.1 x + 2
Where,
x is in meters
and y is in newtons
Slope of the equation,
Magnetic force is given by,
So, the strength of the magnetic field is 0.05 T. Hence, this is the required solution.
