Answer:
net force is pushing downwards with gravity. this is only if nothing else is acting on the bowl and pushing it
Answer:
Plate separation of each capacitor is 101.132 °A
Explanation:
The formula to calculate the capacitance in empty space as a function of distance (square parallel plates) is:
clearing for distance:
Answer:
I = 3.82 x 10^(−7) A
Explanation:
The formula for magnetic field at the centre of a loop is given as;
B = μI/2R
Where μ is a magnetic constant with a value of 12.57 × 10^(−7) H/m.
I = current
R = Radius = 16/2 = 8cm or 0.08m
B = 3.0×10^(−12) T
So making I the subject of the formula, we obtain ;
I = 2RB/μ
Thus, I = [2 x 0.08 x 3.0×10^(−12)]/12.57 × 10^(−7)
I = 3.82 x 10^(−7) A
Given :
An object 50 cm high is placed 1 m in front of a converging lens whose focal length is 1.5 m.
To Find :
the image height (in cm).
Solution :
By lens formula :
Here, u = - 100 cm
f = 150 cm
Now, magnification is given by :
Therefore, the image height is 3 m or 300 cm.
Answer:
OD) 3.7 kg-m/s
Explanation:
given:
velocity of baseball, v = 25 m/s
angle below horizontal, Θ =
mass of baseball, m = 0.15 kg
Generally, momentum (p) is given by equation:
p = mv
Horizontal component is given by
p = mv cosΘ
= 0.15 kg x 25 m/s x cos
= 3.71 kg- m/s
Hence horizontal component of momentum is OD) 3.7 kg-m/s
