A 4N mass is hung at 85cm mark on a meter rule given that the pivot is praced at 75cm mark . Determine the mass of the meter rule
Two Zuc point changes are located on the x-axy. One is at x= Im and the other is at n=-1m.
(a). Determine the electric field on the y-axis at
y=0.5m
the search coil has 200 turns and a cross sectional area of 3.5 x 10-5 m2. the search coil is placed at x = 0.070 m. show that the magnetic flux linkage through the search coil is about 5x 10-4Wb
A 2kg pulley with a 0.25m radius with a rotational inertia of (1/2)(mr^2) is connected to a 16kg bucket of water. The pulley has an initial clockwise angular velocity of 12rad/s. Calculate the maximum height that the bucket will reach. Calculate the angular acceleration on the bucket.
In a hydroelectric power plant, 100 m 3 /s of water flows from an elevation of 70 m to a
turbine, where electric power is generated. The overall efficiency of the
turbine–generator is 86 percent. Disregarding frictional losses in piping, estimate the
electric power output of this plant.
Sphere A has charge of +10.0 C. It is brought in contact with a neutral sphere B and then separated. Find the final charges on spheres A and B if
a. The spheres have equal radius and
b. If the radius of sphere B is twice the radius of sphere A
Experiment 3
Aim: To be able to understand, visualize and analyze geologic maps.
Apparatus
✓ Geology map ✓ Pencil
✓ Paper
✓ Protractor
✓ ruler
methods
1. Draw the topographical profile A-B using the contour lines
2. Draw a geological cross section along the profile using a vertical scale of 1cm : 100m.
3. Interpret the sub-surface geology by constructing appropriate geological boundaries.
4. Label the fold axis on your cross section
Additional Questions
1. What kind of fold is present? Explain how you could interpret this from the map only.
2. What is the relative age of the dolerite, shale and coal seam?.
3. A chilled margin was observed in the dolerite. Explain what a chilled margin is and how it occurs.
4.write a brief geological history of the area.

initial speed of 15 m/s . Calculate
a. P.E at the maximum height
b. K.E at the instant it will strike the ground
c. P.E after 1 s
d. K.E after 1 s
Find the charge and current at time t in the circuit, at R = 40 ohms, L = IH, C = 16X10^-4 F
E(t) = 100cos(10)t, initial charge and current are both zero.
A spring with mass of 2 kg has natural length of 0.5 m. A force of 25.6 N is required to maintain, it stretched to a length of 0.70 m. If the string is stretching to a length of 0.70 m and then released with initial velocity 0, find the position of mass at anytime t.
