. Using the figure of the gel below, draw in the DNA bands in the left lane that would appear from the DNA of the person described in the question above. The right lane contains a molecular weight standard. the questions are When circular DNA is sequenced, the nucleotide base pairs are numbered starting from an fixed position on the...
2. A speed skater completes 5 laps around a 500 m track. What is the linear displacement of the skater in meters?
A 1 kg block slides down an inclined plane which makes an angle of 30degree to the horizontal. Starting from rest, it is found to have a speed of 3 m/s after it has moved through a distance of 1.6 m. Find the amount of mechanical energy dissipated due to friction as the block slides down the plane, and hence...

A 0.40-kg mass is attached to a spring with a force constant of k = 207 N/m, and the mass–spring system is set into oscillation with an amplitude of A = 2.0 cm. Determine the following. (a) mechanical energy of the system _____ J (b) maximum speed of the oscillating mass _____ m/s (c) magnitude of the maximum acceleration of...
For a short time the bucket of the backhoe traces the path of the cardioid r = 25(1-cos) ft. The boom is rotating with an angular velocity of 8 = 2.3 rad/s and an angular acceleration of 8 = 0.22 rad/s at the instant shown. (Figure 1) Part A Determine the magnitude of the velocity of the bucket when 0...
Zero Launch Angle - Car Drives Off a Cliff A car drives straight off the edge of a cliff that is h =40 m high. The police at the scene of the accident note that the point of impact is d =86 m from the base of the cliff. Here the initial speed v0 is unknown. Ignore air resistance. The...
Assume g = 10 m/s2 A 4.0-kg block is released from rest at point A. The track is frictionless except for the rough portion between points B and C. The block travels down the track, hits a spring of force constant 2000 N/m, and compresses the spring 0.20 m from its equilibrium position before coming to rest momentarily. What is...
