A child pulls on a rope attached to a sled with a force of 60 N. The
rope makes an angle of 40° to the ground. (a) Compute the
effective value of the pull tending to move the sled along the
ground. (b) Compute the force tending to lift the sled vertically.
As we know that maximum recombinant frequency possible is 50% & in case of linked genes it is less than 50. But in Mendel's experiment in F2 (dihybrid) the recombinant frequency was 37.5% even though the genes were unlinked( on different chromosomes). Why it comes 37.5% and not 50%?
1. Perform the task in each of the following statements:
a) Write the function header for function zero that takes a long integer built-in array parameter bigIntegers and does not return a value.
b) Write the function prototype for the function in part (a).
c) Write the function header for function add1AndSum that takes an integer built-in array parameter oneTooSmall and returns an integer.
d) Write the function prototype for the function described in part (c).
Determine the magnitude of the Poynting vector and the energy per unit time delivered to a wire of length L and cross-section A when electric current I flows in it.
In a cyclotron, the diameter of the pole faces is 100 cm and the magnetic field between the pole faces is 0.50 T. The cyclotron is used for accelerating protons. Calculate the kinetic energy of proton in eV and speed of the proton as it emerges from the cyclotron. Also determine the cyclotron frequency.
A fuse is made of material that melts when the current density reaches 400 A cm2 . What is the diameter of the fuse wire needed to limit the current to 0.40 A?
