Agroup of particles is traveling in a magnetic field of unknown magnitude and direction. you observe that a proton moving at 1.70 km/s in the +x-direction experiences a force of 2.10×10^−16 n in the +y-direction, and an electron moving at 4.70 km/s in the −z-direction experiences a force of 8.40×10^−16 n in the +y-direction.
1-what is the magnitude of the magnetic field?
2-what is the direction of the magnetic field? (in the xz-plane)(degrees from the z direction)
3-what is the magnitude of the magnetic force on an electron moving in the −y-direction at 3.70 km/s ?
4-what is the direction of this the magnetic force? (in the xz-plane)(degrees from the x direction)

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.

In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendel’s discoveries in genetics. over a century later, darwin’s idea of evolution was modified in order to incorporate mendel’s rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendel’s rules of genetics and darwin’s idea of biological evolution? a.)mendel’s genetics states laws that are now part of the theory of biological evolution.b.)biological evolution states laws that are part of mendel’s theory of genetics.c.)mendel’s genetics replaced darwin’s entire concept of biological evolution.d.)biological evolution is a law that explains why all genetics exist.
