Pls help with these following appreciate it

Question 4 (1 point) Question 5 (1 point) Saved Given the formula below, where Fis force (measured in units of kg.m/s2), r is radius The escape velocity v of a rocket from the surface of a planet of mass M and radius r (measured in units of m), L is length (measured in units of m), v is speed (measured in is given by: units of m/s), dis distance (measured in units of m), what are the units of n? 2GM F = - 2nrLvn U = 1 d If the escape velocity from Planet X is 4 times the escape velocity from Planet Y and Okg . m . s the mass of both planets is the same, the radius of Planet X must be the radius of Planet Y. O kg m 's kg.m 2 times smaller than S 2 times larger than kg's 16 times smaller than m 16 times larger than Question 10 (1 point) Saved Question 8 (1 point) The magnetic force F on a particle moving through a perpendicular magnetic field depends on its charge q, its speed v, and the magnetic flux density B. What happens Approximately how many cars are currently stopped at stoplights in the city of to the force if the speed of the particle is increased by a factor of 4? Hamilton? Note that F has units of kg.m/s2, q has units of A.s, v has units of m/s, and B has O 103 units of kg/(A-52). O 104 It is increased by a factor of 2. O 105 It is increased by a factor of 4. O 106 It is increased by a factor of 16. It is decreased by a factor of 2. It is decreased by a factor of 4. It is decreased by a factor of 16
