A1200-kilogram space vehicle travels at 4.8 meters per second along the level surface of mars. if the magnitude of the gravitational field strength on the surface of mars is 3.7 newtons per kilogram, the magnitude of the normal force acting on the vehicle is

The correct answer to the question is : 4,400 N.

EXPLANATION:

The mass of the space vehicle m = 1200 Kg.

The speed of the space vehicle v = 4.8 m/s.

The gravitational field strength E = 3.7 N/Kg.

We are asked to calculate the normal force on the space vehicle.

The gravitational force that acts on the space vehicle is calculated as -

                                Force F = E × m

                                              = 3.7 N/ Kg × 1200 Kg.

                                               = 4.440 N.

The normal reaction on the space craft is equal to the force of gravity on Mars.

Hence, the normal reaction on the space vehicle is 4,440 N.

the answer is b ) square root of 5

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
