What is the difference between muscular endurance and muscular strength?
a) muscular strength refers to the amount of force in one effort, while muscular endurance refers to performing repeated movements.
b) muscular strength refers to the ability to move joints, while muscular endurance refers to the efficiency of oxygen delivery to cells.
c) muscular endurance refers to the amount of force in one effort, while muscular strength refers to performing repeated movements.
d) muscular endurance refers to the efficiency of oxygen delivery to cells, while muscular strength refers to the ability to move joints.

After the near spacecraft passed mathilde, on several occasions rocket propellant was expelled to adjust the spacecraft's momentum in order to follow a path that would approach the asteroid eros, the final destination for the mission. after getting close to eros, further small adjustments made the momentum just right to give a circular orbit of radius 45 km (45 × 10^3 m) around the asteroid. so much propellant had been used that the final mass of the spacecraft while in circular orbit around eros was only 545 kg. the spacecraft took 1.04 days to make one complete circular orbit around eros. calculate what the mass of eros must be.

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

The charge on an electron is 1.60218 × 10−19 c and its mass is 9.10939 × 10−31 kg. how strong a magnetic field must be experienced by the electron if its path is a circle of radius 5.5 cm? answer in units of t.
