Aworker pulls backwards on a heavy cabinet that slides across the floor at constant speed using a rope as shown below. the rope makes an angle of 37 degrees with the floor and is tied 100 cm above the floor. the tension in the rope is 300 n. the worker gets tired and turns around facing forward to pull forward on the rope with the rope making a 37 degrees angle with the floor and its tension is 300 n. the rope is now connected 65 cm above the floor and the box slides forward. which of the following statements is most correct concerning the worker facing forward?

select one:

a. the box will slide forward at a constant speed, but not necessarily with the same speed when the worker pulled backwards.

b. the box will be easier to slide since more leverage is gained with the force being farther from the floor.

c. the box will be easier to slide since more leverage is gained with the force being closer to the top of the worker's shoulders.

d. this scenario is not possible.

a) cold, dry

explanation:

continental polar masses are cold and dry air masses because the cold air cannot hold much moisture. as they move into warmer air, they can trigger precipitation.

where is the circuit diagram ?

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
