A 52–newton bird feeder is tied to a cord, which is attached to a tree branch. Describe the tension force of the rope.
iris [78.8K]
If you are given a 52 Newton bird feeder tied to a cord, it means that it has a weight of 52 Newton. Since the bird feeder is not moving, we assume it to exert a force downward, that is its weight, and the cord that ties it, the force is upward. This upward force is the tension and is therefore equal to 52N.

the sole of a tennis shoe has a surface area of 0.0290 m^2. if it is worn by a 65.0 kg person, what pressure does the shoe exert
AURORKA [14]

Answer: 21965.517 Pa

Explanation:

Pressure P is the force F exerted by a gas, a liquid or a solid on a surface (or area) A, its unit is Pascal Pa which is equal to N/m^{2} and its formula is:  

P=\frac{F}{A} (1)

In this case we have the surface of a sole of a tennis shoe:

A=0.0290 m^{2} (2)

And the mass m of the person who wears it:

m=65 kg

On the other hand, we know the weight is the force  F the Earth exerts on people and objects due gravity g :

F=m.g=(65 kg)(9.8m/^{2})

F=637N (3)

Substituting (2) and (3) in (1):

P=\frac{637N}{0.0290 m^{2}} (4)

Finally:

P=21965.517 Pa This is the pressure the shoe exert on the ground
