A 2.50 × 105 W motor is used for 26.4 s to pull a boat straight toward shore. How far does the boat move toward shore if a force of 4.20 × 104 N is applied by the motor?

Answers

Answer 1
Answer: The power of the motor is
2.50x10⁵ W
or 
2.50x10⁵ N m/s

The time it takes to pull the boat is
26.4 s

The force applied is
4.20x10⁴ N

The distance traveled by the boat is
2.50x10⁵ N m /s (26.4 s) / (4.20x10⁴ N)
 = 157.14 m
Answer 2

Answers

Explanation:

Inertia is related to only mass, not speed.

Since a jet plane has more mass than a car, it has more inertia.

Nicholas sends 20.0 minutes ironing shirts with his 1800-watt irn . How many joules of energy were usedby the iron

Answers

1 watt = 1 joule/sec
1800 watts = 1800 joules/sec

                 (1800 J/sec) x (20 min) x (60 sec/min)

             =  (1800 x 20 x 60) joules  =  2,160,000 joules .

What happens to an earthquake's S-waves when they strike the core?A) They bounce off
B) They are absorbed
C) The change into P-waves
D) They change into L-waves

Answers

Answer:

B) They are absorbed

Explanation:

B is correct because S waves can only travel through solid materials.  When they hit liquid materials they are absorbed in and undetectable.

Answer:

B) They are absorbed

Explanation:

When they hit the liquid core, S-waves are no longer able to be detected. While P-waves bounce off the liquid core, S-waves are absorbed at the core.
