I personally would write it in a Ballad format.
Ballad poems tell a story.
Narrative poems tells a story often making the voices of the/a narrator or character.
Haiku poems rarely rhyme.
Sonnet poems are rhythmic.
F=ma
W=F*distance
375J=(45kg)(a)(5m)
a=375/(45*5)
a=1.67m/s^2
F=ma = 45kg * 1.67m/s^2=75N
Or go straight there like this:
W=F*distance
375J=F(5m)
F=375J/5m
F=75N
Hope this helps. Thanks
A. A long thin wire because it is thin and long is give the most resistance. That is why people who walk on a wire across buildings have long thin wires.
Answer:
Total time taken by boat to cover all the displacement = 452.3254 sec
Explanation:
We have given speed of boat = 4.72 m/sec
Speed of current flowing = 3.86 m./sec
In downstream relative speed of boat = speed of boat + speed of current flowing = 4.72+3.86 = 8.58 m/sec
Distance traveled downstream = 297 m
So time taken by boat to travel 297 m downstream
In upstream relative speed of speed = speed of boat - speed of current flowing = 4.72 -3.86 = 0.86 m/sec
Distance traveled in upstream = 389 m
So time taken to travel 289 m upstream
So total time
Answer:
Work done in all the three cases will be the same.
Explanation:
1) The free falling body has only one force acting on it, the gravitational force. The work done on the body = mgH (Gravitational potential energy)
2) There are two forces acting on the body going down on a frictionless inclined plane - gravity and the normal force. The gravitational potential energy will be the same. The work done due to the normal force is zero, since the direction of the force is perpendicular to the displacement. Hence, total work done on the body = mgH
3) In the case of the body swinging on the end of a string, the change in gravitational potential enrgy will once again be the same since difference in height is H. The additional force on the body is the tension due to the string. But the work done due to this force is <em>zero, </em>since the displacement of the body is perpendicular to the tension. Therefore, the total work done on the body is once again mgH.
