Answer
Can the wave travel between the Sun and Earth.
Explanation:
This would be due to the fact that mechanical waves alone require a medium to travel. Electromagnetic waves that are produced on the sun subsequently travel to Earth through the vacuum of outer space. ... Mechanical waves require a medium in order to transport their energy from one location to another.
Deposition moves that have already been eroded, and builds up sediment.
erosion is just the moving of sediment from one place to another
The box is kept in motion at constant velocity by a force of F=99 N. Constant velocity means there is no acceleration, so the resultant of the forces acting on the box is zero. Apart from the force F pushing the box, there is only another force acting on it in the horizontal direction: the frictional force
which acts in the opposite direction of the motion, so in the opposite direction of F.
Therefore, since the resultant of the two forces must be zero,
so
The frictional force can be rewritten as
where
,
. Re-arranging, we can solve this equation to find
, the coefficient of dynamic friction:
Answer:
Option (b) will be correct answer for accelerating the car
Explanation:
For accelerating the car we have to speed up the car
In option (b) it is given that stepping on the gas pedal to speed up the car so it is correct answer
In option (c) it is given that pressing the pedal to slow down the car it is a case of deceleration so it is a incorrect statement.
In option (d) it is given that speed is constant at curved path so acceleration will be zero because if there is no change in velocity then acceleration will be zero
Answer:
With his work, Maxwell unified electricity, magnetism and light, which are known as «Maxwell's synthesis.» Such a synthesis set a milestone in the history of the unification of forces that were so powerful that many nineteenth-century physicists thought the physical laws were already sufficiently comprehended.
