Answer:
13 seconds
90 seconds
Explanation:
=Velocity of sidewalk = 1.2 m/s
=Velocity of woman = 1.6 m/s
Distance to travel = 36 m
Time = Distance / Speed
Time taken by the woman if she walks in the same direction the sidewalk is moving is 13 seconds
Time taken by the woman if she walks opposite to the direction the sidewalk is moving is 90 seconds
The correct answer is A) Move the objects closer together. Hope this helps.
a temperature difference and the presence of electromagnetic waves
Explanation:
For radiations to occur, there must be presence of temperature difference and electromagnetic waves.
Radiation is a form of heat transfer that does not require a medium. Any hot body emits radiation from its surface.
A hot body is not at thermal equilibrium with its environment.
It has some of its electrons in excited state and by so they emit radiations.
Electromagnetic waves that vibrates transversely emits radiations. This is the mode of heat transfer in place for most electromagnetic waves

Answer:
Workdone = 1476 Nm
Explanation:
Given the following data;
Force = 164 N
Mass = 55kg
Distance = 9 m
To find the work done;
Workdone = force * distance
Workdone = 164 * 9
Workdone = 1476 Nm
Therefore, the work done by the force on the television set is 1476 Nm.
