At room temperature, good conductors of heat usually feel cool to the touch. this is because they conduct heat so quickly that when
a finger touches them, the heat from the person's lingeris immediately conducted away.
from this information, which of these materials is probably the best conductor of heat?
a.
plastic
b. wood
c. copper
d.
cotton

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

it was given as a lesson and guide for prayer.
