that have a constant velocity.
B. The speed of light in a vacuum is the same for all frames of
reference.
C. The speed of light in a vacuum is the same for stationary frames
of reference.
O D. The speed of light in a vacuum is faster for accelerating frames of
reference

no

Explanation:

no

no

Explanation:

no

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

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
