Answer:
No sand doesn't stay sand forever.
Explanation:
- We may have a thought that the sand we see on the beach areas are always the same one for eternal, but it is not true.
- Due to different activities like beach nourishment, sand replenishment etc. the sand in the beach areas are changed and replaced.
- If the sand remained there for long time, it also affects the sand eating organisms and plants.
Out of the choices given, the best choice to explain the direction of the moving force of air is from area o high pressure to areas of low pressure.
Answer:
1) W = 150 J
Explanation:
Work (W) is defined as the product of force F by the distance (d)the body travels due to this force.
W= F*d Formula ( 1)
The work is positive (W+) if the force has the same direction of movement of the object.
The work is negative (W-) if the force has the opposite direction of the movement of the object.
The component of the force that performs work must be parallel to the displacement.
Work done to lift the floor box to its final position
We apply the formula (1)
W= F*d
W = (100 N)*(1.5 m)
W = 150 J
Answer:
Kinematics is the motion of objects without reference of forces that causes the motion in objects.
Explanation:
Answer:
Electric field, E = 300.65 N/C
Explanation:
Given that,
Intensity of a beam of electromagnetic radiation, 
We need to find the maximum value of the electric field. The intensity of electromagnetic wave in terms of electric field is given by :
c is the speed of light
E = 300.65 N/C
So, the maximum value of the electric field is 300.65 N/C. Hence, this is the required solution.
