Answer: The second force applied to the doorknob
Explanation:
The formulae for torque is simple the product of the applied force and the perpendicular distance.
The greater the perpendicular force, the greater the torque assuming a constant value of force.
Applying the force at the doorknob gives for a greater distance between the force and the turning point compared to applying the force at the midpoint of the door ( which is at a shorter distance)
If you start at 100% and divide it by 2 it will equal 50% then divide by 2 again and the answer will be 25%. Your answer should be 25%
Answer:
Explanation:
The time taken by the light to travel a given distance is defined as:
Here c is obviously the speed of light. Now we convert the average distance form Venus to Earth to meters:
Finally, we calculate the minutes taken by the light to travel from Venus to Earth:
The greater the MASS of a moving object, the more kinetic energy it has. <3
Answer:
A. Materials with a low index of refraction cause light to refract very little.
