Answer:
Explanation:
There are various examples around us that states " internal hold back property " and is different from frictional force or the force of Earth's gravity.
The plaster which is the mixture of cement and water has an adhesive nature and molecules inside them has a internal hold back property. They stick to the walls and ceiling and do not fall.
Though gravity is applied on it still its molecules tends to hold the ceiling firmly and do not fall upon.
Answer: Option <em>a.</em>
Explanation:
Kepler's 2nd law of planetary motion states:
<em>A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time.</em>
It tells us that it doesn't matter how far Earth is from the Sun, at equal times, the area swept out by Earth's orbit it's always the same independently from the position in the orbit.
The formula for finding force is F=W/d so then you plug in the numbers:
F=600/4.8
F=125N
