Answer: Decreasing the distance of the space shuttle from Earth .
Explanation:
According to expression of gravitational force:
G = gravitational constant
= masses of two objects
r = Distance between the two objects.
F = Gravitational force
From the above expression we can say that gravitational force is inversely proportional to squared of the distance between the two masses.
So, in order to increase the gravitational force on space shuttle distance between the space space shuttle must be decreased.
Hence, the correct answer 'decreasing the distance of the space shuttle from Earth '.
Option D, a semi truck parked in a parking lot
Reason: Inertia is the state of a body which needs a force to come into the act of motion.
The more massive the object is the more is its inertia.
Answer: chloroplast
Explanation:
The chloroplast are organelles that conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight
Answer:
Explanation:
Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.
Answer:
B. Friction with air also affects the fall of the object.
Explanation:
The limitation of this experimental design is that friction with air also affects the fall of the object.
- Therefore, it is difficult to measure effect of gravity on falling objects.
- Air resistance cause friction in the movement of an object falling.
- Frictional force resists the motion of an object subject to free fall.
Therefore, the experiment will be biased due to the influence of the frictional force.
