→ The tension on the cable is 890 N.
The free body diagram is drawed below. Applying the second law of newton:
(you have to transpose the T forces to the 'y' axis). After that:
89 x 10 is the Weight Gravitational force (Mass times gravity). Therefore:

Speed of the boat after 18 days:
(c)
Distance traveled in 18 days:
using the equation of motion
The true answer is C.
The boat is attracted to the magnet by the force of magnetism.
Let me explain. If Ashley made the paper boat and place it on the water, gravity will try to pull the boat down, however no magnets are used in this situation.
Now if magnets are used in this situation and the paper clip is attach to the boat, rather than gravity pulling it down, the magnet will be pulling paper clip, causing the boat to move, so instead of gravity, it's magnetism.
Note: Magnets=Magnetism
A microscope is an instrument from which you can see the cells of an object.
It helps you to observe the cells of substance.
Powerful microscopes helps better in observing minute particles or bacterias.
Hope it helps...
Answer: B. Only the mass of the planet
Explanation:
the confusion on the concepts of mass and weight arises from the fact that the acceleration due to gravity is more or less constant in any place on the Earth's surface, thus the weight of an object is directly proportional to its mass. hope it helps <3
