I do not understand the full question, however if you are wondering which way Simone and the dog will go, they will go right because the force of 34 N from the dog is higher than the force of 16 N from Simone.
Answer:
Planet Y
Rx = 1.587 Ry
Explanation:
Tx = 290 days
Ty = 145 days
Let the semi major axis of planet X is Rx and of plant Y is Ry.
According to the Kepler's third law of planetary motion
Rx = 1.587 Ry
So, planet Y is closest to star.
<u>Answer:</u>
"Where friction or rubbing results in the transfer of electrons between particles, objects can become negatively or positively charged."
<u>Explanation:</u>
The motion resistance of one moving object with respect to another is called as "Friction". It isn't a basic force, like gravity or electromagnetism. Alternatively, scientists believe it is the product of the electromagnetic attraction in two touching surfaces between charged particles.
The friction have formula:
Friction force (<em>f </em>) = coefficient of friction × normal force (N)
For an instances when one ride a bicycle, an example of rolling friction is the contact between the wheel and the way.
