Answer:
Number of electrons, 
Explanation:
Given that,
Charge on the fur, 
A piece of amber is charged by rubbing with a piece of fur. We need to find the electrons were added to the amber. It can be calculated using the quantization of charge as
q = n × e
Where
n is the number of electrons
e is the charge on electron
So, number of electrons are added to the amber. Therefore, this is the required solution.
Yes, Kinetic Energy is a scalar quantity because the direction is not needed. A scalar quantity is one dimensional measurement.
Explanation:
- Kinetic Energy is a scalar quantity that means it has only a magnitude and no direction.
- Energy has a size but no direction; two objects can have the same kinetic energy but they travel in opposite directions.
- The formula of Kinetic Energy is
- K.E =
- Mass is a scalar quantity and velocity is a vector quantity.
- squaring velocity will make vector to scalar quantity.
The solar system is bounded together by gravity, and is made up of the Sun eight planets and dwarf planets
The correct options are;
- The Sun ⇒ generates energy deep in its core through the fusion of hydrogen and into helium
- Earth ⇒ has a single moon that is surprisingly large compared to its planet
- Saturn ⇒ is orbited by at least two geologically active moons: Titan and Enceladus
- Neptune ⇒ has a large moon, Triton, that almost certainly once orbited the Sun independently
- Venus ⇒ has a surface hot enough to melt led as a result of extremely strong greenhouse effect
- Uranus ⇒ has an axis tilt that gives it very extreme seasons
- Pluto ⇒ was studied up close in 2015 by the New Horizons spacecraft.
- Mars ⇒has no surface liquid water today, but shows clear evidence of such water in the distant past
- Jupiter ⇒ has a famous storm known as the Great Red Spot
- Eris ⇒ is similar in size to Pluto and also considered a dwarf planet
- Mercury ⇒ has a greater difference in temperature between its day and night sides than any other world
Reasons:
The Sun generates energy by nuclear fusion in its cores
The size of the Moon more than a quarter of the Earth's size
Saturn moon Titan shows signs of volcanic activity
The moon Triton rotates in the opposite direction to the rotation of Neptune
Venus is the second closest planet to the Sun with a thick CO₂ atmosphere, resulting in a greenhouse effect that makes the planet 510°C hotter
Uranus has seasons that last for approximately 20 years
The New Horizons spacecraft took 9.5 years to reach Pluto after the mission was launched in 2006
Mars liquid water disappeared billions of years ago
The Great Red Spot storm has lasted for over 300 year
Eris, one of the largest dwarf planets and is further from the Sun than Pluto
The difference in temperature between the day and night sides of Mercury is 427°C - (-180°C) ≈ 607°C

Answer:
when you are paddling the push carry on when you paddle the hard put on the push.
For every action there is an opposite and equal reaction. if you think about this u can figure out that force is equal to resistance
