Gravity is an example of friction. If we didn't have gravity, we would be flying all over the place. Also, friction keeps us from sliding on the ground and falling.
Answer
Ceres, Pluto, and Eris are classified as DWARF PLANET.
A) Leftover planetesimals inside the frost line are known as ASTEROIDS.
B) METEORITES are the pieces of Asteroids which are fallen on the earth's surface.
C) COMETS are the objects which are visible with long tails.
D) COMETS are also the leftover planetesimals that are occupied by the jovian planets and are formed in the solar system.
E) Meteor showers are associated with debris from COMETS
Answer:
Time taken to cover the distance 11.45 s.
Explanation:
The given parameters:
Initial Velocity(u)=24 m/s
Acceleration (a)=8
Distance or Displacement(s)=800 m
Displacement or Distance is equal in the above because it travels in a straight line.
We have to apply Second Equation of Motion,
s=ut+
800=24t + 4
200=6t +
+ 6t - 200=0
Solving, the quadratic equation to find out the roots, we get that the possible values of t will be 11.45 s and a negative value.
The negative value will be neglected as time cannot be negative.
Hence, the time taken is 11.45 s.
Answer: F = 0.17N
Explanation: From the Newton second law of motion.
F= m(v-u)/t.
V=180km/hr = 180×1000/3600= 50m/s
U= 160km/hr = 160×1000/3600= 44.44m/s
t= 5secs
F=m(v-u)/t
F= 0.150(50-44.44)/5
F=0.150×5.56/5
F= 0.835/5
F= 0.17N rounded to two decimal places.
