The correct answer to the question is : C) Planets orbit in elliptical patterns; a planet's orbit covers equal areas in equal amounts of time; planets' orbits are shorter or longer depending on their distance from the Sun.
EXPLANATION:
Before coming into any conclusion, first we have to understand three laws of Kepler on planetary motion.
First law: Every planets moves around the sun in elliptical orbits with the sun situated at one of their foci.
Second law: Planets sweep out equal areas in equal interval of time.
Third law: The square of time period of rotation of every planet is directly proportional to the cube of semi major axis.
Hence, from above we see that the option three corresponds to the Kepler's laws partially.
Hence, the correct statement is option three.
Answer:
The acceleration of the ball as it moves down the grassy incline, if constant, is 5.1 m/s²
Explanation:
Initial velocity, u = 0m/s
Acceleration = ?
Vertical distance covered as at t=4.1s, H = 43m
Using the equations of motion,
H = ut + 0.5at²
43 = 0 + 0.5a (4.1)²
a = 43/(0.5×4.1²) = 5.1 m/s²
Hope this Helps!!
You would travel 1200 meters if you run for 10 minutes at 2 meters /second because the total distance traveled by any object is the multiplication of the speed of the object to the time taken to travel that distance.
The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object.
As given in the problem we have to find out the total distance traveled if one runs for 10 minutes at a speed of 2 meters / second.
The running speed = 2 meters / second
The time is taken while running = 10 minutes
=10 ×60
= 600 seconds
The distance traveled by you = 2 meters / second × 600 seconds
=1200 meters
Thus, the total distance traveled by you would be 1200 meters
