Answer:
the four seasons would each be twice as long as they are now
Explanation:
A year is the result of the Earths revolution around the sun i.e., the Earth takes 365 days to complete one revolution around the sun. A day is the result of the Earth's rotation on its axis i.e., it takes 24 hours for Earth to complete one rotation on its axis.
The Earth is titled by about 23.5 degrees, this results in the seasons of Earth. The distance from the sun has nothing to do with the seasons. During the northern hemisphere winter the Earth is actually closer to the sun than in the summer. So, if our year was twice as long then the seasons would be twice as long.
Mechanical energy of the ball will remain conserved
so here we have
so mechanical energy will remain same at all positions
Now when ball comes to position of 1 m height then potential energy is given as
Now since total mechanical energy is conserved so we will say
so we have
its mechanical energy = 3.92 J
its potential energy = 1.96 J
its kinetic energy = 1.96 J
The kinematic formula I would use is v(f)=v(i)+at so plugging in the values you'd get 5.5=14+a*6
So a= -1.42, the answer is negative because the car is slowing down.
The answer is B. The farmers will need to know what will happen as a result, to determine if it is worth releasing the insect.
