When describing linear motion, you need only one graph representing each of the three terms, while projectile motion requires a graph of the x and y axes. Graphs of simple harmonic motion are sine curves. Circular motion is different from other forms of motion because the speed of the object is constant.
Answer:
Explanation:
Given
Distance between Pluto and sun is 39.1 times more than the distance between earth and sun
According to Kepler's Law
where k=constant
T=time period
R=Radius of orbit
Suppose is the radius of orbit of earth and sun
so Distance between Pluto and sun is
and is the time period corresponding to and R_2[/tex]
divide 1 and 2
Answer:
4.11 s.
Explanation:
The period T of oscillation of the pendulum is given by the formula:
The maximum oscillation point it can reach is 45 °,
This point is the equivalent of T / 4, which is the moment when it reaches equilibrium.
So for T / 4,
Global warming is the unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. ... Temperatures are certain to go up further. Despite ups and downs from year to year, global average surface temperature is rising.
