Answer:
The total power radiated by the sun is 3.71×10^26W
Explanation:
The Earth is spherical in shape
Therefore, Area = 4πr^2 = 4×3.143×(1.489×10^11)^2 = 2.79×10^23m^2
Power radiated by the Sun = solar radiation on Earth × Area = 1330W/m^2 × 2.79×10^23m^2 = 3.71×10^26W
Answer:
The angular speed of rolling ball is 3.23 rad/sec.
Explanation:
Given that,
Radius = 1.95 cm
Speed = 6.30 cm/s
Suppose, we need to find the angular speed of rolling ball
We need to calculate the angular velocity
Using formula of angular velocity
Where, r = radius
= angular velocity
Put the value into the formula
Hence, The angular speed of rolling ball is 3.23 rad/sec.
Answer:
There are actually three, Kepler's laws that is, of planetary motion: 1) every planet's orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet's orbital period is proportional to the cube of the semi-major axis of its
Answer:
1 million dollars once
Explanation:
Well, both would be nice. In total, you will get more from the million dollars because it takes over 2,739 years to get 1 million dollars worth of pennies.(if you get 1 a day that is)
