Answer:

Newton's law of universal gravitation

Explanation:

As we know that all planets revolve around the sun in such a way that sun will provide essential centripetal force to all the planets

this force is given by Newton's universal law of gravitation

U = \frac{Gm_1m_2}{r^2}

Kepler's law of ellipse : it says that all planets revolve around the sun in elliptical path such that the sun lies at one of its focii.

Newton's 2nd law : As per Neton's 2nd law we know that net force on an object is product of mass and its acceleration.

Newton's 3rd law : Every action has equal and opposite reaction.

So here correct answer would be

Newton's law of universal gravitation

Newton's universal law of gravitation says that the force acting upon (and therefore the acceleration of) an object toward Earth should be inversely proportional to the square of its distance from the center of Earth.

Suppose that in a lightning flash the potential difference between a cloud and the ground is 0.96×109 V and the quantity of char
Dvinal [7]

(a) 2.98\cdot 10^{10} J

The change in energy of the transferred charge is given by:

\Delta U = q \Delta V

where

q is the charge transferred

\Delta V is the potential difference between the ground and the clouds

Here we have

q=31 C

\Delta V = 0.96\cdot 10^9 V

So the change in energy is

\Delta U = (31 C)(0.96\cdot 10^9 V)=2.98\cdot 10^{10} J

(b) 7921 m/s

If the energy released is used to accelerate the car from rest, than its final kinetic energy would be

K=\frac{1}{2}mv^2

where

m = 950 kg is the mass of the car

v is the final speed of the car

Here the energy given to the car is

K=2.98\cdot 10^{10} J

Therefore by re-arranging the equation, we find the final speed of the car:

v=\sqrt{\frac{2K}{m}}=\sqrt{\frac{2(2.98\cdot 10^{10})}{950}}=7921 m/s

Why is physics harder than math
jenyasd209 [6]

Answer:

General perception: Physics is harder than Mathematics. Why? Physics might be more challenging because of the theoretical concepts, the mathematical calculations, laboratory experiments and even the need to write lab reports.
