Answer:
as
- Mass of sun > Mass of earth
Therefore, the sun will exert more gravitational force on earth.
Explanation:
While comparing the gravitational force exerted by two objects, we need to observe which object has a greater mass.
- The object with the greater mass exerts a more gravitational force on the other object.
We know that mass of the sun is about 1.99 x 10³⁰ kg, and the earth's mass is only 6.0 x 10²⁴.
as
- Mass of sun > Mass of earth
Therefore, the sun will exert more gravitational force on earth.

your welcome
Because the strength of the gravitational forces between two objects
depends on the distance between the objects' centers, and when your
elevation changes, so does the distance between your center and the
center of the Earth.
Generally living things become fossils. Plants, animals, etc.
The change in frequency is called the Doppler effect. The speed of the car can be calculated by the formula for the Doppler effect for when the observer is standing still and the source of the sound is moving towards him:
f¹={V/(V-Vs)}*f,
where f¹ is the frequency of the car while moving towards the observer, V=343 m/s is the speed of sound, Vs is the speed of the car and f is the frequency of the car while standing still.
We need to solve the equation for the Vs:
f¹/f=V/(V-Vs)
V-Vs=V/(f/f¹)
-Vs=V/(f/f¹)-V
Vs=-V/(f/f¹)+V= -343/(300/330)+343=-343*0.91+343=-312.1+343=30.9 m/s
So the speed of the moving police car is Vs=30.9 m/s.
