Answer:
Acceleration of the apple towards the earth is: 9.7705 m/s2.
Acceleration produced on earth towards the apple
Explanation:
Given :
We have to convert into the kg ,
so
M= kg
As the gravitational force is existing among the earth and the apple
so
Putting the value of G,M,m and , we get
Consider a1 and a2 be a acceleration due to the gravitational force of earth attraction created on the apples
F= a1 *m
a1=
Acceleration of the apple towards the earth is: 9.7705 m/s2.
again
a2=
So, Acceleration produced on earth towards the apple
Answer:
112J (3 s.f.)
Explanation:
KE= 1/2mv^2
where KE is kinetic energy, m is the mass in kg, and v is the velocity (or speed to take it simply) in m/s.
KE= 1/2(6)(6.1^2)
KE= 111.63
KE= 112J (3s.f.)
Rather than reflecting, most sunlight that reaches the ocean's surface passes directly into the ocean. As the light travels through the ocean, it is absorbed and scattered by molecules and particles. Water absorbs light faster when the wavelength is long and the energy is low.
