R because A-B has 7R but C-d only has 6r so you need to add another r
Answer:
4.53 second, 195 ft/s
Explanation:
u = 50 ft/s
h = 555 ft
g = 32 ft/s^2
Let the time taken by the ball to reach the ground is t and the velocity of the ball as it hits the ground is v.
Use third equation of motion
v = 195 ft /s
Thus, the ball strikes the ground with velocity 195 ft/s.
Use first equation of motion
v = u + at
195 = 50 + 32 t
32 t = 145
t = 4.53 second
Thus, the ball reach the ground in 4.53 second.
A big difference between Mathilde and Eros is that Mathilde represents a group of separate rocks whereas Eros is a solid rock.
<h3>What is an asteroid?</h3>
An asteroid is a celestial body composed of different types of rocky materials (generally clay but also silicate) and also metals (especially Fe).
An asteroid may have different sizes and some of them can be huge as dwarf planets that travel across the universe.
In conclusion, a big difference between Mathilde and Eros is that Mathilde represents a group of rocks whereas Eros is a solid rock.

Answer:
F = 195 N
Explanation:
F = GMm/d²
F = 6.67e-11(5.97e24)(24) / (7.00e6)²
F = 195 N
Answer:
The correct answer is
1. KE Increases, PE Increases, ME Increases
Explanation:
Here, it is essential to define the following concepts.
Kinetic energy is the energy due to motion of an object. The definition of kinetic energy is the energy to accelerate a body from rest to a given velocity. The body retains the kinetic energy as it maintains the attained velocity
KE= 1/2mv^2
From the above definition KE is increasing
Potential energy is the energy stored within a body due to its location in a position or location of higher potential
As an object moves up to higher altitude in a direction opposite to the earth's attractive force, its gravitational potential increases
PE=mgh
From the above definition PE is increasing
Mechanical energy is the sum of potential and kinetic energies that can be used to do work. It is the sum of the potential and kinetic energies stored in the body
ME = PE+KE
Since both PE and KE are increasing then ME is also increasing
