Answer: 1. 0.25 m/s squared
2. A = 0.4 m/s^2
3.=20kg. I did this before.
Explanation:
Answer:
-223.64684 J
Explanation:
F = Force that is applied to the crate = 68 N
s = Displacement of the crate = 3.5 m
= Angle between the force and displacement vector = (180-20)
Work done is given by
The work that Paige does on the crate is -223.64684 J
1. Air resistance (therefore, the air density, shape (aerodynamic or not), and surface area affected
2. The gravitational acceleration constant (g = 9.8 m/s^2 on Earth)
<span>Moon tides or lunar tides are caused
by the pull of gravity between the moon and earth. The moon will exert a
gravitational pull on earth and the earth also pulls the moon towards itself.
One of the results is that the moon is near the earth and the other one, the
oceans tide. Even though the earth can hold any object within ts proximity, the
ocean is partly attracted due to its liquid property. At night, the ocean tends
to be attracted to the moon by creating a bulge and assigning it as ‘high tide’.
This is due to the strong gravitational pull of th moon to the earth. The answer
is letter D.</span>
