Greater than is the answer. Pulling an equal force provides no acceleration and no movement. Pulling less than would still cause the object to move to the right.
C. middle layer, density increases with depth as pressure increases
Explanation:
The mantle is the middle layer of the earth. It's density increases with depth as pressure increases.
- Based on the compositional division of the earth, our blue planet is divided into crust, mantle and the core.
- The crust is the lightest and the outermost layer of the earth.
- The mantle is the middle layer. Its density lies between that of the core and crust.
- The mantle is the largest layer and density increases with depth here.
- The core is a metallic ball. It is the most dense part of the earth.

Answer:
u = 3.35 m/s
Explanation:
given,
mass , m = 0.455 kg
R = 0.675 m
Height of Loop = 1.021 m
the speed required at the top of loop be v
equating the force vertically
v² = 6.622
v = 2.57 m/s
Let the initial speed of ball be u
using conservation of energy
where, 
0.7 u² = 7.85092
u² = 11.2156
u = 3.35 m/s
the initial speed is 3.35 m/s
Gave him good advice to others
Answer:
All the elements of a period have similar chemical properties because they have the same number of valence electrons in their outermost shell. Their atoms have the same number of electrons in the highest occupied energy level
