Athens was known for its love of pottery , the sculptures , and architecture
I hope that's help !
Answer:
The horizontal component of this force is about 36 N.
Explanation:
Given that,
Bruce is is pulling on his lead with a force of 40 N
Angle below horizontal,
We need to find the horizontal component of this force. The horizontal component of any vector is given by :
or
So, the horizontal component of this force is about 36 N. Hence, this is the required solution.
B.mantle convection
C.subduction
D.trench formation
The correct option is (B)mantle convection
Tectonic plates at the earth's surface move because of the intense heat in the Earth's core. this heat causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell and producing a movement called mantle convection which is the slow creeping motion of Earth's solid silicate.
the minimum amount of horizontal force that the man will need to apply so
that the tree will start moving?
A. 240 N
B. 360 N
C. 480 N
D. 120 N
Answer:
120 N
Explanation: First we shoud consider the forces acted on a tree
Friction foce - acting opposite to the moving direction
Weight - Directly acting downwards
Reaction - Directly acting on upwards
For minimum required force should be equal to the friction force
F = μ R
F = 0.5×480
= 120N
