Previous rocks melt and collide and to form igneous rocks.
Igneous rocks disintegrate due to weather disruptions and get carried away by water, where they form sedimentary rock strata by lithification.
Igneous and sedimentary change by heat and pressure to form metamorphic rocks.
Metamorphic rocks melt and become igneous rocks.
Answer:
b) 4781 N
Explanation:
Because there is a redius do this question is talking about the acceleration force which= mv^2/r
so a=15^2/80=2.8125 m^2/s
so the force will be = m.a
F =1700×2.8125=4781.25 N
<span>Since the force is applied at an angle from the
horizontal, we will use the horizontal component of this force in calculating
for the displacements.
From derivation, the Fx is:</span>
Fx = F cos φ
Where:
Fx = is the horizontal component of the force
F = total force
φ =
angle in radian = 37 * pi / 180 = 0.645 rad
Calculating: Fx = 30.0 N * cos(0.645)
Fx = 23.97 N = 24 N
Calculating for Work: W = Fx * d
A. W = 24 N * 15 m = 360 N
B. W = 24 N * 16 m = 384 N
C. W = 24 N * 12 m = 288 N
D. W = 24 N * 14 m = 336 N
Explanation:
According to newtons first law of motion " A body is at a state of rest or uniform motion unless acted upon by a force (external)" which will either
1. change the direction
2. change the acceleration
3. change the velocity(moves or stop the body from moving)
4. change the shape or size
180 - (40 * 2) = 100°
So the answer is (D) 100°
Hope this helps! :)
