Answer:
88.1 N
Explanation:
As shown in the free body diagram attached to the question, the only forces acting on the inner block include in the required vertical direction.
- Its Weight.
- Frictional forces as a result of the Two compression forces.
If the block is not to slip off, the weights must match the two frictional forces
Let the compressive forces be F and frictional force be Fr
Fr = μ F
Sum of force acting on the inner block in the y-direction
Fr + Fr - W = 0
μ F + μ F = mg
2 μF = 118
2(0.67) F = 118
F = 118/1.34
F = 88.1 N
Each of the compression forces is 88.1 N
Hope this Helps!!!
I think the correct answers from the choices listed above are options A, E, and F. The conditions on <span>meteorites in space that are similar to those that likely prevailed on Earth early in its history would be </span>no oxygen, presence of inorganic molecules and <span>high levels of ultraviolet radiation. Hope this answers the question.</span>
Answer:
8.33 m/s
Explanation:
v=d/s, velocity = displacement/ time
The solar system shows the planets in their orbits around the sun in this order: Mercury, Venus, Earth with Moon, Mars, Jupiter, Saturn. Fixed stars are around the outside of the orbit of Saturn.
Explanation:
Aristarchus of Samos was an ancient Greek astronomer and mathematician who presented the first known heliocentric model that placed the Sun at the center. So I had to choose the choice that was most similar to that.
Answer:
B. Both of the crates are accelerating at the same rate.
Explanation:
This is a <em>conceptual</em> question. Ignore the values. This is a <em>trick</em> question.
My question to you: both of these crates are falling on Earth, right?
Now chew on this:
What's the value of acceleration due to gravity on Earth?
Hope this helps you! Have a great day!
