Answer:
the average kinetic energy of water particles - C.
To solve this problem we will apply the concepts related to the Force of gravity given by Newton's second law (which defines the weight of an object) and at the same time we will apply the Hooke relation that talks about the strength of a body in a system with spring.
The extension of the spring due to the weight of the object on Earth is 0.3m, then
The extension of the spring due to the weight of the object on Moon is a value of , then
Recall that gravity on the moon is a sixth of Earth's gravity.
We have that the displacement at the earth was , then
Therefore the displacement of the mass on the spring on Moon is 0.05m
Answer:
590 ohms
Explanation:
Let the resistance of each resistor be 'R'.
Given:
Equivalent resistance of the three resistors in parallel
Plug in the given values and solve for 'R'. This gives,
Now, the equivalent resistance of the three identical resistors in series is the sum of each of the resistors. Therefore,
As the question asks to round off to two significant figures, so we add 1 to the second significant figure because the number next to 8 is 5 which is greater than or equal to 5. So, the number becomes 590.
Hence, the equivalent resistance in series is 590 ohms.
<span>The equation that relates force and torque is Torque = Force*length*sin(angle). Plug in the given values to the equation (convert length to meters first): -13 = Force * 0.35 * sin(30 degrees). Rearrange to solve for Force: Force = -13/(0.35 * 0.5) = -74.3 N (which is the same as a downward force of magnitude 74.3 N.</span>
