(b) 0.0000000008 pascals [Pa] | |||
(a)

Express the given standard value
Answer to Problem 1ICA
The given standard value
Standard | Scientific | Engineering | With Prefix |
389,589,000 joules [J] |
Explanation of Solution
Given data:
The standard value is
Formula used:
Consider the general Scientific notation as,
Here,
# is single digit to the left of the decimal point which is the most significant nonzero digit,
N is an integer, and
Consider the general Engineering notation as,
Here,
M is an integer multiple of 3, and
# is the number of digits to the left of the decimal point which is one, two, or three as required to yield a power of 10 that is indeed a multiple of 3.
Calculation:
The given standard value in Joules is,
Convert the value into scientific notation using the expression in equation (1) as follows,
Convert the value into engineering notation using expression equation (2) as follows,
Consider the SI prefixes.
Convert the standard value into SI prefixes using the equation (3).
Conclusion:
Hence, the given standard value
Standard | Scientific | Engineering | With Prefix |
389,589,000 joules [J] |
(b)

If the coefficient of static friction between his shoes and the ground is \( \mu_s = 0.4 \) and between the crate and the ground is \( \mu_c = 0.3 \), determine if the man is able to move the crate using the rope-and-pulley system shown. **Diagram Explanation:** The diagram illustrates a scenario where a man is attempting to pull a crate using a rope-and-pulley system. The setup is as follows: - **Crate (C):** Positioned on the ground with a rope attached. - **Rope:** Connects the crate to a pulley system and extends to the man. - **Pulley on Tree:** The rope runs over a pulley mounted on a tree which redirects the rope. - **Angles:** - The rope between the crate and tree forms a \(30^\circ\) angle with the horizontal. - The rope between the tree and the man makes a \(45^\circ\) angle with the horizontal. - **Man (A):** Pulling on the rope with the intention of moving the crate.
