Explanation:
A magnetic field can be created by running electricity through a wire. All magnetic fields are created by moving charged particles. Even the magnet on your fridge is magnetic because it contains electrons that are constantly moving around inside
Answer:
The velocity is
Henrietta is at distance from the under the window
Explanation:
From the question we are told that
The speed of Henrietta is
The height of the window from the ground is
Generally the time taken for the lunch to reach the ground assuming it fell directly under the window is
=>
=>
Generally the time taken for the lunch to reach Henrietta is mathematically represented as
Here is the time duration that elapsed after Henrietta has passed below the window the value is given as 4 s
Now
=>
Generally the distance covered by Henrietta before catching her lunch is
=>
=>
Generally the speed with which Bruce threw her lunch is mathematically represented as
Answer:
(1) Use the data in Table R2 and error propagation rule to compute the travel time ratio (with errors) of the other objects to the hollow cylinder ? ℎ? . Fill in Table R5 below. [6] Table R5 Solid cylinder Billiard ball Racquetball ? ? ℎ? ± ± ± (2) Discuss how the ratio of solid cylinder to hollow cylinder have confirmed or contradicted the theoretical ratio in Eq. (8) in Manual . Compute the % error and make discussions. [4] Answer: (3) From the travel time ratio, please determine (i) whether the billiard ball is solid or hollow, and (ii) whether the racquetball is solid or hollow. Write down your reasons. (The answer can be uncertain if your measurements do not show enough information.) [4]

Please discuss the reason for this relatively largeSEOM and how to improveit. [3] (5) Please discuss TWO possible systematic errors in the measurement. [3] Answer: **Attach your calculation details. Use as many paper sheets as you need. Calculations that demonstrate your understandings may gain you partial credit. **Make sure your work-area and equipment are the same as they were before you leave.
Explanation:
Convert all lengths to metres
A) 100 meters B) 1 meters C) 0.104 meters D) 0.000105 meters E) 0.00000001 meters
Therefore D is the answer
