Describe at least two ways that electromagnet force and weak nuclear forces are alike and two ways that they are different.
ruslelena [56]

Different: The weak nuclear force is responsible for radioactive decay within an atom of a substance, while the electromagnetic force causes electrostatic force between charged particles.


Different: The weak force has a very small range of effectiveness (where the force can be felt) while the electromagnetic force has an infinite range.


Same: Both forces act within an nucleus, or on a nuclear level.


Same: The weak nuclear force is mediated by charged particles called bosons, and the electrostatic force is only present within charged objects


The last one may be a bit of a stretch but I hope this helped a bit!

A runner can run a 400.0 meter lap in 50.0 seconds.   He finishes at the same spot as he began.  What is his average velocity?

8 meters per second. To find velocity is to divide distance by total time. so 400/50.

Calculate the difference in blood pressure between the feet and top of the head for a person who is 1.70 m tall.
cupoosta [38]

Answer:

P_2 - P_1 = 1.8 * 10^4\ Pa

Explanation:

Given

Height (h) = 1.70m

Required

Determine the difference in the blood pressure from feet to top

This is calculated using Pascal's second law.

The second law is represented as:

P_2 = P_1 + pgd

Subtract P1 from both sides

P_2 - P_1 = pgd

Where

p = blood\ density = 1.06 * 10^3kg/m^3

g = acceleration\ of\ gravity = 9.8N/kg

d =height = 1.70m

P2 - P1 = Blood Pressure Difference

So, the expression becomes:

P_2 - P_1 = 1.06 * 10^3 * 9.8 * 1.70

P_2 - P_1 = 17659.6Pa

P_2 - P_1 = 1.8 * 10^4\ Pa

Hence, the difference in blood pressure is approximately 1.8 * 10^4\ Pa
