Answer:
P = 942.54 W
Explanation:
Given:
Temperature, T = 310 K
mass, m = 70 kg
Now from the stefan's law,
we have the formula
P = σAT⁴
where,
P = radiate energy
σ = Stefan's constant = 5.67 × 10⁻⁸ W/(m² K⁴)
A = Area of the body
Average surface area for a human body = 1.8 m²
T = Temperature
on substituting the values we get,
P = 5.67 × 10⁻⁸ × 1.8 × 310⁴
or
P = 942.54 W
Force = mass * acceleration
Here is an equation for force, used to calculate force.
Look at it this way:-
Joules is used to measure force, while mass is measured by kg. Acceleration is measured by m/s/s (meters per second per second, or meters per second squared.)
joules = m/s/s * kg
Which makes everything fit in just right! :D
Makes no sense get a better question
Now, you always beat him. Your grandfather is likely experiencing a slight decline in perceptual speed.
<u>Explanation:</u>
The speed of perception refers to the capacity to accurately (and completely) compare words letter, digits, objects, images, etc. When testing, these objects can be displayed simultaneously or one after the other. This type of test can be included in the proficiency test.
For example, we have also seen all the puzzles that ask the reader to notice the differences between the two pictures. The time it takes to recognize these differences is a measure of the speed of perception. Likewise, in getting rid of cards at the given situation, grandfather experiences a less decline in his perceptual speed.
