Answer:
3.25 ft/s
Explanation:
The crate is of =14-lb=m₁
The angle of inclination is = 40°=Ф
The initial velocity = 0.4 ft/s= v₁
Distance the crate will move is= 0.3 ft =d
The load pulling downwards is = 36 lb= m₂
Acceleration of the pulley, a= m₂g - m₁gsinФ / m₁+m₂ where g= 32.17 ft/s^2
a= 36*32.17 - 14*32.17*sin 40° / 14+36
a=17.37 ft/s^2
Apply the formula for final velocity
V₂²=V₁²+2ad
V₂²=0.4²+ 2*17.37*0.3
V₂²=10.582
V₂ =√10.582 = 3.25 ft/s
Answer:
G8 = x0'x2' +x0'x3' +x1x2
Explanation:
The expression can be written different ways, depending on the need to avoid hazards. One of them is ...
__
A truth table and Karnaugh map are shown for the circuit. The terms used in the Boolean expression come from the corners, the upper half of the left- and right-columns, and the right half of the middle two rows. If a static hazard is to be avoided, a term x1x0' could be added representing the right column.
Answer:
0.1788 ,180°,90°,60°
Explanation:
CONVERSION FROM DEGREE TO RADIANS: For converting degree to radian we have to multiply with 
using this concept 10.25°=10.25×=0.1788
CONVERSION FROM RADIAN TO DEGREE: For converting radian to degree we have to multiply with
using this concept π=π×
=180°
= ![\frac{\pi}{2}[/tex×[tex]\frac{180}{\pi}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cpi%7D%7B2%7D%5B%2Ftex%C3%97%5Btex%5D%5Cfrac%7B180%7D%7B%5Cpi%7D)
=90°
= ×
=60°
Answer: Increase in the population of lower organisms.
Explanation: Raccoons are mesopredators found in the middle levels of food webs and have critical impacts on the dynamics of many other species. Thus, they greatly contribute to the functioning of the ecosystem.
They are naturally equipped to checkmate the population size of other organism that are below them (i.e., their preys) in the food web. They are; predators, pathogen carriers (such as rabies), and competitors, as they compete with some specialist in the food web.
Hence, the decrease in the population of raccoons will lead to the increase in the population size of lower organisms they prey on in the food web or chain.
