Physics
1 answer:
cricket20 [7]3 years ago
6 0

Answer:

C. An area with a large river and significant elevation changes

Explanation:

"The best location for a hydroelectric station should be along the path of a river. It should be at least at the river canyon or at the place where the river narrows. This enables the collection of the water or the diversion of the river."

Hope this helps

A spring with a spring constant kk of 100 pounds per foot is loaded with 1-pound weight and brought to equilibrium. it is then s
tino4ka555 [31]

Given:

k = 100 lb/ft, m = 1 lb / (32.2 ft/s) = 0.03106 slugs 

Solution:


F = -kx 
mx" = -kx 
x" + (k/m)x = 0 

characteristic equation: 
r^2 + k/m = 0 
r = i*sqrt(k/m) 

x = Asin(sqrt(k/m)t) + Bcos(sqrt(k/m)t) 

ω = sqrt(k/m) 
2π/T = sqrt(k/m) 
T = 2π*sqrt(m/k) 
T = 2π*sqrt(0.03106 slugs / 100 lb/ft) 
T = 0.1107 s (period) 

x(0) = 1/12 ft = 0.08333 ft 
x'(0) = 0 

1/12 = Asin(0) + Bcos(0) 
B = 1/12 = 0.08333 ft 

x' = Aω*cos(ωt) - Bω*sin(ωt) 
0 = Aω*cos(0) - (1/12)ω*sin(0) 
0 = Aω 
A = 0 

So B would be the amplitude. Therefore, the equation of motion would be x = 0.08333*cos[(2π/0.1107)t]

This question is typical on some driver’s license exams: A car moving at 45 km/h skids 15 m with locked brakes. How far will the
sergiy2304 [10]

from kinematics equation if we know that final speed is ZERO and initial speed is given that due to constant deceleration the object will stop in some distance "d" and this distance can be calculated by kinematics

v_f^2 - v_i^2 = 2 a d

0 - v^2 = 2(a)d

here acceleration due to friction will be same at all different speed

so for 45 km/h speed the distance of stop is 15 m

while at other speed 112.5 km/h the distance will be unknown

now we will have

0 - 45^2 = 2(a)15

0 - 112.5^2 = 2(a)d

now divide above two equations

\frac{45^2}{112.5^2} = \frac{15}{d}

d = 93.75 m

So it will stop in distance 93.75 m
