Answer:
A fire hose must be able to shoot water to the top of a building 35.0 m tall ... Water enters this hose at a steady rate of 0.500 m3/s and shoots out of a round nozzle. ... I know that Flow rate=0.500 m3/s=A*V. I know the pressure needed to ... The first equation has no potential while the second has no kinetic.
Explanation:
Answer:
d. Can be replaced at the same rate or faster than they are used
Explanation:
I just took the test, and its the right answer. Your welcome ✌
Answer: 704
Explanation:Vi = 0 m/s
vf = 65 m/s
a = 3 m/s2
d = ??
vf2 = vi2 + 2*a*d
(65 m/s)2 = (0 m/s)2 + 2*(3 m/s2)*d
4225 m2/s2 = (0 m/s)2 + (6 m/s2)*d
(4225 m 2/m2)/(6 m/s2) = d
d = 704 m
Momentum of the wagon increases by (200 x 3)
= 600 newton-sec
= 600 kg-m/sec
Answer:
<h2>option C </h2><h2>decreasing its thickness and increasing its temperature. </h2>
Explanation:
<h2>Resistance is directly proportional to length and temperature of the wire and inversely to area.</h2>
<h3>if you increase the temperature the resistance will increase.(resistance is directly proportional to temperature)</h3>
<h3>if you decrease its thickness (area) then the resistance will increase ( resistance is inversely proportional to area)</h3>
hope it helps:)
