Answer:
The Storm Surge of a hurricane
Explanation:
A hurricane can ultimately cause a tsunami and is just as deadly.
Answer:
The velocity of wind with respect to cyclist is .
Explanation:
speed of cyclist = 12 km/h east
speed of wind = 5 km/h south west
Write the speeds in the vector form
The velocity of wind with respect to cyclist is
C a sliding Door ig idk tell me the right answer
Answer:
Explanation:
ME initial = ME final
PE initial + KE initial = PE final + KE final
There's no kinetic energy the moment Jorge is at the top of the ramp therefore KE initial = 0
PE initial = PE final + KE final
Assuming the bottom of the ramp is h = 0 we can then say PE final = 0
PE initial = KE final
Write the equations out.
mgh = (.5)mv^2
They tell us potential energy is 6000J therefore that portion of the equation is already "solved"
6000 = (.5)mv^2
Plugin the values
6000 = (.5) 70 v^2
Solve for v
6000 = 35v^2
171.43 = v^2
13.1 = v at the bottom of the slope
Solving for KE we get
(.5) m v^2
Plugin the value from the previous problem and solvee!
Answer:
ΔT = 1ºC
, 2ºCand 3ºC
Explanation:
In this exercise they indicate the specific heat of lithium
let's calculate the temperature increase as a function of the heat introduced
Q = m ΔT
ΔT = Q / m c_{e}
calculate
for Q = 3.5 J
ΔT = 3.5 / (1 3.5)
ΔT = 1ºC
For Q = 7.0 J
ΔT = 7 / (1 3.5)
ΔT = 2ºC
for Q = 10.5 J
ΔD = 10.5 / (1 3.5)
ΔT = 3ºC
we see that this is a straight line, see attached
