Answer:
35m
Explanation:
25m + 10m = 35m east.
*(adding since it's in the same direction)
Q = mass water x specific heat water x delta T.
<span>714,000 = mass water x specific heat water x 30.
Substitute specific heat water and solve for mass water.</span>
Lightning rods provide low resistance paths to the ground that’ll be used to conduct the enormous electrical currents when lightning strikes happen. So the system will attempt to carry the harmful electrical current away from it and safely to ground. The system will have the ability to handle enormous electrical currents associated with the lightning strikes, if they contact a material that isn’t a good conductor then the material will suffer massive heat damage. So the lightning rod system is considered the best conductor & this allows the current to flow to the ground without causing any massive heat damage.
Answer:
<u>We are given: </u>
initial velocity (u) = 0 m/s
final velocity (v) = 10 m/s
displacement (s) = 20 m
acceleration (a) = a m/s/s
<u>Solving for 'a'</u>
From the third equation of motion:
v² - u² = 2as
replacing the variables
(10)² - (0)² = 2(a)(20)
100 = 40a
a = 100 / 40
a = 2.5 m/s²
