Answer: The current will flow from the negative to the positive terminal as fast as possible. This will wear out the battery quickly.
Explanation:
Explanation:
Given that,
Displacement in ice block,
Force exerted by water,
To find,
Work done by the force during the displacement.
Solve,
We know that the product of force and displacement is called work done. It is also equal to the dot product of force and displacement as :
We know that, i.i = j.j = k.k = 1
So, the work done by the force on the block during the displacement is 4181 Joules.
Answer:
Usually, zeroes are found to the right of a decimal point in significant numbers if you have something like (exaggerated example of course), which is when you have a number that is very very close to the integer before it, but isn't that integer.
Answer:
<h3><em>
468,000,000 m/s</em></h3>
Explanation:
According to newtons first law of motion;
Force = mass * acceleration
F = ma
where a = v-u/t
v is the final velocity
u is the initial velocity
t is the time taken
F = m(v-u/t)
Ft = m(v-u)
Given parameters;
F = 910,000N
t = 120m = 120 *60 = 7200secs
m = 1400kg
u = 0m/s
Required parameter
Final velocity v
Substituting the given parameters into the formula to get v;
Ft = m(v-u)
910,000 * 72000 = 1400(v-0)
910,000 * 72000 = 1400v
v = (910,000 * 72000)/1400
v = 910,000 * 720/14
v = 910,000 * 60
<em>v = 468,000,000 m/s</em>
<em></em>
<em>Hence the final velocity of the drag racer is 468,000,000 m/s</em>
