Answer: 2.55meter
Explanation: Using the second equation of motion.
S{hieght} = U*t + {g*t²}/2
Where U is initial velocity =0m/s
g is acceleration due to gravity 10m/s²
t is time 1secs
So we have,
hieght = 0 + {g*t²}/2
hieght = {10*(1)²}/2
Total hieght travelled is 10/2
Which is 5 meter.
But we are asked to find the hieght above the window which as a hieght of 2.45meter.
So,
hieght above window would be
{5 - 2.45}meter
Which is 2.55 meter.
A I think because sublimation is when something skips melting and goes directly to vapor
The answer is a Mid-Ocean ridge.
Decrease the work being done and decrease the time in which the work is to be completed.
Answer:
21.2 m
Explanation:
The current in the wire is given by Ohm's law:
where V is the voltage of the battery and R is the resistance of the wire.
The resistance of the wire is directly proportional to the length of the wire, so we can write:
where k is a constant and L is the length of the wire. Substituting into the first equation,
We can rewrite this equation also as
where the term on the left is a constant (because the voltage of the battery does not change). So, we can write:
where:
is the current in the first situation
is the length of the wire in the first situation
is the current in the second situation
is the length of the wire in the second situation
Re-arranging the formula, we can find the value of L2:
