Answer:
The potential difference across iron wire is 133.95 V
Solution:
As per the question:
Length, l = 2.97 m
Diameter. d = 0.88 mm =
Voltage, V = 157 V
Now,
We know that the resistivity of iron,
Resistivity of copper,
Now,
The potential difference across the iron wire:
V' =
V' =
Answer:
Explanation:
Simply put, because weight is a kind of Force.
The force of gravity increases with mass, but decreases with increasing distance between objects.
it is c. safest when passing a large truck
hope this helps* :)
To calculate the horizontal distance traveled by the shot if it leaves the athlete's hand at a height of 2.20 above the ground we can get the root of the quad equation for time are t=-0.24 or t =1.84 taking the t = 1.84, so the equation will be:
x = 15.6cos(30) * 1.86, x = 24.79m
