The resistance of a piece of wire is given by
R= \frac{\rho L}{A}
where
\rho is the material resistivity
L is the length of the wire
A is its cross-sectional area

Substituting the data given by the problem, we can find the value of the resistance of the wire:
R= \frac{\rho L}{A}= \frac{(1.7 \cdot 10^{-8} m)(1.3 m)}{(8.36 \cdot 10^{-6} m^2)}=2.6 \cdot 10^{-3}\Omega

A ball is kicked off of a roof at 23 m/s [R 25° U]. What is the height of
Ymorist [56]

Answer:

Explanation:

Considering the fact that we ave been given an angle of inclination here, we best use it! That means that the velocity of 23 m/s is actually NOT the velocity we need; I tell my students that it is a "blanket" velocity but is not accurate in either the x or the y dimension of parabolic motion. In order to find the actual velocity in the dimension in which we are working, which is the y-dimension, we use the formula:

v_{0y}=v_0sin\theta and filling in:

v_{0y}=23sin(25) which gives us an upwards velocity of 9.7 m/s. So here's what we have to work with in its entirety:

v_{0y}=9.7m/s

a = -9.8 m/s/s

t = 2.8 seconds

Δx = ?? m

The one-dimensional motion equation that utilizes all of these variables is

Δx = v_0t+\frac{1}{2}at^2 and filling in:

Δx = 9.7(2.8)+\frac{1}{2}(-9.8)(2.8)^2 I am going to do the math according to the correct rules of significant digits, so to the left of the + sign and to 2 sig fig, we have

Δx = 27 + \frac{1}{2}(-9.8)(2.8)^2 and then to the right of the + sign and to 2 significant digits we have

Δx = 27 - 38 so

Δx = -11 meters. Now, we all know that distance is not a negative value, but what this negative number tells us is that the ball fell 11 meters BELOW the point from which it was kicked, which is the same thing as being kicked from a building that is 11 meters high.

On gasoline powered boats, when should the blower be activated
Verizon [17]
In gasoline powered boats, it is important to keep in mind the proper procedures in handling before activating the engine or your boat. Such as activating the blower. In activating the blower, it is advisable to turn it on after minutes of refueling and the engine should be activated afterwards. It is important to keep in mind to wait for a couple of minutes before turning it on because gasoline powered boats if not used or handled properly could cause harm such as explosion for it uses gasoline.
