Answer:
I think c is correct options....
Explanation:
The resistance of the wire increases with increase in temperature. The resistance does not depend on the weight of the wire. Therefore, the correct option is weight.
Answer:
The horizontal and vertical distances are x = 210 m and y = -240.35 m, respectively.
Explanation:
Using the equation of the displacement in the x-direction, we have:
(let's recall we have a constant velocity in this direction)

Where:
- v(ix) is the initil velocity in the x direction (v(ix) = 30 m/s)
- t is the time (t = 7 s)
Now, we need to use the equation of the displacement in the y-direction to find the vertical distance. Here we have an acceleration (g)

Where:
- v(iy) is the initial velocity at the y-direction. In this case, it will be 0
- t is the time
- g is the acceleration of gravity (g=9.81 m/s²)
Then, the vertical position at 7 s is:


Therefore, the horizontal and vertical distances are x = 210 m and y = -240.35 m, respectively. The minus sign means the <u>negative value in the y-direction.</u>

Answer:
The force required to maintain an object at a constant velocity in free space is equal to Zero.
Answer:
The Answer is B because the material the object is made of, the position, or the color have absolutely nothing to do with gravitational potential energy
The equation for power is P=VI, we can then rearrange V=IR and substitute I into the equation, this gets us V/R=I. Thus we get P=V^2/R
Next we convert kΩ to Ω. This tells us the resistor in Ω is 5600Ω.
Finally, plug into equation, we get P = (5V^2)/5600Ω.
P = 0.0044642857W
Hope this helps!
