Answer:
Heat generated in the rod is 8.33 watts.
Explanation:
It is given that,
Length of rod, l = 2 m
Area of cross section, 
Resistivity of rod, 
Potential difference, V = 0.5 V
The value of resistance is given by :
R = 0.03 ohms
Let H is the rate at which heat is generated in the rod . It is given by :
Since, 
So, the at which heat is generated in the rod is 8.33 watts. Hence, this is the required solution.
It is because we can't observe chemical properties from our naked eye. So, for observing these, we need to perform appropriate experiments that may need some specific conditions. So, they are harder to observe.
Hope this helps!
yup they r equal as mentioned above is equal magnitude and direction! so they r totally equal.
as one vector has 2 things which is used to define it ->
- Magnitude
- direction
so if both r equal then both vectors r equal vectors
During the first phase of acceleration we have:
v o = 4 m/s; t = 8 s; v = 13 m/s, a = ?
v = v o + a * t
13 m/s = 4 m / s + a * 8 s
a * 8 s = 9 m/s
a = 9 m/s : 8 s
a = 1.125 m/s²
The final speed:
v = ?; v o = 13 m/s; a = 1.125 m/s² ; t = 16 s
v = v o + a * t
v = 13 m/s + 1.125 m/s² * 16 s
v = 13 m/s + 18 m/s = 31 m/s
