Answer:
The correct answer is "24 V".
Explanation:
The given values are:
Current,
I = 0.50 A
Resistance,
R = 12 W
As we know,
⇒
On substituting the given values, we get
⇒
⇒
⇒
Physical change
Because it's changed by heat
Answer:
50.67
Explanation:
L = 4 m
Let the mass of small length dx is dm.
So, dm = ρ(x) dx
Integrate on both the sides within proper limits
m = 40 + 32 / 3 = 152 / 3 = 50.67
Kinetic Energy = 1/2mv^2
M= mass
V=velocity
