Answer:
125 V
Explanation:
Given,
Power ( P ) = 500 W
Current ( I ) = 4 A
To fine : -
Potential difference ( V ) = ?
Formula : -
P = V I
V = P / I
= 500 / 4
V = 125 V
Therefore,
the potential difference across the ends of the heating element is 125 V.

I am just 13 and thanks for point
Answer:
ionic bond
Explanation:
ionic bond is the electrostatic attraction between oppositely charged ions, hence ionic bond is the answer.
v = u + at
25 = 0 + a(14)
a(14) = 25
a = 25/14
a = 1.71 (3sf)
explanation:
u use the equation of motions
v = u + at
v is final velocity, aka 25
u is initial velocity, which is 0 as it was initially at rest
t is time, which is 14s
then u sub in the values and calculate a
