Answer:
2N
Explanation:
subtract rthe two forces to see which is greater
4-2=2
The answer is as voltage increases current increases and therefore resistance would remain constant
Answer:
The right solution is:
(a) 2.87 eV
(b) 1.4375 eV
Explanation:
Given:
Wavelength,
= 433 nm
Potential difference,
= 1.43 V
Now,
(a)
The energy of photon will be:
E =
=
or,
=
=
(b)
As we know,
⇒
By substituting the values, we get
⇒
⇒
or,
⇒
⇒
This may helpv^2=u^2+2as. v=0 at top of flight. a=acceleration of gravity(vo^2)/2a=s.
