Answer:5 units
Explanation:
Given
magnitude of vector A
magnitude of vector B
Smallest value of vector addition can be obtained when they are at angle of
i.e.
where R is resultant vector
when two vectors are apart then they Produce minimum magnitude vector
Explanation:
Given that,
(a) Work done by the electric field is 12 J on a 0.0001 C of charge. The electric potential is defined as the work done per unit charged particles. It is given by :
(b) Similarly, same electric field does 24 J of work on a 0.0002-C charge. The electric potential difference is given by :
Therefore, this is the required solution.
Tectonic plates are always shifting
specific gravity of the unknown sample = 2.68
Explanation:
True weight of solid=31.6 N
Apparent weight=19.8 N
loss in weight= 31.6-19.8=11.8 N
Loss in weight= weight of the liquid displaced
so weight of water displaced= 11.8 N
now specific gravity= weight of object/ weight of liquid displaced
specific gravity= 31.6/11.8
specific gravity= 2.68
<span>The answer is Option a
Reason
The electron is moving closer to the nucleus. That is, in other words, it is moving to a lower energy level and will, therefore, give out energy When a transition gives out energy or in other terms it emits heat, it's exothermic. Hence the option a.</span>
