Answer:
Negative
Explanation:
Liquid electrolyte inside battery has work to transfer the charge from one terminal to other terminal..
So here this is carried out by the charge which has more mobility and it must be more in numbers.
So here for more mobility we have to take the negative charge or free electrons present in the electrolyte which carry electricity from one terminal to other terminal with least resistance
so here correct answer would be
b.) Negative
Answer:
The car travels the distance of 225m before coming to rest.
Explanation:
Here,
v = 45m/s
t = 5s
d = v × t
Therefore,
d = 45 × 5
= 225m

Answer:
It's STERIC NUMBER.
Explanation:
The steric number is the number of shared pairs of electrons on a central atom of a molecule (σ sigma bond) plus the number of lone pairs on the central atom.
The object with the greater mass should be attached to the spring with the smaller spring constant, so that the resulting spring-object system has the greatest possible period of oscillation.
Answer: Option D
<u>Explanation:
</u>
According to the simple harmonic motions, from physics, it gives a relation between deformation force and the deflection. The more deflection results in more time period of oscillation.
F = - k x
where ‘k’ is the spring constant, and ‘F’ is the deformation force.
So, deflection is directly proportionate to forces, and inversely proportionate to its spring constant. Hence, we can derive that the force must be maximum, and hence weight must be maximum, with the spring constant lesser. Then, the deflection will be high. So, time period increases.
