Answer:

When the battery is almost fully charged.

Explanation:

A battery is a term used to describe any device that has the capability to convert chemical energy through an oxidation-reduction(redox) reaction taking place within the electrical circuit.

A battery usually have two ends, named as a cathode electrode(Positive) and an anode(negative) electrode. Batteries usually give off the most gas when they are almost fully charged, that is while it is advisable not to over charge a battery.

You need to know the height of a tower, butdarkness obscures the ceiling. You note thata pendulum extending from the ceiling alm

AysviL [449]

Answer:

The towers height is 322m

Explanation:

We can assume that a simple pendulum hangs from the top of the tower.

In this case, the length of the pendulum will be the same as the height of the tower.

We will use the next expression then:

$T=(2pi)(\sqrt{L/g})$

Where T is the period, L is the pendulum length and g is the gravity $(9.81m/s^2)$

From the previous expression we will have then that the length will be:

$L=(g)*((T/2pi)^2)$

Replacing:

$L=(9.81m/s^2)*((36s/2pi)^2)$

The towers height will be then: 322m

When the plutonium bomb was tested in New Mexico in 1945, approximately 1 gram of matter was converted into energy. Suppose anot

gayaneshka [121]

Answer:

The value is $E = 1.35 *10^{14} \ J$

Explanation:

From the question we are told that

The mass of matter converted to energy on first test is $m = 1 \ g = 0.001 \ kg$

The mass of matter converted to energy on second test $m_1 = 1.5 \ g = 1.5 *10^{-3} \ kg$

Generally the amount of energy that was released by the explosion is mathematically represented as

$E = m * c^2$

=> $E = 1.5 *10^{-3} * [ 3.0 *10^{8}]^2$

=> $E = 1.35 *10^{14} \ J$

Which observation did researchers make in studies on separated twins ?

choli [55]

Depending on whether they where conjoined initially, or where born separately really changes the answer of this question. Although studies show that twins generally have a kinetic link, more practical research says that twins are 25% more likely to both be left handed, which is a recessive gene, they are also more likely to die in child birth, twins are more likely to understand and be biligual, along with many other advantages twins may have.
