A. True, a galvanometer is a device used to measure electrical currents
yan [13]3 years ago
5 0

Answer:

True.

Explanation:

Current may be defined as the amount of charge flowing per unit time. The S.I. unit of current is ampere. The current in a circuit can be calculated by the formula I = Q/T.

Galvanometer is a device that are used to measure the small amount of the electric current. The deflection in the galvanometer confirms that the current is flowing in the particular electric circuit.

Thus, the correct answer is option (a).

Which features form near convergent oceanic plates? Select the two correct answers.
Zepler [3.9K]

trench

volcanic arc

Features that will form near convergent oceanic plate boundary is a  trench & volcanic arc

Explanation:

A trench is formed because at the boundary where the two tectonic plates are colliding, there so much stress such that the two plates warp downwards and form a depression all along the boundary. This is a mid-ocean trench. This is as opposed to a mid-ocean ridge that forms at a divergent boundary.

A volcanic arc – a chain of volcanic mountains along the convergent boundary –is formed because the enormous stress along the boundary causes the formation of fissures. The subdued plate, as it dives into the mantle, melts into magma  that rises through these fissures. At the surface, the magma erupts violently into a volcanic mountain. Because there are many fissures along the boundary, several volcanic mountain chains will form along the boundary.

Theories of motivation that are based on biological drives have trouble explaining why people engage in behaviors that:______.
Rufina [12.5K]

Theories of motivation that are based on biological drives have trouble explaining why people engage in behaviors that do not satisfy biological needs.

Concept is normally depicted as a pyramid to that human motivation rests on a basis of basic biological needs that need to be satisfied for survival earlier than better-degree wishes may be addresses.

Power reduction procedures to motivation: when a few simple organic requirement is lacking, a drive is produced. Force idea specializes in organic wishes that produce unpleasant states of arousal. we're motivated to lessen the tension caused by this arousal. tension reduction has been proposed as a basic mechanism governing human behavior

The drive theory is primarily based at the concept of homeostasis, or the concept that the body actively works to maintain a certain state of balance or equilibrium. This idea is beneficial in explaining behaviors that have a sturdy organic or physiological component, along with hunger or thirst

If you were a scientist studying traits which are selected by humans instead of the environment, you would be studying the follo
Dvinal [7]

The correct answer is: Artificial selection (selective breeding).

Artificial Selection is a form of selection, totally influenced by human, in which traits that should be passed onto offspring are chosen by human. Selective breeding was used long before the genetics was discoverd. Farmers used individuals with beneficial traits, larger in size, with bigger fruit etc.

Hunting is also one type of selective breeding, since the hunters choose the animal and remove it from the population (gene pool), leaving the “weaker” to pass on to the next generation.
