Answer:
12 ohms
Explanation:
Ohm's Law tells the relationship between voltage, current, and resistance.
It can be written in three different ways, depending on which ones you know,
and which one you want to find.
Here's the one we need:
Resistance = (voltage) divided by (current)
= (120 V) / (10 Amp)
= 12 ohms .
Answer:
20N
Explanation:
Force applied by Samantha = 10N
Force applied by Emily = 10N
Since both Samantha pushes the box of textbook in the same direction; their forces are additive.
Net force applied on box = Force applied by Samantha + Emily
Force is a pull or push on a body
Net force = 10N + 10N = 20N
A geologist is studying rock layers in an old river bed, and he finds a fossil of a fish and a horsetail rush in the same rock layer. According to the law of faunal and floral succession, the geologist can assume that the rock containing the fossils may date back as far as the <span>Devonian period</span>.
