According to ohms law, as the voltage increases across a 40 ohm resistor what happens to the current, resistors, and resistance
irakobra [83]

Answer:

As the voltage increases, the current flowing through the circuit increases while the resistance of the resistor remains constant.

Explanation:

Ohm's law states that the current flowing through a circuit is directly proportional to the applied voltage.

V = IR

where;

I is the current

R is the resistance

V is the applied voltage

Based on this law (Ohm's law), as the voltage increases, the current flowing through the circuit increases while the resistance of the resistor remains constant.

the gravational force is between two objects 18 N . if the distance between them is tripled and their masses are doubled. then w
Anni [7]
F_1 =  \frac{G m_1 m_2 }{r^2 } = 18N

F_2 = \frac{G M_1 M_2 }{R^2}

R = 3r

M_1 = 2m_1

M_2 = 2m_2

F_2 =  \frac{G 2m_1 2m_2}{(3r)^2} =  \frac{4}{9} *  \frac{G m_1m_2}{r^2} =  \frac{4}{9} * 18N

How is reflection of light used in research
mel-nik [20]

In order to read the publications of his peers, or read his own notes of the work
that he did on the previous day, or find his coffee mug on his desk in the lab, the
research scientist must arrange to have each of them illuminated with visible
wavelengths of light, and then he must catch the light reflected from each of them
with his eyes.

Why is a wedge one of the least efficient simple machines
dmitriy555 [2]
The wedge is an adaptation of the inclined plane. It can be used to raise a heavy load over a short distance or to split a log. The ideal mechanical advantage (IMA) of a wedge depends on the angle of the thin end. The smaller the angle, the less the force required to move the wedge a given distance through, say, a log.
