According to Newton's first law of motion, if the net force acting on an object is zero, the object remains at rest, or if the object is already moving, continues to move in a straight line with constant speed. Galileo realized the motion of an object doesn't change until an unbalanced force acts on it.

What is the resistance of an electric frying pan that draws 12 amperes of current when connected to 120 Volt circuit

Blizzard [7]

10 ohms

Explanation

the resistance of an electric circuit is given by:

$\begin{gathered} R=\frac{V}{I} \\ where\text{ R is the resitance} \\ Vi\text{s the voltage} \\ I\text{ is the current} \end{gathered}$

Step 1

a) let

$\begin{gathered} R=R \\ V=120\text{ volts} \\ I=12\text{ Amperes} \end{gathered}$

b) now, replace in the expression

$\begin{gathered} R=\frac{V}{I} \\ R=\frac{120\text{ volt}}{12\text{ Amp}} \\ R=10\text{ ohms} \end{gathered}$

therefore, the answer is

10 ohms

How much work is needed to push a 117- kg packing crate a distance of 2.75 m up an inclined plane that makes an angle of 28 o wi

Nataly_w [17]

Answer:

$W_{tot,min} = 1481.372\,J$

Explanation:

The minimum total work is the work needed to counteract the work associated with the weight:

$W_{tot, min} = W_{F}$

$W_{tot,min} = m\cdot g\cdot \sin \theta \cdot \Delta s$

$W_{tot,min} = (117\,kg)\cdot (9.807\,\frac{m}{s^{2}} )\cdot (\sin 28^{\textdegree}) \cdot (2.75\,m)$

$W_{tot,min} = 1481.372\,J$
