Jason applies a force of 4.00 newtons to a sled at an angle 62.0 degrees from the ground. What is the component of force effecti
Andreas93 [3]
Answer: 1.88 N

Explanation:

Data:

Force = 4.00N
angle = 62°
horizontal force = ?

Solution:

The trigonometric ratio that relates horizontal - leg to hypotenuse is the cosine.

That ratio is:

                        horizontal - leg
cos(angle) = -------------------------
                          hypotenuse

So, applied to the force, that is:

                             horizontal force
cos (angle) = -----------------------------------
                                 total force

So, clearing the horizontal component you get:
                                         
horizontal force = force * cos (angle)

Substitute the data given:

horizontal force = 4.00N * cos(62°) = 4.00N * 0.4695 = 1.88 N

Answer: 1.88N

Suppose you need your silicon circuit element to run continuously for 3 minutes before it shuts off long enough to cool back dow
Zigmanuir [339]

The maximum rate at which energy can be added to the circuit element mathematically given as

MER=5.044 \times 10^{-4} \mathrm{~J} / \mathrm{sec}

<h3>What is the maximum rate at which energy can be added to the circuit element?</h3>

Generally, the equation for P is  mathematically given as

P=\ln s \frac{\Delta T}{\Delta t}

Therefore

Rate\ of\ Change\ of\ Temp =\frac{p}{lnS}

\frac{p}{lnS}=\frac{7.4 \times 10^{-3}}{23 \times 10^{-6} \times 705}

\frac{p}{lnS}=0.456^{\circ \mathrm{c}} / \mathrm{sec}

Max temp Change

MaxT=5.6^{\circ} \mathrm{C}

\text { time }=3 \times 60

t=180s

In conclusion, Max Energy Rate

MER =23 \times 10^{-6} \times \frac{301 \times 5.6}{180}

MER=5.044 \times 10^{-4} \mathrm{~J} / \mathrm{sec}

Where is the net force?
anyanavicka [17]
The net force is the sum of all forces and it acts on the center of mass.
If the two forces have the same magnitude but opposite directions the sum of both forces is zero.
