A spring with a spring constant of 50 n/m is compressed 0.2m. if a mass of 0.4kg is connected to the spring, what is the maximum

Trava [24]

Use conservation of energy

$\frac{1}{2} k x^{2} = \frac{1}{2} m v^{2} \\ \\ v = \sqrt{\frac{k}{m} } x$

As shown in the diagram below, a rope attached to a 500.-kilogram crate is used to exert a force of 45 newtons at an angle of 65

kaheart [24]

Answer:

19.01 N

Explanation:

F = Force being applied to the crate = 45 N

$\theta$ = Angle at which the force is being applied = $65^{\circ}$

Horizontal component of force is given by

$F_x=F\cos\theta\\\Rightarrow F_x=45\times \cos65^{\circ}\\\Rightarrow F_x=19.01\ \text{N}$

The horizontal component of the force acting on the crate is 19.01 N.

Do you think that solids can undergo convection

Alex_Xolod [135]

Convection means the movement happens inside a fluid by the cause of too much heat and lesser density to rise, and also the colder cause denser materials to sink.
Thus, Solid cannot undergo convection because the molecules inside the solid are closer and can hardly move unlike liquid.
So, when the temperature got hotter or colder, the molecules on solid will only vibrate and not convert.
Therefore, this concludes that the solid do not undergo convection rather conduction of heat.

A) Draw a pie chart that represents the two types of lung cancer. Show your working.

Sphinxa [80]

Answer:

Please, check the image provided

Explanation:

Pie Charts

They are graphic representations of quantitative results from experimental or theoretical experiences. Instead of showing a table, it's usually preferred to show a graph where the viewer can easily understand the relative relations between the parameters under study.

The chart pie is a circular shape divided into sectors whose areas are proportional to the proportions between each parameter and the total. Since the whole sector of a circle has 360°, each sector will be a proportion or ratio of that angle.

The outcome shown in the table gives us these statistics:

Small Cell Carcinoma : 15%

Non-Small Cell Carcinoma : 85%

Each category has the following angles in the chart pie

Small Cell Carcinoma : 15%*360°=54°

Non-Small Cell Carcinoma : 85%*360°=306°

The first category is shown in blue and the second in green. Please check the image below.
