Answer:

Make a graph for better visual representation.

Explanation:

Presenting data like that would require someone to see the increase. The best way would be a graph to be shown, to really show the impact by the line going up in the graph.

Answer these questions "type of heat transfer that occurs between the sun and venus" "measure of the average value of the kineti

AveGali [126]

1) The type of heat transfer is radiation (ie the sun's rays)
2) Not entirely sure what you mean but it is possible with this equation: KE = 3/2kT with k being the Boltzmann's Constant and T the temperature in Kelvins
3) True? Not really a question.
4) This would be emissivity
5) Thermal Energy
6) Celsius
7) A thermometer

A ball is thrown from a top of a building of height 20m. If the initial velocity of the ball is 15m/s at 370 above the horizonta

Lesechka [4]

Explanation:

Givens:

$h = 20 \: m$

$v _{ix} = 15 \cos(37) = 11.97$

$v _{iy} = 15 \sin(37) = 9.03$

$a _{y} = - 9.8$

Let t=2 be the final velocity. Since Velocity stays the same horizontal , acceleration due to gravity changes the vertical direction

Use this equation

$v _{y} = v _{iy} + a _{y}(t)$

Plug in the knowns

$v _{y} = 15 \sin(37) +2 ( - 9.8)$

$v _{y} = - 10.57$

So the velocity in the y direction at 2 seconds is -10.57

The velocity in the x direction at 2 seconds is 11.97

Use the Pythagorean theorem to find the total velocity

$v = \sqrt{( - 10.57) {}^{2} + (11.97) {}^{2} }$

$v = 15.97$

b. The range at which it strike the ground.

We need to find when the velocity at the top is zero.

Using the y direction,

$0 = v \sin( 37 ) - 9.8(t)$

$t = 0.921$

Next, find the height of the max.

$h = \frac{1}{2} ( 9.8)(0.921) {}^{2} = 4.16$

So the total distance is 4.16+20= 24.16

Next to find the total time it falls

$24.16 = \frac{1}{2} (9.8) {t}^{2}$

$t = 2.2$

So our total flight time is

$3.141$

Range is

$v \cos(37) (3.141) = 37.63$

The sense of smell helps protect us against danger. Explain why.

atroni [7]

Well we can always smell things like if food smells bad or if we smell something we have to know whether that smell is good or bad. You could be able to smell animals that are dangerous. Or animal droppings, to know what animal it is if you are in danger.
