Answer:

225

Explanation:

The period of rotation of Venus is 243 Earth days, which is longer than the 225 days it takes the planet to orbit the sun. Moreover, the rotation is in the opposite direction from other planets in the solar system.

The thermal energy in a hot iron flows into a shirt. what can possibly be said about this situation

Rainbow [258]

The correct answer for this question would be option A. When the thermal energy in a hot iron flows into a shirt, what we can possibly say about this situation is that, the iron is warmer than the shirt. The transfer of heat from the iron to the shirt is called heat conduction. Hope this answer helps.

Please answer and explain the equations of how you got the answer

Dima020 [189]

Answer:

a) H=277113.45m

b) t = 142.09 seconds

Solution

In this question we have given

initial speed, v= 1.7x10^3m/s

angle of projection with ground, α= 55 degree

a) Neglecting air resistance, horizontal component of velocity is given as

$V(h)=vcos\alpha$ ............(1)

put value of v and α in equation(1)

$V(h)=cos 55\times1.7x10^3m/s$

V(h) = 975.08 m/s

Now, horizontal range is given as

$H = V(h) \times t$

$H = 975.08 \times t$

= 975.08t m .... (1)

b) Time of flight

Vertical component of velocity is given as

$V(v)=vsin\alpha$ ............(1)

$V(v)=vsin55\times1.7x10^3m/s$

V(v) = 1392.5585 m/s

We know that time to reach at maximum height is given by formula

$t=\frac{V(v)}{g}$

t= (1392.5585 m/s)/9.8m/s^2

time to reach at maximum height,t = 142.09seconds

Total time in air 2t = 284.19 seconds.

put value of t in equation (1)

Therefore horizontal range is given as

$H=975.08m/s\times284.19s\\H=277113.45m$

What is time dilation? Is that a thing only in the movies? I need a good explanation that is simple enough for me

Naily [24]

Time dilation is the slowing of the passage of time at high speeds. The faster the object moves, the greater the amount of time dilation. Time dilation, in part, accounts for the constant speed of light, regardless of the light's source and regardless of the observer's perspective.
