In our current view of the Universe there are 2 possible futures. One possiblity is that the Universe will come to an end in the opposite of a Big Bang called The Big Crunch. The other possibility is that we live in an Eternal Universe that will never come to end.

i hope this helps :)

A string attached to an airborne kite is maintained at an angle of 41 degrees with the horizontal. If a total of 152 m of string

satela [25.4K]

Answer:

The horizontal displacement is $Adj = 114.71 \ m$

Explanation:

From the question we are told that

The angle at which the string is maintained is $\theta = 41 ^o$

The length of string reeled in is $l = 152 \ m$

Using the SOHCAHTOA formula

We have that the hypotenuse(Hyp) is l = 152

Hence the horizontal displacement of the kite which is the Adjacent(Adj) can be evaluated as

$cos \theta = \frac{Adj}{Hyp }$

substituting values

$cos(41) = \frac{Adj}{152}$

=> $Adj = 114.71 \ m$

As you drive away from a radio transmitter, the radio signal you receive from the station is shifted to longer wavelengths.

mylen [45]

Answer:

True

Explanation:

${Apparent}.wavelength = (True.wavelength)(1 +\frac{recession.velocity}{wave.speed})$

As one drive away from the radio station, the recession velocity increases and causes the apparent wavelength to increase accordingly, which in turn causes the True wavelength received from the radio station to increase as well because of their direct relationship as shown in the equation above.

All digits shown on measuring device, plus one estimated digit, are considered_______.

vichka [17]

Significant

Explanation:

All the digits shown on a measuring device and one estimated digit are all considered to be significant.

A significant digit is a set of values that shows how precise a measurement is reported.

Measuring devices such as calculators gives their values in significant digits.

Non- zero digits in a measurement are always significant.
Zero's before a decimal are not significant. Those after a number in a decimal are significant.
Zero's between digits are significant.

How does the mass of an object change the gravitational pull on two objects in a system? How does the distance between objects i

LuckyWell [14K]

Answer:The greater the mass, there greater then gravitational pull on their objects.

There greater the distance,the lower the gravitational pull between the object

Explanation:

Gravitational pull(force) is directly proportional to the products Of The masses. therefore if the mass increase,the gravitational pull(force) also increases.

Gravitational pull(force) is inversely proportional to distance.if the distance between the objects increases,the gravitational pull(force) decreases .
