The gravitational force between two asteroids is 100N. What would the force be if the distance between the asteroids was cut in

half?

4 0

The gravitational forces between two masses are inversely proportional to
the square of the distance between the centers of the masses.

So if the distance between the <u>centers</u> of the asteroids is multiplied by 1/2,
then the gravitational forces between them are multiplied by ...

                         1 / (1/2)²  =  (2)²  =  4 .

The new force is  (100N)  x  (4)  =  <em>400N</em>.

What are the basic si units for the wavelength of light?
noname [10]

Answer:

Meter (m)

Explanation:

The wavelenght of a light wave is a measure of the distance between two successive crests (or two successive troughs) of a light wave.

Since the SI units for the distance is the meter (m), then the SI unit for the wavelength is also the meter (m).

Wavelength is related to the frequency of the light wave by:

\lambda=\frac{c}{f}

where

c is the speed of light

f is the frequency of the light

A gas sample is heated from -20.0°C to 57.0°C and the volume is increased from 2.00 L to 4.50 L. If the initial pressure is 0.14
Svetach [21]

Answer:

The answer is e.

Explanation:

We take:

T_{1}=253K

V_{1}=2.00 l

P_{1}=0.14atm

V_{2}=4.50 l

T_{2}=330K

Taking the gas as an ideal gas, we can use the ideal gas law:

\frac{PV}{nRT}

⇒ n=\frac{P_{1}V_{1}}{RT_{1}} ⇒ n=0.013mol

Then:

P_{2}=\frac{nRT_{2}}{V_{2}} ⇒ P_{2}=0.0811 atm

Taking R=0.08205atmL/molK.

2. How long will it take for a ball thrown vertically upward with an initial velocity of
KengaRu [80]

Answer:

13.33 seconds

Explanation:

At maximum height, the equation of motion becomes:

<em> v = u + at</em>

Since the object was thrown vertically, the initial velocity (u) is zero and the acceleration (a) becomes the acceleration due to gravity (10 m/s2). The equation becomes:

<em>v = at</em>

<em>v = 480 k</em>m/hr = 133.333 m/s

    10t = 133.333

       t = 133.333/10

           t = 13.33 seconds.

<em>The time for the ball thrown vertically with a velocity of 480 km/hr to reach the maximum height is </em><em>13.33 seconds</em><em>.</em>
