When touched by a plastic straw, the metal sphere will do what?

I believe that if you touch a metal sphere with a plastic straw, the straw would not have enough strength to push it. So in that case, the metal sphere will not move and will stay in one place.

The less internal heat a jovian planet emits the more it stirs up its clouds.
g100num [7]
The correct answer would be false. The less internal heat a jovian planet emits the lesser it stirs up its clouds making the atmosphere hotter. All of the four Jovian planets have unique atmospheres. They have more or less the same structures but they differ in their average temperature. As the distance of the planet is closer to the sun the atmosphere would be cooler. These planets are Jupiter, Saturn, Uranus and Neptune. They do not have a solid structure instead they are primarily composed of helium and hydrogen which makes them gas giants or ice planets. They are larger in size than the remaining planets in the solar system.

Which of the following statements are true about the lenses used in eyeglasses to correct nearsightedness and farsightedness? (T
Slav-nsk [51]

Answer:

A: They produce a real image.

Explanation:

The images formed on the retina of the eye for a normal visibility must always be real.

Only a real image can be physically projected on any physical object whereas the virtual images are visible due to reflections.

  • The nearsightedness is corrected with the help of a concave lens since it is the condition of the eye lens remaining thick and curved to converge the rays entering the eyes after a shorter distance which results in their image formation even before the retinal surface so to initially diverge them a bit so that they converge on the retinal surface and form the image there we use concave lens. Vice-versa of the above justification in  the case of farsightedness.

A bungee jumper attains a speed of 30 m/s just as the bungee cord begins to stretch. If the period of stretch is 2 s while comin
Bogdan [553]

Answer:1.53g

Explanation:

average deceleration= ?

inial velocity: u=0

final velocity: v=30m/s

time: t=2seconds

The first law of kinematics :

v=u+at

find a the subject of the formula

a=v-u/ t

a=\frac{0-30} 2

a=-30/2

a=-15m/s^{2}

The deceleration about g(acceleration due to gravity) will be:

15/9.8

a constant current of 3 a for 4 hours is required to charge an automotive battery.if the terminal voltage is 10 t/2 v, where t i
Korvikt [17]

The charge transported as a result of charging is 43200C .

we can note the following data from the statement :

Current (i) = 3A

Time interval (t) = 4 hrs = 14400secs

As we know ,

Current is defined as the rate of flow of the charges between two points when a potential difference is applied between them.

Mathematically , it can be written as

Current(i) = charge (q)/ time(t)

Q = i × t

   = 3 × 14400

   = 43200 C

By dividing the value of the current passed through the circuit by the time for which the charge is passed gives out the value of the charge passed .
