Answer: 1990

Explanation: Wikipedia say “The Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned both as a vital research tool and as a public relations boon for astronomy. The Hubble telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope.”

Compare and contrast the energy transfer of a roller coaster to that of a pendulum

Softa [21]

When the pendulum and roller coaster move to the top, its has more potential energy whereas when comes to the bottom has more kinetic energy.

<h3>Compare and contrast the energy transfer of a roller coaster to that of a pendulum:</h3><h3>What is the transfer of energy in a roller coaster?</h3>

The transfer of potential energy to kinetic energy occur when the roller coaster move along the track. As the motor pulls the cars to the top, the body has more potential energy whereas when the body comes to the bottom , it has kinetic energy in the object.

<h3>What is the energy transfer in a pendulum?</h3>

As a pendulum swings, its potential energy changes to kinetic energy and kinetic energy changes into potential energy. At the top more potential energy is present.

So we can conclude that When the pendulum and roller coaster move to the top, its has more potential energy whereas when comes to the bottom has more kinetic energy.

A 60-kg person is traveling in a car moving at 16 m/s, when the car hits a barrier. The person is not wearing a seat belt, but i

marin [14]

Using conservation of momentum, we can solve for the force that the air bag exerts on the person.

Recall the equation for momentum (p):

$p = mv = F*dt$

We can solve for total momentum, then divide by out time interval. This gets us:

$(60kg)(16m/s) = F(0.2s)


F = 4800N$

F = 4800N

4. Can an object's displacement be negative? What does the sign indicate about the<br> displacement?

faltersainse [42]

Displacement can be positive OR negative. The sign implies the direction of the displacement. Negative means that is is moving to the left (sometimes called West) or down (sometimes called South); positive means that is moving to the right (sometimes called East) or up (sometimes called North).

A charged comb often attracts small bits of dry paper that then fly away when they touch the comb. Explain why that occurs.

MAVERICK [17]

Explanation:

Since the comb has a net charge, it attracts the paper, which has a net charge equal to zero. When the paper touches the comb, an electrical interaction is established between the charge of the comb and the neutral paper, because of this, the paper now has a net charge with the same sign of the comb and they repel.

Elements from opposite sides of the periodic table tend to form ________.

Ivenika [448]

Ionic compounds is your answer. What happens is one atom donates electron(s) to the other atom, making one positive and the other negative. The opposite atoms attract, forming an ionic bond.

Hope this helps! :)
