Answer:

What is the greenhouse effect?

The greenhouse effect is the way in which heat is trapped close to Earth's surface by “greenhouse gases.”

Explanation:

These heat-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them. Greenhouse gases include carbon dioxide, methane, nitrous oxides, and water vapor. (Water vapor, which responds physically or chemically to changes in temperature, is called a "feedback.") Scientists have determined that carbon dioxide's warming effect helps stabilize Earth's atmosphere. Remove carbon dioxide, and the terrestrial greenhouse effect would collapse. Without carbon dioxide, Earth's surface would be some 33°C (59°F) cooler.

You throw a baseball (mass 0.145 kg) vertically upward. It leaves your hand moving at 12.0 m/s. Air resistance can be neglected.

Alchen [17]

Answer:

$h = 5.505\,m$

Explanation:

Let assume that ball begins its movement at a height of zero. The height can be found by energy approach, to be precise, by Principle of Energy Conservation:

$\frac{1}{2}\cdot (0.145\,kg)\cdot (12\,\frac{m}{s} )^{2}= \frac{1}{2}\cdot (0.145\,kg)\cdot (6\,\frac{m}{s} )^{2}+(0.145\,kg)\cdot (9,81\,\frac{m}{s^{2}} )\cdot h$

$h = 5.505\,m$

Momentum ap physics 1

11111nata11111 [884]

Answer:

The correct option is;

B. Object X travels at -2 m/s and object Y travels at 4 m/s after the spring is no longer compressed

Explanation:

The given parameters are;

The mass of object Y = M

The mass of object X = 2·M

The initial velocity of object X and object Y = 0 m/s

Let A represent the velocity of object X after the spring is released and B represent the velocity of object Y after the spring is released, therefore, by the principle of the conservation of linear momentum, we have;

(M + 2·M) × 0 = M × B + 2·M × A

∴ (M + 2·M) × 0 = 0 = M × B + 2·M × A

M × B = -2·M × A

∴ B = -2·A

Therefore, the velocity of the object Y = -2 × The velocity of the object X

Whereby the velocity of the object X = -2, The velocity of the object Y = -2 × -2 = 4

Which gives, object X travels at -2 m/s and object Y travels at 4 m/s after the spring is no longer compressed.

an astronaut in the satellite releases a pencil out of the satellite in space. will the pencil fall on the earth?

MAXImum [283]

No, it will not fall. The pencil will remain at zero speed relative to the spacecraft and will orbit the earth with the spacecraft.
