About 50 years ago, mounting evidence was suggesting
that the temperature of Earth's surface has been sharply
increasing for the past couple of centuries. Nowadays,
additional evidence no longer suggests it; it confirms it.

Today's mounting evidence suggests that human activity is
responsible for the increase, but that the increase eventually
spells curtains for much of human activity.

A bug splats against the windshield of a car traveling at high speeds down a backcountry road. Which statement correctly compare

zvonat [6]

Answer:

C. The bug's change in momentum is equal to the car's change in momentum.

Explanation:

As we know by Newton's 2nd law

$F = \frac{\Delta P}{\Delta t}$

here we have also know that when car hits the bug then force applied by wind shield on the bug is same as the force applied by the bug on the car's wind shield as per Newton's III law

$F_{12} = F_{21}$

so we know that

$\frac{\Delta P_{12}}{\Delta t} = \frac{\Delta P_{21}}{\Delta t}$

so we have

$\Delta P_{12} = \Delta P_{21}$

so correct answer will be

C. The bug's change in momentum is equal to the car's change in momentum.

Answer:

C. The gravity acceleration is in the same direction as the force of gravity, and thus toward the center of the earth.

Explanation:

[ More info.- It doesn't affect the body when it is at the rest, and when it is in motion, it acts toward the center of the Earth and it's component is known as "Centripetal force" ]

Nookie1986 [14]

Answer: exactly 10.0 grams.

Explanation: The law of conservation of matter states that matter cannot be created or destroyed in a chemical reaction. Therefore, the total mass of the reactants must be the same as the total mass of the products.
