What discoveries support the idea of continental drift?

2 answers:

6 0

Answer: With the discovery of plate tectonics and the mapping of the earth into about 12 plates, plus the understanding that plates' movement caused earthquakes, Alfred Wegener's idea of " continental drift" looked less ludicrous than his contemporaries had thought.

MATH PHYS PLEASE HELP ME THANK YOU IN ADVANCE

Troyanec [42]

Explanation:

I don't know what values you have measured, or what <em>Ladybug Revolution</em> is, but I can show you the equations for rotational motion.

Angular displacement is:

Δθ = ω₀ t + ½ αt²

where ω₀ is the initial angular velocity, α is the angular acceleration, and t is time.

Assuming the radius is constant, the arc length is radius times angular displacement.

s = rΔθ

Using the equation for angular displacement, we can see that if two points have the same angular velocity and same angular acceleration, then they also have the same angular displacement.

Is it possible for a gas contained in a chamber to maintain a constant temperature while heat is being added to the gas? Explain

Evgesh-ka [11]

Answer:Yes

Explanation:

Yes it is possible for a gas contained in a chamber to maintain a constant temperature while heat is being added to the gas.A process in which temperature of the gas remains constant is called Isothermal Process.For an ideal internal energy is a function of temperature therefore internal energy remains constant while all the heat added is converted to do the work done by the system.

In 1869 Dmitri Mendeleev was trying to arrange the 65 known elements in a logical way. He arrived at the solution when he saw th

stellarik [79]

Answer: Creative thinking

Explanation:

It should be noted that, Creative Thinking is the method by which a problem is solved with the help of thinking skills.

The thought that is present in mind is tries in the practical life so that the problem can be solved.

Going by the question asked, Mandleev was trying to arrange elements in a logical way. He thought of arranging the elements based on the atomic weight.

This gives a good oexample of creative thinking in which the thinking is applied and a logical result is product of the thinking.

A 0.18-kg turntable of radius 0.32 m spins about a vertical axis through its center. A constant rotational acceleration causes t

borishaifa [10]

Answer:

Angular acceleration will be $18.84rad/sec^2$

Explanation:

We have given that mass m = 0.18 kg

Radius r = 0.32 m

Initial angular velocity $\omega _i=0rev/sec$

And final angular velocity $\omega _f=24rev/sec$

Time is given as t = 8 sec

From equation of motion

We know that $\omega _f=\omega _i+\alpha t$

$24=0+\alpha \times 8$

$\alpha =3rev/sec^2=3\times 2\times \pi rad/sec^2=18.84rad/sec^2$

So angular acceleration will be $18.84rad/sec^2$

Explain in detail why insulating you’re house will reduce your energy bills.

Anni [7]

Answer:

By insulating our homes, we reduce the demand for energy and burn less fuel, which helps combat climate change and protects the planet. Insulating the loft, walls and floor of your home is a great way to reduce energy bills every year from a one-off activity!

Explanation:

I really hope this helps! Stay safe! ✌
