A student left a bar of chocolate in the sun on a hot day. As the chocolate melted, which property changed?

Physics

The property changed was its weight

The melted chocolate weighs the same, has an identical mass, and is still composed of chocolate.

Now it’s just melted chocolate instead of a candy bar and has thus changed shapes.

If the distance between two masses is tripled, the gravitational force between changes by a factor of
maw [93]

A. 1/9

Explanation:

The gravitational force between two objects is given by

F=G\frac{m_1 m_2}{r^2}

where

G is the gravitational constant

m1 and m2 are the two masses

r is the distance between the two masses

From the formula, we see that the magnitude of the force is inversely proportional to the square of the distance: therefore, if the distance is tripled (increased by a factor 3), the magnitude of the force changes by a factor

\frac{1}{r^2}=\frac{1}{3^2}=\frac{1}{9}

When figure skating how do you quickly transition from backwards to forwards without falling or just going in a circle? I'm fair
olga2289 [7]
I am a competitive figure skater.  There are certain turns you can use such as a mowhawk, where you set one foot down that is facing the opposite direction from which you are gliding.  There is a two foot turn, where you either go on or toes and turn backwards, or lean somewhat on your heals and turn forwards.  Use your hips to help turn.  And a 3 turn, which is basically a 2 foot turn on 1 foot.  But remember, it takes practice, and you may fall a couple times.

What us the difference between accurate data and reproducible data
Nikolay [14]

It's just in the name! Accurate data is helpful, and correct, but reproducible data is all of that, and is able to be given to other people through different sources! At least, that's what my understanding of them are. Hope it helps!

A wire loop with 70 turns is formed into a square with sides of length ???? . The loop is in the presence of a 1.20 T uniform ma
Oksi-84 [34.3K]

Answer:

l= 3.002 cm

Explanation:

Given that

n= 70 turns

B= 1.2 T

θ= 15°

I= 1.5 A

τ = 0.0294 N⋅m

Lets take length of sides is l.

We know that

τ  = n I A B sin θ

Area of square ,A= l²

Now by putting the value

τ  = n I A B sin θ

0.0294  = 70 x  1.5 x  l² x  1.2 x  sin 15°

l² = 0.000901 m²

l² = 9.01 cm²

l= 3.002 cm

What is the velocity of a penny dropped from the roof after 5 seconds?
Ksivusya [100]

Answer:

49 m/s

Explanation:

Acceleration = velocity / time

You should know accleration due to gravity is 9.8 m/s^2 and you're given t = 5, so you can solve for velocity:

9.8 = v / 5

v = 49
