A 0.10 newton spring toy with a spring constant of 160 newtons per meter is compressed 0.05 meter before it is launched. When re

Answer:

(1) V = 0.2 J (2) 0.05J

Explanation:

Solution

Given that:

K = 160 N/m

x = 0.05 m

Now,

(1) we solve for the initial potential energy stored

Thus,

V = 1/2 kx² = 0.5 * 160 * (0.05)²

Therefore V = 0.2 J

(2)Now, we solve for how much of the internal energy is produced as the toy springs up to its maximum height.

By using the energy conversion, we have the following

ΔV = mgh

=(0.1/9.8) * 9.8 * 1.5 = 0.15J

The internal energy = 0.2 -0.15

=0.05J

Winds that blow from the north and south poles

Gennadij [26K]

Winds that blow from the north and south poles would be called katabatic winds. I'm not sure if I spelled that right, but that's the answer I hope.

The study of how the moon causes tides in Earth's oceans represents an intersection of which two fields of science?

Delvig [45]

Moon tides or lunar tides are caused by the pull of gravity between the moon and earth. The moon will exert a gravitational pull on earth and the earth also pulls the moon towards itself. One of the results is that the moon is near the earth and the other one, the oceans tide. Even though the earth can hold any object within ts proximity, the ocean is partly attracted due to its liquid property. At night, the ocean tends to be attracted to the moon by creating a bulge and assigning it as ‘high tide’. This is due to the strong gravitational pull of th moon to the earth. The answer is letter D.
