The earth tilt about 23 degrees which leads to the formation of seasons on earth.

<h3>At what degree the earth tilt?</h3>

This is tilted at 23 degrees from the vertical. The northern hemisphere is in the winter season.

This is the path as the earth revolves around the sun. It takes 1 year to complete this path.

This is the path as the earth rotates around its.

So we can conclude that the earth tilt about 23 degrees which leads to the formation of seasons on earth.

A water balloon launcher uses an elastic band with a spring constant of 115 N/m. To use the launcher, you stretch the band back

Lorico [155]

Here elastic balloon launcher will behave like an ideal spring

so here we have

spring constant k = 115 N/m

mass of balloon = 1.3 kg

Part a)

Stretch in the band is given as

x = 0.8 m

now the force on the balloon is given by

F = k x

now from above

$F = (115) (0.8) = 92 N$

so it will exert 92 N force on it

Part b)

Elastic potential energy is given as

$U = \frac{1}{2}kx^2$

so here we have

$U = \frac{1}{2}(115)(0.8)^2$

$U = 36.8 J$

Part c)

Here in this case we can say that kinetic energy gained by the balloon must be same as the elastic potential energy stored in the rubber because there is no energy loss in this system

So kinetic energy = 36.8 J

Part d)

As we know by the formula of kinetic energy

$K = \frac{1}{2}mv^2$

$36.8 = \frac{1}{2}(1.3)v^2$

$v = 7.52 m/s$

so speed of the balloon will be 7.52 m/s
