How does the Foucault Pendulum show that the Earth rotates?

1 answer:

7 0

The Foucault Pendulum show that the Earth rotates because the pendulum would swing so slowly that it would appear to change direction as the Earth moved away.

<h3>How does the Foucault pendulum work?</h3>

The Foucault pendulum was able to demonstrate experimentally that the Earth revolves around itself with an angular velocity Ω, in a period of 23 hours, 56 minutes and 4 seconds.

Thus, Foucault knew that the longer the string attached to the weight, the slower the swing of his pendulum. He could attach the string above to an almost frictionless pin, and if he used a very large weight, the pendulum would swing so slowly that it would appear to change direction as the Earth moved away.

In pea plants, flowers are either white or purple; the purple color is produced by pigments called anthocyanins. The production

Hoochie [10]

Answer:

7/16

Explanation:

The proportion of the offspring from the cross that will have white flowers is 7/16.

The presence of anthocyanin which determines purple coloration is conditioned by the C_ and P_ alleles. It means that the absence of one or both of C and P will result in white flowers.

Two plants, each with CcPp are crossed:

CcPp x CcPp

Offpring

1 CCPP - purple

2 CCPp - purple

2 CcPP - purple

4 CcPp - purple

2 Ccpp - white

1 CCpp - white

1 ccPP - white

2 ccPp - white

1 ccpp - white

Proportion of offspring with white flowers = 7/16

Proportion of offspring with purple flower = 9/16

See the attached image for the Punnet's square analysis of the cross.
