A catapult fires a 0.015kg stone at 70m/s.The spring constant of the catapult is 150N/M. Find the exrtention of the catapult.
adelina 88 [10]

Answer:

0.495m

Explanation:

The kinetic energy of the stone will be equal to the work done by the spring

Mathematically;

W = KE

1/2ke² = 1/2mv²

ke² = mv²

k is the spring constant = 150N/m

e is the extension

m is the mass = 0.015kg

v is the velocity = 70m/s

Substitute

150e² = 1/2 * 0.015 * 70²

150e² = 36.75

e² = 36.75/150

e² =  0.245

e = √0.245

e = 0.495m

Hence the extension of the catapult is 0.495m

Please answer the following two questions.

The regions of Great Lakes that are having a localized maximum in snowfall are called: B. snowbelts.

<h3>What is a snowbelt?</h3>

A snowbelt can be defined as a geographical region (area) near the Great Lakes in North America that is typically characterized by heavy localized maximum in snowfall, especially off the southern and eastern shores.

This ultimately implies that, snowbelts are the regions of Great Lakes that are having a localized maximum in snowfall.

In conclusion, hurricanes are more likely to form in the tropical Atlantic during a La Nina year because it weakens the wind shear.

as the trait is dominant and controlled by a single gene,the mutation must have occurred on both diploid copies. true or false?
GenaCL600 [577]

Answer:

False

Explanation:

A dominant trait is a trait that is inherited from parents. It is a trait that is obtained from a particular copy or type of a gene that overshadows or overwhelms the effects of another type or copy of that gene. Dominant traits are controlled by a single gene.

Therefore , as the trait is dominant and controlled by a single gene,the mutation must have occurred on both diploid copies is a false statement.
