It’s because conductors have nearly zero resistance to the flow of electrons that go through them. This leaves the electrons free to move and current can travel with full strength.

Which statement is true? CTP hydrolysis can be a source of chemical energy. dATP is the most common source of chemical energy in
Gemiola [76]

1. Statement A is true.

When GTP is hydrolysed, the free energy of hydrolyses is used to power or drive reactions that are favourable energetically.

2. Statement B it true.

ATP is a complex chemical that gives energy for the activities in many living cells. During hydrolyses, chemical energy stored in the energy-rich phosphoanhydride is released. Hence its a common source of chemical energy in cells.

3. Statement C is false.

The hydrolyses of ATP to ADP in the presence of phosphate, releases one mole of ATP which is estimated to be -57Kj/mol not 14Kj/mol. Below is the equation;

ATP + H20 -----> ADP + Pi + Free energy.

4. Statement D is false.

GTP stands for guanosine triphosphate.

ATP stands for adenosine triphosphate

ADP stands for adenosine diphosphate.

A boy twirls a 15-lb bucket of water in a vertical circle. If the radius of curvature of the path is 4 ft, determine the minimum
chubhunter [2.5K]

Answer:

11.35 m/s

Explanation:

Given,

Weight of the bucket = 15 lb

radius of curvature, r = 4 ft

Minimum speed of the bucket = ?

Using equation of centripetal acceleration

W=\dfrac{mv^2}{R}

15=\dfrac{\dfrac{m}{g}\times v^2}{4}

15=\dfrac{\dfrac{15}{32.2}\times v^2}{4}

v^2 = 128.8

v = 11.35\ m/s

Speed of the bucket  = 11.35 m/s
