timofeeve [1]
<span>The cause of albinism in one seal in a population of seals with similar coloring is gene mutation. Albinism is a recessive trait caused by a mutation in the gene for the enzyme which is important in melanin synthesis. Since melanin is a pigment responsible for hair and skin colour, the gene mutation will cause the absence of melanin and thus, albinism.</span>

A car is traveling at 40 m/s for 20 seconds. How far did it travel in this time?
barxatty [35]
<h3>Answer:</h3>

800 meters

<h3>Explanation;</h3>

<u>We are given;</u>

  • Speed as 40 m/s
  • Time as 20 seconds

We are required to determine the distance traveled

  • Speed refers to the rate of change in distance.
  • It is given by;

Speed = Distance ÷ time

Rearranging the formula;

Distance = speed × time

In this case;

Distance = 40 m/s × 20 sec

              = 800 meters

Thus, the distance traveled by the car is 800 m

Mr. Claspell moves 100 N of avocados straight up 2.0 meters.
solniwko [45]

Answer:

see the various answers below

Explanation:

From the given details, we can see that we are required to solve for the work done.

1. Mr. Claspell moves 100 N of avocados straight up 2.0 meters.

Work done= Force*Distance

Work done= 100*2= 200Joules

2. The Flash tackles the Reverse-Flash and pushes him 3.0 meters using a force of 200 N.

Work done= Force*Distance

Work done= 200*3= 600Joules

3. Darth Vader moves a large rock using force. That force is 3.0 N and he moves the rock 15 meters.

Work done= Force*Distance

Work done= 3*15= 45Joules

4. Mario carries Princess Peach 45 meters away from Bowser’s Castle with a force of 5.0 N

Work done= Force*Distance

Work done= 5*45= 225Joules

5. A roller coaster car lifts a group of people 50 m to the top of the roller coaster with a force of 550 N.

Work done= Force*Distance

Work done= 550*50=27500Joules or 27.5kJ

a length 650 cm of thin thread wraps around a cylinder exactly 30 times calculate the circumference and the radius of the cylind
Eduardwww [97]

Answer:

circumference= 65/3  cm = 21.67 cm

radius R = 3.45 cm

Explanation:

To calculate the length of the circumference of the cylinder, we divide 650 cm by 30 (the number of times it wrapped exactly around it)

length of circumference= 65/3  cm = 21.67 cm

now use the formula of the circumference length to find the radius (R):

circumference length = 2 * pi * R

65/3 = 2 * pi * R

R = 65 / (6 pi)

R = 3.45 cm
