A particle P, starting from rest at A, moves in a straight line ABCD. It accelerates uniformly at 5ms-2 from A to B. From B to C

Radda [10]

First, we find the time spent accelerating:
s = ut + 1/2 at²; u = 0
10 = 1/2 5t²
t = 2 seconds
Velocity at point B:
v = u + at; u = 0, a = 5 m/s², t = 2 s
v = (5)(2) = 10 m/s

Now, the same velocity is at C so we find the time decelerating to 0 in CD
v = u + at, v = 0, u = 10 m/s, a = -4 m/s²
0 = 10 - 4t
t = 2.5 seconds
Total time = time(AB) + time(BC) + time(CD)
20 = 2 + time(BC) + 2.5
time(BC) = 15.5 seconds

Distance = velocity x time
BC = 10 x 15.5
= 155 m

A model of space shuttle Apollo Saturn V is created width a scale of 1: 144 if the actual space shuttle has a width of 62.4 feet

ollegr [7]

The width of model is 5.2 inches

<em><u>Solution:</u></em>

Given that, model of space shuttle Apollo Saturn V is created width a scale of 1 : 144

The actual space shuttle has a width of 62.4 feet

Convert 62.4 feet to inches

1 feet = 12 inches

62.4 feet = 12 x 62.4 inches = 748.8 inches

Actual width = 748.8 inches

To find: Width of model in inches

From given,

Scale width : Actual width = 1 : 144

Let "x" be the scaled width

Then we can say,

Scale width : Actual width = 1 : 144

x : 748.8 = 1 : 144

In fractions,

$\frac{x}{748.8} = \frac{1}{144}\\\\x = \frac{748.8}{144}\\\\x = 5.2$

Thus the width of model is 5.2 inches

Eye Color Each of two parents has the genotype brown>blue, which consists of the pair of alleles that determine eye color, an

dalvyx [7]

Answer:

A) Brown-Brown ,Brown-Blue, Blue-Brown, Blue-Blue B) 1/4 =0,25 C)3/4=0,75

Step-by-step explanation:

Lets mother's "BROWN" is "BROWN-M",

mother's "BLUE" is " BLUE-M"

Lets father's "BROWN" is "BROWN-F" and

father's "BLUE " is "BLUE-F"

The kid can have the genotype as follows (list of possible outcomes) :

1. BROWN-M>BROWN-F ( received BROWN as from mother as from father)

2. BROWN-M>BLUE-F ( Received BROWN from mother and BLUE from father)

3. BLUE-M>BROWN-F ( Received BLUE from mother and Brown from father)

4. BLUE-M>BLUE-F ( Received BLUE as from mother as from father)

b) As we can see in a) only 1 outcome from 4 is BLUE-BLUE. So the probability of BLUE-BLUE genotype is

P(BLUE>BLUE)=1/4=0.25

c) As we know that if the child has at least one brown allele, that color will dominate and the eyes will be brown.

It means that outcomes BROWN-BROWN, BROWN-BLUE and BLUE-BROWN determine brown color of eye. So the number of these outcomes is 3. Total amount of outcomes is 4.

So probability that eyes are brown is P(Brown eyes)=3/4 =0.75
