A) You can drop hammer and a feather, both will reach ground at the same time ( it was actually done in Apollo mission)

b) i. Yes, it is similar to weightlessness experienced by astronauts

ii. The phenomenon of "weightlessness" occurs when there is no force of support on your body. When your body is effectively in "free fall" in roller coaster, accelerating downward at the acceleration of gravity, then you are not being supported.
Just like astronauts in space feel no force of support that we on earth feel due to gravity.

Serena is building a bookcase she cuts two pieces of wood from one board one piece is 1 7/8 feey long and another is 3.5 ft long

Vladimir79 [104]

Answer:

$\frac{43}{8}$ feet

Step-by-step explanation:

The total change is the sum of the length of two boards she cut.

First board length is 1 7/8th feet. Let's change to improper fraction:

1 7/8 = 15/8 feet

Second board lengrh is 3.5 feet, or 3 1/2 feet. Let's change to improper fraction:

3 1/2 = 7/2 feet

Let's add the two:

$\frac{15}{8}+\frac{7}{2}\\=\frac{15+28}{8}\\=\frac{43}{8}$

The change in original board is 43/8 feet

A1. 12 i.e option D

A2. 3n-7 i.e option A

A3. -6n+20 i.e option D

A4. -70 i.e option C

Step-by-step explanation:

aₙ = a₁ + (n - 1) × d

aₙ = the nᵗʰ term in the sequence

a₁ = the first term in the sequence

d = the common difference between terms

Using the above formula to solve the first part, we have :

-8 = a₁ + (2-1) × 5

-13 = a₁

a₆ = -13 + (6-1) × 5

a₆ = 12

For the second part, we have :

aₙ = -4 + (n-1)×3

aₙ = -4 + 3n -3

aₙ = 3n-7

For the third part, we have :

a₁=14 ; d=-6

aₙ = 14 + (n-1)×(-6)

aₙ = -6n + 20

For the fourth part, we have :

aₙ = 14 + (15-1)×(-6)

aₙ = -70

Priya bought x grams of flour. Clare bought 3/8 more than that. Select one equation that represent the relationship between the

statuscvo [17]

Answer:

The relationship ship equation:

y = x + 3/8x

Step-by-step explanation:

Let 'x' be the grams of flour Priya bought

Let Clare bought 'y' grams of flour

As Clare bought 3/8 more than that.

y = x + 3/8x

Thus, the relationship ship equation:

y = x + 3/8x
