Answer:

Shapes and space

Explanation:

3D crafts use shapes and space.

The purpose of space: Distance, area, volume; physical space independent of what occupies it; absolute space.

The purpose of shapes: Positive and negative

Positive shape is the totality of the mass lying between its contours; in three-dimensional work, the visible shape or outer limit of a form changes as the viewer's position is changed. These outer limits are seen as shapes moving back and forth between major contours.

Negative space is empty space defined by a positive shape. Sometimes referred to as occupied and unoccupied space.

A balloon drifts 140 m toward the west in 45 s; then the wind suddenly changes and the balloon flies 90 m toward the east in the

rusak2 [61]

Answer:

Explanation:

Given

1 ) 140 m west in 45 s .

2 ) 90 m east in 25 s .

a )

distance travelled in first 45 s = 140 m

b ) distance travelled in next 25 s = 90 m

c ) Total distance travelled = 140 m + 90 m

= 230 m

d ) average speed in first 45 s

= distance in 45 s 45

= 140 / 45 = 3.11 m /s

e ) average speed in next 25 s

distance in 25 s / 25

= 90 / 25 = 3.6 m /s

f ) average in entire trip

= total distance / total time

= (140 + 90) / ( 25 + 45 )

= 3.28 m /s

g )

displacement in first 45 s = 140 m towards west

h )

displacement in next 25 s = 90 m towards east

i )

total displacement = 140 - 90

= 50 m towards west .

Answer:

About 7.67 m/s.

Explanation:

Mechanical energy is always conserved. Hence:

$\displaystyle \begin{aligned} E_i & = E_f \\ \\ U_i + K_i &= U_f + K_f\end{aligned}$

Where U is potential energy and K is kinetic energy.

Let the bottom of the slide be where potential energy equals zero. As a result, the final potential energy is zero. Additionally, because the child starts from rest, the initial kinetic energy is zero. Thus:

$\displaystyle U_i = K_f$

Substitute and solve for final velocity:
$\displaystyle \begin{aligned} mgh_i &= \frac{1}{2}mv_f^2 \\ \\ 2gh_i &= v^2_f \\ \\ v_f &= \sqrt{2gh_i} \\ \\ & =\sqrt{2(9.8\text{ m/s$^2$})(3.00\text{ m})} \\ \\ & \approx 7.67\text{ m/s} \end{aligned}$

In conclusion, the child's speed at the bottom of the slide is about 7.67 m/s.

Grace [21]

Answer:

Only the 4 th statement is true that is bed 1 and 3 are older than 4.

Explanation:

The 5 beds are numbered from 1 to 5 , 1 being the lowest and 5 being the topmost bed.

We are given 4 statements and we have to find out which all are true.

(a)Bed 4 is older than bed 2

This is wrong because the lower beds are older than beds that are higher.

(b)Bed 3 is older than beds 2 and 4

This is also wrong because the 2 is older than 3

(c)Bed 5 is the oldest

This is wrong because bed 1 is the oldest

(d)Beds 1 and 3 are older than 4

This is true as lower beds are older

Which is not expecting acceleration?

TiliK225 [7]

#1)

1). A point on the outside of a spinning top whose rotational speed is constant.

It will not accelerate as its net speed is ZERO

2). A skydiver whose air resistance is equal to that of her weight.

Since weight is counterbalanced by resistance so here net force is zero so acceleration must be zero here

3). A car on the freeway experiencing a net force of -120 N.

Since there it acts net force F = -120 N so it will accelerate here

4). A submerged beach ball whose buoyant force is eight times the force of gravity on it.

Since buoyant force is more than weight of the ball so it will accelerate upwards

#2)

A non accelerating fra me is always a valid inertial frame

A frictionless spinning merry go round.

(since it is having centripetal acceleration so it is non inertial frame)

A falling rock.

(Since it is falling with acceleration a = 9.8 m/s^2 so it is non inertial)

A hot air balloon moving at 30 degrees east of north with no net force.

(Since net force on hot air balloon is ZERO so it is Inertial Frame)

A space shuttle whose boosters just ignited for takeoff.

(Since space shuttle ignite the boosters so it will accelerate here and hence it is non inertial)

here two forces given as

$F_1 = 4320 N$ towards right

$F_2 = 4380 N$ towards Left

Since left side applied force is more than right side applied force so net force on it will be towards Left and it is given by

$F = 4380 - 4320 = 60 N$

So it is 60 N Left
