Answer:

i might be wrong here, but i`m pretty sure dimensionless things are infinite, and infinity can not be defined by a single quantity.

for example, since space is constantly expanding, it never has and never will have an actual measurement of any sort.

C. The ladybug's speed and direction are not changing, so she has no acceleration.

In A, B, and D, either speed or direction are changing, and that's acceleration.

Answer:

0.0035 mg

Explanation:

1 mcg = 1e-3 mg

》35 mcg = 35×10^-3 mg

= 0.0035 mg

Answer:

Explanation:

a) 1.00 - 0.12 = 0.88

m = 1200(0.88)^t

b) t = ln(m/1200) / ln(0.88)

c) m = 1200(0.88)^10 = 334.20 g

d) t = ln(10/1200) / ln(0.88) = 37.451... = 37 s

e) t = ln(1/1200) / ln(0.88) = 55.463... = 55 s

Answer:

you stop the ball or bring it to a different direction

Explanation:

i don't know if this helps. i didn't take physics yet. but i hope this helps.

If the force remains constant, then the decrease in the mass of the ball will increase the acceleration of the ball.

Force acting on a body can be defined as the changes in the state of the body of motion or rest. Force can change the speed and the direction of the moving body. The force acting on an object is related to factors which are mass and acceleration of the body.

The mathematical expression from the 2nd law of motion for force can be written as:

F = ma

We can express this equation as:

a ∝ 1/m

Therefore, the acceleration of a moving body is inversely proportional to the mass of that body.

Therefore, if we are applying the constant force on the ball, then this force can produce a greater change in the motion of the ball only if the mass of the ball will be less. Then the acceleration of the moving ball will increase.

Explanation:

Suppose the cheetah is initially positioned at x=0 (m) from the reference, and the gazelle is intially at poisiton x=d (m).

Then, at the worst case, that is when cheetah is running at the maximum case, the position of the gazelle relative to the reference must be larger than that of cheetah.

In equation form,

[tex]0\text{ km}+\frac{100\text{ km}}{1 \text{ hr}}\cdot30\text{ s }\cdot\frac{1\text{ hr}}{3600\text{ s}}\le d \text{ km}+\frac{80\text{ km}}{1 \text{ hr}}\cdot30\text{ s }\cdot\frac{1\text{ hr}}{3600\text{ s}}[/tex]

[tex](100-80)\cdot \frac{30}{3600}\le d[/tex]

[tex]d\ge \frac16\text{ km}=166.66 \text{m}[/tex]

The minimum distance that a gazelle running 80.0 km/hr be ahead of the cheetah to escape is 6.5807km

If a cheetah can maintain its maximum speed of 100 km/hr for 30.0 seconds, the distance covered by the cheetah is expressed as:

Distance  = Speed * time

Given the following:

Distance covered = 100 * 0.00833333

Distance covered = 0.0833 km

If gazelle is running at a speed of 80.0km/hr, the distance of gazelle will be expressed as:

Taking the difference in distance = 6.6664km - 0.0833 km =6.5807km

Hence the minimum distance that a gazelle running 80.0 km/hr be ahead of the cheetah to escape is 6.5807km

Answer:

One must drive [tex]$41 \cdot 8\,miles$[/tex] north and [tex]$68 \cdot 24\,miles$[/tex] south, in order to travel from Atlanta to Macon.

Explanation:

• The distance of an object can be defined as the complete path travelled by an object.

• To find the distance, find its north component.

• For reference see the below graph:

[tex]$$\[\begin{align}& D_{south} = 80\sin \left( {58 \cdot {5^ \circ }} \right) \\& D_{north} = 80\cos \left( {58 \cdot {5^ \circ }} \right) \\\end{align}\]$$Since, $\sin \left( {58 \cdot {5^ \circ }} \right) = \cdot 853$ and $\cos \left( {58 \cdot {5^ \circ }} \right) = \cdot 5224$: therefore,$$\[\begin{align} D_{south} &= 80 \times \left( { \cdot {{853}^ \circ }} \right) \\ \Rightarrow {D_{south}} &= 68 \cdot 24\,miles \\ \end{align}\]$$[/tex]

And

[tex]$$\[\begin{align} D_{north}& = 80 \times \cdot 5224 \\ \Rightarrow D_{north}& = 41 \cdot 8\,miles \\ \end{align}\]$$[/tex]

• Hence, one must drive [tex]$41 \cdot 8\,miles$[/tex] north and [tex]$68 \cdot 24\,miles$[/tex] south, in order to travel from Atlanta to Macon.

Explanation:

All of the above.

Certainly a coaster could be designed without considering any one item of mass, gravity, or rates of direction change, but the success of the ride would be highly suspect.

Ignoring mass (of cars and/or riders) could lead to support members not being strong enough.

Ignoring rates of change of direction could lead to support members not being strong enough or make the forces on the riders uncomfortable.

Ignoring gravity could lead to support members not being strong enough or make the forces on the riders uncomfortable.
