240 m/s
- 15 m/s

- 120 m/s
120 m/s

Answer:

Unalanced

Explanation:

The constant motion of a object will not be altered unless another force acts upon it, which will unbalance the object.

Explanation: he moves way to fast

Theodore is 170 centimeters from the finish line when Alvin crosses it.

The total distance is 451 cm, so we can find the time that takes Alvin to crosses the finish line as follows:

[tex] v_{a} = \frac{x}{t} [/tex]   (1)

Where:

[tex] v_{a}[/tex]: is the speed of Alvin = 19.28 cm/s

x: is the total distance = 451 cm

t: is the time that takes Alvin to crosses the finish line =?

By solving equation (1) for t, we have:

[tex]t = \frac{x}{v} = \frac{451 cm}{19.28 cm/s} = 23.4 s[/tex]

Now, after 23.4 seconds have elapsed, Theorode has traveled the following distance ([tex]x_{t}[/tex]):

[tex] x_{t} = v_{t}*t [/tex]

Where:

[tex]v_{t}[/tex]: is the speed of Theodore = 12 cm/s  

[tex] x_{t} = v_{t}*t = 12 cm/s*23.4 s = 281 cm [/tex]

The distance (d) that Theodore needs to travel to cross the finish line is:

[tex]d = x - x_{t} = 451 cm - 281 cm = 170 cm[/tex]

Therefore, Theodore is 170 centimeters from the finish line when Alvin crosses it.

Hey Jinnin! It's Li Aing here. TELL ME WHEN YOU GOT THE ANSWER

Answer:

A

Explanation:

Wattage = E * I

E = 25

I = 5

Wattage = 25 * 5

Wattage = 125

The secondary, in an ideal transformer has the same wattage.

125 = 50 * I           Divide by 50

125/50 = I

I = 2.5

A mechanism is what is responsible for any action or reaction. Machines are based on the idea of transmitting forces through a series of predetermined motions. These related concepts are the basis of dynamic movement.

Explanation:

An object moving in vector quantity can be defined by its magnitude and direction.

If the object has both magnitude and direction and direction or magnitude or both are changing as they are moving, then it is a vector quantity.

proton, neutron, electron (atomic particles

The proton has mass and is positive

The neutron has mass and no charge

The electron has (very small) no mass and negative charge,

Each atomic particle has a different atomic weight.

Answer:

The velocity is decreasing over the time linearly not parabolically. About the mathematical relationship between y-velocity and time here says that there appears to be no outliers, the graph looks to have a strong positive connection, and because the graph is attached, it appears to be more linear.

Answer:

[tex]\boxed {\boxed {\sf 40 \ Newtons}}[/tex]

Explanation:

We are asked to find the force of a wheelbarrow. According to Newton's Second Law of Motion, force is the product of mass and acceleration.

[tex]F= \ m \times a[/tex]

The mass of the wheelbarrow is 20 kilograms. We are not given the acceleration, so we must calculate it using the following formula.

[tex]a= \frac{v_f-v_i}{t}[/tex]

The wheelbarrow starts at rest or 0 meters per second (initial velocity) and accelerates to reach 10 meters per second (final velocity) in 5 seconds (time).

Substitute these values into the formula.

[tex]a= \frac{ 10 \ m/s-0 \ m/s}{5 \ s}[/tex]

Solve the numerator.

[tex]a= \frac{10 \ m/s}{5 \ s}[/tex]

Divide.

[tex]a= 2 \ m/s/s[/tex]

[tex]a= 2 \ m/s^2[/tex]

Now we know the mass and acceleration of the wheelbarrow

Substitute the values into the force formula.

[tex]F= 20 \ kg \times 2 \ m/s^2[/tex]

[tex]F= 40 \ kg*m/s^2[/tex]

Convert the units. 1 kilogram meter per square second is equal to 1 Newton, so our answer of 40 kilogram meters per square second is equal to 40 Newtons.

[tex]F= 40 \ N[/tex]

Answer:

40 N

Explanation:

We know that

F = ma

and

a = (v - u)/t

So,

F = m(v - u)/t

F = 20(10 - 0)/5

F = 20(10/5)

F = 20(2)

F = 40 N

Explanation:

[tex]\text{Acceration is the rate of change of velocity per unit time.}

\text{Suppose the initial velocity is }u,\text{ and the final velocity is }v.

\text{Then the change of speed is }v-u.

\text{If such velocity change takes }t\text{ seconds, the average acceleration is }a.

\text{So we write}[/tex]

[tex]\frac{v-u}{t}=a\implies v=u+at[/tex]

Answer:

64 m

Explanation:

use formula velocity= displacement / time

[tex]\\ \rm\longmapsto Distance=Speed\times Time[/tex]

[tex]\\ \rm\longmapsto Distance=8(8)[/tex]

[tex]\\ \rm\longmapsto Distance=64m[/tex]

There are 60 seconds in 1 minute. So, 3 minutes is the same as 3×60=180 seconds. If you travel 6 m/s (meaning after 1 second, you've run 6 meters), then after 3 minutes (or 180 seconds), you have run 6×180=1080 meters.

Answer: I think the vertical acceleration values are not equal to the theoretical acceleration due to gravity, -9.81 meters/second2 due to the gravity force and maybe the drag due to air resistance.

Explanation: About my earlier prediction about which ball will land first, I can say that my hypothesis was right, but not quite because I calculated the average vertical acceleration, where the time period is t = 0.10 second to t = 1.00 second, the results were different. If the result were maybe right or close to the I would have said that my hypothesis was correct.

A physical change is a change affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds.

Assuming you are supposed to write each conversion in scientific notation:

(2) 1 m = 100 cm, so

(67 cm) × (1/100 m/cm) = 67/100 m = 0.67 m = 6.7 × 10 ⁻¹ m

(3) 1 km = 1,000 m, so

(1.2 km) × (1000 m/km) = 1200 m = 1.2 × 10³ m

(4) 1 m = 1,000 mm = 10³ mm, so

(6.2 × 10 ⁻³ m) × (10³ mm/m) = 6.2 mm

(5) 1 m = 1,000,000,000 nm = 10⁹ nm, so

(4.05 × 10³ nm) × (1/10⁹ m/nm) = 4.05 × 10 ⁻⁶ m

(6) 1 g = 1,000,000 µg = 10⁶ µg, so

(3200 µg) × (1/10⁶ g/µg) = 3200 × 10 ⁻⁶ g = 3.2 × 10 ⁻³ g
