based on the illustrations, what happens to current in the presence of resistance in the connecting wire?​

Answer:

from spectral lines astronomers Can determine

Answer:

c. changes can occur to certain physical properties

Explanation:

got it right on test

Answer:

the velocity is 4 ms, if it asked for change it be 0 m/s but its asking for velocity so option 4, 4m/s

Explanation:

The correct answer is Option 2: 2 m/s². The acceleration of the object at 8 seconds is 2 m/s². Note that the negative sign indicates that the acceleration is in the opposite direction of the velocity.

To calculate the acceleration of the object at 8 seconds, we need to look at the change in velocity over time (acceleration is the rate of change of velocity).

Given the graph, we can see that at 8 seconds, the velocity of the object is 6 m/s.

Now, let's find the change in velocity between 8 seconds and 10 seconds:

Change in velocity = Final velocity - Initial velocity

Change in velocity = 2 m/s - 6 m/s

Change in velocity = -4 m/s

Next, find the time interval between 8 seconds and 10 seconds:

Time interval = Final time - Initial time

Time interval = 10 s - 8 s

Time interval = 2 seconds

Now, calculate the acceleration:

Acceleration = Change in velocity / Time interval

Acceleration = (-4 m/s) / (2 s)

Acceleration = -2 m/s²

The correct answer is Option 2: 2 m/s². The acceleration of the object at 8 seconds is 2 m/s². Note that the negative sign indicates that the acceleration is in the opposite direction of the velocity.

Answer:

Wavelength.

Explanation:

The measure of energy is straightforwardly corresponding to the photon's electromagnetic recurrence and subsequently, equally, is contrarily relative to the frequency. The higher the photon's recurrence, the higher its energy.

Hope this helps! :D

Inside a laser apparatus, the stimulation and relaxation of electrons in atoms cause many photons with the same wavelength to be continuously emitted.

From the questions given, the main objective is to fill in the gaps and add important information where necessary. The missing information is highlighted in bold and underlined.

Therefore, we can conclude that we've fully understood the concept of emission of photons and wavelength in a laser apparatus.

Explanation:

Answer:

Explanation:

Speed multipliers are useful when an object needs to move a further distance or at a higher speed. Some examples are wheels and axles and third class levers. Machines can be either simple or complex. Simple machines are machines that only use one type of machine, such as a lever or an inclined plane.

Answer:

The size of the frictional force is 577 N.

Explanation:

Frictional forces are exerted every time you have two surfaces sliding across one another. Friction depends on:

There are two types of friction:

Now let's attack the problem:

First, you have to write the data down:

[tex]\bullet \quad m= 63\,kg\\\\\bullet \quad F= 577\,N\\\\\bullet \quad v= 2.4\,m/s[/tex]

If the boy and the sled moves on constant velocity, Newton's First Law Of Motion states that the net force acting on them must be zero:

[tex]F_{net}=0[/tex]

Applying Newton's Second Law Of Motion, we get:

[tex]F-f_d=0[/tex]

which means that:

[tex]F=f_d[/tex]

In other words, the dynamic frictional force equals the force that moves the boy and sled. So we may write:

[tex]\boxed{f_d=577\,N}[/tex]

Conclusion: the size of the (dynamic) frictional force is 577 N.

Velocity:

Velocity is change in displacement with respect to time:

[tex]\frac{\Delta x}{\Delta t}[/tex]

Analysing the units, meters (displacement) and seconds (time) are basic units:

[tex]\frac{m}{s}[/tex]

Therefore the unit of velocity is m/s

Force:

Newton's second law of motion:

[tex]F = ma[/tex]

Kilogram (mass) is a basic unit, and accelerations unit can be found using the equation:

[tex]a=\frac{\Delta v}{\Delta t}[/tex]

Analysing the units:

[tex]\frac{\frac{m}{s}}{s}=\frac{m}{s^2}[/tex]

Therefore, the unit of force is:

[tex]kg\frac{m}{s^2}[/tex]

Pressure:

Pressure is given by the equation:

[tex]P=\frac{F}{S}[/tex] where S is area of effect, F is force

Area for a basic rectangle (geometric shape is arbitrary for dimensional analysis) is found by multiplying two lengths:

[tex][l^2]=m^2[/tex], the unit of area

Dividing the aforementioned unit of force by the unit of area:

[tex]\frac{kg\frac{m}{s^2}}{m^2}=\frac{kg}{ms^2}[/tex], the unit of pressure

Work:

Work is given by the equation:

[tex]W=\vec{F}\cdot \vec{x}[/tex], (dot product may be assumed as normal multiplication for the purposes of unit analysis)

Knowing displacement's (x) unit is m:

[tex][W]=\frac{kgm}{s^2}m=\frac{kgm^2}{s^2}[/tex], the unit of work.

Answer: see example due to variation of factor

Explanation:    w = m x g

Weight= Mass (in kg) x Gravity (9.8m/s)

To get to kg from lbs take your weight divide by 2.2lbs well get you to kg

Example

Let's say a boy weighs 145lbs

145kg/2.2lbs=66kg

Now we use the equation

w=m x g

65kg*9.81m/s=637.65N

Answer:

Vy = V sin theta = 30 * ,574 = 17.2 m/s

t1 = 17.2 / 9.8 = 1.76 sec to reach max height

Max height = 17.2 * 1.76 - 1/2 * 4.9 * 1.76^2 = 15.1 m

H = V t - 1/2 g t^2 = 1.2 * 9.8 * 1.76^2 = 15.1 m

Time to fall from zero speed to ground = rise time = 1.76 sec

Vx = V cos 35 = 24.6 m / sec     horizontal speed

Time in air = 1.76 * 2 = 3.52 sec before returning to ground

S = 24.6 * 3.52 = 86.6 m
