Answer:

the answer is TIME

Explanation:

This question involves the concepts of acceleration, time, and velocity.

Micah needs "time" to determine acceleration.

Acceleration is defined as the rate of change of velocity. Mathematically,

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

where,

a = acceleration

Δv = change in velocity

t = time interval

Since Micah knows the change in velocity. Therefore, the only thing she needs to know the acceleration is time.

The end of the block closest to the magnet has been magnetized. this  happened to the block of material next to the magnet. Hence option C is correct.

A magnetic field creates a magnetic moment inside ferromagnetic materials like iron when it interacts with the substance. The magnetic moment lines up with the magnetic field outside.

The end of the material block closest to the magnet will encounter the greatest magnetic field and become magnetised in this situation since the magnet is placed near to the material block.

The farthest end of the block would have the smallest magnetic impact since the magnetization diminishes as you get farther from the magnet.

Answer:

The ratio is  [tex]k:d = 1 : 5[/tex]

Explanation:

From the question we are told that

   The first minimum of the single slit pattern falls on the fifth maximum of the double slit pattern.

Generally the condition for constructive interference for as single slit is  

     [tex]ksin(\theta) = n\lambda[/tex]

Here  k is the width of the slit  and n is the order of the fringe and for single slit n =  1 (cause we are considering the first maxima)

Generally the condition for constructive interference for as double slit is    

        [tex]dsin\theta = m\lambda[/tex]

Here  d is the separation between the  slit  and m is the order of the fringe and for double slit  m  =  5  (cause we are considering the first maxima)

=>     [tex]dsin\theta = 5\lambda[/tex]

So

       [tex]\frac{ksin(\theta)}{dsin(\theta)} = \frac{\lambda}{5\lambda}[/tex]

=>    [tex]\frac{k }{d} = \frac{1}{5}[/tex]

So  

      [tex]k:d = 1 : 5[/tex]

Answer:

2 and 0.6 ohms = 1.8A

4ohms = 1.08A

6 ohms = 0.72 ohms

Explanation:

With the help of the given diagram calculate the current through each resistor.​

According to ohms law

E = IRt

E is the electromotive force = 9V

I is the total current in the circuit

Rt is the total equivalent resistance

Get Rt

1/R = (1/4+1/6)  (parallel resistors)

1/R = 3+2/12

1/R = 5/12

R = 12/5

R = 2.4 ohms

Rt = 2 + 0.6 + 2.4

Rt = 5 ohms

Get the total current

I = E/Rt

I = 9/5

I = 1.8A

Since same current flows in a series connected resistors

Current in the 2 and 0.6 ohms resistors will be 1.8A

For the 4 and 6 ohms resistor:

Voltage across them is expressed as:

V = IR

V = 1.8(2.4)

V = 4.32Volts

The current in 4 ohms resistor

I = 4.32/4

I = 1.08A

The current in 6 ohms resistor

I = 4.32/6

I = 0.72A

The approximate mass of the object is. 1. 0.01 kg.

Explanation:

between the magnitude of the gravitational force exerted on Earth by the ... A 60-kg physics student would weigh 1560 N on the surface of planet X.

The projectile has a height h at time t given by

h = (14.0 m/s) t - 1/2 g t ²

where g = 9.80 m/s² is the magnitude of the acceleration due to gravity. Solve for t when h = 0 :

0 = (14.0 m/s) t - 1/2 g t ²

0 = 1/2 t (28.0 m/s - g t )

1/2 t = 0   or   28.0 m/s - g t = 0

The first equation says t = 0, which refers to the moment the gun is first fired, so we ignore that solution. We're left with

28.0 m/s - g t = 0

t = (28.0 m/s) / g

t = (28.0 m/s) / (9.80 m/s²)

t ≈ 2.86 s

Answer:

how long the athlete can sustain the activity

Explanation:

"Endurance" tests your body's ability to carry on a specific activity for a particular period of time. This is often confused with "stamina," which tests the body's ability to do a specific activity without getting exhausted.

An example of an endurance training for the muscles is by doing 5 sets of body weight squats with repetitions, let's say 25. Depending on one's endurance, the repetition may be increased. Another example is by doing 5 sets of lunges with 15 repetitions on each leg (a total of 30 repetitions).

Answer:

i heard my doctor say glutes, so i choose a

Explanation:

Answer:

Option (d) is correct.

Explanation:

Work done is given by :

W = Fd, where F is force and d is displacement

Unit of work done :

The SI unit of force is Newton (N) and that of displacement is meter (m). So, the unit of work done is N-m. It is call Joule. It means that the unit of work done is Joule.

Power is given by rate at which the work is done. It is given by :

P = W/t, W is work done and t is time

Unit of power:

Unit of work is Joule (J) and that of time is second (s). It means that the unit of power is Watt and it is equal to Joule/second

Hence, the correct option is (d) "The unit for work is a joule. The unit for power is a watt, which is a joule per second".

Answer: The unit for work is a joule. The unit for power is a watt, which is a joule per second.

Answer:

The y-axis should be labelled as W in Newtons (kg·m/s²)

Explanation:

The given data is presented here as follows;

Mass (kg)            [tex]{}[/tex]        Newtons (kg·m/s²)

3.2                      [tex]{}[/tex]           31.381

4.6             [tex]{}[/tex]                    45.1111

6.1              [tex]{}[/tex]                    59.821

7.4              [tex]{}[/tex]                    72.569

9                [tex]{}[/tex]                     89.241

10.4              [tex]{}[/tex]                   101.989

10.9              [tex]{}[/tex]                  106.892

From the table, it can be seen that there is a nearly linear relationship between the  amount of Newtons and the  mass, as the slope of the data has a relatively constant slope

Therefore, the data can be said to be a function of Weight in Newtons to the mass in kilograms such that the weight depends on the mass as follows;

W(m) in Newtons = Mass, m in kg × g

Where;

g is the constant of proportionality

Therefore, the y-axis component which is the dependent variable is the function, W(m) = Weight of the body while the x-axis component which is the independent variable is the mass. m

The graph of the data is created with Microsoft Excel give the slope which is the constant of proportionality, g = 9.8379, which is the acceleration due to gravity g ≈ 9.8 m/s²

We therefore label the y-axis as W in Newtons (kg·m/s²)

The true statements about electric motion are:

An electrical device that transforms electrical energy into mechanical energy is an electric motor. The majority of electric motors work by creating force in the form of torque imparted to the motor shaft through the interplay of the magnetic field of the motor and electric current in a wire winding.

Electric generators function with a reversed power flow, transforming mechanical energy into electrical energy, and are mechanically identical to electric motors.

Electric motors can be powered by alternating current (AC) sources like a power grid, inverters, or electrical generators or by direct current (DC) sources like batteries or rectifiers.

Answer:

The total mass of hydrochloric acid and sodium hydroxide will result in the same total mass of sodium chloride and water.

Explanation:

mass and volume are the same thing and has to be the last one.

The total mass of hydrochloric acid and sodium hydroxide will result in the same total mass of sodium chloride and water.

Chemical reactions are the processes by which a substance or substances change chemically to create a new substance or substances with entirely new attributes. Products are completely distinct in nature and identity from reactants.

Chemical reactions never result in the loss or gain of mass. This is due to the fact that chemical reactions do neither produce or consume any atoms.

The reaction of Hydrochloric acid and sodium hydroxide carried out in a typical laboratory setting, matter is neither generated nor destroyed, nor are any elements changed into others. The total mass of the reactants ( NaOH and HCl) and the total mass of the products (NaCl and H₂O) are equal since matter is neither generated nor destroyed during a chemical reaction.

Answer:

the answer is B. the temperature decreases

Explanation:

I got it right.  

The process in which the net heat transfer is equal to zero is known as the adiabatic process. During an adiabatic process in a closed system when the gas expands its temperature decreases.

An adiabatic process is a thermodynamic process in which there is no heat transfer between the system and surroundings. Hence the net heat transfer is equal to zero.

It is given by ΔQ=0.

The temperature in a closed system occurs due to the movement or collision of atoms in the system. As the gas expands the atoms have enough space due to which collision decreases.

Hence during an adiabatic process in a closed system when the gas expands its temperature decreases.
