To answer this equation, SUVAT is your best option utilizing and rearranging the known values to solve for the unknown.

here we have the values for

s=895

u=22

v=35

t= the unknown value

in this instant the equation s=0.5 x (u+v)t is the best equation to use

so we sub in the known values

895=0.5 x (22+35)t

rearrange to solve for t

895=28.5t

895/28.5=t

t=31.404 seconds (rounded to 3 decimal places)

Answer:

Resistance of resistor A = 6.0 Ω and resistance of resistor B = 3.0 Ω

Explanation:

When the two resistors are in series, let V₁ = voltage in resistor A and R₁ = resistance of resistor A and V₂ = voltage in resistor B and R₂ = resistance of resistor B.

Given that V₁ + V₂ = 6.0 V and V₁ = 4.0 V,

V₂ = 6.0 V - V₁ = 6.0 V - 4.0 V = 2.0 V

Also, let the current in series be I.

So, V₁ = IR₁ and V₂ = IR₂

I = V₁/R₁ and I = V₂/R₂

equating both expressions, we have

V₁/R₁ = V₂/R₂

4.0 V/R₁ = 2.0 V/R₂

dividing through by 2.0 V, we have

2/R₁ = 1/R₂

taking the reciprocal, we have

R₂ = R₁/2

R₁ = 2R₂

From the parallel connection, let V₁ = voltage in resistor A and R₁ = resistance of resistor A and V₂ = voltage in resistor B and R₂ = resistance of resistor B. Since it is parallel, V₁ = V₂ = V = 6.0 V

Also, V₂ = I₂R₂ where I₂ = current in resistor B = 2.0 A and R₂ = resistance of resistor B

So, R₂ = V₂/I₂

= 6.0 V/2.0 A

= 3.0 Ω

R₁ = 2R₂

= 2(3.0 Ω)

= 6.0 Ω

So, resistance of resistor A = 6.0 Ω and resistance of resistor B = 3.0 Ω

The resistance of A is 6Ω while for B is 3Ω.

Potential difference is the amount of work done in moving a unit charge from one point to another.

When the two resistors are connected in parallel across the 6.0 V battery, the current in B is found to be 2.0 A, hence:

2 * Rb = 6 V

Rb = 3Ω

For the series connection:

I * 3 = (6 - 4)

I = 2/3 A

Hence:

(2/3) * Ra = 4

Ra = 6Ω

The resistance of A is 6Ω while for B is 3Ω.

Explanation:

A change in an object’s motion—such as Xander speeding up on his scooter—is called acceleration. Acceleration occurs whenever an object is acted upon by an unbalanced force. The greater the net force acting on the object, the greater its acceleration will be, but the mass of the object also affects its acceleration. The smaller its mass is, the greater its acceleration for a given amount of force. Newton’s second law of motion summarizes these relationships. According to this law, the acceleration of an object equals the net force acting on it divided by its mass. This can be represented by the equation:

Acceleration=Netforce-Mass or a=F/m

Explanation:

How far will he travel if the rear wheel makes 1200 revolutions on the road?

Since the rear wheel makes one revolution in the distance of a circumference of a circle, C with diameter, d = 16 inches

C = πd²/4

So, the distance, travelled in 1200 revolutions is D = 1200 × C = 1200πd²/4

Substituting d = 16 into D, we have

D = 1200πd²/4

D = 1200π(16)²/4

D = 76800π

D = 241,274.32 inches

Explanation:

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

Momentum = mass * velocity

The law of conservation of momentum states that the total linear momentum of any closed system would always remain constant with respect to time.

Hence, the law of conservation of momentum states that, if left alone, the total momentum of two interacting objects that make up a system remains the same.

This ultimately implies that, if two interacting objects exert forces only on each other, their total momentum will remain the same i.e it is conserved.

Explanation:

A diode, which allows current to flow in one direction only, consists of two types of semiconductors joined together.

A semiconductor can be defined as a crystalline solid substance that has its conductivity lying between that of a metal and an insulator, due to the effects of temperature or an addition of an impurity. Semiconductors are classified into two main categories;

1. Extrinsic semiconductor.

2. Intrinsic semiconductor.

An intrinsic semiconductor is a crystalline solid substance that is in its purest form and having no impurities added to it. Examples of intrinsic semiconductor are Germanium and Silicon.

In an intrinsic semiconductor, the number of free electrons is equal to the number of holes. Also, in an intrinsic semiconductor the number of holes and free electrons is directly proportional to the temperature; as the temperature increases, the number of holes and free electrons increases and vice-versa.

In an intrinsic semiconductor, each free electrons (valence electrons) produces a covalent bond.

Answer:

density; thermal

Explanation:

Convection currents occur in fluids because of temperature and density differences. Convection currents transfer thermal energy throughout a fluid.

When a fluid is heated, the molecules closest to the heat source gets heated first and their temperature is raised. The rise in temperature lowers their density and as such, they move to the upper portion of the fluid to be replaced by yet-to-be-heated molecules at the upper portion.

When the replacement molecules also get heated, the same process occurs and a to-and-from rotational movement of molecules, also known as convection current, is created within the fluid. The to and from movement, thus, transfer thermal energy within the fluid until all the molecules within the fluid are at the same temperature.

Answer:

96.3%

Explanation:

Efficiency = Work input/Work output * 100%

Work done = Force * distance\

Work done by the engine is the work output = 700 * 0.55

Work output = 423.5Nm

Work done by you is the work input = 35.7*11.43

Work input = 408.051Nm

Efficiency = 408.051/423.5 * 100

Efficiency = 0.963 * 100

Efficiency = 96.3%

Hence the efficiency of the pulley system is 96.3%

Answer:

0 becouse it will still before falling

Explanation:

Answer & Explanation:

The acceleration due to gravity is about 10 m/s^2.

That means a the speed of a falling object will increase by 10 m/s every second that it falls.

We know that the lamp hits the ground at 15 m/s.

That means the lamp has been falling for

[tex]\frac{15 m/s}{10 m/s^{2} } = 1.5 s[/tex]

Now we use the formula  [tex]h = \frac{1}{2} gt^{2}[/tex]  to calculate the height, where

h is the height

g is the acceleration due to gravity and

t is the time taken to fall a height of h.

h = 1/2 x 10 x 1.5^2 = 11.25 m

Answer:

[tex]R = 1.5* 10^{-10}m[/tex]

Explanation:

Given

[tex]r = 2.5 * 10^{-11}m[/tex] -- radius of hydrogen atom

See attachment

Required

Determine the radius of magnesium atom (R)

From the attachment, the ratio of a hydrogen atom to a magnesium atom is:

[tex]Ratio = 6mm : 36mm[/tex]

Simplify

[tex]Ratio =1 : 6[/tex]

Represent the radius as ratio:

[tex]Ratio = r : R[/tex]

Substitute [tex]r = 2.5 * 10^{-11}m[/tex]

[tex]Ratio = 2.5 * 10^{-11}m : R[/tex]

Equate both ratios

[tex]2.5 * 10^{-11}m : R = 1 : 6[/tex]

Express as fraction

[tex]\frac{2.5 * 10^{-11}m}{R} = \frac{1}{6}[/tex]

Cross Multiply

[tex]R * 1 = 2.5 * 10^{-11}m * 6[/tex]

[tex]R * 1 = 2.5 * 6* 10^{-11}m[/tex]

[tex]R * 1 = 15* 10^{-11}m[/tex]

[tex]R = 15* 10^{-11}m[/tex]

[tex]R = 1.5*10* 10^{-11}m[/tex]

[tex]R = 1.5* 10^{1-11}m[/tex]

[tex]R = 1.5* 10^{-10}m[/tex]

Hence, the radius of the magnesium atom is: [tex]1.5* 10^{-10}m[/tex]

Explanation:

Given that,

Mass of a gas cylinder, m = 90 kg

The diameter of the cylinder, d = 1.1 m

Radius, r = 0.55 m

We need to find the ground pressure. The pressure is equal to force per unit area. So,

[tex]P=\dfrac{F}{A}\\\\P=\dfrac{mg}{\pi r^2}\ (A\ is\ area\ of\ base)\\\\P=\dfrac{90\times 9.8}{\pi \times (0.55)^2}\\\\P=928.09\ Pa[/tex]

So, the ground pressure is 928.09 Pa.

When the string moves, it creates a very small change in the distance to the next point, th

Explanation:

When the string moves, it creates a very small change in the distance to the next point, this generates a restoring force that tends to push the string back, this small disturbance propagates along the string and is what creates the pulse.

This is similar to what happens when a spring is stretched and a restoring force is generated shaved by the law of shortening.

            F = k Dx

Answer:

As the first particle travels upward, it pulls on the next particle, which follows the first particle upward. Then next in line is pulled up in turn, and so on. The motion of each particle follows the one before it, either up or down, with a slight lag in time. This succession of particles moving up or down travels along the string as a wave. Eventually, it pulls every particle along the string up and down in series.

Car A has twice the energy of car B.

Explanation:

The kinetic energy of an object is given by :

[tex]K=\dfrac{1}{2}mv^2[/tex]

Where

m is the mass

v is the speed of the object

Car A has twice the mass of Car B. Both travel at the same speed i.e.

[tex]m_A=2m_B[/tex]

So,

[tex]\dfrac{K_A}{K_B}=\dfrac{(1/2)m_Av^2}{(1/2)m_Bv^2}\\\\=\dfrac{2m_B}{m_B}\\\\\dfrac{K_A}{K_B}=2\\\\K_A=2\times K_B[/tex]

So, the kinetic energy of car A is twice of the kinetic energy of car B.
