To divide 20 miles by 5 hours, what conversion should be made to make the calculation correct?

Explanation

20 miles refer to the distance travelled

5 hours refers to the time taken

So dividing distance by time would give us speed

Since both are different physicals quantity so their units need not be same.

Conclusion

The correct statement is

Divide the two numbers as given--units do not have to be the same when dividing.

1. The acceleration of the cyclist is 0.42 m/s²

2. The total distance travelled by the cyclist is 2437.5 m

1. How to determine the acceleration    

We can obtain the acceleration of theration of the cyclist as follow:

a = (v – u) / t

a = (25 – 12.5) / 30

a = 12.5 / 30

a = 0.42 m/s²

Thus, the acceleration is 0.42 m/s²

2. How to determine the total distance

We'll begin by obtaining the distance travelled in the first 30 s. This can be obtained as follow:

s = (u + v)t / 2

s = [(12.5 + 25) × 30] / 2

s = [37.5 × 30] / 2

s = 1125 / 2

s = 562.5 m

Next, we shall determine the distance in the next 60 second.

s = vt

s = 25 × 60

s = 1500 m

Next, we shall determine the distance in the last 15 seconds.

s = (u + v)t / 2

s = [(25 + 0) × 15] / 2

s = [25 × 30] / 2

s = 750 / 2

s = 375 m

Finally, we shall determine the total distance travelled.

Total distance = 562.5 + 1500 + 375

Total distance = 2437.5 m

Thus, the total distance travelled is 2437.5 m

You and your friends are revolving at the same speed. As a result, your friend and you both have the same angular velocity.

Now that we have the formula for linear velocity—V = omega—we can move on to the following section and draw the conclusion that if the relationship between and grows, so will we.

From here, we may also infer that the radius is larger in this instance because you are close to the right edge. Since you and your friend have different linear velocities and you have the higher linear velocity. If you've ever actually been on a merry-go-round, you already know that being on the edge is considerably more enjoyable rotation than being in the centre.

The effective resistance of two equal resistors connected in series is twice that of a single resistor, reducing the amount of current flowing in the circuit.

The effective resistance of two resistors connected in series is the sum of their individual resistances. Given two resistors with resistance values R1 and R2, the effective resistance, Rx, is given by:

Rₓ = R₁ + R₂        

If the resistance values of these resistors are equal, say R, then equation 1 becomes:

Rₓ = R + R

Rₓ = 2R

That is, their effective resistance is twice as strong as their individual resistances. In other words, when two equal resistors are connected in series, their effective resistance is twice the resistance of each resistor.

Ohm's law states that voltage (V) is the product of current (I) and resistance (R) i.e.

V = IR

I = V/R

We can conclude that as resistance decreases, current increases and vice versa.

As a result, connecting the two equal resistors described above in series reduces the amount of current flowing compared to having just a single resistor.

The average intensity of the wave 1 is 9 times the average intensity of the wave 2.

When a electromagnetic wave moves, it carries electric as well as magnetic energy in itself.

The energy of the EM waves is by the equal contribution of both the waves.

It is provided, that wave 1 has electric field E that is three times the maximum electric energy E' of the wave 2.

So, we can say,

E/E' = 3

We know,

The intensity of the wave is given by,

I = 1/2eE²c

Where,

I is the intensity of the wave,

e is a permittivity of free space,

E is the strength of the wave,

c is the speed of light

Now, intensity of the wave 1,

I1 = 1/2eE1²c

For wave 2,

I2 = 1/2eE²c

Now, dividing both the intensity,

I1/I2 = E1²/E2²

We know,

E/E' = 3

So,

I1/I2 = 9

I1 = 9I2

Simply connect the battery's positive terminal to one of the electrical contacts on your light bulb and its negative terminal to the other.

Many lightbulbs have one electrical contact with screw threads, while the other contact is typically a circular dot on the base end. Other bulbs will protrude metal prongs. Soldering wires onto batteries and lights is infamously difficult to achieve adequate electrical contact. In flashlights, the spring contacts function significantly better (but even they are troublesome from time to time).

It's crucial to choose a bulb that works with the amount of power your battery can supply. The bulb's filament won't grow hot enough to visibly glow if the battery voltage is too low, resulting in a tiny current flowing through the bulb. If the battery voltage is too high, the filament will burn out due to the excessive current flow.

The filament will become overheated and evaporate if the battery has a voltage that is too high.

Standard bulbs require a voltage of about 120 V to operate, which is an uncommon range for batteries. Ordinary flashlight bulbs require roughly 3V to operate, which is simple to acquire by connecting two batteries in series. Typically, automotive bulbs are made to operate with 12V, which is the output of an automobile battery or eight conventional battery cells connected in series.

The Vertical position of the rope at 5 seconds is 5.7cm and the times at which its position is +2cm is 0.311 seconds and 3.66 seconds.

The position of a rope can be described by a simple sin function,

x = Asin(2πt/T)

where,

x is the position at time t,

t is the time,

T is the total time period of oscillation,

A is the amplitude,

a) The vertical position at t = 5 seconds can be found by using the above formula by putting the values,

Amplitude is 5cm.

Time period is 8 seconds,

So, putting values,

x = Asin(2πt/T)

x = 8sin(2π5/8)

x = 8sin(5π/4)

x =8(-0.70)
x = 5.7 cm.

b) Now, putting x = 2cm and solving,

2 = 8sin(2πt/8)

1/4 = sin(πt/4)

sin(Ф) = 1/4

when Ф = 14° and 165° (approximately)

Converting these into radians,

1 degree = π/180

14° = 14π/180 radians

165° = 165π/180 radians

Putting Ф = 14π/180

14π/180 = πt/4

t = 0.311 seconds

Now, putting Ф = 165π/180,

165π/180 = πt/4

t = 3.66 seconds.

As a vector measurement of the rate and direction of motion, velocity is defined. Velocity can be defined as the rate of movement in one direction. A rocket launching into space and a car going north on a busy freeway can both be quantified using velocity.

The velocity vector's scalar (absolute value) magnitude corresponds to the motion's speed, as you would have anticipated. Velocity is the first derivative of position with respect to time in calculus. A straightforward formula that incorporates rate, distance, and time can be used to compute velocity. Even though they are different metrics, speed, velocity, and acceleration are all related to one another.

The collision is perfectly elastic, so the speed of the 0.484- kg ball after the collision will be 5.66 meter per second.

We have a ball; the mask's mass should be 0.440 kg. Additionally, it is moving at a speed of 3.80 middle birth seconds. So it grapples with another ball that has a mask head-on. MB 20.220 Kg. B = 0 because it was at rest, so we will get B. They are now claiming that this collision was flawlessly elastic. Therefore, following a collision, we must determine the speed and direction of each ball. Therefore, we can now write V A minus we B is equal to minus V A dash minus V B using the relationship between the velocities. Where we are, dash, then B B dash R.

The speeds of ball and ball B following impact. As VB is already zero, the formula for V B dash will now be V A + V a dash. Therefore, we will now use the law of conservation of momentum. Therefore, we can write MAN for elastic collisions in accordance with the law of conservation of momentum. Two M A N is equivalent to two V A plus MB divided by VB. Do be two VB dashes plus an MB. V B was now equal to 0. The result of this expression will be zero. As a result, once we get em A there, M A V A dash plus M B will end. And we'll just add VA plus VA dash for the value of the vb dash.

Now that we have all the values, we can simply enter them. For example, a dash will represent MA- MB, which is 0.440 -0.22. subtract 0.440 add 0.22 multiplied by the first ball's velocity, which is 3.80. Hence We discover the first ball's velocity value. After elastic collision, two is equal. Be a dash that is 266 metres long and lasts one second in the east. Therefore, we must now determine the value of the vb dash. As a result, vb dash equals B plus we're dash. Therefore, we have both values. In light of this, we determine that B B dash equals two 3.80 + 1.266. We now have the speed for B B dash, which is 5.66 metres per second in the same direction as before.
