butter is needed to make 12 batches of cookies? Dimensional analysis

Answer:Boiling

Explanation: If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapour as it gets warmer.

Instability of the surface, external vibrations, and electromagnetic interference can cause the mass displayed on a digital scale to fluctuate.

Instability of the surface, external vibrations, and electromagnetic interference are factors that can impact the accuracy of a digital scale's readings. If the surface the scale is placed on is not stable, the reading may fluctuate even if the weight of the object being measured does not change.

Similarly, vibrations from external sources such as foot traffic or machinery can cause the scale to vibrate, leading to fluctuating readings. Electromagnetic interference from electronic devices such as cell phones or computers can also impact the accuracy of the scale's readings.

Answer:

E = 3456 J

Explanation:

The electrical energy expended in a resistor can be easily calculated by using the following formula:

\(E = Pt\)

where,

E = Energy Expended = ?

I = current through 5 ohm resistor = 2.4 A

R = Resistance = 5 ohms

P = Electrical Power = VI

Since,

V = IR (Ohm's Law)

Therefore,

P = (IR)(I) = I²R = (2.4 A)²(5 ohms) = 28.8 Watt

t = time taken = (2 min)(60 s/1 min) = 120 s

Therefore,

E = (28.8 Watt)(120 s)

Muscles are protected from damage caused by excessive contraction by D. Golgi tendon organs

Muscles are protected from damage caused by excessive contraction by Golgi tendon organs. Golgi tendon organs are sensory receptors located at the junction between muscles and tendons. They detect changes in tension or force within the muscle-tendon complex.

When excessive force is applied to a muscle during contraction, the Golgi tendon organs are activated. They send inhibitory signals to the muscle, causing it to relax and prevent further contraction. This protective mechanism helps prevent muscle damage and maintain the integrity of the musculoskeletal system. Options A, B, C, and E are not directly involved in protecting muscles from excessive contraction. Gamma efferents are motor neurons that innervate muscle spindles, which are involved in muscle stretch reflexes. Hence the correct option is D.

Spindle afferents transmit sensory information from muscle spindles. Extrafusal motor pools are groups of motor neurons that innervate extrafusal muscle fibers. Synergistic muscles are muscles that work together to produce a coordinated movement.

The final volume of the gas, is 0.065 m³.

The work done by the gas is 2.629 kJ.

The final volume of the gas, is calculated as follows;

PV = nRT

where;

P₁V₁ = P₂V₂

V₁ = (nRT)/P₁

V₁ = (2 mol x 8.31451 J/K·mol x 367 K) / (0.6 atm x 101325 Pa/atm)

V₁ = 0.1 m³

The final volume of the gas is calculated as;

Explanation:

The magnitude of the electric field if the electron just misses the top plate is 364 N/C.

Time taken by electron is given as

t = x / Vo

t = distance / speed

where, Vo = velocity = 1.6 × 10⁶ m/s

x = distance = 2 cm = 0.02 m

t = 0.02 / 1.6 × 10⁶ m/s = 1.25 × 10⁻⁸ s

Answer:

Explanation:

Answer:

Explanation:

Answer:

The ball will be travelling downward with a speed of 9.8 m/s.

Explanation:

The ball will be travelling downward with a speed of 9.8 m/s.

Explanation:

The acceleration of the ball will be a constant  

9.8 m s 2

(downward), regardless of whether the ball is travelling upward or downward.

The equation that makes this calculation simplest is

v f = v i − g ( Δ t )  

where the negative sign has been used to account for the opposite directions of  v i  and  g . After 3 seconds, v f = 19.6 − ( 9.8 ) ( 3 ) = 19.6 − 29.4 = − 9.8 m s

The negative result tells us that the ball is on its way downward by this time (consistent with our choice of a negative value for the downward acceleration of gravity).

Complete question :

Tony drives his car . He drives the first 13 miles in 13 minutes. He then drives at an average speed of 68mph for 1 hour 24 minutes . Find how much petrol he uses using the information in the table.

Requires table to answer question is attached below

Answer:

2.64 gallons

Explanation:

Given that:

First 13 miles takes 13 minutes

Average rate = 13 miles / 13 minutes = 1mile/minute ; Average rate per hour = (1 mile /minute * 60) = 60 miles /hour

If average speed = 65mph or less ; 50 miles per gallon (it uses 1 gallon for 50 miles)

Hence, since first phase rate is 60 mph,; then miles per gallon is 50 miles

Therefore,gallon of petrol used for 13 miles will be :

13 miles / 50 mpg = 0.26 gallons

2nd phase:

Average rate of 68 mph for 1 hour 24 minutes (1.4 hours)

Here, miles per gallon = 40 (that is; 40 miles for 1 gallon).

Total distance covered = 68 * 1.4 = 95.2 miles

Petrol used = 95.2 miles / 40 mpg = 2.38 gallons

Hence,

Total petrol used : (0.26 + 2.38) = 2.64 gallons

3. 10 m/s

hope you find help

now the reson for this will be

let's look in 1st part

we will use v=u+at

where v will be zero at highest pont u is 10m/s

we can take g as 10 or 9.8

so

0=10-10t

so it becomes

-10/-10=t

so 1 sec will be the answer

in 2nd part same time will be taken to come back so total time will be 2 sec

3rd part we can use v=u+at

where we have to find v, u=10 g=-10 and t=2 sec

now v=10-20 so v= -10 m/s

since in question it's asking abaout speed and as speed is a scaler quantity so answer will be mode of -10 so it becomes 10m/s

Answer:

The intensity of light can change with the time of the day, season, geographic location, distance from the equator, and weather. It gradually increases from sunrise to the middle of the day and then gradually decreases toward sunset; it is high during summer, moderate in spring and fall, and low during winter time.

Explanation:

translational movement with the tilt of the earth's axis we can explain the change in intensity that an area receives determined with the weather station.

The intensity of the radiation is defined by the relationship between the power on the irradiated surface

        I = P / A

where I is the intensity, P is the power emitted by the sun and A is the area.

The intensity of the radiation that reaches it is around 1400 W / m² in the upper part of the Earth's atmosphere, this amount varies slightly when the planet passes from its furthest point from the sun to its closest point, that is, perihelion to aphelion.

The most important variation of this intensity is due to the fact that it has its axis inclined and the normal to the area changes in relation to the incident radiation during the translational movement around the sun.

In the summer the axis of the earth is inclined towards the sun, so the rays fall more perpendicularly, therefore their absorption over the area is maximum and the temperature rises.

In winter, the earth's axis is tilted away from the sun, so the rays they carry are distributed over a larger surface area and therefore less energy is absorbed per unit area and the temperature decreases.

In the spring and autumn seasons, the Earth's axis is almost vertical, so the absorption is intermediate and the temperature of the Earth is between the two maximums.

Using an analysis of the translational movement with the inclination of the earth's axis, we can explain the change in intensity received by an area determined with the weather station.

After 102.7 oscillations, the amplitude decreases to one-fourth of the initial value.

Amplitude is the separation between the wave's resting position and its maximum displacement. Frequency is the number of waves that cross a particular point in a second. Period is the length of time it takes for a wave cycle to complete.

λ = 1/51⋅0.20slog(1/2)

λ = −0.68⁻¹s

Using the previous finding, we can calculate the amplitude as a function of time to determine how long it will take before it reaches one-fourth of its initial value.

1/4=Aeλt

Solving for the time,

t = 1/λlog(1/4)

t = 20.4s

Comparing this result with the period,

t = 102.7T.

The amplitude is the largest displacement or distance that a point on a vibrating body or wave can move away from its equilibrium location. It is equal to dividing by two the length of the vibration path. The distance between a wave's resting position and its greatest displacement is known as amplitude. The frequency is the number of waves that pass through a specific location in a second. Period: the time required to complete a wave cycle to complete.
