When a front wheel drops off the roadway you should?

Answers

braking and returning suddenly to the roadway

When a front wheel drops off the roadway, stay calm, maintain a firm grip on the steering wheel, slow down gradually, and carefully steer back onto the road while checking for traffic.

When a front wheel drops off the roadway while you are driving, there are several steps you should follow to safely regain control:

Stay calm: Avoid any sudden movements or panicking, which can worsen the situation.

Hold the steering wheel: Keep a firm grip on the steering wheel to maintain control of the vehicle.

Decelerate gradually: Slowly lift your foot off the accelerator to decrease speed, but do not brake suddenly as this can cause further loss of control.

Slowly steer back: Gradually steer the vehicle back onto the roadway once you have slowed down sufficiently.

Check for traffic: Always ensure it is safe to merge back onto the road by checking for other vehicles.

By following these steps, you can safely recover from your front wheel dropping off the roadway and minimize the risk of an accident.

A 100 kg bag of sand has a weight on 100 N. When dropped its acceleration is what?

Answers

100N describes the weight of the sandbag, while 100kg is the mass of the sandbag.

To calculate acceleration, divide your weight by the mass, thus the accleration is:

[tex]100N/100kg = 1(m/s^2)[/tex]

Answer:

Gravity.

Explanation:

If you are holding the bag of sand, the only acceleration in the system is gravity, because is a vertical movement. So, [tex]a = 9.81 \frac{m}{s^{2} }[/tex]

We are assuming that is vertical movement because is say ''dropped'', which is a term used in Free-fall models, where acceleration is constant.

T = (2π) sqrt(m/k)
T = (2π) sqrt(1.5/(1.8x 10^2)) = .5732s

F = 1/T
F = 1÷.5732=1.744Hz

Part A: The time period of the mass-spring system is 0.573 seconds.

Part B: The frequency of the vibration of the mass-spring system is 1.75 Hz.

Time Period and Frequency

Given that the mass of the spring is 1.5 kg and the spring constant is 1.8 × 10^2 n/m.

Part A

The period of the mass-spring system is given by the formula.

[tex]T=2\pi\sqrt{\dfrac {m}{k}}[/tex]

Where m is mass and k is spring constant.

Substituting the values in the above equation, we get the time period.

[tex]T = 2 \times 3.14 \times \sqrt{\dfrac {1.5}{ 1.8 \times 10^2}}[/tex]

[tex]T = 0.573 \;\rm s[/tex]

Hence the time period of the mass-spring system is 0.573 seconds.

Part B

The frequency of the vibration is given below.

[tex]f = \dfrac {1}{T}[/tex]

[tex]f = \dfrac {1}{0.573}[/tex]

[tex]f = 1.75 \;\rm Hz[/tex]

Hence the frequency of the vibration of the mass-spring system is 1.75 Hz.

Answers

Cobalt-60 is undergoing a radioactivity decay.

The formula of the decay is n=N(1/2)∧(T/t).
Where N ⇒ original mass of cobalt
           n ⇒ remaining mass of cobalt after 3 years
          T ⇒ decaying period
           t ⇒ half-life of cobalt.

So,
0.675 = 1 × 0.5∧(3/t)
log 0.675 = log 0.5∧(3/t)
3/t = log 0.675 ÷log 0.5
 3/t= 0.567

t = 3÷0.567
  = 5.290626524

the half-life of Cobalt-60 is 5.29 years.

Answers

For those of you taking the course on Edge, the right answer is D.

Answer: D) Substance W will transfer thermal energy to substance X through conduction if they are mixed.

Explanation:  Thermal energy is the energy possessed by an object by virtue of its temperature. It is transferred from a hotter object to a colder object till both the bodies attain the same temperature.

Radiation occurs when  thermal energy is transferred by electromagnetic waves. Conduction occurs when thermal energy is transferred when two objects are in direct contact.

Thus Substance W at a temperature of [tex]40^0C[/tex] will transfer thermal energy to substance X at a temperature of [tex]37^0C[/tex] through conduction if they are mixed as they are in direct contact.

a roller coaster slows as it travels up a hill
a) speed
b) velocity
c) acceleration

Answers

think the answer should be C
Final answer:

As the roller coaster ascends the hill, it experiences a decrease in speed which affects its velocity, leading to what we describe as negative acceleration or deceleration.

Explanation:

When a roller coaster is traveling up a hill, it begins to slow down due to the force of gravity opposing its motion. This is a scenario of negative acceleration or deceleration.

Speed refers to how fast an object is moving without concerning the direction. In this case, the speed of the roller coaster decreases as it climbs the hill.

Velocity includes both the speed and direction of an object's motion. Here, the velocity also decreases as the speed decreases and the direction is upwards.

Acceleration refers to the rate of change of velocity. When the roller coaster slows down while moving up, it is undergoing negative acceleration or deceleration.

What is the wavelength (angstroms) of a photon that has an energy of 4.38 x 10-18 j?

Answers

The relationship between energy and frequency of a photon is given by
[tex]E=hf[/tex]
where E is the energy, h is the Planck constant and f is the photon frequency. By re-arranging the equation and using the photon energy, we can calculate its frequency:
[tex]f= \frac{E}{h}= \frac{4.38 \cdot 10^{-18} J}{6.6 \cdot 10^{-34}Js}=6.64 \cdot 10^{15} Hz [/tex]

Then we know that the photon travels at speed of light, c, so we can find its wavelength by using
[tex]\lambda= \frac{c}{f}= \frac{3 \cdot 10^8 m/s}{6.64 \cdot 10^{15}Hz}=4.52 \cdot 10^{-8} m [/tex]

And since 1 A (angstrom) corresponds to [tex]10^{-15} m[/tex], the wavelength expressed in angstroms is
[tex]\lambda= \frac{ 4.52 \cdot 10^{-8} m}{10^{-15} m/A} = 4.52 \cdot 10^7 A [/tex]

Answer: The relationship between energy and frequency of a photon is given by E = h*f.

E is the energy, h is planck constant and f is the frequency and f= c/λ.

But i want wavelength, so i write this equation as E= h*c/λ.

now

c=3.8[tex]*10^{8}[/tex]

E =4.38*[tex]10^{-18} [/tex]  [tex]\frac{m^{2}*kg }{s^{2} }[/tex]

where i replaced joules for  [tex]\frac{m^{2}*kg }{s^{2} }[/tex]

h = 6.62607004 *[tex]10^{-34}[/tex][tex]\frac{m^{2}*kg }{s }[/tex]

then λ = h*c/E =  [tex]\frac{6.62607004 *10^{-34}*3.8*10^{8}m/s}{4.38*10^{-18} \frac{m^{2}*kg }{s^{2} }}[/tex] = 5.7*[tex]10^{-8}[/tex]  m

But you want the solution in angstroms, so 1  meter is [tex]10^{10}[/tex] angstroms

lubricating a machine will make it more efficient and it will reduce the friction between the parts meaning that less energy will be transferred and dissipated into the surroundings as heat.
the in put and out put force may increase as it's easier for the machine to work due to less friction

By lubricating its components, a machine can operate more effectively and send less energy to the environment as heat by reducing friction between its parts.

Due to the machine's simplicity of use and less friction, the input and output forces might both increase.

What is lubrication?

To reduce wear and tear and friction in a contact between two surfaces, lubrication is a procedure or technique that uses a lubricant. The area of tribology includes the study of lubrication as a discipline.

Solid body interactions are decreased through the design of lubrication mechanisms, such as fluid-lubricated systems, which carry the given load either entirely or partially by hydrodynamic or hydrostatic pressure (and consequently friction and wear).

Eclipses are of two types: Solar and Lunar eclipse. A solar eclipse occurs when the moon enters between the sun and the earth, which its shadow on the earth's surface.

A lunar eclipse occurs when the earth is moved between the sun and the moon and the Earth leaves its shadow on the moon. The tides form in seas because of the gravitational force of the moon.

The gravity of the moon makes the tides or waves in the seas or oceans. The full moon has more gravitation force and hence, larger tides are formed. The largest tides are also formed by solar and lunar eclipses.

When the sun is aligned with the moon during the eclipse, the sun is also pulling in the same direction resulting in the largest tides. The gravitational pull of the sun and moon increases the tides in ocean surfaces on Earth.

A girl throws a rock horizontally, with a velocity of 10 m/s, from a bridge. it falls 20 m to the water below. how far does the rock travel horizontally before striking the water, assuming negligible air resistance?

Answers

Before you begin, you need to first figure out what your problem gives you and what you need to look for.
Given:
vix=10m/s
dy= 20m

What you are looking for is horizontal distance or dx.

The formula for vertical distance is:
[tex]dx=vi_{x}t[/tex]

Where:
dx= horizontal distance
vix= initial horizontal velocity
t=time

But when you look at your problem, you do not have time. Now for time, you need to use the formula:

[tex]t= \sqrt{ \frac{2dy}{g} } [/tex]

g in this equation is a constant. It is the acceleration due to gravity which has the value of 9.8m/s^2.

Now we first need to get time:
[tex]t= \sqrt{ \frac{2dy}{g} } [/tex]
[tex]t= \sqrt{ \frac{2(20m}{9.8m/s^{2}} } [/tex]
[tex]t= \sqrt{ 4.08163265} [/tex]
[tex]t=2.02s [/tex]


Now that you have time, all you need to do is insert that into our equation for horizontal distance. 

[tex]dx=vi_{x}t[/tex]
[tex]dx=(10m/s)(2.02s)[/tex]
[tex]dx=20.20m[/tex]

The horizontal distance of the rock will be 20.20m.
Final answer:

The rock strikes the water after traveling approximately 20.3 meters horizontally. This is calculated using principles of physics related to projectile motion, with the separate vertical and horizontal movements taking place simultaneously and independently.

Explanation:

The physics problem you've described deals with the concept of projectile motion. In this scenario, the horizontal and vertical movements of the rock can be analyzed separately. The vertical displacement doesn't affect the horizontal one given the negligible air resistance.

First, let's find the time it takes for the rock to hit the water below. We can use the equation of motion, d = 0.5*g*t², where g is the acceleration due to gravity (9.8 m/s²), and d is the vertical displacement (20 m). Solving for t, we get approximately 2.03 seconds.

Then, to find the horizontal distance that the rock traveled, we use the formula for velocity (v = d/t), rearranged to solve for distance: d = v*t. Here, v is the initial velocity of the rock (10 m/s) and t is the previously calculated time (2.03 seconds). Completing the calculation, we find that the horizontal distance the rock travels before striking the water is approximately 20.3 meters.

Frequency of an electromagnetic wave is the number of cycles or waves get in one second. Thus its unit is s-1. Frequency of first last some radiations in the spectrum that are UV, gamma, x-ray etc are higher and they have shorter wavelength.

High frequency waves are more energetic whereas longer wavelength  is associated with less energy. The relation between frequency v and wavelength lambda is written as follows:

This law talks about the tendency of an object to resist any change in its state of rest or uniform motion, this is called Inertia. Thus Newton's 1st law of motion is also called the Law of Inertia

Final answer:

Newton's first law of motion, also known as the law of inertia, states that an object at rest remains at rest and an object in motion remains in motion unless acted upon by an external force.

Explanation:

Newton's first law of motion states that a body at rest remains at rest or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. This law is also known as the law of inertia. Inertia is the tendency of an object at rest to remain at rest or, if moving, to remain in motion at constant velocity. Inertia is related to an object's mass.

Final answer:

The potential difference across the inductor is given by the equation VL = -L*I0*e^(-t/τ)*(1/τ). Plugging in L=15mH, I0=36mA, and τ=1.1ms, evaluations for t=0, 1ms, 2ms, and 3ms yield -0.49V, -0.27V, -0.15V, and -0.08V respectively.

Explanation:

The potential difference across the inductor, ΔVL, can be determined by using Faraday's law which states that the EMF in a circuit is equal to the rate of change of magnetic flux. In this case, it corresponds to:

VL = L*(dI/dt) = L * d/dt [I0*e^(-t/τ)] = -L*I0*e^(-t/τ)*(1/τ)

From this equation, the potential difference can be evaluated at different times.

At t=0s: ΔVL = -L*I0*1/τ = - (15x10^-3)*(36x10^-3)/1.1x10^-3 = - 0.49 V At t=1ms: ΔVL = -L*I0*e^(-t/τ)*(1/τ) = - (15x10^-3)*(36x10^-3)*e^(-1/1.1)(1/1.1x10^-3) = -0.27 V At t=2ms: ΔVL = - (15x10^-3)*(36x10^-3)*e^(-2/1.1)(1/1.1x10^-3) = -0.15 V At t=3ms: ΔVL = - (15x10^-3)*(36x10^-3)*e^(-3/1.1)(1/1.1x10^-3) = -0.08 V

L = 170 m at 30.0°C
ΔT = 30 - (-16) = 46°C

Substituting;
ΔL = 2.5*10^-6 *170*46 = 0.01955 m

Height at -16°C = 170 - 0.01955 = 169.98 m
