6. You must turn on your headlights
A. before starting your vehicle
O B. whenever you use your windshield wipers
C. when vehicles cannot be seen at a distance of 2,000 ft.

Answers

The most logical answer would be C :)

You must turn on your headlights whenever you use your windshield wipers. The correct option is option B.

In many jurisdictions, it is a legal requirement to turn on your headlights whenever you are using your windshield wipers. This is because using windshield wipers typically indicates reduced visibility due to rain, snow, or other adverse weather conditions.

By turning on your headlights, you increase your visibility to other drivers on the road, enhancing safety.

Therefore, You must turn on your headlights whenever you use your windshield wipers. The correct option is option B.

3) F= ?, m= 18 kg, a= 2 m/s2

help me pweeeees

Answers

Answer:

1) False

2) True

3) 36N

Explanation:

1) Quantitative observation is related to number of objects . But in that example , there isn't any number.

2) Potential energy depends on height. So potential energy increases when height increases.

3) F = m×a

In the question , m = 18 kg ; a = 2m/s^2

So, F = 18×2 = 36N

Explanation:

The axis of a circular cylinder coincides with the z-axis and it rotates with an angular velocity of (3i−5j +9k) rad/s. Determine i. The tangential velocity at a point P on the cylinder, whose co-ordinates are ( j +5k) metres,

Answers

Answer:

The tangential velocity at point P is [tex]\vec v_{P} = -34\,\hat{i} -15\,\hat{j}+3\,\hat{k}\,\,\left[\frac{m}{s} \right][/tex].

Explanation:

Vectorially speaking, we define tangential velocity at point P ([tex]\vec v_{P}[/tex]), measured in meters per second, by the following vectorial expression:

[tex]\vec v_{P} = \vec \omega \times \vec r_{P}[/tex] (1)

Where:

[tex]\vec \omega[/tex] - Angular velocity of the cylinder, measured in radians per second.

[tex]\vec r_{P}[/tex] - Radius of rotation, measured in meters.

If we know that [tex]\vec \omega = 3\,\hat{i}-5\,\hat{j}+9\,\hat{k}\,\left[\frac{rad}{s} \right][/tex] and [tex]\vec r_{P} = \hat{j}+5\,\hat{k}\,[m][/tex], then the tangential velocity at point P is:

[tex]\vec v_{P} = \left|\begin{array}{ccc}\hat{i}&\hat{j}&\hat{k}\\3\,\frac{rad}{s} &-5\,\frac{rad}{s} &9\,\frac{rad}{s} \\0\,m&1\,m&5\,m\end{array}\right|[/tex]

[tex]\vec v_{P} = \left[\left(-5\,\frac{rad}{s} \right)\cdot (5\,m)-(1\,m)\cdot \left(9\,\frac{rad}{s} \right)\right]\,\hat{i}-(5\,m)\cdot \left(3\,\frac{rad}{s}\right)\,j +\left(3\,\frac{rad}{s} \right)\cdot (1\,m)\,\hat{k}[/tex]

[tex]\vec v_{P} = -34\,\hat{i} -15\,\hat{j}+3\,\hat{k}\,\,\left[\frac{m}{s} \right][/tex]

The tangential velocity at point P is [tex]\vec v_{P} = -34\,\hat{i} -15\,\hat{j}+3\,\hat{k}\,\,\left[\frac{m}{s} \right][/tex].

Answers

Answer:

The speed with which the man flies after hitting the rock is 5.5 m/s

Explanation:

The given parameters are;

The mass of the man, m₁ = 100 kg

The mass of the scooter, m₂ = 10 kg

The initial speed of the man and the scooter, v₁ = 5 m/s

The speed with which the man flies after hitting the rock = v₂

The final speed of the scooter, v₃ = 0 m/s

The momentum = Mass × Velocity and by the principle of conservation of momentum, we have;

The total initial momentum = The total final momentum

The total initial momentum = (m₁ + m₂) × v₁ = (100 + 10) × 5 = 550

The total initial momentum = 550 kg·m/s

The total final momentum = m₁ × v₂ + m₂ × v₃, which gives;

The total final momentum = 100 × v₂ + 10 × 0

By conservation of momentum, the total initial momentum = The total final momentum, we get;

550 = 100 × v₂ + 10 × 0

∴ 550 = 100 × v₂

v₂ = 550 kg·m/s/(100 kg) = 5.5 m/s

The speed with which the man flies after hitting the rock = v₂ = 5.5 m/s

A rock is dropped into a canyon that is 0.3 km deep. Determine the time it takes the rock to hit the bottom of the canyon?

Answers

Answer:

rock of mass m is dropped to the ground from a height h. A second rock, with mass 2m, is dropped from the same height. When the second rock strikes the ground, what is its kinetic energy? (a) Twice that of the first rock, (b) four times that of the first rock, (c) same as that of the first rock, (d) half as much as that of the first rock, (e) impossible to determine.

If a  rock is dropped into a canyon that is 0.3 km deep, then the time taken by the rock to hit the bottom of the canyon would be 7.82 seconds.

What are the three equations of motion?

There are three equations of motion given by  Newton

v = u + at

S = ut + 1/2 × a × t²

v² - u² = 2 × a × s

Keep in mind that these calculations only apply to uniform acceleration.

As given in the problem, if a rock is dropped into a canyon that is 0.3 km deep.

By using the second equation of motion given by Newton,

S = ut + 1/2at²

300 = 0 + 0.5 × 9.8 × t²

t² = 300 / 4.9

t = 7.82 seconds

Thus,  the time taken by the rock to hit the bottom of the canyon would be 7.82 seconds.

A car is travelling along the road where the speed limit is 30 mph. A speed detector measures it speed as 15 m/s. Use this fact to work out whether or not the car is breaking the speed limit: there are 1609 m in a mile

Answers

Answer:

The speed of the car is in from as the required speed limit on the road.

Explanation:

The speed limit on the road is 30 miles per hour.

Given that: 1 mile = 1609 m

Also,

60 second = 1 minutes

60 minutes = 1 hour

Then,

30 miles per  hour = [tex]\frac{30 *1609}{60*60}[/tex]

                              = [tex]\frac{48270}{3600}[/tex]

                              = 13.4083

30 miles per  hour  = 13.41 m/s

The speed measured by the detector is 15 m/s which is not accurate. Therefore, the car was moving at the required speed limit. The speed of the car is lesser than that measured by the detector. Thus no offence has been committed by the driver.

Sonya pushes his friend down the road on his new wagon. Which two terms accurately describe the net force acting on the sled?
Group of answer choices

balanced and contact

unbalanced and noncontact

balanced and noncontact force

unbalanced and contact

Answers

Answer:

unbalanced and contact

Explanation:

The two terms that bests describes the net force acting on the sled is an unbalanced and contact force.

Force is a pull or push on a body. We have two main types of forces. Contact forces acts on a body and they must be in touch with it. An example is frictional force.

Non - contact forces acts based on force field and they are not in contact with the body. An example is gravitational force.

Since the sled is sliding down the road, it is changing velocity and so, unbalanced forces are acting on it.

Therefore, the force on the wagon is an unbalanced and contact force.

An asteroid orbits the Sun every 176 years. What is the asteroids average distance from the Sun? P ^ 2 = a ^ 3 where p = period in years and average orbital distance in AU 233 years 1.46 AU 5.45 years 3.09 years

Answers

Answer:

The value is  [tex]x = 45.99 \ Au[/tex]

Explanation:

From the question we are told that

   The period of the  asteroid is   [tex]T = 176 \ years = 176 * 365 * 24 * 60* 60 = 5.55*10^{9}\ s[/tex]

Generally the average distance of the asteroid from the sun is mathematically represented as

            [tex]R = \sqrt[3]{ \frac{G M * T^2 }{4 \pi} }[/tex]

Here M is the mass of the sun with a value  

        [tex]M = 1.99*10^{30} \ kg[/tex]

         G  is the gravitational constant with value  [tex]G = 6.67 *10^{-11} \ m^3 \cdot kg^{-1} \cdot s^{-2}[/tex]

           [tex]R = \sqrt[3]{ \frac{6.67 *10^{-11} * 1.99*10^{30} * [5.55 *10^{9}]^2 }{4 * 3.142 } }[/tex]

=>       [tex]R = 6.88 *10^{12} \ m[/tex]

Generally

         [tex]1.496* 10^{11} \ m \to 1 Au (Astronomical \ unit )[/tex]

So

          [tex]R = 6.88 *10^{12} \ m \ \ \ \ \to \ \ x \ Au[/tex]

=>      [tex]x = \frac{6.88 *10^{12}}{1.496 *10^{11}}[/tex]

=>       [tex]x = 45.99 \ Au[/tex]
