Answer:  The most massive car, x, will take the longest to reach 60 mph.

Explanation:  The inertia of a car is dependent on its mass.  F=ma.  Given that each car has the same force (identical engines) the one with the higher mass will accelerate more slowly.

Fuller pillows that keep her neck straight. The correct option is A.

Thus, Broader pillows that properly support her neck and head would be a better choice. Better sleeping posture and a lower incidence of neck and back pain can both be encouraged by pillows that keep the neck and spine in their natural alignment.

Flat pillows could not offer enough support, which could result in poor alignment and long-term discomfort or suffering.

Stacking pillows in Option B may provide some elevation, but it might not necessarily provide the essential neck and spine support. Option C (without using pillows) can fail to give the head and neck the necessary support and cushioning.

Thus, Fuller pillows that keep her neck straight. The correct option is A.

Let's consider the given terms ~

(Acceleration is negative bbecause train slows down)

(final velocity is 0, because train stops)

Now, let's find the time taken (t) by using the first equation of motion ~

The train will take 10 secs to stop,

Now, let's find how much distance (s) it will cover before it stops using second equation of motion ~

It will cover 500 meters before coming to rest ~

Answer:

Temporarily yes, if you are speaking of a skeletally mature person, taking pressure off of joints will allow them to absorb more fluid and thus be a larger diameter. If that expansion is in a vertical direction then you would in fact be taller until the fluid was returned to outside of the joint.

Answer: When a gas is in a smaller volume, the molecules are more confined and bump into the walls of the flask more, thereby exerting a greater pressure.

The magnitude of the magnetic field in the coil is 21.65 T.

The given parameters;

The induced emf in the coil is determined by applying Faradays law;

[tex]emf =N \frac{d\phi }{dt} \\\\emf = N ( \frac{\phi _2 - \phi_1}{t} )\\\\emf= N(\frac{BAsin\ 60 - BAsin\ 90}{t} )\\\\emf = NBA(\frac{sin60 - sn90}{t} )\\\\-0.058 = 500(6\times 10^{-4})\times B\times (\frac{0.866 - 1}{15} )\\\\-0.058 = -0.00268B\\\\B = \frac{0.058}{0.00268} \\\\B = 21.65 \ T[/tex]

Hi there!

The equation for the kinetic friction force is:

We can begin by doing a summation of forces acting on the couch where a positive force is in the direction of the couch's acceleration, or in the direction of the push.

Thus:

[tex]\Sigma F = F_A - F_{kf}[/tex]

Now, plug in the values:

[tex]\large\boxed{\text{Friction.}}[/tex]

We can go through each:

1) Inertia is NOT a force. Inertia is defined as an object's resistance to motion, or its mass.

2) Friction IS a force because it results in acceleration.

3) Acceleration is not a force, but rather a product of force.

4) Velocity is simply a quantity that can be changed as a result of a force.
