A can of corn heas a diameter of 6.6 centimeters and a height of 9.9 centimeters. How much corn can tue can hold?

Answer:

Both eggs are identical. The aim is to find out the highest floor from which an egg will not break when dropped out of a window from that floor. If an egg is dropped and does not break, it is undamaged and can be dropped again. However, once an egg is broken, that's it for that egg.

Force is measured in Newton ( kg.m. /s²)

Impairs one's ability to functionExplanation:

I just took the test

Answer:

Increases

Explanation:

For a given force, as the time increases, the impulse related to that force increases also.

Impulse and time are directly related to one another. Impulse is mathematically given as:

           I  = F t

I is the impulse

F is the force

t is the time taken

So, as both force and time increases, the value of the impulse must increase.

Answer:

burns

Explanation:

For this we have the hidrostatic equation:

[tex]\boxed{P = \rho gh}[/tex]

Being:

P = Pressure

ρ = Density of liquid (water) = 1000 kg/m

g = Gravity = 9,81 m/s²

h = Height = 4 m

Replacing acording formula:

[tex]\boxed{P = 1000 \ kg/m ^{3} * 9,81 \ m/s^{2} * 4 \ m}[/tex]

Resolving:

[tex]\boxed{P = 39240 \ Pa}[/tex]

Result:

The pression at the bottom is 39240 Pa.

Answer:

540m/s

Explanation:

Given parameters:

Frequency of the wave = 18000Hz

Wavelength of the wave = 0.03m

Unknown:

How fast is the wave traveling = ?

Solution:

How fast the wave is traveling is a measure of the speed of the wave;

     Speed of wave  = frequency x wavelength

Now insert the given parameters and solve;

   Speed of wave  = 18000 x   0.03  = 540m/s

Answer:

C. 211.5 N

Explanation:

We included a free body diagram representation of the concrete block. The equation of equilibrium in the x-direction:

[tex]\Sigma F_{x} = P\cdot \cos \alpha -\mu_{k}\cdot N = m\cdot a[/tex] (1)

[tex]\Sigma F_{y} = N + P\cdot \sin \alpha -m\cdot g = 0[/tex] (2)

Where:

[tex]P[/tex] - External force exerted on the block, measured in newtons.

[tex]N[/tex] - Normal force from the ground to the block, measured in newtons.

[tex]\alpha[/tex] - Direction of the external force, measured in sexagesimal degrees.

[tex]\mu_{k}[/tex] - Kinetic coefficient of friction, dimensionless.

[tex]m[/tex] - Mass of the concrete block, measured in kilograms.

[tex]g[/tex] - Gravitational acceleration, measured in meters per square second.

[tex]a[/tex] - Net acceleration of the concrete block, measured in meters per square second.

The minimum force to move block occurs when net force is zero, from (2) we get that the normal force is:

[tex]N = m\cdot g -P\cdot \sin \alpha[/tex]

And by applying this formula in (1), we get that the external force is:

[tex]P\cdot \cos \alpha - \mu_{k}\cdot (m\cdot g -P\cdot \sin \alpha) = m\cdot a[/tex]

[tex]P\cdot \cos \alpha -\mu_{k}\cdot m\cdot g +\mu_{k}\cdot P\cdot \sin \alpha = 0[/tex]

[tex]P\cdot (\cos \alpha +\mu_{k}\cdot \sin \alpha)=\mu_{k}\cdot m\cdot g[/tex]

[tex]P = \frac{\mu_{k}\cdot m\cdot g}{\cos \alpha +\mu_{k}\cdot \sin \alpha}[/tex]

If we know that [tex]\mu_{k} = 0.75[/tex], [tex]m = 35\,kg[/tex], [tex]g = 10\,\frac{m}{s^{2}}[/tex] and [tex]\alpha = 30^{\circ}[/tex]. then the external force is:

[tex]P = \frac{(0.75)\cdot (35\,kg)\cdot \left(10\,\frac{m}{s} \right)}{\cos 30^{\circ}+0.75\cdot \sin 30^{\circ}}[/tex]

[tex]P \approx 211.518\,N[/tex]
