Answer:

The downward force does it need to exert in order to maintain equilibrium is 76.974 N

Explanation:

The downward force does it need to exert in order to maintain equilibrium is:

F=\frac{mgL}{x}

Where

m = mass of human head = 4.8 kg

g = gravity = 9.8 m/s²

L = center of mass = 1.8 cm = 0.018 m

x = distance = 1.1 cm = 0.011 m

Replacing:

F=\frac{4.8*9.8*0.018}{0.011} =76.974N

krek1111 [17]

Answer:

The distance is 6259.31 meters.

Explanation:

We shall use the Reyligh criterion to solve the problem

For diffraction due to circular aperture we have

Assuming that human eye is circular we have

\frac{x}{D}=\frac{1.22\lambda }{d}

\therefore D=\frac{xd}{1.22\lambda }

Applying the given values we have

D=\frac{1.40\times 3\times 10^{-3}}{1.22\times 550\times 10^{-9}}\\\\\therefore D=6259.31m\\D=6.26km

An ocean liner is cruising at 10 meters/second and is about to approach a stationary ferryboat. A parcel is released from the oc
Afina-wow [57]
The parcel will undergo projectile motion, which means that it will have motion in both the horizontal and vertical direction.

First, we determine how long the parcel will fall using:

s = ut + 1/2 at²

where s will be the height, u is the initial vertical velocity of the parcel (0), t is the time of fall and a is the acceleration due to gravity. 

5.5 = (0)(t) + 1/2 (9.81)(t)²
t = 1.06 seconds

Now, we may use this time to determine the horizontal distance covered by the parcel by using:
distance = velocity * time

The horizontal velocity of the parcel will be equal to the horizontal velocity of the cruise liner.

Distance = 10 * 1.06
Distance = 10.6 meters

The boat should be 10.6 meters away horizontally from the point of release.

A fish is 80 cm below the surface of a pond. What is the apparent depth (in cm) when viewed from a position almost directly abov
Rudik [331]

Answer:

Apparent depth (Da) = 60.15 cm (Approx)

Explanation:

Given:

Distance from fish (D) = 80 cm

Find:

Apparent depth (Da)

Computation:

We know that,

Refractive index of water (n2) = 1.33

So,

Apparent depth (Da) = D(n1/n2)

Apparent depth (Da) = 80 (1/1.33)

Apparent depth (Da) = 60.15 cm (Approx)

If there is a potential difference v between the metal and the detector, what is the minimum energy emin that an electron must h
beks73 [17]
The electrical potential energy of a charge q located at a point at potential V is given by
U=qV
Therefore, if the charge must move between two points at potential V1 and V2, the difference in potential energy of the charge will be
\Delta U = q (V_2 -V_1)=q \Delta V

In our problem, the electron (charge e) must travel across a potential difference V. So the energy it will lose traveling from the metal to the detector will be equal to 
\Delta U = e V
Therefore, if we want the electron to reach the detector, the minimum energy the electron must have is exactly equal to the energy it loses moving from the metal to the detector:
E_{min} = \Delta U = eV
