Explanation:

Urine is a liquid by-product of metabolism in humans and in many other animals. Urine flows from the kidneys through the ureters to the urinary bladder. Urination results in urine being excreted from the body through the urethra.

Answer:

It demonstrates that the narrator is surrounded by nature.

Explanation:

Walt Whitman's "Crossing the Brooklyn Ferry" is a free verse poem written about the speaker's return trip on a ferry. He talks about his daily commute on the Brooklyn ferry, like the other commuters, and how they all share the same experience.

The given lines are from the very first stanza of the poem. The speaker repeats "face-to-face" when talking about nature. He sees the "flood-tide below" and the "clouds" high in the sky. This repetition demonstrates that he is surrounded by nature, amidst the throng of people around him. This shows the speaker's attitude of seeing the beauty of nature in any way he can, despite the bustle of commuting from Brooklyn to Manhattan.

Thus, the correct answer is the second option.

The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.

Answer:

The unit of speed is m/s.

Answer:

Light propagating in a plane that makes a 0 degree angle with the polarizer will pass through and all other planes will only pass the component of the vector that is in line with the polarizer. What the image suggests, and other images like the second one, is that the light is now all propagating parallel to a single plane

Explanation:

hope this helps

Answer:

true

Explanation:

a polarizer allows only light of a specific wavelength to pass through

Answer:

0 Joules.

Explanation:

Given the following data;

Mass = 80kg

Height = 10m

Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.

Mathematically, gravitational potential energy is given by the formula;

[tex] G.P.E = mgh[/tex]

Where;

G.P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

We know that acceleration due to gravity is equal to 9.8m/s²

But since we're determining the gravitational potential energy just before the driver jump, the height would be zero (0) meters.

Gravitational potential energy= mgh

Gravitational potential energy = 80*9.8*0

Gravitational potential energy = 0 Joules.

This ultimately implies that, if an object or body hasn't moved (jumped) from its reference point, its gravitational potential energy would be equal to zero.

Answer:

[tex]\boxed {\boxed {\sf 8 \ m/s}}[/tex]

Explanation:

Speed is equal to distance over time.

[tex]s=\frac{d}{t}[/tex]

The distance is 400 meters and the time is 50 seconds.

[tex]d= 400 \ m \\t= 50 \ s[/tex]

Substitute the values into the formula.

[tex]s=\frac { 400 \ m }{ 50 \ s}[/tex]

Divide.

[tex]s= 8 \ m/s[/tex]

The speed of the car is 8 meters per second.

Answer:

1. True.

2. False.

3. True.

Explanation:

A. True: An object has acceleration if its velocity is changing. In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

B. False: Force is measured in joules. Force is a product of the mass of an object and its rate of acceleration. Thus, force is actually measured in Newton.

C. Gravity is a force. Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.

Answer:

both an electric field and a magnetic field

Explanation:

The sound level will be 109 decibels. If a person exceed hear a sound more than the certain sound level, the person hearing may damage.

Sound level is the intensity to measure the sound. Decibels are used to quantify sound level.

Sound level or the sound intensity is the ratio of  the power to the surface area;

[tex]\rm Intensity = \frac{Pow\pi er }{Surface \ area} \\\\ \rm Intensity = \frac{70}{ 4 \times \pi \times 8 \times 20^{2} } \\\\ I = \ 0.082 \ W/m^2[/tex]

The conversion of  the obtained value into the decibel as;

[tex]\rm I = 10 \times log \frac{I}{1 \TIMES 10^{-12}} \\\\\ I = 109 \ decibel[/tex]

Hence, the sound level will be 109 decibels.

Answer:

It can be seen from the operation of pin-hole camera, formation of shadows and eclipse.

Explanation:

The phenomenon of light traveling in a straight line is known as rectilinear propagation of light.

One this evidence can be seen from the operation of pin-hole camera, which depends on rectilinear propagation of light

Also two natural effects that result from the rectilinear propagation of light are the formation of Shadows and Eclipse.

Explanation:

Jenny and anne wanted to see who could throw the ball the hardest. they decided to each throw a ball against the wall as hard as they could and measured how far the ball rolled away from the wall. what might be the variables in this experiment;

Solution:

There are different type of collisions. In an inelastic collision, momentum is conserved and there is loss in kinetic energy while in an elastic collision, momentum is not conserved and there is no loss in kinetic energy.

During inelastic collision, the objects stick together while during an elastic collision, the objects separate.

When the ball is thrown against the stationary wall, there is momentum due to the force of impact. The distance at which the ball is rolled away from the wall depends on:

a) mass of the ball, b) velocity of the ball, c) mass of the wall d) type of collision (elastic or inelastic)
