A book is sitting on a table. Which of the following is true about the table? O A. It is pushing up on the book. O B. It exerts no force on the book at all. O C. It is pulling down on the book. D. It can affect the mass of the book.
Answer:
yes it does exert a force, it pushes it up
Explanation:
this is called normal force
if it didn't exert a force the book would keep going down
according to newton every force has an equal amd opposite reaction
so the book exerts a force on the table and vice versa

F. A 50. A resistor (R2), and unknown resistor R2, a 120 Volt source, and an ammeter are connected in a
complete circuit. The ammeter reads 0.50 ampere (current).
R1
a. Determine the resistance of Rz.
R2
Complete question is;
A 50.-ohm resistor, an unknown resistor R, a 120-volt source, and an ammeter are connected in a complete circuit. The ammeter reads 0.50 ampere.
A) Calculate the equivalent resistance of the circuit shown.
B) Determine the resistance of resistor R shown in the diagram.
Answer:
A) R_eq = 240 Ω
B) R = 190 Ω
Explanation:
A) To get the equivalent resistance, we will use the formula;
R = V/I
Where;
V is Voltage
I is current
R is equivalent resistance
From the question, V = 120 V and I = 0.5A
Thus;
R_eq = 120/0.5
R_eq = 240 Ω
B) From the image, we see that the resistors are connected in series.
Formula for resistors in series is;
R = R1 + R2 +..... Rn
Thus;
240 = 50 + R
R = 240 - 50
R = 190 Ω
A) The equivalent resistance of the circuit shown will be 240 Ω.
B) The resistance of resistor R will be 190 Ω
What is resistance?Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.
The given data in the problem is;
R is the resistance = 50.-ohm
v is the voltage = 120-volt source
I is the value of the current =0.50 ampere.
A) The equivalent resistance of the circuit shown will be 240 Ω.
According to ohm's law
[tex]\rm R= \frac{V}{I} \\\\ \rm R= \frac{120}{0.5} \\\\ \rm R=240 \ ohm[/tex]
Hence the equivalent resistance of the circuit shown will be 240 Ω.
B) The resistance of resistor R will be 190 Ω
The given resistors are connected in the series;
R = R1 + R2 +..... Rn
240 = 50 + R
R = 240 - 50
R = 190 Ω
Hence the resistance of resistor R will be 190 Ω

44. Two wave pulses are traveling along a string
toward each other as represented in the diagram
below.
(D is interference)
The phenomenon of interference occurs when two wave pulses are traveling along a string toward each other. Option D is correct.
What is the interference of waves?The result of two or more wave trains flowing in opposite directions on a crossing or coinciding pathways. This phenomenon is known as the interference of waves.
The effect is the sum of the individual wave amplitudes at each site where more than one wave is present.
When two wave pulses are traveling along a string toward each other. They meet and the phenomenon is occur known as interference.

Each bat can produce different frequencies of ultrasound. Explain why this is useful if there are many bats hunting together.
Answer: Although low frequency sound travels further than high-frequency sound, calls at higher frequencies give the bats more detailed information--such as size, range, position, speed and direction of a prey's flight. Thus, these sounds are used more often.

Why is ultraviolet radiation considered more dangerous to humans than infrared radiation?
ANSWER:Ultraviolet radiation has a shorter wavelength than infrared radiation, and thus, the waves have higher energy. This allows them to penetrate the first layers of skin on humans and can mutate the DNA in the cells of the skin. This can result in cancer because of the mutations caused by the ultraviolet radiation.

What happens to the force between charged and uncharged objects as the distance between them decreases?
Answer:Thus, if each of the charges were reduced by one-half, the repulsion would be reduced to one-quarter of its former value. Also In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. ... And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects.
Hope this helps have a awesome night/day❤️✨
Explanation:
Nothing, until those two objects physically touch each other; contact aligns polarity among the now single shared mass.
(Your question never states if both objects are unique or similar polar charges, so I just assumed they were both neutral objects existing within an electric field.)
So a better question would then be, what is gravity’s relationship with an electric field?
You could solve this with the following: confine the electric field’s volume to a set variable (never increasing nor decreasing in size or shape); density is variable and easily definable. This creates the limit to build upon. This density has to be fluid and has electron mass (full of electrons at rest mass, so with substance but no movement). Within, create a closed system (the hard part in this equation; outside interference like ambient light will eschew results) where each variable of kinetic energy then is accounted for or measurable (including heat and light, and the physical movement of the two objects)
Determine the mass for both objects, calculate gravity for both and each body’s inertia on the other as a sum over distance. record results. Polarity is shared across the masses until there is no longer inertia (one mass or contact).

The Escape speed at the surface of a certain planet is twice that of the earth. If the planet has radius twice of the Earth. what is its mass in unit of earth's mass?
Answer:
1.32 × 1022 short tons
Explanation:
hope this helps
The required mass of the planet is 8 times the mass of the earth.
Given that,
The Escape speed at the surface of a certain planet is twice that of the earth. The planet has a radius twice of the Earth. what is its mass in unit of earth's mass is to be determined.
An object with this velocity at the earth's surface will completely escape the earth's gravitational field, even after accounting for atmospheric losses.
here,
The escape velocity of the planet = 2 Escape velocity of the earth
[tex]\sqrt{{2GM_p}/r_p} = 2\sqrt{2GM_e/r_e}[/tex]
Substitute the values and square both sides,
[tex]{{2GM_p}/2r_e} = 4*{2GM_e/r_e}\\M_p = 8M_e[/tex]
Thus, the required mass of the planet is 8 times the mass of the earth.
