A. 4.96 m
Explanation:
Using the formula for a wavelength:
Wavelength = velocity / frequaency
Using the provided information you have:
Wave length = 300,000,000 m/s / 60,500,000 HZ
Divide to get: 4.958 meters
Round to 4.96 meters
Figure one, voltmeters
Answer:
(i) Half
(ii) 3 V
(iii) V₁
Explanation:
(i) The given parameters are;
The circuits have identical resistances
The number of resistors in circuit 1 = 1 resistor
The number of resistors in circuit 2 = 2 resistors
Let 'R' represent the value of each resistor, we have;
The total resistance of circuit 1 = R Ohm
The total resistance of circuit 3 = 2·R Ohm
∴ The total resistance of circuit 1 = (1/2) × The total resistance of circuit 3
∴ The resistance of circuit 1 is half the resistance of circuit 3
(ii) The potential difference of each cell, V = 1.5 volts
The number of cells in circuit 2 = 2 cells
The total potential difference of the cells of circuit 2 = 2 × 1.5 volts = 3 × volts = 3 V.
The voltmeter reading = The potential difference across the cell or cells it is applied
∴ The voltmeter reading on voltmeter, V₂, applied across the cells of circuit 2 = 3 V
(iii) The voltmeter reading V₁ = 1.5 V
The voltmeter reading V₂ = 3 V
The voltmeter reading V₃ = 4.5/(2·R) × R = 2.25 V
Therefore, the voltmeter reading with the smallest volt, is V₁ = 1.5 V
During a lab investigation, students added four 50 g masses to two boxes and arranged the boxes so that they were motionless on a pulley, as shown in the diagram. The students then followed the procedure described in the box. The students recorded their observations after
each procedure and reset the pulley system to the original conditions.
During which procedures did students observe an unbalanced upward force on Box 1?
Group of answer choices
Procedures 4 and 5
Procedures 3 and 4
Procedures 1, 2, and 3
Procedures 1, 3, and 5
Answer:
Procedures 4 and 5.
Explanation:
Both would cause the box to move up.
4, it becomes lighter
5, the other becomes heavier, pulling it down, causing box one to go up
Since we seek the action of force to push up box 1, the students observes an unbalanced upward force on Box 1 in procedures 4 and procedure 5.
In what procedures did students observe an unbalanced upward force on Box 1?Generally, In procedure 4 we added another mass to the box two, therefore, causing box one to experience an upward force.
Therefore, students observe an unbalanced upward force on Box 1 in procedure 4.
Procedure 5 we remove masses from box 1 resulting in box 2 becoming heavier, pulling it down.
Therefore, students observe an unbalanced upward force on Box 1 in procedure 5.

Why is the sum of forces/net force less than the applied force? Think about the direction of the forces in your answer
Answer:
he same direction the magnitude of the resultant is equal to the scalar sum of the magnitude of the forces, but if they are applied in different directions the magnitude must be found using the Pythagorean theorem
Explanation:
When there are several applied forces, if they are all in the same direction the magnitude of the resultant is equal to the scalar sum of the magnitude of the forces, but if they are applied in different directions the magnitude must be found using the Pythagorean theorem, so which the resulting dowry is less than the sum of the magnitudes.
Let's carry out an example with two forces, F1 and F2 of equal magnitudes
if they are in the same direction
F_total = F₁ + F₂ = 2 F
if they are at 90º
F_total = [tex]\sqrt{F_1^2 + F_2^2}= \sqrt{2} \ F[/tex]
if they are at 180º
F_total = F₁ -F₂ = 0

A 170.0 g sample of a substance is heated to 120.0 °C and then plunged into 200.0 mL of water at 10.0 °C. The resulting mixture has a temperature of 12.6 °C. What is the specific heat capacity of the substance?
I'LL GIVE BRAINLIEST!!!!
Answer:
Heat Lost = (120 - 12.6) deg * 170 g * S = `18260 gm-deg * S
Heat Gained = (12.6 - 10) deg * 200 gm* 1 cal/ gm-deg - 520 cal
S = 520 / 18260 cal / gm-deg = .0285 cal / gm-deg
Since Heat Lost = Heat Gained
Savion listed the steps involved when nuclear power plants generate electricity.
Nuclear reaction occurs.
Nuclear energy is converted to radiant and thermal energy.
Heat is used to generate steam.
Light and heat are released.
Steam turns turbines.
Mechanical energy is converted to electrical energy.
Which best explains how to correct Savion’s error?
In step 2, change “radiant and thermal ” to “chemical and mechanical.”
Reorder the steps so that step 4 appears before step 3.
Reorder the steps so that step 6 appears before step 5.
In step 6, change “mechanical” to “thermal.”
Answer:
Reorder the steps so that step 4 appears before step 3
Explanation:
In a nuclear power plant, we have;
1) Nuclear reaction between the radio active species and the particles takes place to generate energy in the nucleus of atoms
2) The nuclear energy in the atom is converted into radiant energy, which is the energy found in light, and thermal (heat) energy
3) The produced radiant and thermal energy is released as heat and light
4) With the produced heat, steam is generated
5) The generated steam turns the steam turbines and produced mechanical energy
6) The produced mechanical energy is then converted into electrical energy in the electrical generator of the power plant
To correct Savion's error, Step 4) the light and heat should be released before step 3) the released heat can be used to generate steam, we therefore reorder the steps so that step 4 appears before step 3.

A 55 kg box rests on a horizontal surface. The coefficient of kinetic friction between the box and the surface is 0.30. If the box is pulled at constant velocity over the horizontal surface with horizontal applied force, what is the magnitude of the force of friction and the force applied?
Answer: [tex]161.7\ N[/tex]
Explanation:
Given
Mass of the box is [tex]m=55\ kg[/tex]
Coefficient of kinetic friction [tex]\mu_k=0.3[/tex]
Kinetic friction comes into play when the body is moving
Here, kinetic friction opposes the applied force
kinetic friction is [tex]\mu_kmg[/tex]
thus, the applied force is
[tex]F=\mu_kmg\\F=0.3\times 55\times 9.8\\F=161.7\ N[/tex]

7. A very wealthy donor decides to give a large sum of money to your college or university to build the world's largest visible-light gathering telescope. From an astronomical perspective, where would be the best location to put such a telescope? a. in a dark spot right on the campus b. on the west coast of the U.S. very close to sea level (a location like Seattle, for example) c. close to a large city where there are many astronomers to use it d. on a tall, dry mountain peak e. Bayonne, New Jersey
Answer:
the correct answer is d
on a tall, dry mountain peak
Explanation:
A telescope is an instrument that allows the observation of distant bodies whose light is very dim, for this the telescope concentrates a large amount of light with large diameter lenses or mirrors.
The location of a telescope must take into account several aspects:
* The most important that there are no nearby lights that disturb the observation, so it must be away from cities and other strong light sources.
* The climate should be as stable as possible with few temperature variations, to prevent the optical surfaces from fogging up and reducing the thermal expansion that changes the length of the instrument.
* You must choose a place with little rain and therefore little amount of clouds
Based on these needs we can answer which luxury will be the most suitable
a) There is a lot of light nearby
b) there is a lot of humidity and wind
c) there is a lot of light
d) This is an ideal place with low light, low humidity and stability in the climate
e) lots of humidity and light
so the correct answer is d

Un neumático sin cámara, soporta una presión de 1.5 atm cuando la temperatura ambiente es de 300°K. ¿Qué presión llegará a soportar dicho neumático si, en el transcurso de un viaje, las ruedas alcanzan una temperatura de 67ºC? Atm
Answer:
El neumático soportará una presión de 1.7 atm.
Explanation:
Podemos encontrar la presión final del neumático usando la ecuación del gas ideal:
[tex] PV = nRT [/tex]
En donde:
P: es la presión
V: es el volumen
n: es el número de moles del gas
R: es la constante de gases ideales
T: es la temperatura
Cuando el neumático soporta la presión inicial tenemos:
P₁ = 1.5 atm
T₁ = 300 K
[tex] V_{1} = \frac{nRT_{1}}{P_{1}} [/tex] (1)
La presión cuando T = 67 °C es:
[tex] P_{2} = \frac{nRT_{2}}{V_{2}} [/tex] (2)
Dado que V₁ = V₂ (el volumen del neumático no cambia), al introducir la ecuación (1) en la ecuación (2) podemos encontrar la presión final:
[tex] P_{2} = \frac{nRT_{2}}{V_{2}} = \frac{nRT_{2}}{\frac{nRT_{1}}{P_{1}}} = \frac{P_{1}T_{2}}{T_{1}} = \frac{1.5 atm*(67 + 273)K}{300 K} = 1.7 atm [/tex]
Por lo tanto, si en el transcurso de un viaje las ruedas alcanzan una temperatura de 67 ºC, el neumático soportará una presión de 1.7 atm.

Where do human get the stuff they need to survive?
Answer:
Humans survive through gaining nutrients by eating
Answer:
We must have food, water, air, and shelter to survive. If any one of these basic needs is not met, then humans cannot survive. Oxygen is one of the most essential human needs. Our bodies need a consistent supply of it to function properly. Without access to oxygen, you can experience a condition known as cerebral hypoxia, which affects the brain. As little as five minutes without air can result in brain damage. We get food from plants and animals, we get water from rivers and streams, and we get shelter from building anything that is around.
