please please please hellpppppppp!!!!!!
Answer:
The Answer is A
Explanation:
Does the mass of the objects you are charging influence the amount of electric force created in an electric field?
Explanation:
Both gravitational and electric forces decrease with the square of the distance between the objects, and both forces act along a line between them. In Coulomb's law, however, the magnitude and sign of the electric force are determined by the electric charge, rather than the mass, of an object.

A Physics student builds a circuit as shown with the help of a battery, wires, switch and 2 light bulbs as shown.
Which of the following circuit elements should the student use to cause the bulbs to dim but not go out?
Answer:b
Explanation:
Because I don’t know
The circuit elements should be placed according to the diagram given in option B to cause the bulbs to dim but not to go out. Thus, the correct option is B.
What are the elements of an electric circuit?An electric circuit is the continuous closed path along which the electric current flows from the positive terminal of the circuit to the negative terminal of the battery. An electric circuit can be constructed easily by joining all the elements of the circuit together in order.
The components of an electric circuit are:
A cell or a battery, which is the source of electricity.
The connecting wires which act as conductor to flow electric current.
A key or a switch to control the current through the circuit.
A bulb or electric device which act as a load to the circuit.
The length of the electric wire increases the resistance through the circuit and decreases the current flowing through the circuit which in turn dims the bulb.
Therefore, the correct option is B.

a ball of mass 2 kg moving at 30 m/s
a ball of mass 3 kg moving at 20 m/s'
a ball of mass 4 kg moving at 30 m/s
a ball of mass 5 kg moving at 20m/s
Answer:
4 kg at 30 m/s
Explanation:
comparing in pair, the 3rd is more than the 1st, and the 4th is more than the 2nd, so it boils down to the lasts two. calculate, and im pretty sure you get 4 kg at 30 m/s...
Momentum of a ball of mass 2 kg moving at 30 m/s = 2 kg × 30 m/s = 60 kg m/s
Momentum of a ball of mass 3 kg moving at 20 m/s = 3 kg × 20 m/s = 60 kg m/s
Momentum of a ball of mass 4 kg moving at 30 m/s = 4 kg × 30 m/s = 120 kg m/s
Momentum of a ball of mass 5 kg moving at 20 m/s = 5 kg × 20 m/s = 100 kg m/s
So, highest momentum is of a ball of mass 4 kg moving at 30 m/s (120 kg m/s).

Now consider θc, the angle at which the blue refracted ray hits the bottom surface of the diamond. If θc is larger than the critical angle θcrit, the light will not be refracted out into the air, but instead it will be totally internally reflected back into the diamond. Find θcrit.
Answer:
θ_c = 24.4º
Explanation:
To find the critical angle, let's use the law of refraction where index 1 refers to the incident medium (diamond) and index 2 refers to the medium where it is to be refracted (air)
n₁ sin θ₁ = n₂ sin θ₂
for the critical angle the ray comes out refracted parallel to the surface, therefore the angle is
θ₂ = 90
n₁ sin θ₁ = n₂
θ_c = θ₁ = sin⁻¹ [tex]\frac{n_2}{n_1}[/tex]
the index of refraction of the diamond is tabulated
n₁ = 2.419
let's calculate
θ_c = sin⁻¹ ([tex]\frac{1}{2.419}[/tex])
θ_c = 24.4º

Calculate the percentage of the Sun's mass that will
be converted to energy in the remainder of its
lifetime.
Percentage of mass converted to energy =
Answer:
Percentage of mass converted to energy = 99.9 %
Explanation:
By far most of the solar system's mass is in the Sun itself: somewhere between 99.8 and 99.9 percent. The rest is split between the planets and their satellites, and the comets and asteroids and the dust and gas surrounding our star. Seen from afar (on the scale of distances between stars) the presence of the solar system would not be obvious. We would simply see a normal-looking star. Perhaps we would pick up the presence of Jupiter, which makes up two thirds or so of the solar system outside of the Sun, by mass.

what is aerobic activities
Answer:
Aerobic exercise is any type of cardiovascular conditioning. It can include activities like brisk walking, swimming, running, or cycling. You probably know it as “cardio.”
By definition, aerobic exercise means “with oxygen.” Your breathing and heart rate will increase during aerobic activities. Aerobic exercise helps keep your heart, lungs, and circulatory system healthy.
Aerobic exercise differs from anaerobic exercise. Anaerobic exercises, such as weightlifting or sprinting, involve quick bursts of energy. They’re performed at maximum effort for a short time. This is unlike aerobic exercises. You perform aerobic exercises for a sustained period of time.
Explanation:
Aerobic exercise is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process. "Aerobic" is defined as "relating to, involving, or requiring free oxygen", and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism

Why must 0s always be clearly marked on a motion map?
Answer:
A motion map can represent the position, velocity, and acceleration of an object at various clock readings. ... The corresponding motion map has the points spaced farther apart (because the car would go a further distance in each second), and the velocity vectors (arrows) are longer, because the car is moving faster.
Explanation:
The pressure due to the liquid on an object immersed in that liquid is 4500 Pa
The density of the liquid is 900 kg/m.
What is the depth of the object below the surface of the liquid ?
Answer:
The depth of the object below the surface of the liquid is 0.510 meters.
Explanation:
The hydrostatic pressure ([tex]P[/tex]), measured in pascals, experimented by the object is directly proportional to density of the fluid ([tex]\rho[/tex]), measured in kilograms per cubic meter, gravitational acceleration ([tex]g[/tex]), measured in meters per square second, and depth of the object ([tex]h[/tex]), measured in meters. That is:
[tex]P = \rho\cdot g \cdot h[/tex] (1)
If we know that [tex]P = 4500\,Pa[/tex], [tex]\rho = 900\,\frac{kg}{m^{3}}[/tex] and [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], then the depth of the object is:
[tex]h = \frac{P}{\rho\cdot g}[/tex]
[tex]h = \frac{4500\,Pa}{\left(900\,\frac{kg}{m^{3}} \right)\cdot \left(9.807\,\frac{m}{s^{2}} \right)}[/tex]
[tex]h = 0.510\,m[/tex]
The depth of the object below the surface of the liquid is 0.510 meters.
The depth of the object below the liquid's surface will be
"0.510 m".
Pressure and DensityAccording to the question,
Object immersed, P = 4500 Pa
Density of liquid, ρ = 900 kg/m³
Acceleration due to gravity, g = 9.8 m/s²
We know the relation,
→ Hydrostatic pressure (P) = ρ.g.h
or,
Depth will be:
→ h = [tex]\frac{P}{\rho .g}[/tex]
By substituting the values,
= [tex]\frac{4500}{900\times 9.8}[/tex]
= [tex]\frac{4500}{8820}[/tex]
= 0.510 m
Thus the above answer is appropriate.

The particles of an ice cube at 0°C (represented by the blue circles) come in contact with the particles of Juan’s hand at 37°C (represented by the orange circles). Which diagram correctly represents the temperature of the two substances and the direction of heat flow?
Answer:
its b
Explanation:
The diagram which correctly represents the temperature of the two substances and the direction of heat flow is shown below.
What is heat?Heat is also referred to as thermal energy and it can be defined as a form of energy that is transferred from one physical object to another, especially as a result of a difference in temperature.
During the process of heat conduction, heat is primarily transferred between objects with different degrees of temperature and materials that are directly in contact with each other.
In conclusion, heat is generally transferred from a hotter object (37°C represented by the orange circles) to a cooler object (0°C represented by the blue circles) as shown in the image attached below.
